For the following questions answer them individually
With Round-Robin CPU scheduling in a time shared system
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.
Whatis the nameof the operating system that reads and reacts in terms of actual time ?
Quick response system
Real time system
Time sharing system
The memory Address Register
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".
An example of spooled deviceis a
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.
Dirty bit for a page in a page table
helps avoid unnecessary writes on a paging device
helps maintain LRU information
allows only read on a page
none of these
.Check pointing a job
allows it to be completed successfully
allowsit to continue executing late
preparesit for finishing
occurs only whenthereis an errorinit
A public key encryption system
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
