What is a PC?

A PC is an abbreviation for the word "personal computer". In translation from English "computer" means "calculator". First of all, computers can perform complex computational operations without a human intervention under a given instruction - the so-called program.

Answering the question, what is a PC, we should touch on the history of computer technology. Its beginning was laid back in 1943, when IBM created the machine "Mark-1". The first computers were tube computers. Then they were replaced by transistor computers (electronic computers), then computers appeared with the use of integrated circuits. Finally, they were replaced by electronic computers with schemes of the greatest integration.

The first personal computers, that is, computers intended for individual use, appeared in 1981.

Currently, the computer allows you to carry out not only numerical calculations, but also enables you to prepare books for printing, create movies, music, pictures, manage production and so on. That is, the computer has become a universal means of processing various types of information.

Modern computers are devices for searching, storing, converting, collecting and using information in digital format.

How does the PC work?

When answering the question about what a PC is, you should also specify how the personal computer works. Computers work with software, which consists of application and system programs, as well as programming systems.

The main system program is the operating system that organizes the computer for data processing. It controls all PC devices, exchanges data between various devices and a computer, between a PC and a person, and so on.

The power of personal computers is constantly increasing, the area of their use is expanding. They can be combined in a network, thereby enabling hundreds of users to easily share information. Thanks to e-mail, it was possible to instantly receive or send a letter and other files to people living in other cities and countries.

Areas of use of computers are not limited. For representatives of various professions, this machine has become an integral tool of work. PCs allow for automated management of harmful or complex industries, ensure the smooth operation of complex aggregates, conduct professional retraining of personnel, perform repetitive operations and so on. Users with this smart machine have a lot of opportunities, including communication through the network, improving the quality of education, access to global resources. In medicine, computers allow you to automate patient records, conduct electronic medical records, conduct diagnostics and establish accurate diagnoses. Scientists use computers to model costly and complex experiments. The programs allow you to adjust the data in the projects and monitor the progress of the experiment from the monitor screen. For this, the level of PC ownership in modern scientists should be at a very high level.

In banking, computers are used universally for financial settlements, performing various operations, including processing checks, registering changes in deposits, and so on. Modern banking workers are well aware of what a PC is, because their work is closely related to the use of computers.

In the trade, computers enable you to speed up settlements with customers, keep the quantity of goods under constant control, and maintain an automatic database.

And, of course, the computer is very useful in everyday life. It is used for correspondence with friends, access to the latest news, home bookkeeping, organization of leisure.

Now, I hope you do not have a question, what is a PC and where computers find application. Modern life is difficult to imagine without microprocessors, mobile phones and laptops.
