1.2.1 (a)(b) Memory management and OS

An operating system is defined as:

• A software that manages computer hardware and software resources and provides common services for computer programs.

• A device used to store data permanently.

• A programming language used to develop applications.

• A type of computer network.

The different functions of an Operating System include:

• Process management, memory management, file system management, and device management.

• Only running applications.

• Providing internet access only.

• Creating hardware components.

The difference between paging and segmentation is:

• Paging divides memory into fixed-size blocks, while segmentation divides memory into variable-sized segments.

• Paging and segmentation both divide memory into fixed-size blocks.

• Paging uses variable-sized segments, while segmentation uses fixed-size blocks.

• Paging and segmentation are identical memory management techniques.

Operating systems perform functions such as memory management, which can include techniques like paging and segmentation.

• Paging and segmentation are memory management techniques used by operating systems.

• Paging and segmentation are types of hardware devices.

• Operating systems do not manage memory.

• Paging and segmentation are only used in application software.

Which of the following does the operating system manage?

• Hardware

• User interface

• Software

• All of the above
