Question

1. Under UNIX, the operating system schedules processes by responding to user commands.
2. UNIX relies on roll-in and roll-out techniques to manage memory space.
3. The swapping process is part of the kernel and thus can be activated each time UNIX gets
control of the processor.
4. The UNIX swap-in decision is based on secondary storage residency time—the longer a
process resides on disk, the lower its priority.
5. To keep track of active text segments, UNIX maintains an i-node table that lists each
current text segment, its primary and secondary addresses, and a count of the number of
processes sharing it.
