When describing functions or uses of something, first of all you tell the reader what it can do or can perform. Then you also need to indicate where it is used or who will use it. Now read the following examples. Describing Functions and Uses
Describing Functions and Uses What functions can be performed? The computer is a machine that performs tasks, such as mathematical calculations or electronic communication, under the a control of a set of instructions called a program. Programs usually reside within the computer and are retrieved and processed by the computer's electronics, and the program results are stored or routed to output devices, such as video display monitors or printers. Computers are used to perform a wide variety of activities with reliability, accuracy, and speed 。。00。0。0000●。0。。。000。00●。0●0。。。00。0。00。。0。0●。0。0。000。●0●
