RAM (Random Access Memory)

RAM is your system's short-term memory. This short-term memory disappears when the computer is turned off. RAM is measured in megabytes (MB) or gigabytes (GB). The more RAM you have, the more things your computer can do at the same time. If you don't have enough RAM, you may notice that your computer is slow when you have several programs open. Because of this, many people add extra RAM to their computers to improve performance.

Hard Drive

The hard drive is where you store all your information. The hard drive is long-term storage, which means the data is still saved even if you turn the computer off or unplug it. When you run a program or open a file, the computer copies some of the data from the hard drive onto the RAM so that it can access the data more easily. When you save a file, the data is copied back to the hard drive. The faster the hard drive is, the faster your computer can start up and load programs.
