Lesson 05

Evidencing P1 / P2

Session Objectives


Understand the requirements of assessment tasks P1 and P2
for this unit,


Understand what evidence is required to meet P1 and P2.

P1 Requirements


P1 requires you to describe the different types of network
available and the technologies, standards and protocols which
support each,


You will need to focus on the three types of network: WAN,
LAN and PAN.


These are the supporting technologies / standards / protocols
which could be utilised by each type of network:


Technologies
e.g. frame relay, MPLS, ATM; logical and physical
topologies e.g. star, bus, ring, mesh, tree; network access methods
eg

Ethernet, CSMA, Token passing; network models e.g. OSI 7 layer,
TCP/IP


Network protocols and standards:
types e.g. TCP/IP, AppleTalk,
UDP, 802.2, 802.3, FDDI, 802.5; wireless technologies e.g. 802.11,
infrared, Bluetooth, 3G; factors affecting range and speed of wireless
technologies





P2 Requirements


P2 requires you to describe why different network standards
are necessary,


This will normally be covered whilst completing work for P1
however its needs to be overt,


Ensuring these questions are answered during P1 will ensure
the content is properly covered:


Why is TCP/IP used on this and any network instead of another
protocol suite?


The benefit of the WAN standard,


The benefit of the LAN standard,


What protocols are used on WAN?


What protocols are used on LAN?


Evidence


Evidence for P1 / P2 will probably by a report. This essay
structure may help:


Title:

Types of Network and The Technologies, Standards and Protocols Which
Support Them


Para1:

What Is A Computer Network


Para2:

Types of Network and Supporting Techs, Stands, Protocols





Para3:

Notes on TCP/IP


Why used instead of IPX/SPX, AppleTalk


Para4:

Notes of application layer protocols


why we need them / how used


Para5: Diagram showing the use of different network types, technologies,
standards and protocols in real life.

State why each different
technology, standard, protocol
is needed

Programming Constructs


For P1, describing networks, protocols and standards, learners could produce a
report using diagrams.


For P2, learners should be able to demonstrate they understand why different
network standards and protocols are necessary. Examples given should be realistic.
This can be linked to P1.

P1



Describe the types of network available and how they relate to
particular network standards and protocols

P2



Describe why different network standards and protocols are
necessary
