The latter are designed to handle many kinds of file formats. If printing the documents you create is all you do, then your word processor's native format is the only one you will use and there is no need to worry about saving in other formats. However, more computer users now enjoy the benefits of electronic mail. When using this option, you can not store information about eg text size or fonts. The advantage, however, is that when you log on to an e-mail service, you can upload your already completed mail, saving money on connection time.
Many people now have pagers that they keep on their belt and which display messages on tiny screens.
Those messages come from people who call up an ordinary telephone number and leave a message orally at the paging centre. The operator who receives the call types the message into a computer which transmits the message via radio waves to a pager's screen. Meanwhile, a person with a pager may also have an electronic mailbox filling with e-mail. Link Telecommunications likely will soon offer a service through which you can receive notification of arriving e-mail via the pager on your belt. The HP 95LX can receive much longer messages and manipulate them in clever, automatic ways.
