The average person believes that a computer can do anything. But an ordinary PC, located in an apartment or at work in an office, can solve a limited number of tasks. He is far from real super machines used by professionals. Therefore, an ordinary person does not quite correctly understand what the computer is for.
What is a computer?
A computer is a systematic device whose purpose is to solve certain problems through sequential operations. It is used in all spheres of human activity. Computers come from computers (electronic computers), and they have come a long way through decades, constantly changing and improving.
Computer purpose
The initial goal of a computer is to solve problems by computing. In the modern world, this technique is used in many areas of human life. Consider what the computer is intended for.
Leisure and entertainment
Users can listen to music in different sound formats, copy it from a computer to a disc, and if they have the right programs, create it. It is also convenient to watch movies using a PC, and having a large monitor and powerful stereo speakers can completely replace a home theater. On the computer you can play games that have a myriad of all kinds and all genres (strategies, shooters, arcades, etc.). You can read books directly from the screen. But the most interesting thing is that having a powerful computer and certain programs, you can create games and cartoons.
Internet access
If you have access to the Internet, then there is a connection with the outside world. On the World Wide Web you can chat with people from different countries, read any information about everything in the world, play network games and much more. This use of a computer by modern man is the most common.
Work
You can work on a computer, compose documents, check spelling and spelling, calculate and solve problems, and much more. The most interesting thing is that you can find work on the Internet, but it is not as easy as it sometimes seems at first glance. Here, too, you need to improve and go to the intended goal.
Communication
In the modern world, a computer combines many means of communication. Among them are e-mail, telephones, faxes, messages on social networks, forums, chats. All this happens through the Internet and directly through the computer itself.
Pay bills and purchases
On the Internet there are a huge number of stores where you can buy anything. And besides, the prices there are lower than in ordinary retail outlets. Also, in large cities, utility bills, Internet and mobile communications come by email, which is very convenient for modern people.
Storage and Deletion of Information
Depending on the size of the hard drive's memory, certain volumes of information can be stored on it. Photos, videos from life, as well as your favorite music and movies - anything will be on your computer.
Computer in various areas of human life
Knowing what the computer is intended for, one can understand that in modern society it is necessary in various spheres of human life. For instance:
- in medicine (epidemic calculations, patient incidence databases, research results, etc.);
- in education (with its help you can print texts on a large number of pages, view video tutorials, read books, pass tests, perform calculations and much more);
- in the law enforcement sphere (creation of documentation of protocols, operational-search activities, databases of crimes committed and file cabinets for criminals, analysis of substances in the laboratory of forensic scientists, and so on);
- in the field of art (drawing, creating music, animation, games, programs, writing books and the like), etc.
How to use a computer
A ready-to-use computer is a system unit plus speakers, a monitor, a keyboard, a mouse, and a network filter. You also need to make sure that the Windows operating system (or another) is correctly installed on your machine. In addition, there are additional devices: a modem, fax, printer, webcam, etc. Everything is a little different with a laptop: it is not as large as a PC, and many devices are built into it directly, and it can work without connecting to the network. To start the computer, you need to make sure that the surge protector is turned on and click on the appropriate button. It is located on the system unit and is marked with a special symbol. This will be followed by turning on the computer, and then loading the Windows (or other) OS. Icons are located on the desktop, they are small signed icons. To learn how to use a computer to the full, you need to master it well. It is worth entering by clicking on the corresponding icon in “My Computer”. Depending on how the hard drive is divided into BIOS, a machine may consist of several hard drives. They can store information of various kinds: music, films, books and so on. In order to systematize everything (put things in order and put everything in order), you can learn how to create folders inside these disks and then give them the names you need. How to do it? By clicking on the right mouse button in an empty place (not on the icon), select "Create" and the line - "Folder". Voila, the new folder is ready! To rename it, double-click on the name and the text of the name will be highlighted, press the Backspace key and the old text will be erased, now you can safely enter your folder name using the keyboard. You can do the same with other files.
Required Programs
If you have already figured out what the computer is for, you need to take good care of it. Often, for its proper functioning, a number of programs are needed:
- Antivirus is a very important program so that your computer does not become infected with trojans and viruses.
- Archiver - for compressing documents.
- The Microsoft Office complex - everything for working with a computer to the fullest: to print, calculate, create presentations, etc.
- Various codecs for watching movies and listening to music.
- Additional software such as DirectX and Microsoft Visual C ++: so that games run perfectly on the computer.
Over time, having mastered the technique of using a PC, you can become an ace in this matter.
