BTEC IT Unit 09 - Lesson 05 Evidencing P1 / P2 Mr C Johnston ICT Teacher www.computechedu.co.uk 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? Include within the description benefits and limitations of the network type State why each different technology, standard, protocol is needed 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 Network Types WAN LAN PAN Description Technologies Standards Protocols Table or paragraphs Para3: Notes on TCP/IP – Why used instead of IPX/SPX, AppleTalk WAN Description xxxxxxxxxxxxxxx Technologies xxxxxxxxxxxxxxx Standards xxxxxxxxxxxxxxx Protocols xxxxxxxxxxxxxxx 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. 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 • • 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.
