The following links may be very useful to you. As a technician using Microsoft products, the first link has proven to be invaluable in my work. From product updates, to the latest news and information from the developers at Microsoft, this site is essential. Cnet is another very useful site that gives you free and shareware software. The link to the NCSA takes you to a page that tells you all you ever wanted to know about HTML and designing a Web page. The high tech definitions and ZDWebopedia links are very interesting and gives you more insight into definitions and topics relating to computers than you probably ever wanted to know :-)
Other non-MIS sites that might be of interest to you:
Microsoft.com
This site is a must for technicians and analysts who use Microsoft products.
