I feel I need to write this article because to many people get memory mixed up with storage. I am not going to reinvent the wheel here. I have put some links to sights that I feel explain the subject pretty good. If you buy something off their sites so be it.
Memory is your working space. If you didn’t have memory you couldn’t even type a letter, run a program or anything else. It is the life blood of why computers work in the first place.
The main kind of RAM in today’s computers is Synchronous Dynamic RAM (SDRAM). However, numerous types of RAM exist. This is due to the fact that computers keep changing. Technology changes so fast that it is all but imposable to keep up with. You need to be sure what type of RAM you have in your computer before you upgrade. Types of memory
What if you run out of memory (RAM)?
This would not be good! The first thing you will notice is that it gets difficult to get anything done. It slows down everything you are trying to do. When this happens the program you are running will attempt to find memory any place it can get it. The only place to go is the hard drive. This is called paging. The problem is that it will attempt to access areas of the hard drive that are already being used. Certain programs can take up a lot of memory and once in a while it is a problem when your trying to work with a lot of programs at a time.
How can I solve this?
There are two things you need to look at.
- How big is your hard drive? If your hard drive is almost used up this could be a big problem and may in fact cause a crash if there isn’t enough room to start with.
- Can you add RAM? Hopefully your motherboard will allow you to add more RAM. Put in as much as you can afford. This is the single best thing you can do to upgrade and improve the performance of any computer.
- You should close any programs your not using. I feel this is important. It may make your day a lot easier because it will speed up the program you are actually working on.
What if my computer is still slow?
You may have a Virus. This is the main cause of this symptom. There are numerous other possibilities but this is the big one. Spy-ware is also a possibility. If you feel you have run out of energy trying to figure it out I feel you need to take it to an expert in your area.
