Re: ram/memory/hard drives?
Your hard drive is permanent storage, RAM is temporary, RAM is much, much faster.
When you put in a CD and install an application, you are copying it from the CD to your hard drive. Then, when you actually run that program, it is copied into RAM, so that the application is not outrageously slow. Running an application from your hard drive will greatly slow it down, and that is exactly what is happening when you run out of ram, hence why more ram can mean a faster computer.
If you have 512 mbs of ram, then you can load in 512mbs of programs, including the operating system, as well as files, at any given time without experiencing a slowdown. If this happens, the only way to regain speed is to close programs, or add more ram.
So increasing ram can speed up your computer. Increasing a hard drive can't, not really anyway. There will be a marginal lag in copying from hard drive to ram that can be cut down, but it is not nearly as noticable, and has nothing to do with the size of the hard drive, but rather the speed.
