Question

discuss various storage units.

Answer 1

Bit
Byte- Group of 8 bit
1 Kilobyte (KB)=1024 Byte
1 GIGABYTE(MB)=1024KB
1 Gigabyte (GB)=1024MB
1 Terabyte (TB)=1024 GB

Answer 2

Bit is the smallest storage unit in which you can store either 1 and 0
Btye = 8 Bits
1 KB(KiloByte)        = 1024Byte
1 MB(Megabyte)     = 1024KB
1 GB(Gigabye)       = 1024MB
1 TB(Terabyte)       = 1024GB
1 PB(Petabyte)       = 1024TB
1 EB(Exabyte)        = 1024PB
1 ZB(Zettabyte)      =1024EB
1 YT(Yotabyte)        =1024ZB

The largest unit is not Yottabye.
The largest unit is Yobibyte 
1 Yobibyte = 1.208 Yottabyte
