Mod 7 Web and Email Viruses
Viruses:
Viruses are programs that are written by people with the intent of damaging
your system. They are hidden within files and may be present in any
file that you download from the Internet. The simple solution is to
install an anti-virus program on your computer. An anti-virus program
will examine all new files that you download for potential viruses and
if it finds one will either alert you to the danger or remove the virus.
As new viruses are always emerging, it is important that you use an
up to date virus checker and that you keep it up to date!
Web Servers:
Think of using the WWW in the same way you would think of a book. There
are people who write and publish books and then there are the people
who read the books.You use your computer,modem and web browser to access
the books,or web sites.
A WWW server is just a computer not that different from the one you may have at home, just bigger and faster,it is a store for web pages which can be accessed by your browser.There are many such servers,each with their own address to enable them to be accessed by the browser.They must be up and running 24hrs a day so that the web pages stored are always available for viewing.There are numerous companies who will allow you to rent space on their WWW servers. You can send your information to this rented space and once there it is available for all to see.The term Web publishing simply means that you have your own WWW server (or space rented on somebody else's computer) and you publish data on it. Many individuals use this rented server space concept, where as larger organizations will maintain their own, separate WWW servers.
