RAM or Random Access memory is essential to computer performance. RAM (random access memory) is the place in a computer where the os (operating system), application programs, plus data in present use are kept so they be able to be quickly reached by the computer's processor. RAM is much quicker to read from plus write to than the different kinds of storage in a computer, the hard disk, floppy disk, plus CD-ROM. However, the information in RAM stays there only as long as your computer is running. When you turn the computer off, RAM loses its data. When you switch your computer on again, your os plus additional files are once again loaded into RAM, usually out of your hard disk. A computer can't run with no RAM, plus computers work more effectively when more RAM is installed.

Description
RAM provides volatile, temporary data storage space. This means that what's kept in RAM is lost if the computer is restarted or shut down. RAM is found on removable chips, so RAM upgrades are common plus simple to make.
Purpose
Each time a program is running, it takes to continuously read plus write information to do its task. It writes most of this information to RAM but when RAM is insufficient, the program uses hard disk drive space instead of RAM.
Benefits
Increasing RAM will improve computer speed. A program can access RAM much faster than it can access a hard drive, optical drive or other storage devices. So programs run faster if they do not have to access information from drives.
How Big is RAM?
RAM is tiny, both in physical size (it be able to be kept in microchip modules) and in the quantity of information it be able to hold. It is much smaller than your hard disk. A typical computer can come with 32 million bytes of RAM plus a hard disk that be able to hold 4 billion bytes. RAM arrives in the form of "discrete" (meaning separate) microchip modules that plug into holes in the computer's motherboard. These holes connect through a bus or set of electrical paths to the processor. The harddrive, on the other hand, stores information on a magnetized surface that looks like a phonograph record. Today's personal computers come with 16 or more megabytes of RAM, usually increasing in multiples of 8 megabytes. Users of graphic applications usually need 32, 64, or 128 or even more megabytes of memory. Most personal computers are designed to allow you to add additional RAM modules up to a certain limit (e.g., up to 64 or 128 megabytes). Having more RAM in your computer reduces the number of times that the computer processor has to read data in from the hard disk, an operation that takes much longer than reading data from RAM. (RAM access time is expressed in nanoseconds; hard disk access time is expressed in milliseconds.)
