Final answer:
The correct answer is c) both (a) and (b). Resource management in an operating system can be done through both time division multiplexing and space division multiplexing.
Step-by-step explanation:
The correct answer is c) both (a) and (b).
Resource management in an operating system can be done through both time division multiplexing and space division multiplexing.
Time division multiplexing (TDM) is a technique where resources are allocated to different users or tasks based on time slots. Each user or task is given a specific time slot during which they can access the resource.
Space division multiplexing (SDM) is a technique where resources are allocated to different users or tasks based on physical space. Each user or task is given a separate partition or section of the resource.
By using both TDM and SDM, an operating system can effectively manage and allocate resources to different users or tasks.
