Hi Chabib,
Caching is a means of storing recently accessed data for quicker retrieval.
In essense, the system does not have to "go looking" for it, it's already
there. This is useful when a program or routine reuses the same data over
and over, as it can speed the routine up by eliminating (or cutting down on
really) the seek and retrieve step. A similar function exists for the cpu,
and within programs on your machine. One example is the temporary internet
files, which stores information from recently accessed web pages. When you
revisit those sites, the system simply loads the data you already have,
rather than redownloading it from the site. It's a bit more complicated than
that (has to check for updated information and such as well), but this is
essentially how it works.

I have a lot to learn about computers. I recently had a 40g hard drive,
7200 speed, installed replacing a 20g. and I was told that my cache
increased fron 200 to 800. What does that do to my computer and what the
heck is cache? Thanks in advance.
