Week 4

What is the main goal of the long-term scheduler?

• To bring new processes to the 'Ready State'

• To boost system performance by selecting processes for running state

• To manage the long-term execution of processes

• To ensure no starvation due to high burst time processes

Which type of interrupt is generated by external devices and I/O devices?

• External Interrupts

• Software Interrupts

• Hardware Interrupts

• System Interrupts

What is the responsibility of the lower-level scheduler?

• To manage the long-term execution of processes

• To select one process from the ready state for scheduling on the running state

• To boost system performance by selecting processes for running state

• To bring new processes to the 'Ready State'

What is the purpose of a Process Control Block (PCB)?

• To ensure no starvation due to high burst time processes

• To manage the long-term execution of processes

• To bring new processes to the 'Ready State'

• To store all the details regarding the process like its current status and program counter

What is the process of storing the state of a process or thread so that it can be restored and resume execution at a later point?

• Thread Switching

• Process Switching

• State Switching

• Context Switching

Which scheduling algorithm uses the concept of time quantum?

• First-Come, First-Served (FCFS)

• Shortest Job First (SJF)

• Round Robin (RR)

• Priority Scheduling

In a paging system, what is the term for the division of logical memory into blocks of the same size?

• Frames

• Pages

• Segments

• Blocks

What mechanism allows the operating system to provide a user program with a contiguous working memory while being physically fragmented?

• Segmentation

• Paging

• Swapping

• Virtual Memory

How does the operating system detect a page fault?

• By checking the page table for a valid-invalid bit

• Through a specific interrupt generated by the CPU

• By monitoring the access patterns of the program

• Using a special register in the CPU

What is the primary function of the Translation Lookaside Buffer (TLB)?

• To store recently executed instructions

• To enhance disk storage capacity

• To speed up the translation of virtual addresses to physical addresses

• To manage the input/output operations
