Computers have become so pervasive in our society that just about everybody uses them in some way or another. Electronic communication keeps family members in touch with each other across continents. Businesses use email, web conferences, and VoIP (internet telephony) to streamline their trading activities. Shoppers use the Internet to find bargains. This electronic lifestyle generates a constant stream of data. As one might expect there will be very negative consequences if this data is lost due to a crash, computer virus, or physical loss of your computer through fire or theft. Everything on your computer - from financial records to family digital photographs - is vulnerable to loss.

Joomla is  "open source" software developed by volunteers around the world.  "Open Source" software means that you are allowed to view (and change) the actual code that drives the program.  Joomla is free software - free in terms of financial cost and free in terms of being able to view the computer code.  It is used by prestigious companies around the world and has won several awards. 

By now just about everybody who uses a computer is aware of how Viruses, Trojans, Spyware, and other malicious software can interfere with their systems, cause data loss, or even take control of your computer. Using a good Antivirus software package coupled with a firewall can go a long way in protecting your system. However even the very best security systems can be overcome. My computer science lecturer in university once commented that the only way to secure data on a computer was to turn it off, lock the PC in a safe, and then put the safe in a very dark basement where nobody can find it. Security breaches are nearly inevitable, especially if you don't keep your operating system up to date or don't use antivirus software!
