Problem of the Day

Problem:

An early minicomputer, the DEC PDP-11

The hardware that makes up a computer typically includes:

  1. central processing unit (CPU)
  2. Input and Output interfaces
  3. memory (RAM and permanent)
  1. I only
  2. II only
  3. I and II
  4. II and III
  5. I, II, and III

Show solution:

The correct answer is e.

The CPU performs calculations as needed to process instructions stored in random-access memory (RAM). Those instructions, as well as the results of the processing, are often stored in permanent memory such as a hard drive or solid-state disk (SSD). The computer is typically operated via an input device such as a keyboard or mouse, and the results of the program may be communicated via a monitor or printer.
