What is the different between Bit, Byte, Nibble, Word, Kilobyte(KB), Megabyte(MB), Gigabyte(GB), Terabytes(TB).

Bit: A bit is the smallest unit if information that can be stored in a computer. Bits in computer are grouped to form a lager unit of information
Byte: A byte is a combination of eight bits. Eight bits represent a character and is called a byte.

Nibble: A nibble is a combination of four bits, in other words a nibble is half a byte.
Word: a word is a combination of 16 bits, 32 bits or 64 bits depending on the computer. 16 is known as quad word.
Kilobyte (kb): A kilobyte has a memory unit of 1024 (2**10)
Megabyte: a megabyte has a memory unit if 1,048,576 (2
**20). This is approximately 1 million bytes.
Gigabytes (gb): A gigabyte has a memory unit of 1,073,741,824 (2**30). This approximately billion bytes.
Terabytes: a terabyte has a memory unit of (2**40). This is approximately 1 trillion bytes.
Note:
1024 byte = 1 kilobyte (1kb)
1024 kilobytes = 1 megabytes (1mb)
1024 megabyte = 1 gigabytes (1 Gb)
1024 gigabytes =1 terabyte (1tb)
