Glossary of Terms
Scheduling — The process of deciding what thread should execute next on a particular CPU. It is usually
also taken as involving the context switch to that thread.
Scheduling Latency — The maximum time that a "ready" thread can be delayed by a lower priority
thread.
Scratch Memory — Memory that can be overwritten without loss; i.e., prior contents need not be saved
and restored after each use.
Scratch Register — A register that can be overwritten without loss; i.e., prior contents need not be saved
and restored after each use.
Thread — The program state managed by the operating system that defines a logically independent
sequence of program instructions. This state may be as little as the Program Counter (PC) value
but often includes a large portion of the CPU's register set.
