  13. 13. Primary Storage Devices Alternatively referred to as internalmemory ,main memory, primary storage is a storagelocation that holds memory for short periods of timeswhile the computer is on. For example, computer RAM and cache are both examples of a primary storagedevice. This storage is the fastest memory in yourcomputer and is used to store data while its being used.For example, when you open a program data is movedfrom the secondary storage into the primary storage. RAM and ROM are the Primary Storage of theComputer 13

  26. 26. Summary Storage Device are device we used to storeprocess information. They may be primary orsecondary storage devices Primary storage devices are those storagewhich are part of the computer. Computers will notbe able to run without it. Primary memory are theRAM and ROM. Secondary storage devices are those storage which can be taken out of the computer. They may be an optical disk, magnetic disc or mass storage device. sgisave@in.com 26
