Software, commonly known as programs, consists of all the electronic instructions that tell the hardware how to perform a task. These instructions come from a software developer in the form that will be accepted by the operating system that they are based on. For example, a program that is designed for the windows operating system will only work for that operating system. Compatibility of software will vary as the design of the software and the operating system differ. A software that is designed for Windows XP may experience compatibility issue when running under Windows 2000 or NT.
Software can also be described as a collection of routines, rules and symbolic languages that direct the functioning of the hardware.
Software is capable of performing specific tasks, as opposed to hardware which only perform mechanical tasks that they are mechanically designed for. Practical computer systems divide software systems into three major classes:
- System software: Helps run computer hardware and computer system. Computer software includes operating systems, device drivers, diagnostic tools and more.
- Programming software: Software that assists a programmer in writing computer programs.
- Application software: Allows users to accomplish one or more tasks.
The term "software" is sometimes used in a broader context to describe any electronic media content which embodies expressions of ideas such as film, tapes, records, etc. Software is the electronic instruction that tells the computer to do a task.
