Problem:
(a) Modern operating systems are interrupt driven. If there are no processes to execute, no I/O devices to service, and no users to whom to respond, an operating system will sit quietly, waiting for an interrupt or a trap.
What is the difference between an interrupt and a trap?
(b) What is the role of interrupt service routines and how are they related to the interrupt vector?
(c) Figure shows an interrupt time line for a single process doing output. Explain how this operation is being performed.
(d) The figure (a) and figure (b) show two different ways to deal with I/O (Input or Output) requests. When a user process is requesting I/O, two courses of action are possible, synchronous I/O or asynchronous I/O. Describe each flow of action using the figures below, in the context of I/O interrupts.
Q. Explain the actions taken by a kernel to context switch between kernel level threads. Answer: Context switching among kernel threads classically requires saving the value

Q. Suppose that you want to utilize a paging algorithm that requires a reference bit (such as second-chance replacement or working-set model) however the hardware does not provide
Hierarchical paging Single way is to use a two-level paging algorithm, in which the page table itself is also paged. A logical address is separated into a page number and a pag
Question 1 Brief the following distributed computing system model Question 2 Explain the components involved in implementation of RPC mechanism Question 3 What is
Hashed page table method A general approach for managing address spaces larger than 32 bits is to use a hashed page table with the hash values being the virtual-page number.
Define multithreading The proficiency of an operating system to execute different parts of a program called threads simultaneously is called as multithreading. A thread is a fl
Define Segmentation The memory allocation method subject to “external” fragmentation is Segmentation.
Explain internal fragmentation The Internal fragmentation signifies to the result of reserving a piece of space without ever intending to use it. This space is wasted that this
