Consider a system running ten i/o bound tasks and onecpu -bound
task. assume that the i/o bound tasks issue an i/ooperation once for
every millisecond of cpu computing and that eachi/o operation takes
10 milliseconds to complete. also assume thatthe context switching
overhead is 0.1 millisecond and that allprocesses are long running
tasks. what is the cpu utilization for around robind scheduler
when:
a. the time quantum is 1 millisec.
b. the time quantum is 10 millisec.

iphones are still better

solution:

the right option is a

to adding   a new row to a table we   have to do process last table cell and pressing tab.

this is the process to add new row in the cell:

* to add a row below the cell, click insert below in the rows and columns group.

thus this is the required right answer.

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
