Email and instant messaging (IM) are ways of sending text messages back and forth to other people on the internet. They seem very similar: in both, you compose a message, and when it’s ready, you send it; and when someone else sends something to you, you receive it on your device and can read it. But in practice, email and IM can be surprisingly different; each has its own rhythm, its own strengths and weaknesses, its own sociology, its own etiquette. Instant messaging is like using the telephone, whereas email is more like corresponding by letter. Which medium is more appropriate for which kinds of relationships and communications? Which medium is more stressful to use? Which takes more time? Which is more convenient for you? Which one is more useful for getting real work done? Which medium would you use if you knew that whatever you wrote was eventually going to be published in a book? If you were restricted to using only one of these communications methods, which would it be?
The goal in formatting is to make the content easier to read and interpret. Suppose you have a worksheet where the content is overflowing onto several pages, describe at least three (3) steps or ways you would take to format and optimize the document for printing.
