FAQs on System Software & Operating System - MCQ with answers - Computer Science Engineering (CSE)

1. What is system software?
Ans. System software is a type of software that is designed to manage and operate the computer hardware, software, and resources. It provides an interface between the user and the computer hardware. Examples of system software include operating systems, device drivers, utility software, and programming language translators.
2. What is an operating system?
Ans. An operating system is a type of system software that manages the computer hardware and software resources, and provides common services for computer programs. It acts as a communication bridge between the user and the computer hardware. Examples of operating systems include Windows, macOS, Linux, and Android.
3. What is the difference between system software and application software?
Ans. System software is a type of software that manages and operates the computer hardware, software, and resources. It provides an interface between the user and the computer hardware. Application software, on the other hand, is a type of software that is designed to perform specific tasks for the user. Examples of application software include word processors, spreadsheets, and web browsers.
4. What are the functions of an operating system?
Ans. The functions of an operating system include managing and allocating computer hardware resources such as the CPU, memory, storage, and input/output devices. It also provides a user interface to interact with the computer hardware, manages the file system, and provides security and protection for the computer system.
5. Why is an operating system important for a computer system?
Ans. An operating system is important for a computer system because it manages and controls the hardware and software resources, provides a user interface for the user to interact with the computer, and ensures that the computer system runs efficiently and effectively. It also provides security and protection for the computer system by controlling the access to resources and preventing unauthorized access.
