*      Introduction


You may have used the computer to store games, music files and pictures in it. These files get stored in the memory devices. A memory device is a device that preserves information (data and instructions) for retrieval in the future. Every computer uses storage to hold software such as system software and application software. To boot up, a computer locates an operating system (system software) in the storage and loads it into memory. When users issue commands to start application software, such as word processing, the operating system locates the program in storage and loads it into memory. In this chapter, we will learn about some characteristics of memory devices.
