Exercise 7. Translate the following text in a written form. Use a dictionary if necessary.

 

A desktop computer is a small machine that has a screen (which is not part of the computer). Most people keep them on top of a desk that is why they are called ‘desktop computers’. Similar in operation to desktop computers, laptop computers are miniaturized and optimized for mobile use. Laptops run on a single battery or an external adapter that charges the computer batteries. They are enabled with an inbuilt keyboard, touch pad acting as a mouse and a liquid crystal display. Both laptops and desktops are called personal computers, because one person at a time uses them for things like playing music, surfing the web, or playing video games.

There are bigger computers that many people at a time can use. They are mainframes. Large organizations use mainframes for highly critical applications such as bulk data processing. Most of the mainframe computers have capacities to host multiple operating systems and operate as a number of virtual machines. They can substitute for several small servers.

There is another type of computer, called an embedded computer. An embedded computer is a computer that does one thing and one thing only, and usually does it very well. For example, an alarm clock is an embedded computer: it tells the time. Embedded computers cannot be programmed. Some mobile phones, automatic teller machines, microwave ovens, CD players and cars are examples of embedded computers.
