using very large time slices (quantas) degeneratesinto First-Come First served (FCFS) algorithm.

using extremely small time slices improves performance .

using very small time slices degenerates into Last-In First-Out (LIFO) algorithm

using medium sizedtime slices leads to shortest Requesttime First (SRTF) algorithm

is part of the operating system paging algorithm

is useless when swapping is used

is the hardware necessary to implement paging

storage pagesat a specific location on disk

always Occurs on large computers.

is a natural consequenceofvirtual memory systems.

can always be avoided by swapping.

can be caused by poor pagingalgorithms.

Batch system

Quick response system

Real time system

Time sharing system

is a hardware memory device which denotesthe location of the currentinstruction being executed.

is a group ofelectrical ckt, that performsthe intent of instructions fetched from memory.

contains the address of the memorylocation that is to be read from or stored into

contains a copy of the designated memory location specified by the MARafter a "read” or the new contents of the memory prior to a "write".

line printer used to print the output of a number of jobs.

terminal used to enter input data to a running program.

secondary storage devicein a virtual memory system.

graphic display device.

helps avoid unnecessary writes on a paging device

helps maintain LRU information

allows only read on a page

none of these

allows it to be completed successfully

allowsit to continue executing late

preparesit for finishing

occurs only whenthereis an errorinit

allows anyone to decodethe transmission

allows only the correct sender to decodethe data

allows only the correct receiver to decode the data

does not encodethe data before transmittingit

requires use of a loader

allows larger programs,but requires more effor

is most used on large computers

is transparent to the user
