RAM (random access memory) is used for temporary storage of program data, allowing optimal performance. Sufficient memory enables faster communication between the processor and hard drive, enhancing the performance, speed and access time of your computer, which allows you to accomplish more tasks in a shorter amount of time. Upgrading the RAM is one of the most efficient and cost-effective ways to boost your PC’s overall performance. Smoother multitasking Do you open several programs at the same time and switch between them frequently? Does it seem like your computer takes forever when you are switching between the different applications? Then a memory upgrade is essential for smooth, effortless multitasking. It gives your computer an extra boost so it doesn't have to use the hard drive to manage data. Faster Web surfing If you like to spend countless hours on the Internet, but don't like it when your system seems to slow to a crawl, you'll want to add more memory. No matter how fast your Internet connection may be, by simply upgrading your memory you can help your browser display pages faster. When your computer can store more data in the RAM, it has to swap out less memory to the hard drive. More efficient video editing If the video-editing bug has bitten, you'll want to add RAM. Editing is fun — or can be if it's not too slow. Because video files are very large, you'll not only need a big hard drive to store the file, but a quick processor and lots of RAM to help speed things up. Enhanced multimedia presentations Intense graphic use and memory grabbing programs, such as multimedia, publishing and graphics arts, demand more RAM for the optimal computing experience.
