The first generation computers use VACUUM TUBES : Vacuum tubes consists of a glass bulb and wire.
The wire is used to carry data from electronic signals.
This computers were large, expensive.
ENIAC was the first generation computer -
The second generation computers used transitors instead of vacuum tubes
-
The third generation computers used INTEGRATED CIRCUIT: Is a small transistor but they have more capacity.
This computers are faster, cheaper and smaller. -
The fourth generation computers used microprocessors : consist of a small silicon chip on which thousands of circuits are placed.
This computers are smaller, portable and cheaper and they use less electricity and produce less heat -
This generation use the ARTIFICIAL INTELLIGENT: Robots work on this technology
