Software:
a) Instructions (Computer Programs) that when executed provide desired features, function, and performance.
b) Data structures that enable the programs to adequately manipulate information.
c) Documents that describe the operation and use of the programs.
Evolutionary Role of Software
Software performs 2 roles
1. Product – As a product, it delivers the computing potential embodied by computer hardware or, more broadly, a network of computers that are accessible by local hardware.
2. Vehicle/ Platform – As a vehicle used to deliver the product, software acts as the basis for the control of the computer (operating systems), the communication of information (networks), and the creation and control of other programs (software tools and environments).
