    Okay so I'm doing quite a bit of stuff and have a little lag (4GB of RAM right now).

    What is Wired/Active/Inactive/Free RAM?
    I ordered another (2x2GB) of RAM which should be more than enough for how I use my iMac...but I was just wondering what Wired/Active/Inactive/Free was.

    What is this LG/CD modem? I don't have one but it's showing up. Any ideas?

    This will explain:
    Mac OS X: Reading system memory usage in Activity Monitor

    To determine if you can benefit from more RAM, launch Activity Monitor and click the System Memory tab at the bottom to check your page outs. Page outs are cumulative since your last restart, so the best way to check is to restart your computer and track page outs under your normal workload (the apps, browser pages and documents you normally would have open). If your page outs are significant (say 1GB or more) under normal use, you may benefit from more RAM. If your page outs are zero or very low during normal use, you probably won't see any performance improvement from adding RAM.

    Perhaps one you've connected to in the past?

    Yeah my page outs aren't anywhere near 1 Gb...my order is almost here and I don't want to deal with the hassle of a return and pay for shipping (I got it for $30)...so I'm guessing it wouldn't hurt to install it if I can afford it.

    So that freezing/congestion wouldn't get any better with more RAM?

    Not likely. You need to find the source of the problem, and RAM doesn't appear to be the culprit. This may help:
