Last time we learned about the hard drive and this Wednesday we’re talking RAM, as in Random Access Memory. It’s the thing you hear about when buying a computer or if you want to upgrade and the more of it you have, the faster your computer is.

The term ‘random access” in Random Access Memory comes from the fact that you can access any part of the memory at any time. At the time the term was coined, it was different from sequential memory which was being used such as tape, where you had to fast forward or rewind to get the part of the tape you needed. Now, most computer memory is non sequential so the term is kind of an antiquated one but it sticks.
There are three important things about RAM I want to tell you. First, RAM is the place that your programs and operating system and stuff hang out while you’re using them. Let’s say you open a program, the browser that you’re using for example. Your hard drive stores all the files necessary to use the program but your hard drive is not really that fast so RAM takes the stuff you’re using off your hard drive and holds it for you, making it a much faster process. People compare RAM to a desktop and the stuff on your hard drive as a file cabinet. You take the stuff out of the cabinet and put it on the desktop so you can use it. Bigger desktop, more stuff you can have on the go and the faster you’ll be able to work. It’s a good analogy but where I am in my life lately I’m more apt to think of the hard drive as my children’s’ toy box and the RAM as the playroom. There’s tons of stuff in the toy box and most of it never gets used. Whatever toys they’re playing with are on the floor and the bigger the floor, the more toys they can have out of the toy box where they can be easily and quickly accessed.
The second point I want to make about RAM is that it is temporary. Once you turn off or restart your computer, all the stuff that was in it is cleared out to make room for you to start over again. So that 30 page research paper you were working on but didn’t save is gone once your computer restarts, unless you save it on the hard drive. In these days when you probably leave your computer on for long periods of time, you should restart your computer every few days or if you notice your computer having problems. Just like when I go insane when I can’t walk around on the floor because of all the toys cluttered there, your computer just needs everything cleared out every now and then to make things work better.
The third thing I want you to know about RAM is that it is one of the best ways to speed up your computer. Now, if you have an old 286 and want to run Windows Vista, all the RAM in the world won’t help you but if you have a relatively new computer and would like to speed things up a bit, especially if using memory-intensive games like 3D video games or photo editing software, buying RAM is a fairly inexpensive way to do this. You have to make sure you have the right kind of RAM for your computer though (you didn’t think they’d make it easy and just have one kind of RAM did you?) so make sure of what you need before you buy. You can install it yourself if you dare, as you basically plug in RAM but beware that opening your case can void most warranties and you can screw up your computer if you’re not careful installing RAM. If you do want to try it, just google it or check out the many videos on youtube about installing RAM.
Now, I’m going to restart my computer right before I clear all these toys off the floor.
