Introduction Due to the high speed of light - 300, 000 km per second computers can do calculations much faster than a humans. Because electrom. Waves to wipes spread with light speed. Due to the small size of transistors – 1 -5 mkm - modern computers take up little space and allow everyone to store data conveniently. Transistor is conveniently main element of computer.
Computers in sciense The computers in lab help to handle devices. If you want to set the required voltage, you may use the Gann’s diode and a computer to control it.
Computers in education Nowadays people can study using computers. For example, if teacher is far from his students, he/she can still give lessons to them in such a comfortable form as a webinar. Students can see the teacher and can ask questions using chat.
Computers in home. The sociological survey shows that average people spend 3 hours on the computer every day. It means that during all the life a person will spend 7 years!
Expeсtations Computer and mechanisms in the future may help save the lives of sick people at a distance, allows the surgical operations with mechanical arms and camcorders. Perhaps people will create HD 3 D models of cities and planets and among them will be flying.
Conclusion Computers have both advantages and disadvantages. On the one hand, they help people to store data and operate with it. On the other hand, peoples spend too much time using the Internet.
