Data Files on Computers Text Files (ASCII) Files that can be created by typing on the keyboard while using a text editor such as notepad or TextEdit. Binary Files Files that cannot be created as above. Note however that using a keyboard does not always result in a text file. For example, Word (or most word processing programs) store files as binary.

Storage of Text Files Normally stored in ASCII which uses 8 bits (one byte) for each keystroke. Can also be stored in unicode which uses 16 bits (two bytes) for each keystroke.

Text on Web Pages There is a meta tag in the header of a Web page which tells the browser which character set to use when displaying a page. shows that the page is using UTF-8 as the character set (a unicode set). Other common character sets are: charset = ISO (English) charset = ISO 2022-CN (Chinese) charset = ISO 2022-JP (Japanese)
