Provide two programming examples of multithreading giving improved performance over a single-threaded solution.
(1) A Web server that services every request in a separate thread.
(2) A parallelized application such as matrix multiplication where dissimilar parts of the matrix may be worked on in parallel.
(3) An interactive GUI program like a debugger where a thread is used to monitor user input, another thread shows the running application, and a third thread monitors performance.
Symmetric multiprocessing To get maximum reliability and efficiency a mode of function called as symmetric multiprocessing is used. In essence, with SMP any program or threads
SSTF (Shortest Seek Time First) After a demand go to the closest request in the work queue regardless of direction Decrease total seek time compared to FCFS Disadv

Identifying parallelism A formal way to identify parallelism in an activity is to draw a task dependence graph in a directed graph in which each vertex represents a task to
properies of Batch oriented and interactive operating system.
1. What must a kernel provide for an effective user-level thread implementation? 2. With respect to the quantum q in a scheduling algorithm, explain and discuss the impact of the
Multi-level page tables are tree-like structures to hold page tables. As an example, consider a two- level page table, again on a 32-bit architecture with 212 = 4 kbyte pages. Now,
Define secondary memory. This memory holds those pages that are not there in main memory. The secondary memory is usually a high speed disk. It is called as the swap device, an
