Computer is extremely multifunctional appliance. Either it is a complex calculation of some mathematical tasks or large text word processing, Hi-Fi-quality music composing or high-definition video watching computer is a very useful and labor-saving gadget. I study on my PC, entertain myself during the free time. It is a great possibility to easily develop different skills yourself with the use of Internet, containing immeasurable amount of helpful information like encyclopedias, teaching programs, smart guides and much more. At all this is available only through the computer.

But if we are tired, we can stop any place to have a rest and snack. There many fast food cafes along the roads. We can bye necessary things and to stay at night in small camping. But there are some disadvantages of having a car. Fist, they are very expensive in exploitations. Second we can’t use our car if it is very cold in the street.
