In today?s connected world, phones, PDAs, computers, .. all share information. In reality, it?s the applications running on these devices, e.g. picture messaging and e-Commerce, that share the information. This course unit examines the principles involved in making this sharing possible, efficient and secure. In particular, it looks at how networking can mask many of the imperfections of interconnection technologies from applications; allow applications to share communication mediums; and potentially give Quality of Service (QoS) guarantees to applications. At the end of the unit you?ll appreciate how different applications can place different demands on the interconnection infrastructure and conversely how technology can limit the types of application that can be run.


Computer networks have become an essential tool enabling users to obtain information and to co-operate on applications. This course unit aims to give an understanding of the principles of data communication and computer networks. It will cover the principle of network protocols, structures, standard and services mainly concentrating on wired networks but with a mention of wireless in places.
