Within this unit i am going to be talking about text editing. A text editor is a program used for editing text files. They are usually provided within the software packages themself or even with the operating system itself. When I am talking about plain text files you will most likely think I mean word documents. Well i don't. There is a difference between plain text files and word documents. A plain text file is something which is represented and edited by showing all of the characters as they are present in the file. Plain text files are usually used for programming and configuration rather than a documentation for example.. detailed instructions and user guides. Documents made within a word processor are usually control characters. By this i mean it enable's and functions different ways a font is shown such as bold, italic, underline, tables etc. These and other common formatting symbols where they were once only used with desktop publishing software but now they are used in the simplest word processor. Word processing software usually edit's a plain text file and then save's it back to the old plain text file but you must tell word that this is what you want to happen or else it would just save as a document. It is important that you specify the type of saved file you want, just like you would with HTML and configuration. Before text editors existed computer text was punched into punched cards with keypunch machines. The first ever text editors were known as (line editors). They didn't provide a window or screen display. To minimise typing they often had very short commands. Amongst that was a command to print selected sections of the file on the typewriter. When computer's with video screens became available screen editor's became more commonly used. There are different types of text editors, some are quite small and simple where as others are bigger and much more complex to use. Unit operating systems use the VI editor and Microsoft systems use the notepad which I'm sure which i am sure you use reasonably often, its very easy to use.
Now i will talk about proof reading. It is very important to proof read your work. Yes your computer may have spell checker but it doesn't always correct the mistakes you will have made. The computer may be in a different language style so when your typing and its on U.S on word then it would replace colour with color. Even though they mean the same thing it won't look good if you're doing work for an english company and give them work that you have produced with American grammer used. So when you proof read you must check you work carefully. You must do this to make sure that it makes sense and that whoever you are writing to will be able to understand the document. If you hand work to a client and it doesn't make sense or the punctuation is really bad then they will be thinking why have I hired such a rookie when he isn't a professional. They would then write reviews about you which wouldn't look good and people therefore wouldn't hire you.
