Is ASCII code 7-bit or 8-bit?

Question

My teacher told me ASCII is 8-bit character coding scheme. But it is defined only for 0-127 codes which means it can be fit into 7-bits. So can\'t it be argued that ASCII bi

Answer 1

The original ASCII code provided 128 different characters numbered 0 to 127. ASCII a 7-bit are synonymous, since the 8-bit byte is the common storage element, ASCII leaves room for 128 additional characters which are used for foreign languages and other symbols. But 7-bit code was original made before 8-bit code. ASCII stand for American Standard Code for Information Interchange In early internet mail systems, it only supported only 7-bit ASCII codes, this was because it then could execute programs and multimedia files over suck systems. These systems use 8 bits of the byte but then it must then be turned into a 7-bit format using coding methods such as MIME, UUcoding and BinHex. This mean that the 8-bit has been converted to a 7-bit characters, which adds extra bytes to encode them.
