Belady's Anomaly
A counterintuitive effect in which increasing the number of page frames may increase the number of page faults.
3 CPU bound
A property of a process in which processor use is high, and I/O requests are low.
4 Circular
LOOK disk scheduling A disk scheduling strategy which satisfies the pending disk request which is physically closest to the current position of the access arm in the direction toward the inside of the disk, reversing direction and seeking to the outside when it reaches the cylinder of the innermost request, and repeating.
5 Circular SCAN disk scheduling
A disk scheduling strategy which satisfies the pending disk request which is physically closest to the current position of the access arm in the direction toward the inside of the disk, reversing direction and seeking to the outside when it reaches the innermost cylinder, and repeating.
6 DRAM
Semiconductor read-write memory in which individual bit cells must be peridically refreshed.
7 Direct Memory Access
The transfer of data between memory and a peripheral directly, without passing through the CPU.
8 EBCDIC
