Computer Memory | MCQs

Explanation

Byte is made up of array of bits.

Explanation

Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions.

Explanation

The hard disk was invented on September 13, 1956, by an IBM team led by Rey Johnson

The commercial usage of hard disk drives (HDD) began in 1957

Rey Johnson (considered as “father” of the disk drive).

Explanation

RAM and ROM difference

Explanation

Explanation

Primary storage, also known as main storage or memory.

It is the area in a computer in which data is stored for quick access by the computer's processor.

The terms random access memory (RAM) and memory are often as synonyms for primary or main storage.

Explanation

Explanation

RAM, or Random Access Memory, is a type of computer memory that is used to store data or programs that the CPU is currently using.

 It's a temporary storage space that is cleared when the computer is turned off.   

Explanation

Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell,

usually consisting of a tiny capacitor and a transistor,

both typically based on metal-oxide-semiconductor (MOS) technology.

Explanation

The exact number of bytes contained in the main memory is 960 × 1024.
