Overview Of The Unit
• Fancy That! is a business selling fancy dress
costumes.
• They want to create a website to advertise
their business with a catalogue the

Summary Of P1, M1 and D1
• For P1, learners should compose a brief outline
of the web architecture and components which
allow the internet and websites to function.
• For M1, learners should go into more detail
regarding the way websites move information
for communication. Learners should discuss
current methods of information sharing and
movements such as Web 2.0.
•
•
For D1, learners should give a technical
explanation of application layer protocols in
relation to the TCP/IP protocol.

TOPIC
What Is a Protocol?
• A 'protocol' is a set of invisible
computer rules that govern how data
gets transmitted to your screen.
• In networking they standardise the way
different devices talk to one another –
sometimes known as a handshake.

TOPIC
TCP / IP
• The internet uses a model called TCP/IP
(Transmission Control Protocol / Internet
Protocol), which contains a number of
different sets of rules to control different
types of communication – the rule sets
are known as a protocol suite.
– The TCP part deals with communicating
between applications in your computer – e.g.
web browser to OS to NIC driver,
– The IP part controls communication between
different devices.

TOPIC
TCP/IP Model Layers

Each layer within the model has a different job,



The link layer is the lowest and deals with how the
data will actually be sent through the network
hardware – how the data is transmitted along cables /
fibre, navigates through routers, servers etc
The internet layer packs data into data packets known
as IP datagrams, which contain source and
destination address information that is used to
forward the datagrams between hosts and across
networks. The internet layer is also responsible for
routing of IP datagrams.
The transport layer establishes communication
between the source and destination hosts and
permits them to carry on a conversation

TOPIC
Application Layer
• The application layer is the highest layer within
the TCP/IP and provides protocols which we use,
through the use of software applications,
• You need to be aware of the function of the
following application layer protocols
–
–
–
–
–
–
HTTP,
HTTPS,
SMTP,
POP3,
IMAP,
FTP,



D1 Overview
• D1 Requires you to explain the role of the TCP/IP
protocol and how it links to the application layer,
• The assignment ask you to add a final section to
your report which gives a technical explanation of
TCP/IP application layer protocols used on the
internet,
• You could structure this by having:
– A detailed overview of TCP/IP including
diagrams showing the layers and a detailed
explanation the job of each layer,
– A table which explains technically how each of
the application layer protocols work –
diagrams will help.
