Your computer is like any valuable asset, you have to protect
it from harm, deliberate and otherwise. A firewall can help
protect your computer from intruders. A
firewall
is software and/or hardware that protects computers from
intruders. As hardware, a firewall is often a router, and is
usually used for a network. If you have just one computer, a
software package that detects anyone trying to access your
computer will give your protection. You can protect your computer from power surges and outages by
using an uninterruptible power supply (UPS). Having anti-virus software on you computer alerts you if
you're about to let a virus into your system. The software
will usually give you options on quarantining or cleaning the
virus or deleting the whole file. Below are some sites you can visit to learn more about the
