definition of computer software and the examples

1)Software is a generic term for organized collections of computer data and instructions, often broken into two major categories: system software that provides the basic non-task-specific functions of the computer, and application software which is used by users to accomplish specific tasks.

2)System software is responsible for controlling, integrating, and managing the individual hardware components of a computer system so that other software and the users of the system see it as a functional unit without having to be concerned with the low-level details such as transferring data from memory to disk, or rendering text onto a display. Generally, system software consists of an operating system and some fundamental utilities such as disk, file managers, display managers, text editors, user authentication and management tools, and networking and device control software.

3) Application software, on the other hand, is used to accomplish specific tasks other than just running the computer system. Application software may consist of a single program, such as an image viewer; a small collection of program.

4)Software is created with programming languages and related utilities, which may come in several of the above forms, single programs like script interpreters, packages containing a compiler, linker, and other tools and large suites (often called Integrated Development Environments) that include editors, debuggers, and other tools for multiple languages. 

System Software have direct control and access to your computer hardware, and memory locations. 

They perform I/O operations on various memory locations, and control the hardware, to make the application software do a task.Operating systems, are the main examples for system software .
