Who invented ascii?

Bob Bemer developed the Ascii coding system to standardise the way computers represent letters, numbers, punctuation marks and some control codes. He also introduced the backslash and escape key to the world of computers and was one of the first to warn about the dangers of the millennium bug.

What is the difference between utf8 and Ascii?

UTF-8 is named for how it uses a minimum of 8 bits (or 1 byte) to store the unicode code-points. Remember that it can still use more bits, but does so only if it needs to. This also means UTF-16 is NO longer backwards compatible with ASCII. Remember ASCII only used 1 byte or 8 bits.

What is the ascii of 1?

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. … This mean that the 8-bit has been converted to a 7-bit characters, which adds extra bytes to encode them.
