Answer:
Second Generation: transistors
Third Generation: integrated circuits
First Generation: vacuum tubes
Explanation:
Generations of computers are categorized based on the technologies that were used in them.
Given innovations or technologies are:
<u>transistors
:</u>
Transistors were introduced in the second generation in place of vacuum tubes.
<u>integrated circuits
:</u>
Integrated circuits were introduced in the third generation. An IC consists of multiple transistors.
<u>vacuum tubes:</u>
The very first generation of computers used vacuum tubes to do the calculations. the only drawback was that the tubes used to heat up very soon.
Hence,
Second Generation: transistors
Third Generation: integrated circuits
First Generation: vacuum tubes
