Question 32

There are two types of internal memory in computer system. Name and discuss them.

Answer

The two types of internal memory in computer system are as follows:

  1. Read Only Memory (ROM) — In this memory, information once stored remains fixed i.e., it cannot be changed. So, ROM can only be read and used. It cannot be changed or written onto.
    Generally, ROM contains a set of start-up instructions i.e., what to do when a computer is turned on. The contents of ROM remain stored even if power is turned off.

  2. Random Access Memory (RAM) — The internal memory that can be read from as well as written to is called RAM i.e., Random Access Memory. The random access memory (RAM) is volatile i.e., its contents are lost when power is turned off.
