Ascii
Ascii stands for ‘American Standard Code for Information Interchange’
The standard Ascii character set uses just 7 bits for each character. However some larger sets use 8 bits, which gives them 128 additional characters. These extra characters are used to represent non-English characters.
- A character code uses 1 byte for each character, for each character cam have 255 different characters and symbols.
Unicode
Unicode uses 16 or 32 bits and is usually shown in hexadecimal. Unicode can have larger character sets as it uses more bits to represent each character. This extra character sets allows for sets from other languages to be used.
- Everything in Unicode has a much larger file size and would take longer to transfer than something in Ascii.

WWW – Some good explanation of what ASCII and Unicode is
EBI – Would be good to have some more discussion which you would use in which circumstances?
