Memory | MCQs

Explanation

ROM is a type of non-volatile memory that stores the basic input/output system (BIOS) and other firmware that controls the computer's hardware components. When a computer is powered on, the BIOS stored in ROM is executed to:

• 1. Initialize hardware components
• 2. Detect and configure peripherals
• 3. Load the operating system from storage devices

Explanation

ROM is a type of memory that contains permanent data that cannot be changed or written to.

It is used to store firmware or software that is permanently stored in the computer.

It is used to control the computer's basic functions.

Explanation

L3 cache is a level of CPU cache memory that is slower than L1 and L2, but still faster than main RAM.

It helps improve overall CPU performance by storing frequently accessed data shared across cores.

Explanation

Magnetic memory (like hard drives and magnetic tapes) is read-write, not read-only — data can be both read and modified.

It is also non-volatile, reliable, and relatively cheap for storing large amounts of data.

Explanation

L1 cache (Level 1 cache) is the fastest and smallest cache memory, integrated directly into the processor.

It stores frequently accessed data and instructions to speed up processing.

Explanation

ROM (Read-Only Memory) is non-volatile.

This meaning it retains data even when the power is turned off.

RAM is volatile.

Explanation

the Device having the largest storage capacity is Hard Disk.

hard disk has a capacity from 5 MB to 100 TB

while

The CD has a capacity of 700 MB

DVD has a capacity of 4.8 GB to 8.5 GB

Explanation

DRAM (Dynamic Random-Access Memory) is used for temporary storage while the computer is on.

Explanation

Transfer method:

This refers to the process of moving data between secondary memory (like hard drives or SSDs) and primary memory (RAM).

For example, when files are loaded from a hard drive into RAM, data transfer occurs.

Explanation

the memory of computers is measured in the terms of Bytes.

A memory unit is the amount of data that can be stored in the storage unit.

This storage capacity is expressed in terms of Bytes.
