Running out of memory is something we wish to avoid. All operating systems use virtual memory, a part of your mass storage set aside to act as (very slow) memory if your real memory runs out. If your computer is using virtual memory, you add more RAM to the system.
- There's an old adage that says you can't be…too rich or too thin.…Now, I may not totally agree with that,…but I'll put a corollary to it…and I'm going to say you can't have…too much RAM in a computer.…Everything you do on your computer counts on your RAM.…Every active program that's running needs RAM…in order to have the workspace it needs…to do what it needs to do.…Now, if you run out of RAM,…you could run into a big problem.…Let me show you what I'm talking about…using a beaker I've got over here.…Here's a graduated beaker.…
Now, this beaker's going to represent…all of the memory, all the RAM in my computer.…So you'll see I've got it graduated…from zero up to 16 gigabytes because, well,…that's how much memory I have in my PC.…Now, when I boot that computer up,…some of this is going to be used…for the operating system itself.…So in Windows, it's usually around two gigs.…Now, as we begin to load more and more programs,…they begin to take up more and more space in this beaker.…So, some programs are fairly small…
