Match each generation of computers with its features. tiles used vacuum tubes used transistors used integrated circuits pairs second-generation computers arrowboth third-generation computers arrowboth first-generation computers arrowboth

The correct answer is the following.

The correct matches are:

1.- First Generation of Computers: vacuum tubes.

2.- Second Generation: transistors.

3.- Third Generation: integrated circuits.

There is also a fourth generation that uses computer chips.  

In the beginning, computers were so big and used vacuum tubes to operate. It was the period from 1940 to 1956. They used magnetic drums for the memory. We can talk about a second generation from 1956 to 1963. Transistors replaced the vacuum tubes. This allowed computers to work in a faster way. A magnetic core replaced the drum. The computer had a longer useful life. The third generation appeared from 1964 to 1971. These new models used integrated circuits. The new machines were affordable to people to get his computer at the office or home. They were smaller and processed information faster. The fourth generation is the one we use today. They use silicon chips and the amount of information they processed is incredible.
