Detailed explanation-1: -Data storage capacities are measured in bytes, where each byte is actually a pattern of 8 bits. Each bit is represented by either a 1 or a 0 (on or off), also known as binary code. 1 byte can hold 1 character of data, e.g. “p” is 1 byte.
Detailed explanation-2: -The answer to this question is (a) True. Explanation: In a single byte of data, a single ASCII character like “h” can be stored. A kilobyte (KB) is 1, 024 bytes, not the 1, 000 bytes that one may believe, because computers use binary (base two) math instead of a decimal (base ten) system.
Detailed explanation-3: -While bytes are measured in bit multiples, computer storage is typically measured in byte multiples. In many computer architectures, a byte is the smallest addressable unit of memory. For example, an 820 megabyte (MB) hard drive holds a nominal 820 million bytes of data.
