Random Access Memory Computer

RAM is an energy device, in other words, the information is stored in RAM chips only until on a computer memory motherboard supplied power. When you shutdown or reboot when all the data stored in RAM is destroyed and then again placed in the RAM in the re-PK.

In addition to programs in RAM temporarily stored all the information that at the current moment is the user, for example, there is stored edited them at the time the text or hear the melody. Once the user completes the session with a given file, it is remove from memory to make it a place for other data. In order to understand the working principle of RAM, you can compare it with a camera store large station, which for each subject given his own cell with an individual number - the number of cells known as RAM memory addresses.

When the processor requires any data, it extracts them from the cell storage with the number - requests from the sun memory with a given address, and the vacant slot, he can put any other details, such as the result of processing the previous command. The amount of RAM is a modern computer is measure in megabytes (Mb) and can reach even several gigabytes. Physically, in the architecture of the personal computer memory is represented in the form of a small fee or more cards, containing a set of special chips. One such fees, which are called memory modules, has a finite amount of megabytes, which is typically a standard value, for example, 64, 128, 256 or 512 Mb. RAM modules are installed in special connectors on the motherboard computer. Let us consider the existing standards of memory modules in more detail.
