Basic Unit : bit

Bit : A Bit is a value of either a 0 or 1.

Byte : 1 Byte = 8 Bits

8 Bits = 1 Byte (B)

1024 B = 1 Kilobyte (KB)
1024 KB = 1 Megabyte (MB)
1024 MB = 1 Gigabyte (GB)
1024 GB = 1 Terabyte (MB)
1024 TB = 1 PetaByte (PB)
1024 PB = 1 ExaByte (EB)
1024 EB = 1 ZettaByte (ZB)

Bit is denoted by small letter 'b' and Byte is denoted by capital letter 'B'

Kilobyte (KB) : 1 KB = 8,192 Bits ,

Example :
2 Mbps means 2 Megabits per second and 2 MBps means 2 Megabytes per second
i.e., 2 Mbps = 2048 Kbps = 256 KBps
