What is ASCII ?

Short for American Standard Code for Information Interexchange, ASCII is a standard that assigns letters, numbers, and different characters in the 256 places accessible in the 8-bit code. The ASCII decimal (Dec) number is made from binary, which is the language computer understands. 

ASCII was first evolved and distributed in 1963 by the X3 board of committee, a part of the ASA (American Standards Association). The ASCII standard was first distributed as ASA X3.4-1963, with ten amendments of the standard being distributed somewhere in the range of 1967 and 1986.
