METHOD OF ASSESMENT:
The FINAL MARK of this subject is arrived at by the combination of the
following:
(i)
(ii)
60 % (Theory)
15 %
15 %
15 %
15 %
Class Test 1
Class Test 2
Class Test 3
Class Test 4
30% (Practical)
15 % Practical Test 1
15 % Practical Test 2
10% (Assignment)
10 % Assignment
Make-up Test (covers entire syllabus)

For students who achieve 45 to 49% determined from the
weighting outlined above provided a minimum of 40% is
achieved for both practical tests.

If a student achieves a mark that is more than 50% in the
make-up test s/he will be allocated a maximum mark of 50%.
This new mark will then replace the lowest mark achieved in
one of the tests written and the corresponding weight used to

calculate his/her final mark.
NOTE:
(i)
A pass will be a final combined total mark of 50 % or more.
(ii)
A total mark of less than the minimum of 50 % will result in a “fail”.
PURPOSE:
The purpose of this course is to build on the subject matter covered in the Subject, Digital
Communications II, which covered the Physical and Data Link Layers. This subject will take the
learner further, covering the Network/ IP layer.
Basic principles will be emphasised and topics of fundamental importance concerning the
technology and architecture of the IP layer for data and computer communications will be
covered.
The subject explores the key topics in the field of data and computer communications, pertaining
to the Network Layer, in the following general categories:

Local Area Networks and Intranets: Addressing, switching, route
discovery, route selection, connection services, gateway services, ISDN
switched connections, Frame relay, High bit rate leased lines and
Metropolitan Area Networks.

Wireless Networks: Introduction to wireless networks, Bluetooth, Radio
interference,
Configuration
and
terminology,
Baseband
packet
transmissions, Baseband packet formats, Error control, Link Manager
protocol and establishing a piconet, L2CAP, Service discovery protocol,
Protocol stack and application profiles, IEEE802.15, Wireless LANS,
Wireless media, MAC sub-layer protocol, Cellular radio networks, Functional
architecture of GSM, GPRS and UMTS.

The Internet Protocol: Introduction, IP datagrams, Fragmentation and
reassembly, IP addresses, Class-based addresses, Sub-netting, Classless
addresses, Network address translation, Routing algorithms, Static routing,
Flooding, Distance vector routing, Link state OSPF routing, Tunnelling,
Broadcast routing, Routing in the Internet, Internet structure and terminology,
ARP and RARP, DHCP, OSPF, BGP, Multicast routing, IGMP, M-bone,
ICMP, Mobile IP, QoS, Integrated services, Differentiated services, MPLS,
IPv6, Datagram format, Address structure, Extension headers, Autoconfiguration, IPv6/IPv4 Interoperability, Dual protocols, Dual stacks and
tunnelling, Translators.

PRACTICAL WORK:
Practicals are based on the CCNA concept using the Cisco Packet Tracer V5.3. As a first level of
learning procedure, to relate theory and practical usages of connectivity, configuration of PC,
Hub, Repeater, Bridge, Switch and Router are given importance.
CONTINUOUS ASSESSMENT AND LEARNING OUTCOMES:
Continuous assessment means that your effort and level of competence is continually
being assessed. Formative assessments are on-going in all lectures, practical and tutorial
classes by means of verbal and written questions, class exercises and tutorial problems. These
assessments are meant to guide you in self-assessing your knowledge and competence. The
tests are both formative and summative assessments.
Use the table below to guide you in understanding what the assessment criteria are and their
relative weighting for this subject.
LEARNING OUTCOME
Comprehension (50%)
Application (20%)
Analysis (30%)
ASSESSMENT CRITERIA
Correct understanding of
written/verbal technical text.
Correct understanding of
technical diagrams.
Best practice construction of
circuits and systems.
Best
practice
written
reporting.
Best practice construction of
technical diagrams.
Best practice method and
correct result of calculation
or determination of technical
details
of
techniques,
circuits and systems.
ASSESSMENT METHODS
Test, tutorial and practical
questions.
Practical exercises.
Practical test questions.
Practical report writing.
Test, tutorial and practical
questions.
Comprehension and analysis are the major components of the expected learning outcomes.
Comprehension involves understanding and integration of information. That is, can you see how
the pieces of information fit together? Can you translate the information into different contexts?
Analysis requires comprehension as a pre-requisite. Analysis is very important in technical fields.
Successful analysis requires careful attention to detail which means checking your facts and
working.
