Have you heard of the term ASCII?
Every bit of data a computer process has to be converted into something that is understandable to humans which makes sense and can be used. It could be your text document, image, or video.
But what you may not realize is that those text documents, images, and videos – anything, really starts as numbers; the only thing that computers understand. 1’s and 0’s (binary) are the computer data and ASCII is a system that maps data/numbers into a computer’s memory as text.
ASCII stands for American Standard Code for Information Interchange and ASCII assigns letters and characters to the 256 slots available in 8-bit code. For example ‘A’ is represented as 01000001.
