What is multiprogramming?
Multiprogramming: The management of many processes within a single processor system. Operating systems such like UNIX provide multiprogramming for shared single processor systems. In the single-processor multiprogramming system processes are interleaved in time to yield the appearance of simultaneous implementation. It is the essential theme of modern operating systems
The introduction of multiprogramming brought concerning the ability to share resources among users. Sharing engrosses not only the processor but also the following
In a multiprogramming environment guard of main memory is essential. The concern isn't only the security but as well the correct functioning of the various processes that are active if one process is able to inadvertently write into the memory space of another process then the latter process may not execute properly.
Effects of ultiprogramming on resource utilization Multiprogramming
Processor use 33%
Memory use 67%
Disk use 67%
Printer use 67%
Elapsed time 15 min
Throughput time 12 jobs/hr
Mean response time 10 min
Deadlock Avoidance It's a method to evade deadlock by careful resource scheduling. This approach to the deadlock problem foresees deadlock before it actually occurs. This a
how response times are reduced by allowing time sharing on top of multiprogramming
Explain segmentation hardware? We define an completion to map two-dimensional user-defined addresses into one-dimensional physical addresses. This mapping is affected by means
Convert the following from hex to binary and draw it on the memory map. RAM = 0000 -> 00FF EPROM = FF00 -> FFFF Answer: 0000 0000 0000 0000 (0) RAM sta

Q. Why is it important to scale up system bus and device speeds as the CPU speed increases? Answer: Consider a system which carries out 50% I/O and 50% computes. Doubling-up
Explain bounded buffer and unbounded buffer. Here in a producer-consumer problem the producer process produces information that is consumed by a consumer process. At this time
A friend has promised to log in at a particular time. However, he needs to be contacted as soon as he logs in. The shell script checks after every minute whether he has logged in o
Q. Presume that the following processes arrive for execution at the times indicated. Every process will run the listed amount of time. In responding the questions use non pre-empti
