Increased RAM in computer systems means..

More programs can run simultaneously

Changes to files will not need to be saved

Virtual memory can run simultaneously

The characteristics of RAM are it is .....

Temporary, volatile, expandable and you can write to it.

Permanent, non-volatile, not expandable and you can't write to it

Why is ROM need in a computer system?

It stores the 'bootstrap loader' which is needed to load the operating system.Without it, the computer wouldn't turn on.

It stores the data of the operating system and programs that are currently running, for access by the CPU.

Why is Virtual Memory needed in a computer system?

When several programs run at the same time, the RAM can be full. Instead of closing programs the Operating system uses virtual memory to store some data.

It is used as a fast type of memory for programs currently in use to speed up the performance of a computer.

Where is data stored when it is Virtual Memory?

It is stored on a area of a secondary storage device e.g. hard disk drive.

It is stored in an optical drive e.g. CD.

What is a disadvantage of Virtual Memory?

Read/Write speed of a hard disk drive is slower than RAM. If the computer has to rely on this, the system is much slower.

Read/Write speeds of a hard drive are faster than RAM, meaning the system is much faster.

In terms of computer memory, what is meant by the term 'volatile'?

It loses its contents when power is cut

It retains its content when power is cut

It is not stable and should not be used

Which statement best describes ROM?

A flash memory chip that contains a small amount of non-volatile memory

A memory store containing a large amount of volatile memory

A register within the CPU responsible for storing memory addresses

A memory store containing a small amount of volatile memory

What is usually held in the contents of RAM?

Operating System and currently running programs

BIOS and Boot sequence needed to start the computer

Software programs stored within the computer

Recently executed instructions in case they are needed again

What is stored in Read Only Memory (ROM)?

BIOS and boot sequence (the computer's initial start-up process)

Operating system and currently running programs

Found in the computer's BIOS, what actually is the 'bootstrap'?

The program which takes the computer through steps that lead up to the loading of the operating system (OS)

The program responsible for loading the drives for peripheral devices like the keyboard and mouse

T he computer's initial start-up process

The device used to attach the ROM to the computer's motherboard

Which of these items are NOT stored in RAM

Instructions to load up the computer

Which transfer is faster

data between the cache and the CPU

data between the hard drive and CPU

Why do a lot of devices use flash memory

It's almost unbreakable due to no moving parts

It is the fastest sort of memory/storage you can get

It is the cheapest form of memory/storage

It needs zero power to write to/read from
