Integrated circuit.

Thank you.Yes, it can be said that. Only one option must be right.

 

hi 53,
The computers I first worked on, used Triode as Gates and Diodes as 'modern equivalent' diodes

The wording sounds like school wok. Is this question on a test?

Yes.

 

None of the above - Colossus was made mainly out of pentodes

If the question you were given really has the word "Lamp" on it, that is ***very*** bad for your class / teacher / school.

Whatever; in the context of what they meant to say, the correct answer is, as already given away, a).

Hello,

As @AnalogKid said, Lamp is a bad choice.
Better is valve or tube, depending where you are.
Electronic valve give this in google images:
electronic valve
Electronic tube has better search results:
electronic tube
