Thursday, June 25, 2009. Of the computer is also known as RAM, standing for Random Access Memory. It is constructed from integrated circuits and needs to have electrical power in order to maintain its information. When power is lost, the information is lost too! A memory device, such as a floppy disk, a hard disk, or a removable cartridge, that is covered with a magnetic coating on which digital information is stored in the form of microscopically small, magnetized needles. Has been used for. Mode bit ad...

Thursday, August 20, 2009. Recovery or Deadlock Recovery. Abort all deadlock processes. And release resource - too drastic. Will lead to loss of work. Abort one process at a time. Releasing resources until no deadlock. How do we determine which process to abort first? Process which has done least work. Processes from a previous checkpoint. Ie before it claimed any resources. Difficult to achieve - sometimes impossible. Complex decisions due to the large number of processes present within a system. Resour...

Thursday, August 20, 2009. No Preemption –. If a process that is holding some resources requests another resource that cannot be immediately allocated to it, then all resources currently being held are released. Preempted resources are added to the list of resources for which the process is waiting. Process will be restarted only when it can regain its old resources, as well as the new ones that it is requesting. Deadlock prevention - low device utilization and reduced system throughput.

Friday, August 28, 2009. Resource Type w/ 4 inst. Pi requests instance of Rj. Pi is holding an instance of Rj. How would you know if there's a DEADLOCK based on the resource allocation graph? If graph contains no cycles. If graph contains a cycle. If only one instance per resource type, then deadlock (meaning if the cycle goes on a single path, it will result to a DEALOCK). Thursday, August 27, 2009. Unsafe State in Resource-Allocation Graph. 183; The RAG above is compose of 2 resources and 2 processes.
