Alternatively referred to as main memoryprimary memory, or system memoryRAM (random-access memory) is a hardware device that allows information to be stored and retrieved on a computer. RAM is usually associated with DRAM, which is a type of memory module. Because information is accessed randomly instead of sequentially like it is on a CD or hard driveaccess times are much faster. However, unlike ROM, RAM is a volatile memory and requires power to keep the data accessible. If the computer is turned off, all data contained in RAM is lost.

As the computer boots, parts of the operating system and drivers are loaded into memory, which allows the CPU to process the instructions faster and speeds up the boot process. After the operating system has booted up, each program you open, such as the browser you're using to view this page, is loaded into memory while it is running. If too many programs are open, the computer will swap the data in the memory between the RAM and the hard disk drive.

A computer's performance is largely attributed to the amount of memory contained within it. If a computer does not have the recommended memory to run the operating system and software programs being used, it will result in slower performance. The more memory a computer has, the more information and software it can load and process quickly.
