FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Computer storage and memory is often measured in megabytes (MB) and gigabytes (GB). A medium-sized novel contains about 1 MB of information. 1 MB is 1, 024 kilobytes, or 1, 048, 576 (1024x1024) bytes, not one million bytes. Similarly, one 1 GB is 1, 024 MB, or 1, 073, 741, 824 (1024x1024x1024) bytes.

Detailed explanation-2: -This is because historically, 8 bits are needed to encode a single character of text. So when we measure the volume of information capable of being contained on, say, a hard drive, it makes sense to measure this as the total amount of memory available. In other words, the number of bytes.

Detailed explanation-3: -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-4: -A byte is the smallest unit of memory used in today’s computing. Bytes consist of eight bits, and a byte is used to encode a single number, letter, or symbol. Bytes’ use as such is a de facto international convention documented as ISO/IEC 2382-1:1993 by the International Organization for Standardization (ISO).
