FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -On almost all modern computers, a byte is equal to 8 bits. Large amounts of memory are indicated in terms of kilobytes, megabytes, and gigabytes.

Detailed explanation-2: -A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits).

Detailed explanation-3: -A four-bit quantity is often called a nibble, also nybble, which is conveniently represented by a single hexadecimal digit. The term octet is used to unambiguously specify a size of eight bits. It is used extensively in protocol definitions.

Detailed explanation-4: -Since one byte is made up of eight bits, this difference can be significant.
