Software

The programs and instruction and instructions sets that operate the computer are called software or computer programs are collectively known as software. There are different types of software designed to do different tasks that are given below.

Practical computer systems divide software into three major classes:
1. System software
2. Programming software
3. Application software
1.1. System software: System software helps to run the computer hardware and computer systems. It includes operating systems, device drivers, diagnostic tools, servers, windowing systems, utilities and more. The purpose of systems software is to insulate the applications programming as much as possible from the details of the particulars computer complex being use, especially memory and other hardware features, and such accessory devices as communications, printer, readers, displays, keyboards, etc.
1.2. Programming software: Programming software usually provides tools to assist a programmer in writing computer programs and software using different programming languages in a more convenient way. The tools include text editors, compilers, interpreters, linkers, debuggers, and so on. An integrated development environment (IDE) merges those tools into a software bundle, and a programmer may not need to type multiple commands for compiling, interpreter, debugging, tracing, and etc., because the IDE usually has an advanced graphical user interface, or GUI.
1.3. Application software: Application software allows end users to accomplish one or more specific (non-computer related) tasks. Typical applications include industrial 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.
