D Correct answer
Explanation

Fourth generation computers, emerging in the 1970s, are characterized by the use of microprocessors, which integrated thousands of ICs onto a single chip.

Multiple choice

What is the major difference between Moore and Mealy machines?

  1. The output of the former depends on the present state and present output.

  2. The output of the former depends only on the present state.

  3. The output of the former depends only on the present input.

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In a Moore machine, the output is determined solely by the current state. In a Mealy machine, the output depends on both the current state and the current input.
