Aim and purpose This unit provides the basic knowledge to enable the learner to develop the skills and understanding required to safely install and maintain components in networking. Unit introduction Networking skills are particularly valued in the IT industry and this unit provides a solid foundation for learners to gain knowledge of different types of network and how they are controlled. Learners will investigate the different network topologies, recognise interconnection devices and cabling and how to use them, and look at the advantages and limitations of peer-to-peer and client-server networks. Some time will be spent working with null modems and discovering how networks deal with and prevent data collisions. How to control access to a network will also be considered.
