Have you heard the old saying that our grandparents studied the 3 R's
. Reading, Riting, and Rithmatic? OK, I'm sure it was even corny back then But today, at least in computer maintenance, it is the 2 R's. Registry and RAM. What is RAM and how can it increase computer speed?
First, see where your computer stacks up right now. Go to your control panel and find System or System Information. There you will see some general information on your computer such as Model, Processor, etc. The RAM will be listed as Memory or maybe SDRAM. From XP forward computers need at least 1 gigabyte but really 2 gb is much better even in older models. You can't have too much and it is not expensive.
But what is it? Random Access Memory is your computer's working memory. It is a non-moving stick or small circuit board that is attached to the Mother Board of the PC by being plugged in. This is in contrast to the main drive storage disc that is just that, a "disc" similar to a DVD that moves when being accessed.
There is almost always room or slots for additional RAM to plug-in to the mother board and add to its capacity. On a desktop this is pretty easy by opening the side of the case. A laptop is a little more difficult and you should be careful about breaking warranty seals on new notebooks.
To add more RAM I would suggest taking in your present stick or circuit board to a local PC shop. There are different types and speeds and you need to match it exactly. The pictures here are pretty accurate as to the RAM and the mother board with the slots where the RAM is plugged in. You can remove it by taking off the case side panel and pulling it with your fingers. Don't use pliers or anything that will crimp or scratch it. (and of course have the PC off and unplugged!)
