running even when not actively
using them.
(c) Describe how demanding

applications (Such as, games or
video editing software) affect
overall system performance.
Step 4: Research and
documentation:
(a) Use the internet to:
(i) Research different types of
processes (system processes,
background processes) and
their functions.
(ii) Explore online resources or
documentation related to Task
Manager, Activity Monitor,
or System Monitor for more
advanced information.
Deliverables:
Produce a one-page report covering
all the aspects mentioned above about
process management and its role
in monitoring system performance.
Relate this to the previous discussion
on process creation and scheduling
within the OS. Ensure your report is
well-organised, clear, and concise.
Keep your report in a portfolio
Note: If a personal computer is not
available, perform the above activity
using a smartphone or tablet and the
appropriate system monitoring tools
available on those devices.
