  1. first generation

  2. second generation

  3. third generation

  4. fourth generation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

NCR 395 was a third-generation computer that used integrated circuits (ICs) instead of discrete transistors. Third-generation computers (1960s-1970s) were characterized by the use of ICs, which made them smaller, more reliable, and more efficient than their second-generation transistor-based predecessors.

Multiple choice

What is meaning of the term debug?

  1. To improve the language

  2. To remove errors from program

  3. To remove virus

  4. None of these
