Data storage device a data storage device is a device for storing information (data). computer data storage: capability of the computer to remember data is called computer data storage or memory. Computer systems consist of four basic parts: input devices, output devices, the central processing unit, and secondary storage. input devices send data to the computer from the outside world. common ones are the keyboard, the mouse, and the touchpad. some systems have microphones. The basic resources of complete computer systems are the cpu, instruction and data caches, main memory, peripheral devices, busses for the interconnection of these components, and some interfaces that implement the data exchange protocols.

The basic resources of complete computer systems are the cpu, instruction and data caches, main memory, peripheral devices, busses for the interconnection of these components, and some interfaces that implement the data exchange protocols. Data and programs are stored as files in the secondary storage of a computer system. file management involves the creation, updation, deletion and protection of these files in the secondary memory. – processor ("central processing unit" or cpu) does the work, controls the rest – memory (ram = random access memory) stores instructions and data while computer is running – disks ("secondary storage") stores everything even when computer is turned off – other devices ("peripherals"). Assume that part of the program’s task involves reading a data file from the disk into the memory, performing some computation on the data, and printing the results. Computer system structure objective: general knowledge of the structure of a computer system. tape drivers disks device controllers: synchronize and manage access to devices.
