Basic Computer Terms RAM & Hard Drive Explained
When it comes to a computer, there is so much basic computer terminology that people find confusing such as RAM, mhz, gb and morethat can confuse people and leave them asking questions like “What is RAM?”, “What is a hard drive?”.
Having a better understanding of some of the jargon can can help tame your fears of the computer, which can help you get more out of them.
A lot of people I talk to seem to be apologetic about their lack of knowledge. It’s too bad people feel that way; they really shouldn’t.
What I tell them is that while they may not know as much as I do about computers, it’s really not their fault, and they probably know a lot of other things I don’t know much about. All you need is someone who takes the time to explain things to you in a way that makes sense.
One term many people confuse is memory (also known as RAM), and hard drive storage space.
RAM stands for Random Access Memory (relax — you don’t have to memorize that). It is a temporary working space the computer uses to get work done, which gets emptied when the computer is turned off.
Think of it like a work bench or table. You have a project you’re working on and you do your project on the table and when you’re done, you clear it off.
The hard drive is the main place your computer uses to store information. It looks like a rectangular metal box about 3.5″ wide (or 2.5″ on a laptop), which contains a non-removable disk. It is the disk inside the drive which stores everything.
Think of it as a closet where you store the tools or materials for your project — when you want to work on something you choose the things you need from the closet, put them on the bench and work on the project.
This is like when you run a program; the computer loads the program from the hard drive into memory.
So the larger the space, the more you can store — so in other words the more programs you can have installed, the more songs or pictures or videos you can save on your computer.
Many people accidentally call their computer (the big box-like thing hooked up to the screen) a hard drive, but this is based on a misunderstanding. Both RAM and the hard drive are parts located inside of the computer, and most people never actually see these parts.
Most people who own a computer that’s only a few years old have far bigger hard drives than they’ll ever could ever hope to fill. Few people ever fill them up, unless they are downloading a lot of large files such as music or pictures, or especially video files. Saving a complete movie on your computer can really eat up space very quickly.
If someone tells you need more memory, or or you get an error message about not having enough memory, this usually means you don’t have enough RAM. This can slow your computer down drastically.
Think of the bench idea again: if your bench is very small, you can’t fit everything you need on it to get your work done, so you’re constantly wasting time moving stuff off and back onto the table to get your work done, if you can do any work at all.
Both RAM and hard drive space are measured with the same terms: kilobytes (KB), megabytes (MB), and gigabytes (GB). This may be one reason people confuse the two terms.
So why is it that you buy a computer one year that has a lot of RAM, and two or three years go by, why do people tell you you don’t have enough RAM? This is because each year the average size of software, and the amount of memory it requires, gets bigger.
It’s as if the tools you use on your workbench keep growing every year so you eventually have to get a larger bench.
If your computer seems to be running more slowly recently, or you’ve been having odd errors, it could be that you need to add more RAM, which is inexpensive and can add life to your computer. It’s not a cure-all for a slow computer, but it can make a real difference.
Remember, basic computer terms doesn’t have to be frustrating, just as long as the explanation makes sense!
