The real difference lies in the type of disc you use in the appropriate drive.

A CD-R disc usually has a capacity of 650 Megabytes and can be used for recording data (information) once. Nowadays, these discs allow you to keep adding data to the same disc until it is full. But you cannot re-record over these discs the way you can with an audio cassette or video cassette, for example.

To rewrite over previously recorded data, you need to use a CD-RW disc/drive. CD-RW stands for Compact Disc ReWritable. It can store a similar amount of data in total but this form of back up allows you to record data to the same disc again and again, which makes it much more useful for backing up data where you want to keep the latest version of a file and lose the previous version.

Staff sometimes need saving from themselves. A computer company, Surfcontrol, has produced two handy guides which you can download from its Website.

One is designed to help employees avoid making embarrassing (and sometimes job-threatening) email blunders at work. How To Use Email in the Workplace advises employees on the nuances of email use and provides tips on avoiding pitfalls.

With a recent survey showing that email has replaced telephone communication by 45 percent, the guide's "Email Commandments" are especially timely.

It tackles a range of common email ailments such as:

		using the "CC", "BCC" and "Reply All" buttons as political tools;
		emailing in anger and repenting at snail-mail pace;
		pressing the delete button and believing an email is gone for good;
		using email when you should be using the phone;
		assuming everyone shares your sense of humour;
		forgetting that UPPER-CASE EMAIL is SHOUTING; and
		explaining when it's :-( to :-) on email.

If you are involved in implementing an email policy, you should look at the employee guide's sister publication: How to Write an Email Acceptable Use Policy". This will help you formulate your document.

Most printers offer you the option of printing in draft or finished copy.

So, if you are planning to proof-read your article for Nephronline in hard copy before sending it in, you'll save money on your ink/toner by using the draft option. It will also save you time because draft versions print out faster than finished-copy versions.

Have a look at your print options, which you can usually access through:

		File at the top of the word-processing screen
		Printer Properties in the dropdown menu
		Page Setup in the side bar
		Options -- a button in the Setup menu

Exactly what your draft mode will be called depends on your printer manufacturer, but it usually has a fairly obvious -- if precious -- name.

You can restart Windows at any time without going through the Start to Shut Down to Restart route by simply simultaneous pressing: Ctrl+Alt+Delete twice.

This is called "soft reboot" by we old-fashioned computer users.

But remember you will lose any unsaved information.
