Volatile Vs Non-Volatile Memory

easy
Computer Science

Which is a volatile memory?

A
ROM
B
BIOS
C
PROM
D
RAM
Explanation and memory cue

RAM (Random Access Memory) is volatile memory because it loses its data when power is turned off, unlike ROM, BIOS, and PROM which are non-volatile.

Practice MCQ

Medium
Computer Science

Which of the following is a way to access secondary memory?

A
Density method
B
Transfer method
C
Action method
D
Random Access Memory
Explanation and memory cue

Secondary memory is accessed through transfer methods that move data between storage devices and the computer system. Random Access Memory (RAM) is a type of primary memory, not a method for accessing secondary storage.

Cache Function

easy
Computer Science

Which acts as a buffer between the CPU and the main memory?

A
Cache memory
B
Buffer stock RAM
C
RAM
D
ROM
Explanation and memory cue

Cache memory acts as a buffer between the CPU and main memory by storing frequently accessed data and instructions, thereby reducing the time the CPU takes to access data from the slower main memory.

Data Storage Unit Order

easy
Computer Science

What comes after Exabyte in terms of increasing size?

A
Terabyte
B
Petabyte
C
Zettabyte
D
Yottabyte
Explanation and memory cue

After Exabyte, the next larger data storage unit is Zettabyte, followed by Yottabyte. Terabyte and Petabyte are smaller units than Exabyte.

Cache Purpose

easy
Computer Science

What is the purpose of cache memory in the CPU?

A
To store permanent data
B
To store frequently accessed data
C
To extend available memory
D
To store data in use by operating system
Explanation and memory cue

Cache memory is used to store frequently accessed data and instructions to speed up processing by reducing the time the CPU needs to fetch data from the main memory.

Practice MCQ

Computer Science

The primary function of a register in the CPU is ____?

A
To store data temporarily
B
To process instructions
C
To store program instructions
D
To store files
Explanation and memory cue

Registers in a CPU are small storage locations used to temporarily hold data and instructions that the CPU needs immediate access to during processing. This temporary storage enables faster data access compared to main memory.

Cache Placement

easy
Computer Science

Cache memory acts between ____:

A
CPU and Hard Disk
B
RAM and ROM
C
CPU and RAM
D
All of these
Explanation and memory cue

Cache memory is a small, fast memory located between the CPU and RAM to speed up data access by storing frequently used data and instructions close to the CPU.

Main Memory Terminology

easy
Computer Science

Another term for main memory is ____:

A
RAM
B
Cache
C
Hard Disk
D
None of these
Explanation and memory cue

Main memory is commonly referred to as RAM (Random Access Memory), which is the primary memory used by a computer to store data temporarily while it is running. Cache and hard disk are different types of memory/storage and do not refer to main memory.

Role Of Cpu Registers

easy
Computer Science

What is the main purpose of registers inside the CPU?

A
To store frequently accessed data
B
To store data being processed by the CPU
C
To store permanent data
D
To store data for virtual memory
Explanation and memory cue

Registers inside the CPU temporarily hold data and instructions that the CPU is currently processing, enabling fast access and manipulation during execution. This is their main purpose, distinguishing them from other storage types like cache or RAM.

Memory Hierarchy

easy
Computer Science

Which of the following is the smallest and fastest memory in the CPU?

A
Cache Memory
B
Register
C
Main Memory (RAM)
D
ROM
Explanation and memory cue

Registers are the smallest and fastest type of memory located inside the CPU, used to hold data and instructions that the CPU is currently processing. Cache memory is larger but slower than registers, while main memory (RAM) and ROM are much larger and slower.
