A clustered system gathers together multiple CPUs to accomplish computational work.

The following command will display the first 10 lines of "log.txt":

The CPU can load instructions only from memory, so any programs must first be loaded into memory to run.

Either hardware or software may trigger interrupts.

Processes waiting for a certain event are placed in a ready queue.

One of the actual contributions of Unix (and later Linux) has been the view that "everything is a file."

Contemporary computer systems allow multiple programs to be loaded into memory and executed concurrently.

The one-to-one model maps many user-level threads to one kernel thread.

The base and limit registers used in fixed and variable partition systems are sufficient to implement a full paging system.

The CPU scheduler refers to the number of processes in memory.
