Blank Filling ( 10,1 per blank) 1. provides an interface to the services made available by an operating system. 2. increases CPU utilization by organizing jobs (code and data) so that the CPU always has one to execute. 3. When the computer system is executing a system call, the system is in 4. When IO or relevant event completion, the process state will switch from to state. 5. High overhead will be produced when moving bulk data such as disk I/O. In this case, is used. 6. The scheduling can remove process from memory and later reintroduce into memory to continue its execution. 7. Deadlocks can be described precisely by a directed graph called a 8. Under the normal of operation, a process may utilize a resource in the sequence as request, use and 9. A solution to the critical section problem must satisfy the requirements of mutual exclusion, , and bounded waiting
