A worked IT 110 Unit 3 scheduling algorithm exercise: one arrival set run under each policy, occupancy charted, waiting and turnaround computed per process, averages compared. Searches like "it 110 unit 3 assignment example", "it110 unit 3 sample" and "it 110 unit 3 example" land here.
What a finished IT 110 Unit 3 scheduling algorithm exercise looks like
The artifact is a worked problem set rather than an essay. A heading block restates the process list exactly as the assignment gave it, arrival time and burst length per process, and declares the tie-breaking rule in force when two processes become ready at the same instant. Each policy then gets its own block: a horizontal occupancy chart marked at every instant the processor changes hands, a per-process table giving completion, turnaround and waiting figures, and a line of arithmetic showing how each waiting figure was obtained rather than only what it came to. Where a policy needs a parameter, the value used is stated and defended in a clause. A comparison table closes the set, averaging each measure and naming which policy won it and which process paid.
How a IT 110 Unit 3 example is structured
The process list and the tie-breaking rule are fixed once at the top because every block below runs the same input, and a set that restates arrivals per policy invites a quiet edit that leaves two blocks incomparable. Occupancy is charted before any figure is computed, since completion times are read off the chart and a table built without one is a table built from memory. Arithmetic sits under each figure instead of being collected below the tables, since partial credit is awarded exactly where a subtraction goes wrong halfway down a column. Policies run from the simplest rule to the most conditional, so each block adds one idea to the one before it. The comparison closes the set, because averages mean something only once every policy has been run on identical input.
Arrivals and bursts fixed once
The process list is stated at the top and never restated, so every policy below is demonstrably running on identical input.
The tie-breaking rule declared openly
What happens when two processes become ready in the same instant is settled in advance, because that choice moves several later figures.
Occupancy charted before any table
A marked chart shows who held the processor across each interval, and the completion times in the table are read from it.
Waiting shown as arithmetic
Each figure carries the subtraction that produced it, which is where partial credit lives when one line of the working slips.
Parameters stated and defended
Any value a policy needs is named with a clause saying why it was chosen, since an unexplained parameter makes the block unarguable.
Averages compared on identical input
A closing table sets each measure side by side and says which policy won it and which process carried the cost.
Where marks go in IT 110 Unit 3
Answer columns cost this exercise the most. Averages reported with no chart and no subtraction under them satisfy nothing in a rubric asking for demonstrated method, and a set carrying one arithmetic slip with full working usually scores higher. Turnaround and waiting exchanged produce two internally consistent tables that are both wrong. Starting every policy at zero when the list has staggered arrivals is the error that survives proofreading, because the chart still looks tidy. Ties resolved one way in one block and another way in the next make the comparison meaningless without anybody noticing. Declaring a policy best in general overstates a result taken from one input set. Prose recommending what a reader should configure on a machine has left the exercise for administration, which this unit did not set.

The custom example charts occupancy under each policy, computes completion, turnaround and waiting with the arithmetic visible, and closes on an averaged comparison naming who paid for the win.

IT 110 Unit 3 questions, answered
Can I use a scheduling simulator to get the answers?
Run one as a second opinion, never as the submission. This unit grades the chart and the subtraction beneath each figure, so averages arriving with no chart and no working behind them read as something a program decided. Work the policies by hand first and then let a simulator disagree with you, because a disagreement usually exposes a tie you resolved without noticing.
Which policies does the exercise have to cover?
Whichever ones the assignment lists. If that decision falls to you, pick policies that genuinely disagree on the same input rather than three variations of one idea. A preemptive rule set beside a non-preemptive one gives the comparison table something to show, while three similar rules produce three near-identical charts and leave the criterion about trade-offs untouched.
Does the exercise need real timings from a machine?
No, and collecting them would answer a different question. Scheduling problems here are arithmetic on a supplied list, while timings taken off a working system include everything else that system happened to be doing. If you want one sentence connecting the exercise to practice, say what your figures would miss on a busy machine rather than substituting one for the other.
