How To Compress A Word File

Did you notice that the size of a Word document that you have to send via email are well above average and so would like to "lighten" a bit '? I do not promise anything, but maybe something can be done.

Follow the advice I am going to give you and find out how to compress a file Word optimizing the content. If you're lucky and the document you want to compress is not already maximized, you'll get good results. Let's get started!

If you are looking for a solution on how to compress a Word file, one of the most effective solutions that you can implement is to compress the images contained within the document and save it in DOCX, which as we know is lighter than the DOC Word 97-2003. I know that may seem like a difficult thing, and yet I assure you that it is a breeze.

All you need to do is open the file to be compressed in Word and select any of the images contained in it. Then went on the Format tab that appears at the top right and click Compress Pictures (located in the upper left).

In the window that opens, put a check mark next to the item in all the images of the first document and click on the OK button and click Apply to start the process of compression of the photos contained in the document.

When the operation is completed (it will take a few moments), grant to save the file in DOCX clicking the File button located on the top left and selecting Save As from the menu that appears. In the window that opens, set the option Word Document in the Save as type drop-down box, type the name you want to assign to the document in the file name field, select the folder in which to store the file and click the Save button to complete ' operation.

Now check the size of the document before and after the changes: if everything went the right way, the DOCX with compressed images should be lighter than the original file. But do not expect miracles, I recommend it. If the original document does not contain a lot of photos and is already in DOCX, the weight loss will be quite modest.

If you do not need to compress a single Word file, but a large number of documents at a time, you can turn to solutions like FILEminimizer Suite. It is a commercial software that allows you to compress files to Word, PowerPoint, Excel, PDF files and digital photos quickly and easily by operating on multiple files in series. The software is a fee but it is available in a free trial version that allows you to test all the functions for a period of 30 days.

To download FILEminimizer Suite on your computer, connected to the Internet site of the program and click 'Download Free Trial. Download is complete open, double clicking on it, the file you just downloaded (FILEminimizerSuite-setup.exe) and in the window that opens, click first on Yes and click Next.

Then accept the conditions of use of the program, putting the check mark next to accept the terms of the license agreement, and click Next first five consecutive times and then click on Install and Finish to complete the installation process and start FILEminimizer Suite.

In the window that opens, click the Continue button to access the Test main application window and drag within the latter documents to be compressed. Then moves the bar compression settings on the quality level you want and click the Optimize button file to start the file compression.

How To Delete Temporary Files

Whether you like it or not, the hard disk of your PC are accumulating a lot of temporary files. Even now, at this very moment, I bet your system it is creating someone. Are you worried? You do not have, is a normal thing!

Temporary files are data that the operating system and applications create as a backup, for example, to be able to undo the changes made to a file, or as a "shortcut" for quick access to certain information. They include lists of most recently opened files (technically called MRU), backups of Windows updates, history and browser cache, thumbnails of photos and video, and the list could go on and on.

As mentioned earlier, the presence of this data on your computer is normal, however, in some cases it is advisable to delete temporary files to free up disk space or correct small malfunctions that may be encountered in everyday use of the PC (eg. The failure to display of thumbnail images in the Windows Resources or slowdowns browser). Let's see how you do.

How to delete temporary files on Windows

Let's start seeing how to delete temporary files on Windows. For this purpose you can use various tools but I shall consider only two: the Disk Cleanup utility included "standard" in all versions of the Microsoft operating system and the free CCleaner. Both are simple to use.

Disk Cleanup

To start the cleaning tool disk in Windows, look for it in the Start menu (or in the Start Screen) of your PC and click on its icon. Then select the types of files to delete and click the OK button first and then on Delete Files to start the process of deleting data.

Normally, the application to the disk cleanup removes data from the navigation of Internet Explorer, the temporary files related to Windows Error Reporting, previews of photos and videos in the Windows resources and temporary files of third-party applications parts (you can select each item with the mouse to find out in detail what it refers to).

To expand its operation and delete other system data, such as files not critical Windows Defender, you can click the button Clean up system files and wait for the software to restart from only showing you the updated list of files to remove .

How to Export Contacts From Gmail

You have decided to leave Gmail or to open a secondary email address and would like to transfer to it all the contacts in your Google address book? It is not difficult as you think. Just take advantage of the special transfer function of the contacts and you're done.

To find out how to export contacts from Gmail, read the directions in the guide I am going to propose and put into practice. By doing so, you will be able to transfer your entire address book from Gmail to any other service or e-mail client with minimal effort. Let's get started!

If you want to learn how to export contacts from Gmail, the first step you need to do is log in to your mailbox license plate Google, click on the item Gmail ↓ placed in the left sidebar and select Contacts from the menu that appears.

On the page that opens, click the More button located at the top and select the Export item from the menu that appears. At this point, put a check mark next to All contacts, select the format in which to export the names of the three options available (Google CSV format, CSV format Outlook or vCard format) and click on the blue button to download Export the file with a list of all your contacts on your PC.

You can also export contacts from Gmail that are part of a particular group. Just follow the procedure that we have just seen for the export of all contacts, put a check mark next to the group instead of All contacts and select the contact group to be exported from the menu drop down.

If you want to export contacts individual, choosing them manually from the Gmail address book, you have to go into Gmail> Contacts, put the check mark next to the names you want to export, click the More button and select Export from the menu that appears. In the box that opens, make sure there is a check mark next to the item selected Contacts and click the Export button to save the file with the selected contacts on your computer. Easy, right?

How To Speed Up Your Computer

Without constant maintenance, all PCs equipped with the Windows operating system end up being slow and unresponsive. Fortunately, however, these problems can be solved easily without resorting to technical or expensive software for a fee. Just use the "tools of the trade" fair and even the most seemingly hopeless situations can be arranged very well.

If you find yourself in such a situation and you are irritated by the slowness of your PC, read the advice I am going to give you and find out how to speed up your computer with programs totally free and easy to use even for someone who is not an expert informatics. You'll see, is just over ten minutes to feel the first positive effects on the performance of Windows.

If you want to find out how to speed up your computer, you should start from the hard disk: free as much space as possible by eliminating programs that no longer use and clutter. Of course you will not be alone in this task but you will be helped by two aides trust, CCleaner and Revo Uninstaller. The first allows you to uninstall programs from PC in a "deep", ie removing from hard disk and system registry all traces that these would leave after uninstalling standard (one performed via the control panel of Windows). The second is famous, is a free program that allows you to optimize your computer by deleting all unnecessary files / temporary present in it and correcting errors in the system log. Let's see how to use them quickly.

To completely uninstall a program with Revo Uninstaller, you have to do is start it, select the program you want to remove from your PC by double clicking on its icon and answer Yes to the confirmation prompt that appears. At this point, you have to put a check mark next to Moderate, click on the Next button and normally carry out the uninstall program (always clicking Next or Next). When finished, click the Next button and wait Revo Uninstaller examine hard drives and registry system for residual traces of uninstalled program. If you find the track, put a check mark next to them and click on the button to remove them from your PC, so you're sure getting rid of 101% of the selected program.

Use CCleaner is just as easy. You have to do is start the program and click on Scan to start the search all files unnecessary / temporary on the hard disk of the computer. If you are an experienced user, you can manually select items to be removed from the list located on the left, but in most cases the default settings are fine. After the search, first click on Start cleaning and then OK to delete all the junk files found on the disc. Then go to the Log tab and click the Find button to start the search problems of obsolete and corrupt keys within the Windows registry. After scanning, click on the Repair selected and creates a backup copy of the registry (to be restored in case of problems) by answering Yes to the backup request. Now wait a few seconds and Ccleaner should complete its cleanup work.

Using Revo Uninstaller CCleaner and are already well advanced in the process to make your computer faster, but not enough. If you want to return Windows snappy like the good old days, you have to act in more depth on the registry and use another free program called ad hoc Wise Registry Cleaner that not only provides to eliminate problems from the register securely but also defragments the content of the latter so as to make the system more flexible.

To optimize your registry with Wise Registry Cleaner, you have to start the program and click on the green Scan placed in the upper right corner to start the scan of the Windows registry (the first time the software you must also set the Italian language by putting the sign of tick on the appropriate heading). A check is complete, click 'Cleaning and the program will fix all problems found. At this point, go to the tab and click on Defragment Analyze to start before the control and then defragment the registry. To complete the process will require a reboot of the PC.

If after use of the programs that I just reported the situation of the PC does not seem to be improved a lot, you have two other weapons to try: the deactivation of the programs set to start automatically each time you log in Windows and a malware scanner to try Any malicious software that slows your computer.

To speed up your computer by removing from the automatic programs that are not needed, ul click the Windows Start button, type msconfig in the quick search bar and press the Enter key on the PC keyboard to access the utility of the system configuration. In the window that opens, select the Startup tab, remove the check mark from the name of the programs that you do not want to start every time you log on to Windows first and click Apply and then OK to save the changes.

\As for viruses and malware, however, the only advice I can give you is to use good products, update them often and have a good system scan with the latter. If you seek an antivirus and antimalware a good standard and do not want to spend money on the purchase of commercial solutions, heads straight on Microsoft Security Essentials and Malwarebytes Antimalware and you will not regret. The first is a free antivirus product from Microsoft lightweight and powerful at the same time, the second is a free anti-malware program (which runs continuously in the background but you have to manually start the scans) that allows you to remove from the PC threats like trojans, keyloggers and other types of malicious software that can slow down your system. If you want a detailed guide on how to use it, read my article on how to remove trojan.

Finally, remember that if you are using Windows XP, you also need a good program for disk defragmentation, as what I recommended in my guide on how to defragment, as the integrated utility default in the operating system is not working automatic (as does that of Windows Vista and 7/8) and does not act in a very effective manner. And now enjoy your computer super-fast!

Software Engineering

Software engineering is the application of a disciplined, systematic, quantifiable approach to the development, operation and maintenance of software, 1 and studying these approaches, ie, the application of engineering to software.2 Integra mathematics, computer science and practices whose origins are in the ingeniería.3

The most recognized definitions, formulated by renowned authors are cited:

Software engineering is the study of the principles and methodologies for the development and maintenance of software systems.

Software engineering is the establishment of the principles and methods of engineering to obtain profitably software that is reliable and works on real machines (Bauer, 1972).
Software engineering is the application of a systematic, disciplined and quantifiable approach to the development, operation, and maintenance of software.

In 2004, the US Bureau of Labor Statistics (Bureau of Labor Statistics US) counted 760,840 software engineers computadora.4 The term "software engineer", however, is used generically in the business environment, and not all who work in the position of software engineer really have engineering degrees from recognized universities.

Some authors consider that "software development" is a more appropriate than "software engineering" to the process of creating software term. People like Pete McBreen (author of "Software Craftmanship") believes that the term implies IS levels of rigor and testing processes that are not appropriate for all kinds of software development.

Interchangeably the terms "software engineering" or "software engineering" are used; though less common also usually referenced as "software engineering" .5 June 7 In Latin America the most commonly used terms are the first two.

The creation of software is an inherently creative process and software engineering to systematize this process in order to limit the risk of failure to achieve the objective, through various techniques that have been proven right based on prior experience .

The SI can be considered as applied to software engineering, that is, systematic and tool presets means, applying them efficiently for optimal outcomes manner; objectives which always seeks engineering. Not only troubleshooting, but rather taking into account the different solutions, choose the most appropriate.

Value Of Information

The information has great impact on decision-making. Although not an absolute value, its value is related to its user and the situation of use.

The normative value of information: Refers to a priori knowledge or preliminary we have about the occurrence of events which are relevant to our decisions (probabilistic).

The realistic value of information: The information recognizing that supports decisions. Actions taken affect performance achievements.

The subjective value of information: Reflects the impression comprised of people for information.

Reduced inventory levels in the line of credit, man hours, increased sales and reduced maintenance costs: Ø Tangible benefits.

Intangible Benefits: Improved decision-making processes; broadens the horizons of planning; extending information bases for decision-making; facilitates data integration.

Investment in information technology does not lead anywhere unless accompanied by an intelligent use of information technologies allow us to manage.

The success, the return on investment in the application of information technology in an organization depends on to help better utilize the information generated in the process. The value of technology is therefore the value that is derived from better use of information captured and managed with technology.

Network

Objective Network

The network is geared to meet the general needs of the company, and tries to meet current communications standards; also must have technology to achieve the lowest possible price, trying to reduce administration and maintenance costs through the implementation in the form of a network of reliable and efficient communications.

As a network, the main objective is to share resources such as printers, software (applications), manufacturing equipment, etc.

The network must be Managed properly, so it can grow according to changing business needs

You must provide a high level of safety in the transfer of information through checks and passwords or passwords, in addition to a transmission medium stable and reliable

To provide stable service fast data transfer

Transfer costs should be minimized so that is a plus for the company network deployment

Sharing resources such as printing documents and information transfer, since the latter is the most precious resource for any company.

Email access for network users.

Justification Network

The implementation of the network allows us to be able to share large amounts of information to travez of different programs, databases, etc. So that it is easier to use and upgrade.

Reduces and even eliminates duplication of data.

Allows you to use email to send or receive messages from different users on the same network or even different networks

The network contacts a server. Thus the server provides resources being accessible to each of the computers connected to the network. The server can improve security and control information used allowing the entry of certain users, accessing only to certain information or preventing modification of various data.

Hardware

The hardware will be comprised of the physical devices that are implanted for network operation. Then shall mention them and their characteristics as well as a table of prices and units required for the development of the network.

Software

The choice of operating system was based on four stability to provide the system, since the operations to be undertaken need security and reliability.

What is Internet

Some years ago, when the Internet started nobody could imagine that there would be what today is. It began with the aim of exchanging information and do research in collaboration between different research centers scattered throughout the world. Today, the goal is entirely commercial, while the Internet2 was created to try to meet the goal initially drawn to the Internet.

The Internet has revolutionized the way technology is used today. Introduced a number of standards and multiplied almost five to ten times the proliferation of applications to be used by the common people. The restriction of having to hold a degree in computing or systems to handle a computer and access to information was deleted.

Through the viewfinder you have access to the new world of information now they not only "at your fingertips" as more than a decade it announced a major technology company worldwide in their advertising does, but "within reach Fingers WORLDWIDE ". The viewfinder and IP technology (communications protocol) eliminated the most prevalent reason to avoid massive deployment of technology: the need for the "user" were in a controlled environment.

The ease of use of this technology is even greater than that presented a Fax machine recently entered the business world. And a revolution was considered in streamlining communications. There was no card that did not include a fax number. Today, there is no excuse for a business card does not carry the email address of the owner.

Technology is so overwhelming, that the language barrier, waylaid new technology that allows for simultaneous translations of the content. Each obstacle new technology comes out to remove the barrier to deployment thereof. Including lack of standards between the two largest producers of viewers, has not prevented its development.

Since the Internet is part of everyday life. You have to check mail frequently, both office and staff, the state economic sector interest in visiting appropriate Web pages is reviewed. The market research information is obtained, it interacts with customers and suppliers, entertainment is sought, friendships are made and partnerships are built.

There are already two tests of "formalization" of the Internet as a medium and industry. Recently, the Dow Jones company that makes equity indexes traded on stock exchanges, created the Dow Internet Index which forms a portfolio of approximately 40 stocks, all representative or the Internet service sector (eg AOL) or Trade Mail (Amazon, for example)

Moreover, we announced in a previous report, the firm Swatch has "created" the Internet which divides time 24 hours a day in 1000 beats, giving the same time worldwide.

Both aspects eliminate geographic, language and cultural barriers up. The Internet has become embedded in everyday life and every day more people are accessing this technology, because with such low prices of new technology, there is no excuse not to use it.

You can not avoid mentioning that for those who are designing or have already designed their presence on the Internet, it is important to check whether the use of the information placed at the disposal of visitors resemble what in real life I would get. I recently wanted to obtain the extract from my bank account to reconcile a balance, and my first source was the bank itself. I printed a copy of the latest moves. Since this information could not reconcile and I required information above, I forwarded it to the Internet. Sure ago my bank presence in the "electronic banking". What was my surprise when to apply the extract from the Web page of my bank, I was informed that he would be sent by physical mail to my address! when it was expected to refer to the same display the required information.

In conclusion then, and according to one of the predictions for 1999, the Internet increasingly must copy the expectations of what you can get in real life, but also on this expectation, create a series of services exclusively reserved for the virtual world.

The Google search

The Google search or web search engine Google (in English Google Search) is a search engine on the web owned by Google Inc., is the most used search engine on the Web,

 receives hundreds of millions of queries every day Through its various services.

The main objective of search engine Google is search for text on web pages, instead of other data, was Basicaly developed by Larry Page and Sergey Brin in 1997.

Google search engine provides at least 22 special features beyond the word. These include synonyms, weather forecasts, time zones, stock quotes, maps, earthquake data, movie, airport information, home listings and sports scores. There are special features for numbers, including intervals (70 .. 73), rates, temperatures, unit conversions and coins ("10.5 cm in inches"), calculations ("3 * 4 + sqrt (6) -pi / 2 "), package tracking, patents, telephone area codes, and translation of pages displayed.

The order of search results (ghits by Google hits) on Google results pages which are based, in part, on a priority rank called "PageRank". The Google search provides many options for personalized search using Boolean operations such as exclusion ("-xx"), inclusion ("+ xx"), alternative ("xx or yy") and wildcard ("x * x ")

The frequency of use of search terms has reached a level that may indicate more economic, social and health.

 Data on the frequency of use of search terms on Google Trends (available through Google Adwords, Google Trends and Google Insights for Search) show that no correlation between influenza outbreaks and unemployment levels and provide information faster than traditional methods of reporting and government surveys. [citation needed]

On May 12, 2009, Google announced that it would analyze the micro formats hCard, hReview and hProduct to increase search result pages with what they called "Rich Snippets" .

In June 2011, Google introduced "Google Voice Search" and "Google Images" features that allow users to search for words when speaking and imágenes.

In late June 2011, Google changed the design of your home page in order to promote the use of tools sociales. links advertising, business partners and company information was brought to the lower edge of the browser.

 One major change was to replace the navigation bar classic black. The digital creative director of Google Chris Wiggins explains: "We are working on a project to provide an experience of new and improved Google and in the coming months will see more changes in our appearance."

Electronic Commerce (e-commerce)

Electronic commerce, also known as e-commerce (electronic commerce in English), containing  the selling and  buying of products or services through electronic channels such as internet and other computer networks means.

 Originally the term was applied on the execution of data transfar through electronic means such as electronic data interchange, however with the advent of the Internet and the World Wide Web in the mid-90s began to refer mainly to the sale of goods and through Internet services, as a way of using electronic means, such as credit card payment.

Most e-commerce consists of the buying and selling of products or services among individuals and companies, however, a considerable percentage of electronic commerce is the acquisition of virtual goods (software and derivatives mostly), such as access to Content "premium" of a website.

Digital and Analog Computer

DIGITAL COMPUTERS

They are computers running counting numbers and making logical comparisons between factors that have numerical values.

Features of Digital Computers

Its operation is based on the count of values that are entered.

This type of computer must be programmed before being used for a specific purpose.

They are general purpose machines; given a program, they can virtually solve all kinds of problems.

They are precise, provide exactly the right answer to a specific problem.

These computers have a large internal memory, which can be introduced million characters.

These computers are the most used. At present 95% of the computers used are digital gave his very useful commercial and educational level scientist.

ANALOG COMPUTERS

Analog computers not directly computed, but constantly perceived values, signals or various physical quantities.

Features Analog Computers

They are the fastest computers. All computers are fast but the direct nature of the circuits that make up the fastest.

These computer programming is required; calculation relations are constructed and they are part of.

They are machines for specific purposes.

Dan approximate answers, as they are designed to electronically represent some sets to give you the real world, so their results are close to reality.

These are generally used to monitor the conditions of the real world such as wind, temperature, sound, movement, etc.

HYBRID COMPUTERS

Hybrid computer is a system built a computer and an Analog Digital, connected through an interface that allows the exchange of information between the two computers and the development of their work together.

LED Light Emitting Diode

The ledes are used as indicators and in many lighting devices. The first ledes emitted low-intensity red light, but modern devices emit high brightness light in the infrared, visible and ultraviolet spectrum.

Because of their ability to operate at high frequencies, are also useful in advanced communications technologies and control. Infrared ledes also used in remote control units of many commercial products including audio and video.

Features

Ways to determine the polarity of a LED insertion [edit]
There are three main ways of knowing the polarity of a LED:

The longest leg will always be the ánodo.3
On the cathode side, the base of the LED has a flat edge.
Within the led, the board indicates the anode. Can be recognized because it is smaller than the anvil, indicating the cathode.

Advantages

The ledes present many advantages over incandescent light sources and fluorescent, such as low power consumption, a longer life, reduced size, vibration resistance, low heat emission, no mercury (which when exposed in the environment is highly harmful) compared with fluorescent technology, not create high magnetic fields and magnetic induction technology with higher residual radiation which is created for the human being; They reduce noise on power lines are special for use with photovoltaic (solar panels) compared to any other current technology; not affected by the intermittent illumination (ie can function as strobe lights) and this does not reduce its average life, you are special to systems antiexplosion because they have a strong material, and in most colors (except blue ledes ), have a high level of reliability and durability.

Starting time

The ledes have the advantage of a very short power (less than 1 millisecond) compared with high-powered lights such as luminaires high intensity sodium vapor, metal halide, halide or halogenated and other systems incandescent technology.

Variety of colors

Ledes1 different colors.

The great variety of colors that occur ledes has allowed the development of new electronic displays monochrome text, bicolor, tricolor and RGB (full color displays) with the ability to playback video for advertising, informational or signaling purposes.

Computer Practice And Theoretical Computer Science

There are fringe people who confuse the computer with vocational areas that typically involve the use of application software and which include the simple use of programs for the office, surfing the web or gaming. The computer instead sees text editor, browser, and video games as mere tools for work or leisure. What is interesting, in computing pure, is not knowing how to use the so-called application for how they present themselves, but rather to understand, for example, through the analysis of the source code, structure and possibly knowledgeable improve with the use of algorithms efficient under different criteria (memory usage, number of instructions, parallelism, ...).

In universities there are departments and Science courses. A computer should always have a genuine interest in the theoretical foundations of computer science; which then, by profession or passion, often face the developer of software is possible but, being able to leverage their problem solving skills in various areas, it is not obvious. In any case the computer, at least in its application part, is a discipline strongly oriented to problem solving.

The theoretical foundations of the discipline then descend directly from mathematics (discrete mathematics), to which the computer is closely related, and it is also for this reason that the study of computer science has recently gained attention in the multidisciplinary try to clarify or justify processes and complex systems of the real world, such as the ability of the human brain to generate thoughts from molecular interactions (studies belonging to bioinformatics).

In particular, the computer goes into several smaller fields: the study of formal languages ​​and automata, which also covers the compilers; the study of the computational complexity, especially for minimizing the number of instructions to be executed for the resolution of a problem and the search for approximate algorithms for solving NP-hard; Cryptology, the science that studies the methods to make a message incomprehensible to anyone who is not in possession of a key to the message itself; the theory of codes, used for data compression or to increase the integrity of the data; operations research, to provide mathematical tools to support decision-making activities; computer graphics, divided in turn into bitmap graphics and vector graphics; quoting only certain subfields.

Telecommunications

The foreign word "telecommunications" belonging German word is telecommunications. However, it is used since the mid-1990s practically only to military facilities and civil protection (civil protection has recently been often of "information and communication" (ICT), speaking) and is almost completely disappeared in the vernacular, as particularly the Use this field operating companies, the word "telecommunications".

In a narrower sense is understood as a data exchange using electrical engineering, electronics, wireless technology and other technology transfer of modern telecommunications today. The first telecommunication services in this sense were called telegraph (telex) and telephony, and remote signaling. Before the advent of computers, there were already designated as telecontrol data transmission services to control plants.

"Telecommunications is the technical process of sending, transmitting and receiving signals by means of telecommunications;" For the purposes of this definition also therefore also radio and TV (analogue and digital), fax, mobile telephony and the Internet and many examples in which also the German lawmakers defined in the Telecommunications Act and used in other legal norms notion of telecommunications.

Telecommunications equipment "technical devices or systems that send messages identifiable as electromagnetic or optical signals that carry, convey, receive, control or can control."telecommunication facilities are now a fundamental part of the infrastructure. For this reason, in order to avoid their spatial disparities providing a common task of spatial development (ie, in practice, a state task). Since the beginning of liberalization (in Germany since 1998) Telecommunications services are provided in competition, primary care is provided by a universal service obligation.

Graphic Designers

Graphic designer is a professional who works in the field of visual communication. His work is mainly to create visual objects, intended to be printed, published or transmitted via electronic media in order to communicate a message to the public in the most simple and effective, through text and images.

The primary responsibility of a graphic designer is the arrangement of items in the most simple and functional as possible. It is also able to take personal responsibility for design and art direction and to provide technical advice at all stages of the creation of a product.

Graphic designers are professionals in several disciplines, are communication experts, and often are also photographers, printers, web designers. They can work in various environments: in professional studios, advertising agencies, in the offices of the graphical editors of newspapers or magazines, publishing houses or domestic companies, or as a freelancer, working with agencies, companies or individual clients.

Types Of Computer

Central unit and personal computers

The modern general purpose personal computers have always UNIA Central. And because, thanks to the advent of microelectronics, today the level of integration of logical and functional components of the computer is very high (so hardly the processing unit that oversees all the functionality of the computer is a hardware lock him). And because, even when all the main hardware components of the personal computer constituting a single block, the personal computer is always equipped with several ports for connecting external devices (such as the printing unit, the disk drive, the modem, etc.) optional (ie not included in the sales package of the personal computer).

Central unit and desktop computer 

In desktop computers the central unit includes most of the major components of the logical-functional computer and the power supply. Excluded external devices not essential to the operation of the computer such as the printer or monitor audio. If the computer is not a computer all-in-one, the central unit does not include either the main user interface output, the display, which is inserted in a separate block: the video monitor. If it is an all-in-one computer, the display is also included in the central unit. The main user interface input, the keyboard, it can either be a separate block, is to be included in the central unit (such as in the home computer). The mouse instead always constitutes a separate block.

CPU and notebook computer

The central unit (left) and the hard disk (right) of a notebook computer
In the notebook computer the central unit includes all major computer hardware. In such computer is referred to as central unit only as a consequence of the fact that they are always equipped with several ports for connecting external devices (usually optional). The central unit is also equipped with autonomous power supply thanks to rechargeable electric batteries integrated in the central unit.
