Revision Exercise 7 10. What are the key differences
1. Research the concept of context
switching in CPU scheduling. How
FOR ONLINE READING ONLY
can operating systems minimize
context switching to improve the
gaming experience?
2. Operating systems use fairness
and efficiency principles when
scheduling CPU tasks. Discuss
with your classmates the ethical
considerations of prioritizing
certain processes (e.g., emergency
services applications) over others.
How can we balance fairness with
efficiency in CPU scheduling?
3. How does CPU scheduling affect
app responsiveness and patience?
4. How can you optimise the
performance of a smartphone using
CPU scheduling knowledge?
5. How does CPU scheduling promote
collaboration and sharing of
computer resources?
6. How does CPU scheduling
connect to coding and resource
management?
7. How can the knowledge of
CPU scheduling prepare you for
emerging technologies?
8. Provide two real-world cases of
deadlock. For each case briefly
explain its causes and ways to
handle the deadlock. How does the
OS handle process synchronization
to avoid race conditions?
9. How does the OS use CPU
scheduling to improve efficiency?

preemptive scheduling?
11. How does the OS ensure data
security and integrity on storage
devices?
12. What mechanisms does the OS
use to detect and recover from
deadlocks?
13. Imagine that you are a team
developing a new mobile operating
system for educational tablets.
Discuss and answer the following
questions:
(a) Who are the primary users
of this tablet OS (students,
teachers, both)? What are their
specific needs and priorities?
(b) How will you ensure the
security and privacy of student
data stored on the tablets?
(c) How can the OS handle multiple
apps running simultaneously
while maintaining efficient
usage of computer resources
such as CPU and memory?
(d) Design a user-friendly and
intuitive interface suitable for
users of different ages and tech
experience levels. Sketch your
ideas or create a simple mock-
up.
(e) How can the OS be designed
to adapt to future technological
advancements and integrate
with emerging learning
technologies?
