Information- The is processed organized and structured data.

  

Bit-The binary digit which is represented in 0 and 1 form.

 

Nibble-The group of 4 bits is called nibble.

 

Byte-The group of 8 bits is called byte.

 

 

Kilobyte       KB       1000¹

Megabyte     MB      1000²

Gigabyte       GB      1000³

Terabyte       TB       1000⁴

Petabyte        PB      1000⁵

Exa byte        EB      1000⁶

Zetta byte     ZB       1000⁷

Yotta byte     YB      1000⁸

 

 

Kilo- means 1000

Mega- means 1000000

Giga- means 1000000000

Tera- means 1000000000000

Peta- means 1000000000000000

Exa- means 1000000000000000000

B 01000010

C 01000011

 

The advantages of memory unit-

 

(1)Software size-The memory unit tell how many size of software for example- 1MB or 1GB etc.

 

(2)Speed of computer- The speed of Random Access Memory(RAM) is depends on size of RAM.

 

(3)The size of RAM is deciding on memory unit for example MB or GB. The higher size of RAM is faster speed. When RAM Size is increase speed of computer is also increase.

 

(4)Internet speed- The internet speed is count on base of the memory unit for example Byte Per Second(BPS), Mega Byte Per Second (MBPS).

 

(5)Performance-The Memory speed help to know the performance of computer.

 

(6)Storage device-The storage device is also see their capacity on base of their memory unit for example CD 700MB, DVD 4 GB Hard disk 1TB etc.
