- Hostname vs. IP - address. A host name is a combination of the name of your machine and a domain name (e.g. machinename.domain.com). The purpose of a host name is readability - it's much easier to remember than an IP address. All hostnames resolve to IP addresses, so in many instances they are talked about like they are interchangeable.

- File infector viruses are those that infect other files or programs on your system. They operate in a number of ways. Once the original 'host' program is run, the virus can stay resident or 'live' inside your systems memory (RAM) and infect programs as they are opened, or they can lay dormant inside another program.ach time that program is run, the virus will infect another program or file. A second, more complex file infector is one that doesn't alter the program itself, but alters the route a computer takes to open a file. In this way, the virus is executed first, and then the original program is opened.
