Which of the following scenarios best describes the use of a base register?
Which of the following scenarios best describes the use of a base register?
- A program requires more memory than physically available, so portions are swapped to disk.
- An operating system switches from running one program to another, saving the state of the first.
- Multiple programs are executed sequentially without user intervention.
- A program's memory addresses are translated from symbolic to physical locations during execution. (correct)
In a multitasking operating system, what is the primary purpose of a context switch?
In a multitasking operating system, what is the primary purpose of a context switch?
- To execute a series of jobs in a predefined sequence.
- To manage the allocation of memory to different processes.
- To translate symbolic addresses to physical addresses.
- To enable multiple processes to share a single CPU. (correct)
Which of the following is the MOST direct purpose of CPU scheduling?
Which of the following is the MOST direct purpose of CPU scheduling?
- Converting logical addresses used by a program into physical memory addresses.
- Deciding which processes should be executed by the CPU and in what order. (correct)
- Managing virtual memory by swapping pages between RAM and disk.
- Determining which applications should be installed on a system.

Study Notes
- Address binding is the mapping of a program's symbolic addresses to physical memory addresses.
- Application software refers to programs designed to help users perform specific tasks like word processing, web browsing or gaming.
- Batch processing describes the execution of a series of jobs on a computer without manual intervention, where tasks are processed in batches
- Base register is a register in the CPU that holds the starting address of the current memory segment, used for address translation.
- Bounds register is a register holding the ending address of a memory segment, thus ensuring memory accesses stay within the allocated range
- Context switch involves storing and restoring the state of a CPU so multiple processes can share a single CPU.
- CPU scheduling is the method by which an operating system decides which processes should be executed by the CPU and in what order.
- Demand paging is a memory management scheme where data pages are brought into memory only when needed, rather than in advance.
- Dumb terminal is a simple display and input device lacking processing power, relying on a central computer for computing tasks.
- Dynamic partition technique pertains to a memory management method where memory is divided into variable-sized partitions based on process needs.
