Word Processors • History – Compare modern word processors with old typewriter machines • With typewriters, making changes was very tedious (requires page rewriting) • With modern word processors, you can easily add font styles (bold/italic/. . ), different font types (Arial/Times Romans/…), colors, margins, tables, columns, etc. 9/20/2021 TU 170 Learning Online( Prepared By: M.

Word Processors (Cont. ) • Teletype machine – These are automatic typewriter machines connected to computers – Computers feed a string of codes (characters, numbers or symbols like spaces, CR (Carriage Return) and LF (Line Feed)) into the teletype machine – Such code is called the ASCII code, which stands for American Standard Code for Information Interchange 9/20/2021 TU 170 Learning Online( Prepared By: M.

Word Processors (Cont. ) • Modern word processors – They treat text as string of code, but with more codes corresponding to features such as (bold, italic, margins, etc. ) • You cannot see these codes, you only see the effects of these codes. • You can see the codes corresponding to some simple text such as the spaces, returns and tabs. – The problem of incompatible files • Older versions cannot read files created by newer versions, because this requires first converting the codes corresponding to the new features. This process is not always successful – Solutions: • Save file in Rich Text Format. rtf • Save file in text format. txt 9/20/2021 TU 170 Learning Online( Prepared By: M. Hussein Y.
