The correct answer is: C. A collection of software routines
An operating system (OS) is a system software that manages computer hardware and software resources and provides common services for computer programs. Operating systems are found on many devices that contain a computer, including cell phones, tablets, personal computers, and servers.
The main functions of an operating system include:
- Resource management: The operating system manages the computer’s hardware resources, such as the CPU, memory, and storage.
- File management: The operating system manages the computer’s files, including creating, deleting, and accessing them.
- Process management: The operating system manages the computer’s processes, including scheduling them and allocating resources to them.
- I/O management: The operating system manages the computer’s input and output devices, such as the keyboard, mouse, and printer.
- Security: The operating system provides security features to protect the computer from unauthorized access and malicious software.
A collection of hardware components is not an operating system. Hardware components are the physical parts of a computer, such as the CPU, memory, and storage. A collection of input-output devices is not an operating system. Input-output devices are the devices that allow a user to interact with a computer, such as the keyboard, mouse, and printer.
All of the above is not the correct answer because an operating system is not a collection of hardware components, a collection of input-output devices, or all of the above. An operating system is a collection of software routines that manage the computer’s hardware and software resources and provide common services for computer programs.
