RAM, or Random Access Memory, is separate from the memory on your hard drive. This is the physical memory your computer uses to carry out processes. The amount of RAM your computer needs is based on its use and specifications. For example, a computer with a 32-bit operating system typically can not make use of more than four gigabytes (GB) of memory so anything above that would be a waste. If you plan on running a 64-bit computer you may want to purchase one with more than 4GB of RAM. In this case it is important to consider the use of your computer.Never heard of this before? Get up to speed here. Having more RAM allows for quicker, better performance, especially for processes that require temporary data storage. This means things like surfing the web, gaming and switching between programs will be smoother with more RAM. At the moment, 4GB is enough for average computing needs while 8GB allows for a slightly more powerful computer with room to grow. You can get even more RAM if you wish, the next step up is most commonly 16GB. One more thing, there are several speeds of RAM available today. It is important to keep the speed of the RAM in mind as well. Faster RAM will also increase your computer’s performance.
