Software Engineering – Introduction
Software is a collection of similar tasks that provides a single inter- face to the user to obtain the results for a variety of requests. Software is the controlling unit of a hardware component. Both the components complete the computer structure; software or hardware alone is useless. A memory device, a power unit, capacitors, resistors, processor, monitor, and cables to connect are the hardware components used in a computer. The software defines the functions of data transfer, path of control messages and transfer of input and output between the hardware.
