Text 1 - What are computers?
Computers are machines that perform tasks or calculations according to a set of instructions, or programs. The first fully electronic computers, introduced in the 1940s, were huge machines that required teams of people to operate. Compared to those early machines, today’s computers are amazing. Not only they are thousands of times faster, they can fit on your desk, in your lap, or even in your pocket.
Computers work through an interaction of hardware and software. Hardware refers to the parts of a computer that you can see and touch, including the case and everything inside it. The most important piece of hardware is a tiny rectangular chip inside your computer called the central processing unit (CPU), or microprocessor. It’s the “brain” of your computer – the part that translates instructions and performs calculations. Hardware items such as your monitor, keyboard, mouse, printer, and other components are often called hardware devices, or devices.
Software refers to the instructions, or programs, that tell the hardware what to do. A word processing program that you can use to write letters on your computer is a type of software. The operating system (OS) is a software that manages your computer and the devices connected to it. Two well-known operating systems are Windows and Macintosh operating system. Probably your computer uses the Windows operating system.

Text 2 - What is a computer?
Nowadays, in most modern societies, almost everybody has an idea about what a computer is. We depend on computers in every aspect of our lives, whether we know how to use one or not. But, does everyone really know how a computer works inside?
A computer is an electronic machine which processes data and provides the results of the processing as information. There are three basic steps in the computing process. The first one in Input, which consists of feeding data into the computer’s memory. Then comes the processing: the program is run and the computer processes the data by performing a set of instructions. The third and final step is the output furnished by the computer, which allows the user to see the results either in printed form or on the screen.
The world of computers has created a specific language of its own. English words such as software and hardware are used worldwide and have been borrowed by many different languages. Software is information in the form of data and programs, and hardware refers to the electronic and mechanical parts that make up a computer system.
Despite the constant presence of computers in most modern societies, it is a great mistake to believe that everybody in the world is computer-literate, i.e., is familiar with computers and knows how to use them properly. In some contemporary societies, many people still have no idea about the existence of computers, and even in the so-called developed countries, there are lots of people who do not know or do not care about what a computer is.
