Binary code

Binary code is the most basic concept in modern computing, it can be used to represent many things. It is mainly a way of counting and expressing numerical quantities however it can also represent switches that are on or off. Zeroes and ones are the basic elements of binary code. Binary numbers are most useful in working with computers as they are made up of collections of on/off switches. "Binary numbers are useful in working with computers because computers are made up of collections of on/of switches. "An on/off switch can be represented by the digit zero ("0") if it is off or by the digit one ("1") if it is on" (Dilligan, 1988: 45).

Within computers there are millons of switches and the "0" or "1" notation of binary code gives a simple abbreviation to describe the state of a switch or sequence of switches in a computer.

ASCII

The American Standard Code for Information Interchange (ASCII) is a character-encoding scheme that is originally based on the English alphabet that encodes 128 specified characters, it encodes:

- the numbers from 0 – 9
- the letters a - z (lowercase)
- the letters A – Z (uppercase)
- basic punctuation, symbols
- control codes originated with Teletype machines
- a blank space – into the 7 –bit integers

ASCII codes represent text in computers, communications equipment and other devices that use text. It is developed from telegraphic codes where it was first used as a seven-bit teleprinter code that was promoted by Bell data services.
