I'm working on a science project for school. Here's what I'm trying to do: I am trying to figure out what affects a computer's (in my case my black MacBook 2.2)speed most, CPU, RAM, cache,etc. All i have right now is my MacBook to test on, it has 4gig ram which I have upgraded from 1gig. Now, is it ok to mix the original ram that came w/ the mac with the new ram to make laptop have 2.5gigs of ram? Also i also have a cousin w/ a black MacBook too, but the gen before mine, i think it's 2.0 ghz, that i might be able to test on. The comps at my school are all dells, so idk if it would be a good idea to mix the platform of os during the experiment; but i could also test which os runs faster while loading certain webpages, or something like that...So you can easily see how many variable I have to consider in this project Have you cool cats got any suggestions on how I should start getting some good data? What makes it even worse is that it's due by this Tuesday! Ya, I have a week from today to do this, so please keep that in mind. Thanks so much in advance!
