Five batch jobs A through E, arrive at a computer center
at almost the same time. They have
estimated running times of 10, 6. 2, 4.
and 8 minutes.
Their (externally determined) priorities are 3, 5. 2, 1 . and
4, respectively, with 5 being the highest priority. For each of the following scheduling algorithms,
determine the mean process turnaround time.
Ignore process switching overhead.
o
Round robin.
o
Priority
scheduling.
o
First-come,
first-served (run in order 10, 6. 2, 4,8).
o
Shortest job
first.
·
For (a), assume
that the system is multiprogramrned, and that each job gets its fair share of
the CPU.. For (b) through (d) assume that
only one job at a time runs, until it finishes. All
jobs are completely CPU bound
- Five jobs are waiting to be run. Their expected run times are 9,6, 3, 5, and X. In what order should they be run to minimize average response time? (Your answer will depend on X.)

fast food restaurant has four kinds of
employees: (1) order
takers, who take customer's orders; (2) cooks, who prepare the food; (3)
packaging specialists, who stuff the food into bags; and (4) cashiers,
who
give the bags to customers and take
their money. Each employee can be
regarded as a communicating sequential process. What form of
inter-process communication do they use? Write a solution using Semaphores.
·
The readers and writers problem can be formulated in several ways
with regard to which category of processes can be started when. Carefully
describe three different variations of the problem, each one favoring (or not
favoring) some category of processes. For each variation, specify what happens
when a reader or a writer becomes ready to access the data base, and what happens
when a process is finished using the data base.
