TechDocUSA.com 12 DSL or Cable Modem This is your Broadband, ISP, Cable provider or Satellite dish hookup Essentially, this is your high speed bandwidth connectivity to the internet. If you have dial-up (phone line), then you will not likely have a router or physical firewall. You will depend on software protection.
TechDocUSA.com 13 Router Splits up a single user on a DSL/Cable modem to into multiple users. Often serves as a firewall device. A commercial router, like a CISCO, provides many more capabilities.
TechDocUSA.com 14 Firewall A firewall has several uses. Primarily it is used to stop intrusion. It can be a software program on your pc or it can be a hardware device. Hardware firewalls protect more effectively than most of the low end software packages.
TechDocUSA.com 15 Software Firewalls Norton internet security (virus & firewall) (popular & suitable) McAfee (good web site) Trendmicro (great site too) BlackIce (technical, but also good) ZoneAlarm Pro4, or free (ZAP4: my personal choice for most protection and detailed control).
TechDocUSA.com 16 A worm is a program that can run independently and can propagate a fully working version of itself to other machines. It is derived from the word tapeworm, a parasitic organism that lives inside a host and uses its resources to maintain itself. A virus is a piece of code that adds itself to other programs, including operating systems. It cannot run independentlyit requires that its host program be run to activate it. As such, it has an analog to biological viruses those viruses are not considered alive in the usual sense; instead, they invade host cells and corrupt them, causing them to produce new viruses.
