• BIT - Binary digit which can be ‘0’ or ‘1’.
• Nibble is a collection of 4 bits (Binary digits)
• A collection of 8 bits is called Byte.
• Word length refers to the number of bits processed by a Computer’s CPU.
• For example, a word length can have 8 bits, 16 bits, 32 bits and 64 bits (Present day Computers use 32 bits or 64 bits)

The speed of a computer depends on the number of bits it can process at once.

For example, a 64- bit computer can process 64-bit numbers in one operation, while a 32-bit computer break 64-bit numbers down into smaller pieces, making it slower.
