Under what circumstances would a user be better off using a time-sharing system, rather than a personal computer or single-user workstation?
When there are some other users, the task is large, and the hardware is fast, timesharing makes sense. The full power of the system can be brought to bear on the user's problem. The problem can be solved faster than on a personal computer. Another case occurs when lots of other users require resources at the similar time.
A personal computer is best when the job is small sufficient to be executed reasonably on it and when performance is sufficient to implement the program to the user's satisfaction.

Suppose a logical address space is 1KB, and the page-size is 16 bytes. Assume no page is in the main memory for this process initially and the pure demand paging is used. Current f
about error detection in operating system and how does it take place?
1. On every access, mark the page with a timestamp. Whenever we need to evict a page, we search through memory for the oldest page, the least-recently used page. But we need memory
What is contiguous allocation? Allocation of a group of consecutive sectors for a one file.
Semispace works by maintaining two disjoint areas from which memory can be allocated. These areas are called the from-space and the to-space. At ?rst, the algorithm allocates memor
address binding at load time
Write on short note DMA. Direct M emory Access (DMA) is a technique for transferring data from main to a device without passing it through the CPU. Computers that have
Q. Consider the demand-paged computer system where the level of multiprogramming is currently fixed at four. The system was recently deliberate to determine utilization of CPU and
Q. Present an algorithm for reconstructing a logical ring after a process in the ring fails? Answer: Typically distributed systems utilize a coordinator process that performs
