Computer Memory | MCQs

Explanation

1 byte equals 8 bits.

Additional Information

Explanation

Cache memory is also called CPU memory.

Cache memory is the fastest.

It is located close to the CPU.

It temporarily stores frequently used data for quick access by the processor.

Explanation

In computer architecture, 8-bit integers or other data units are those that are 8 bits 

Unit of: digital information, data size

Unit system: unit derived from bit

Terabytes (TB)

Explanation

Non-volatile memory or is a type of computer memory that can retain stored information even after power is removed.

RAM is a volatile memory.

RAM: Random Access Memory.

ROM is a non-volatile memory.

ROM: Read Only Memory.

Explanation

• RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS).

• RAM is also known as read/write memory.

Explanation

The size of information in the computer is measured in Kilobytes (KB), Megabytes (MB), Gigabytes (GB), and Terabytes (TB).

1024 kilobytes (KB) is equal to 1 megabyte (MB).

One Megabyte (MB) = 1024 Kilobytes (KB

One Gigabyte (GB) =  1024 Megabytes MB

One Terabyte (TB)= 1024 gigabytes (GB).

Explanation

EEPROM Stand for Electrically erasable programmable read-only memory.

EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge.

EEPROM is similar to Flash Memory

Explanation

Primary memory devices are more expensive than secondary storage devices.

Secondary memory devices are less expensive when compared to primary memory devices.

Primary memory is also known as Main memory or internal memory.

Secondary memory is also known as External memory or Auxiliary memory.
