Detailed explanation-1: -The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.
Detailed explanation-2: -Common binary number lengths From there, a group of 4 bits is called a nibble, and 8-bits makes a byte.
Detailed explanation-3: -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. A disk that can hold 1.44 megabytes, for example, is capable of storing approximately 1.4 million characters, or about 3, 000 pages of information.
Detailed explanation-4: -A group of 8 bits is called a Byte.
Detailed explanation-5: -Two factors were important: Having units which are powers of two (2, 4, 8, 16, 32 etc.) is more convenient when designing digital systems. 8-bit is enough to store a single character in the ASCII character set (with room to spare for extending the character set to support say Cyrillic).
