COMMUNICATION CODES
Smoke signals, Morse code and semaphore are some of the communication codes used by people in the early days. In the information digital era, people send information via electronic devices such as through the computers. Computers use binary codes to communicate. One of the widely used binary codes is the American Standard Code for Information Interchange (ASCII).
HISTORY OF CHARACTER CODES
Before people used binary codes such as ASCII to communicate via computers, character codes were widely used as a medium of communication. Let’s look at some of the character codes used prior to the use of ASCII.
WHAT IS ASCII?
ASCII pronounced as "ask-key" stands for the American Standard Code for Information Interchange and was proposed by ASA (American Standard Association) in 963 and was finalised in 1968.ASCII is a standard of 7-bit code used to represent characters, which include letters, numbers and punctuation marks.
IBM and Apple expanded the amount of space reserved for the character codes to 8-bits, equivalent to 1 byte.
