It is faster than dynamic RAM.

All of these are true.

Which of the following statement is false about dynamic RAM?

DRAM needs a continuously refreshed memory to store data.

It is slower than SRAM.

EPROM is used for

erasing the data of ROM

reconstructing data of ROM

duplicating ROM

erasing and reconstructing data of ROM

EPROM is generally erased by

infrared rays

ultraviolet rays

Electromagnetic signal

12V electrical pulse

Virtual memory is an

extremely large secondary memory

illusion of an extremely large memory

multitasking

multiprocessing

virtual storage

multiprogramming

USB stands for

Uniform service bus

Universal serial bus

Universal serial buffer

Universal sector bus

The memory that cannot be accessed directly by processor (CPU) is

internal memory

external memory

cache memory

system memory

In which storage medium, we can store the maximum amount of data

Magnetic storage

Optical storage

Solid data storage

Storage capacity

Which of the following memories has the fastest (or shortest) access time?

RAM

ROM

Cache memory

Magnetic core memory

Why do we use cache memory between CPU and main memory?

to increase the internal memory of computer system

to reduce the memory access and cycle time

to store data and programs that can be executed within a short period of time

both a and d

The advantages of using secondary memory storage in a personal computer are

very high storage capacity

permanent storage (non-volatile)

stores data that are not currently being used by CPU

All of these

Hard disk can be formatted at the time of

RAM

Booting

disk reader

None of these

Which of the following memory storage is slow?

Magnetic disc

RAM

Hard disk

Optical disk

The key feature of dynamic RAM is

it is less expensive and cheaper than static RAM

it is faster than SRAM

it is bigger in size than SRAM

it requires less power than static RAM

Higher the RAM of computer, the faster its processing speed. Since it eliminates

need for external memory

need for ROM

need for cache memory

All of these

Which of the following is the feature of SRAM?

It is faster than DRAM

It is bigger in size and more expensive than DRAM

it requires less power consumption

All of these
