When running programs, computers have to access certain data frequently. The computer stores these data in your RAM. More RAM means that your computer can manage more applications.
If your RAM is full and your computer still needs instant access to a lot data, it will store the excess data in your hard drive. This can create problems because the data stored in the hard drive cannot be retrieved as fast as data in the RAM. Thus, you will experience significant lags and loading times when you are multi-tasking in a computer that low RAM.
RAM is measured in megabytes or gigabytes. You can buy RAM memory modules in various storage capacities, including 256MB, 512MB, 1GB and 2GB. Your motherboard dictates the number of memory modules that you can use. Motherboards usually have only two slots for memory sticks. Modern motherboards can allow you to use more than two RAM modules.
If you intend to use Windows Vista as your operating system, try to get at least 2GB of RAM. Vista is a demanding program that will need a robust system.
Your motherboard also determines the type of RAM that you can use. There are three types of RAM memory used in computers today: DDR, DDR2 and DDR3. DDR3 is a relatively new technology so only the latest motherboards can support it.
So when building a computer, always get as much RAM as you can get your hands on! More RAM will not only permit you to run several programs together, it will also significantly increase the speed of your home built computer.
