What is used for holding program instructions that can't be changed throughout the life of the computer?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ROM
-
ROM (Read-Only Memory) is used to store program instructions that cannot be altered during the computer’s lifetime.
-
It contains essential instructions like the bootloader that help start the computer.
-
Data stored in ROM is non-volatile, meaning it remains intact even when the computer is powered off.
-
ROM ensures that critical system instructions are permanently available and secure from accidental changes.
Explanation of Other Options:
-
Register is a small, fast storage location inside the CPU used temporarily during processing.
-
RAM (Random Access Memory) is volatile memory used to store data temporarily while programs run.
-
Cache is a smaller, faster type of volatile memory that stores frequently accessed data to speed up processing.
-
Only ROM is permanent and unchangeable during normal operation.
