Computer software, does not deal with the physical interconnection of devices and components as computer hardware does: It deals with the ordered, sequential instructions used to change a processor's state from it's previous state. Each instruction, written in groups of binary digits to form code, builds on the last to form a seemless flow that ends up, upon completion of developement, being the operating systems, programs, and applications that we use daily. The people who make this possible are the software developers and programmers.
There are 3 basic catagories of software: system, application and programming. We wont get into programming software because, as you have already guessed, is used by programmers.
- System software helps run the computer hardware and computer system. It includes operating systems, device drivers, diagnostic tools, servers, windowing systems, utilities and more. The purpose of systems software is to insulate the applications programmer as much as possible from the details of the particular computer complex being used, especially memory and other hardware features, and such accessory devices as communications, printers, readers, displays, keyboards, etc.
- Application software allows end users to accomplish one or more specific (non-computer related) tasks. Typical applications include industrial automation, business software, educational software, medical software, databases, and computer games. Businesses are probably the biggest users of application software, but almost every field of human activity now uses some form of application software. It is used to automate all sorts of functions.
- Programming software provides tools to assist a programmer in writing computer programs and software using different programming languages in a more convenient way.
