Detailed explanation-1: -ASCII is a 7-bit code, representing 128 different characters. When an ASCII character is stored in a byte the most significant bit is always zero.
Detailed explanation-2: -7-bit encoding is a reference to the Ascii character set-pronounced “Askey” and standing for “American Standard Code for Information Interchange”-which is a mapping of English alphabet characters, numbers and symbols to 7-bit numerical values in the range 0 to 127.
Detailed explanation-3: -ASCII. ASCII was originally developed for basic computers and printers. It uses a 7-bit code to represent characters. As more computers began to work with 8-bit groups of data, ASCII was written as 8 bits.
Detailed explanation-4: -The standard ASCII character set is only 7 bits, and characters are represented as 8-bit bytes with the most significant bit set to 0. Modern computers almost universally use 8-bit bytes, and the extended ASCII character set includes 127 more 8-bit characters, where the most significant bit is set to 1.
