RAM stands for Random Access Memory, a modular computer component that allows your system to temporarily store and retrieve data extremely fast. Your computer loads a program or file you select from the hard drive in to your computers RAM, then it will access each bit of data from there. Unlike hard drives, data stored in RAM does not remain in memory after the machine is powered off. Most computer manufacturers will include a minimal amount of RAM from the factory (OEM) with extra empty RAM slots to upgrade the machine to your liking. Because nearly every operation is dependent on a computer's memory, the amount of RAM your computer has plays a critical role in the speed of your system's performance. For this reason, an upgrade to your RAM is one of the easiest and most affordable ways to extend your computer's lifespan.
