Ex.9. Answer the questions:

1) What were the most important facts for the development of electronics?- The quick development of electronics began with the invention of transistors. They replaced electronic tubes due to their numerous advantages. One of the main advantages of the transistors in comparison with the vacuum tube is absence of filament power loss.

2) Why could not early transistors satisfy the needs of the growing high0spedd computers industry? One of the principal causes of damages in electronic circuitry is high temperature. The heat causes breakdown of tubes and other circuit elements that are very sensitive to this influence. The transistor, on the other hand, does not heat its surroundings

3) What is the major difference between electronic systems and microelectronic devices?

 

IV. Writing

Ex.10. Write the essay on the topic Computer role in todays life

The twenty first century is a century of technologies, computers and technology. It is well-known that the computer has become one of the main ways of getting information. Some people cant live without it, but other thinks computers have a bad influence. Whose opinion is right?

 

My point of view is the following. Firstly, the computer informs us about various things. Secondly, you can travel to different countries and at the same time sitting in front of a computer screen. It is very comfortable. Thirdly, you can use a distance learning. This is a great leap of progress.

But some people are against computers. Firstly, they thought that we can work without computers, because it breaks our eyesight. Secondly, we get a lot of unnecessary information, for example a promotion. It distracts when you are so busy.

But I do not agree with this people. To preserve the health, you should: firstly, ventilate the room; secondly, take a timeout. That you do not get useless information, you can change the computer tuner.

All in all, I want to say that I am for computers. I believe that computers can materially do our work easier and make people more educated. Our future is in our hands.
