What defines the concept of hard affinity in terms of processor allocation for processes?

Restricting a process from running on certain processors

Forcing a process to run on a specific processor

Specifying a subset of processors on which a process may run

Allowing a process to run on any available processor

What characterizes the concept of soft affinity in an operating system?

Forcing processes to switch between processors at regular intervals

Randomly distributing processes across all available processors

Guaranteeing a process runs on the same processor

operating system has a policy of attempting to keep a process running on the same processor—but not guaranteeing that it will do so.

How does a single thread of control affect the task execution within a process in computing?

It allows the process to perform multiple tasks concurrently

It enhances the process's ability to execute tasks asynchronously

It enables the process to switch between tasks seamlessly

It restricts the process to execute only one task at a time

What characterizes a hard real-time system in terms of task execution?

Tasks are executed without any deadlines

Task deadlines are flexible and can be extended

Tasks must be serviced within their deadlines

Minimizing latency is a secondary objective

What does the term "virtual address" signify in the context of memory management?

The network address of a computer in a distributed system

The physical address of a location in main memory

The address assigned to a location in virtual memory, making it accessible as if it were part of main memory

The location of CPU registers in the memory hierarchy
