There are approximately 2700 1024-byte blocks of data, so scanning from the disk would require about 27 seconds.A flash game created by, is one of those games you could easily dismiss before even launching it. Manuscript could be scanned in 2.8 msec from the registers or 5.8 msec from Is too big for a 1-MB cache, but if such hardware were available, the

It does not matter atĪll how many stages the pipeline has. Machine is executing 1 billion instructions per second. Every nanosecond one instruction emerges from the pipeline. If all three are on the same CPU, it will take 35 msec.ĩ. If P1 and P2 are scheduledon the same CPU and P0 is scheduled on the other CPU, it will take 30 msec.

No matter how much I/O a program does, theĬPU will be 100% busy. If there is no DMA, the CPU is fully occupied doing I/O, so there is nothing to be gained (at least in terms of CPU utilization) by multiprogramming. The prime reason for multiprogramming is to give the CPU something to do Input spooling ona personal computer is notģ. Output spooling consists of firstĬopying printable files to disk before printing them, rather than printing directly as the output is generated. Onto the disk, so that when the currently executing processes are finished, Input spooling is the technique of reading in jobs, for example, from cards, It is commonly used to keep the CPU busy whileone orĢ. Multiprogramming is the rapid switching of the CPU between multiple processes in memory.
