Q. And, how do you show how much memory and cpu each is using?
A. Check out the manpage for ps. The most common syntax is "ps auxww" which will show PID, CPU usage, Memory usage, process name, etc for each process that is running on your system. "top" shows real time information and ranks processes by their CPU/RAM usage.
What slows down computers besides memory usage?
Q. I just deleted a whole lot from my laptop, and I ran a 'defragmentation' on the hard-drive, but it's still going really slow. Any ideas?
More detail: It's slow to open programs or new windows. There's a delay between when I click an icon and when the window opens.

A. Are you familiar with the Task manager? (Ctrl+Alt+Delete) The task manager will show you which processes are using you processor power and how much virtual memory.
What version of Windozes? Have you tried using a registry cleaner? Do you have a reliable anti-virus?
When I used to use Windozes, I had to wipe it about every 6 months and start over. It just seemed to get unstable after prolonged use. I now use Ubuntu Linux.

What operating system should i install on a VERY old computer?
Q. The computer again is extremely old, ie 5-6 years (integrated graphics, 1 gig ram, pentium processor, etc). Now i want to find an OS that is both simple to use and one that will run efficiently, especially for viewing photos and movies (obviously this is bottle-necked by hardware, but there should be differences in memory and cpu usage from OS to OS),
So what do you suggest? the new chrome OS, win XP, ubuntu?

A. Old machines run best on what they were designed for, But time marches on and computer os support runs out of steam. If your machine was designed for XP os then use it, upgrade as much of the hardware as economical and go from there. You may find it would be best to purchase a new machine rather then try to upgrade on your own. If that is not an option and you are determined then you should start with the memory, then the video card. If your machine is at least a P4 running at close to 2.0GHz then you will have a chance depending on your technical ability. If not then you should shop the internet for a used system that is within the price range of what you are going to spend on upgrading your machine. To answer your question Google Chrome OS is only to be used for the modern netbooks (condensed and stripped down laptop computers), Win XP was most likely the OS that was installed at the factory on your machine, and Linux Ubuntu is free and open source software.... XP is my choice
