1. Evaluate networks and networking approaches 1. discuss the role of networks within different organizations and the resource implications of networks 2. discuss the different distributed computing approaches of peer-to-peer and client-server networks 3. explain the functions of client and server computers on a network and give at least one example of interactions between a client and server computer 4. describe the advantages of client-server approaches particularly over centralized services 2. Investigate basic hardware components and the role of network operating system NOS) software 1. draw and describe basic network topologies and define basic network components 2. discuss role of software and hardware 3. discuss factors influencing choice of networks stating advantages and disadvantages that arise from different topologies 4. determine a suitable network for a given site 3. Explore the connection of network components 1. explain different connection materials including their specifications and list the criteria you would use to choose such materials 2. describe basic signaling methods and their characteristics 3. explain the role of the network interface card and carry-out selection, installation and configuration of a network interface card using NOS tools 4. identify how the relevant parameters and protocols are set 5. discuss factors that affect the performance of network interface cards 6. determine a cabling and hardware connection configuration for a given site 4. Explain the Open Systems Interconnection (OSI) model and common network architectures 1. present the OSI layered model 2. explain the role of drivers in a network, discussing their relationship to the NOS and OSI model 3. discuss how drivers are selected and implemented for various network components; install NIC driver and demonstrate how to remove and update 4. explain the detailed operation of different IEEE 802.N network configurations 5. refer the 802 protocols to the existing OSI layers 6. relate how architecture influences access and control of the network and draw out merits of different architectures 7. describe scenarios where one architecture might be favored over another 5. Evaluate data transmission and protocols in a network environment 1. discuss the role of packets and how they are built up from their various components, giving an example where data packets are transmitted through different layers of the OSI model 2. discuss the role of protocols at different layers of the OSI model, describing the function of specific protocols 3. explain examples of transmission between different network layers The Course Work consists of THREE Laboratory Investigations (Labs) plus ONE Case Study. The brief for each Laboratory Investigation is given on an individual work sheet. The completing of each task and investigation must be recorded in a Virtual Log Book.
