Question

question 8 of 10
what is rom?

a. volatile memory that is frequently used in portable memory sticks
and modems

b. compression memory that stores data on remote servers and is
accessed via the internet

c. memory that stores data dynamically, requiring data to be
constantly refreshed

d. permanent memory that is directly accessible by the cpu and
cannot be lost when the computer is powered off

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Volatile memory loses data when power is off, but ROM is non - volatile. Also, portable memory sticks (like USB drives) and modems don't use ROM in this way. So A is incorrect.
• Option B: ROM is not compression memory and does not store data on remote servers (that's cloud storage - like concepts). So B is incorrect.
• Option C: Memory that needs constant refreshing is DRAM (Dynamic RAM), not ROM. ROM is read - only and non - volatile, with static data. So C is incorrect.
• Option D: ROM (Read - Only Memory) is permanent memory. It is directly accessible by the CPU, and the data in it is retained even when the computer is powered off. This matches the definition of ROM.

Answer:

D. Permanent memory that is directly accessible by the CPU and cannot be lost when the computer is powered off
