Understanding Virtual Memory

The video explains the concept of virtual memory in computers. It starts by discussing the role of RAM in storing programs and data for the CPU. It highlights the limitations of RAM size and the advantage of hard disk storage. The video then introduces virtual memory as a solution for when RAM is insufficient, allowing programs to be swapped between RAM and the hard disk. This creates the illusion of more memory than physically available. The video concludes with a recap of how virtual memory operates, emphasizing its importance in modern computing.

What is the primary reason for the need for virtual memory in computers?

• To increase the speed of the CPU

• To reduce the cost of hard disk space

• To allow more programs to run simultaneously

• To improve the quality of graphics

Why is hard disk space considered cheaper than RAM?

• Because it is faster

• Because it is more durable

• Because it is less expensive byte-for-byte

• Because it is easier to install

What is the role of the bootstrap program when a computer is turned on?

• To start the graphics card

• To connect to the internet

• To check for viruses

• To load the operating system into RAM

What happens when a computer runs out of RAM?

• The CPU stops executing instructions

• The operating system crashes

• Instructions are transferred to virtual memory

• The computer shuts down

How does virtual memory create the impression of more memory?

• By using cloud storage

• By increasing the CPU speed

• By swapping programs between RAM and hard disk

• By compressing data

Where is virtual memory located?

• In the cloud

• On the hard disk

• On the CPU

• In the graphics card

What happens to programs not currently being executed in RAM?

• They are transferred to virtual memory

• They are executed in the background

• They are compressed

• They are deleted
