What is a multiprocessing system?
Multiprocessor systems are those systems that use additional than a single processor for program execution. It is done for raising the execution speed of the entire system. The initiative behind multiprocessing is that a single process can be divided into sections which can be executed singly in different processors. Mainframes and Super computers make use of multiprocessing. Multiprocessing is applied in two ways they are:
a. Parallel processing or tightly coupled systems
b. Loosely coupled systems.
In Tightly coupled systems or Parallel processing systems the resources like memory are shared with different processors. This may decrease the cost for memories but the realistic implementation of tightly coupled systems isn’t so easy.
In loosely coupled systems every processor will be having it own memory and they will be sharing the system bus and I/O etc. Its execution is comparatively easier to parallel processing.
Multitasking - An Operating systems that is proficient of allowing multiple software processes to be run at the same time. Below are some instances of multitasking Operating Syste
What is a pure demand paging? When starting implementation of a process with no pages in memory, the operating system sets the instruction pointer to the first instruction of t
Define seek time and latency time. The time taken by the head to move to the appropriate cylinder or track is known as seek time. Once the head is at right track, it must wait
Consider a large web-based database. In some sense, Google is sort of like this. There might be many users who want to read from the database, but only a few users who are allowed
What is spooling? Spooling overlaps the I/O of single job with the computation of other jobs.
Broken data into small packets allow time division multiplexing. In TDM every packet leaves the sender and is switched on the shared interaction channel through a multiplexer. At t
What is a semaphore? A semaphore 'S' is a synchronization tool which is an integer value that, apart from initialization, is accessed only by two standard atomic operations; w
