Web Host w/ Lots of Bandwidth

[Grizzly]

If not, I'd suggest reading it.

And now, to answer your questions:
Alas, another victim of unlimited hosting. Personally I think the FCC should start hammering these hosts that do these marketing gimmicks, most shared hosting has a limit on resource usage, usually 25% of server resources for a continuous 30-90 seconds.

Now, a VPS is a Virtual Private Server. It is basically a bunch of baby dedicated servers spawned off of one dedicated server. Performance really isn't that great. I would just start with shared hosting (unless this is the site you were talking about in the other thread) and upgrade as needed, no need to spend more money than you need to. And most sites rarely see 100k / day. If you are seeing that you'll be making more than enough money to pay for the 2 - 3 servers required to run that thing (and keep load times way down).

Honestly, if you are really thinking you'll see that much, get a VPS. A MANAGED VPS. And make sure you read and ask the host specifically what is covered. If they say everything take that deal ;)

Think of a server as a large computer, because that is all it is.

Each process run uses RAM just like your computer. Each time someone clicks a link there is a process. Your control panel will use RAM. And some things like Apache will always be there running. On a VPS don't bank on that burstable/maximum RAM. Go with whatever they say is dedicated to you.

CPU...same thing as above.

Processor type: Usually they will say a dual quad core or something to that effect. Basically each core is separate and will spread the processes over each one.
