Representing Information as bit patterns

2. Representing Text:
The American National Standards Institute (ANSI) adapted the American Standard Code for Information Interchange (ASCII)
This code uses 7 bits to represent the alphabets (a-z & A-Z) and numbers from 0 to 9 and punctuation symbols.
Ex: . o l e H

3. Unicode: This code uses 16 bits represents each symbols.
Unicode consists of different bit patterns enough to allow text written in such languages
A file containing a long sequence of symbols encoded using ASCII or Unicode is often called a text file

4. The difference between word processors and text file as follows:
Use word application
Use text editor 1
Contains numbers proprietary codes representing changes in fonts, alignment information, …etc
Contains only character-by-
character encoding of text 2
Use proprietary code rather than the ASCII or Unicode
Use ASCII or Unicode 3
