Frequently Asked Questions

What is the main difference between system software and application software?

System software is responsible for managing computer systems and running hardware, while application software is designed for end-users to perform specific tasks or functions.

What are some examples of system software?

Examples of system software include operating systems like Windows, macOS, and Linux, device drivers that enable hardware devices to communicate with the computer, utility software for system maintenance and optimization, as well as translators and library programs that assist in software development.

What are the categories of application software?

Application software can be categorized into three types: general-purpose software, which includes programs like word processors, spreadsheets, and web browsers that cater to a wide range of user needs; special-purpose software, which is designed for specific tasks like graphic design, video editing, or accounting; and custom-written software, which is developed specifically for a particular organization or individual's unique requirements.

What is open-source software?

Open-source software refers to software that is freely available and can be modified and distributed by users. It is developed collaboratively by a community of programmers, and its source code is openly shared. Examples of open-source software include the Linux operating system, the Firefox web browser, and the LibreOffice suite.

How does proprietary software differ from open-source software?

Proprietary software is owned by a specific company or individual and is distributed under a license that restricts its modification and distribution. Users typically need to purchase a license or pay a fee to use proprietary software. In contrast, open-source software allows users to freely modify and distribute it. It is developed by a community of programmers who openly share the source code. Examples of proprietary software include Microsoft Office, Adobe Photoshop, and Apple's macOS operating system.
