There comes a time when you just don't have enough memory. In the very beginning, everything was perfectly fine. Then after a few years of use, your desktop or laptop computer starts running slower and slower. Sometimes you are simply surfing the Internet, doing word processing, or listening to your music collection while running other applications, and suddenly your computer can’t keep up.
If your hard drive's activity light is blinking furiously, it means the drive is way too busy and, it is about time to install more memory (RAM). To understand why, just think of the computer's CPU as a chef, its hard drive as a refrigerator, and the RAM as a kitchen countertop. To cook a meal, the chef (CPU) has to take out the necessary ingredients (data) from the refrigerator (hard drive), and works with cooking gadgets on the countertop (RAM). As orders (applications) increase, more working space is therefore required.
So what takes up the most countertop space (memory) on your computer? Take Windows XP for example. Entering the desktop will take up 300 to 500 MB of memory, while opening a popular Flash game on FACEBOOK will need at least 250MB more. Even two Flash games can eat up 1GB of precious memory! It's lucky that you don't have to upgrade your whole computer to get more space, though. Instead, adding more RAM to your computer is much easier and more cost effective.
Usually a desktop computer has two to four memory slots, and a laptop has two. For most of users, 1.5GB to 2GB of memory will be sufficient. Before you install extra RAM, make sure that the memory you add is identical to that already in your computer. Lastly, be smart and choose a trustworthy brand.
