Memory | MCQs

Explanation

Memory Swapping is a memory management technique that involves moving some of the contents of RAM to a disk space called a swap space or swap file.

Explanation

computer memory capacity is expressed in multiples of a power of two.

it is measured in megabytes (MB) and gigabytes (GB).

A medium-sized novel contains about 1 MB of information.

1 MB is 1,024 kilobytes, or 1,048,576 (1024x1024) bytes, not one million bytes.

Similarly, one 1 GB is 1,024 MB, or 1,073,741,824 (1024x1024x1024) bytes.

Explanation

The abbreviation “MB” stands for “megabyte,” a unit of computer storage.

Unit                 Description

Megabyte 1024 kilobytes

Gigabyte         1024 megabytes

Terabyte         1024 gigabytes

Petabyte         1024 terabytes

2 Secondary memory (hard drive,CD,etc.)

Explanation

Explanation

A computer's short-term memory is called: RAM (Random Access Memory).

RAM is used to temporarily store data while a computer is running, allowing quick access to information.

Explanation

 DRAM memories need a refresh.

Dynamic Random Access Memory (DRAM).

DRAM must be refreshed many times per second to store information, otherwise, it will lose what it is holding.

DRAM is the most common type of memory in use today.
