Answer: Operating System
Answer Explanation
Application Software:
Application software is computing software designed to carry out specific tasks other than one relating to the operation of the computer itself, typically to be used by end users. It is software that aids the user in executing tasks like doing online research, jotting down notes, keeping logs of accounts, setting alarms, designing graphics, recording audio and video, performing calculations, or even playing games. Application software is different from system software in a way that they are used by end users and are particular in their uses or tasks and perform the task that they are designed to do.
For example, the Railway Reservation System is an application software that is specifically designed for the purpose of reserving seats in the Railway or Aeroplane. Word processor and Antivirus programs are also application software that are particularly designed for their specific purposes such as creating, editing, or formatting test documents and protecting computer and personal data from malware, viruses, and cyber threats.
Examples: Adobe Photoshop, MS Word, MS Excel, Antivirus software, etc.
Operating System:
An operating system is a system software that manages your computer’s hardware and software resources. The operating system acts as an intermediary between users and hardware to coordinate tasks like running programs and handling files. An operating system allows you to interact with your personal computer, providing a user-friendly interface while efficiently managing system operations to make your computer function smoothly and securely. For example, when you click to open an application, the operating system of your computer allocates memory, sets up processes, and communicates with the CPU and storage devices to carry out your request.
Operating systems are essential for managing hardware, software, security, and user interactions. It enhances productivity by enabling multitasking, ensuring security, and optimizing performances across devices. There are many types of operating systems such as single-user and multi-user operating systems, real-time operating systems, distributed operating systems, network operating systems, and mobile operating systems.
Examples: Windows, Linux, MacOS, iOS, Android, etc.
