Well... if happens all the time that an OS (WinXP for example) needs more memory than there's in a computer. As it can't use any more memory for e.g. userdata, it has to store that data somewhere. That place is the harddisk. Although this solves the lack of memory (in most cases), it's not ideal, as the harddrive is way slower than the internal memory is.
If you got lots of RAM in your system, you could configure Windows in that way, that nothing will be written to the harddisk, but only to the internal memory. In XP, you can do this from the "performance' menu, that can be accessed from the System manager.
In your case, you'd better leave that option alone. I wouldn't advise it to anyone with less than 1,5Gb of internal memory.
