operation system
1(TRUE/FALSE) Switching among threads in the same process is more efficient than switching among processes.
2(TRUE/FALSE) The First-come, first-served (FCFS) scheduling is NOT always a good scheduling algorithm for short processes.
3(TRUE/FALSE) A linker loads the executable file into memory, where it becomes eligible to run on an available CPU. A loader combines several relocatable object modules into a single binary executable file.
4(TRUE/FALSE) Deadlock can never occur if no process is allowed to hold a resource while requesting another resource.
5(TRUE/FALSE) To prevent the occurrence of a deadlock, it is sufficient to negate at least one of the four conditions (Mutual Exclusion, Hold and Wait, No Prermption and Circular Wait) that contribute to deadlock
6.(TRUE/FALSE) CPU scheduling is the task of selecting a waiting process from the waiting queue and allocating the CPU to it.
