Memory Management | MCQs

Explanation

Feature Virtual Memory

Location: On the hard drive or SSD

Speed: Slower (due to disk I/O operations)

Capacity: Larger, limited by disk space

Cost: Lower (cost of additional disk storage)

Explanation

In both C and C++ programming languages, the symbol used to access the value stored at a memory address (dereferencing a pointer) is the asterisk (*).

* and & are the operators used in pointers.

* gives us the value stored at a particular address

whereas “ & “ gives us the address of the variable

Explanation

Explanation

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

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.

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

Multitasking provides process and memory management services

Multitasking allows two or more tasks, jobs, or programs to run simultaneously.

Multitasking Most of today's popular operating systems offers multitasking services.

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.

Explanation

Yottabyte is the largest size of computer memory.

Terabyte is the largest measure of computer memory. The terabyte is a multiple of the unit byte for digital information.

The prefix tera represents the fourth power of 1000, and means 10¹² in the International System of Units, and therefore one terabyte is one trillion bytes.

Explanation

Computer RAM is essentially short term memory where data is stored as the processor needs it.
