Briefly discuss on real-time scheduling? It is divided into two types. Hard real-time systems are needed to complete a critical task within a guaranteed amount of time. T
Determine the reasons for Poor response time Process busy or High I/O rates or High paging rates
1. A digitized voice channel is made by digitizing a 7 KHz bandwidth analog signal. The signal is to be sampled twice the highest frequency (two samples per hertz) . Assume each sa
Q. Several CPU-scheduling algorithms are parameterized for instance the RR algorithm requires a parameter to indicate the time slice. Multilevel response queues require parameters
Short term scheduling The short term scheduler as well known as the dispatcher executes most frequently and makes the fine grained decision of which process to execute next. Th
