I presently use a cable modem to connect on to the internet and I have a PC. In October i will be getting a new iMac and I just want to make sure that my cable modem will work with the iMac? What port would I plug the cable into on the back of the iMac? Also I have high-speed internet not dsl.....

Yes, no problem. Networking is universally compatible. SHould just need to plug into the iMac's ethernet port and be good to go.

It doesn't matter what Internet service you have (beyond dial-up)...it all gets converted into standard Ethernet. That's exactly what the models are for, because no computer has the built-in capability to understand (or physically accept) a data stream over a coaxial cable or DSL line. The modem translates whatever means the ISP uses to get the Internet to you into the Ethernet networking standard so any computer can use it.

Also, if you don't have one, you should probably think about getting a router. It's not a good idea to have a computer hooked directly into a modem; you're open to the entire Internet that way.

Why is that i thought Macs were safer than a PC? Also all i have now is a modem in use not a router......

All routers -- wireless or wired -- act as a "hardware firewall" between your computer and the internet. Routers keep track of which computers request what data, and send the responses back to that computer only. So if any data comes from "out there" that you didn't specifically request (even if you only have a single computer connected) it will be blocked and will not reach your computer. OSX has a software firewall installed but a router is cheap, cheap insurance against all sorts of unwanted intrusions.

Here you have some online intrusion tests that can tell you if ports to your system are open or closed or invisible (stealth) from outside. The site is rather windows-orientated but for some sketchy information it should be good enough.
