Total Questions: 50

1. What is the full form of PROM? [S.S.C. Online CHSL (T-I) 13.10.2020 (Shift-I)]

Correct Answer: (c) Programmable read-only memory
Solution:

The full form of PROM is Programmable Read-Only Memory.

It is a type of non-volatile memory that can be programmed with data after it has been manufactured. Once the data is written onto a PROM chip, it becomes permanent and cannot be erased or altered.

2. ROM in computer science stands for? [S.S.C. Online CHSL (T-I) 18.01.2017 (Shift-I)]

Correct Answer: (c) Read Only Memory
Solution:

ROM in computer science stands for Read-Only Memory.
It is a type of non-volatile memory where data is permanently stored and can only be read, not easily written to or modified. This characteristic makes it ideal for storing crucial information that the computer needs to boot up and perform basic functions, such as the BIOS (Basic Input/Output System) or firmware for various hardware components. 

Non-Volatile:
 Unlike RAM (Random Access Memory), ROM retains its data even when the power is turned off. 

Read-Only:
 Under normal operating conditions, the data stored in ROM cannot be altered by the user. This ensures the integrity of critical system software. 

Permanent Storage:
The data is typically written onto the ROM chip during the manufacturing process.
