As it is well known , a computer cannot perform or complete any useful work unless it is able to communicate with its external environment . All data and instructions enter and leave the central processing unit through primary storage . Input-output devices are needed to link primary storage to the environment , which is external to the computer system . So input devices are used to enter data into primary storage . Output units accept data from primary storage to provide users with information or to record the data on a secondary storage device . Some devices are used for both the input and output functions .
The data with which these devices work may or may not be in a form that humans can understand . For example the data that a data entry operator keys into the memory of a computer by typing on a keyboard are readable by humans . However , the data that tell a computer about the performance of an automobile engine are not in a form that humans can read . They are electrical signals from an analog sensor . Similarly , output may be on a printed page , which humans can read easily , or upon some other medium where the data are not visible , such as on magnetic tape or disk . As we know , all of the data flow from input to final output is managed by the control unit in the CPU . Regardless of the nature of the I / O devices , special processors called I / O interfaces are required to convert the input data to the internal codes used by the computer and to convert internal codes to a format which is usable by the output device .
