Computer System Basic Terms

It was once considered that a literate person is anyone who knows how to read and write. Today, that definition is different and it is considered that a literate person is anyone who knows how to read, write and knows the basics of working on a computer. Computers are used today in almost all areas of human activity.

How much we depend on computers and the Internet today is also shown by the fact that e-mail has largely replaced the classic letter, we create documents using computers and exchange them via the Internet, we make phone calls more and more often via the Internet (Viber, Skype)…

These are just some of the reasons why it is important to learn computer science, that is. to become computer literate.
