• To provide an environment for running applications

• To increase processor speed

• To store user data permanently

Which task is a core function of an operating system?

• Designing user interfaces

• Managing memory allocation

• Creating application software

• Compressing files for storage

What is the main difference between a GUI and a CLI?

• A GUI uses text commands, while a CLI uses icons

• A GUI uses visual elements like icons, while a CLI relies on typed commands

• A GUI is faster than a CLI

How does memory protection benefit an operating system?

• It ensures applications use the same memory locations

• It prevents applications from interfering with each other’s memory

• It speeds up memory access times

• It reduces the need for virtual memory

What is virtual memory used for in a computer system?

What does process management primarily handle in an operating system?

• Allocation of resources and data sharing between processes

• Translation of high-level code to machine code

• Compression of files for storage

• Management of graphical interfaces

What is the role of a device driver in hardware management?

• To schedule processes

• To translate data into a format a device can understand

• To optimize memory usage

• To protect the system from viruses
