The way information is stored in a variety of computer, but the main 2, RAM, hard drives, also known as the hard disk.

The hard drive is a huge amount of information to save and protect this information to suit the computer when the power is turned off... The only problem is that too much time on your hard drive - to search for and consumption data from the scheme because they need to wait for some of the disk spin to the right under the surface of the disk read heads, and then drive to transfer data to block the order.

At this time, because it uses the information system is needed to obtain that information very quickly. What part of the suit. This information is stored in RAM space, which is arbitrary - access to memory. Navigation systems to save all random access operation, the image data to an arbitrary line immediately, without waiting to be sang.

Random access, and faster, than the sequential approach. The main reason for all the shops as well as computer memory, RAM to display the information is lost when the power is turned off. Therefore, both the computer's memory and disk space. All are stored on a disk, in the long run, what is needed at this time, RAM copy suit. If changes are made in a RAM data on changes that must be omitted, and a computer disk copy before the power is turned off, so these changes are lost.

People talk about the computer's memory, meaning they are almost always RAM, or hard drive or other form of storage capacity does not yet cover. Sometimes they say 'main memory' only completely eliminated.
