Introduction

This section aims to lay the foundation of the course by introducing the basic concepts behind data communications. This includes definitions of bit, baud, binary code and both asynchronous and synchronous transmission.

Interfaces

Introduces the standards and principles behind data interfaces. Includes overviews of physical, electrical and functional interfaces, RJ45 and Optical cable. The concepts of flow control are reviewed.

Analogue Transmission

Reviews the basic analogue transmission methods and media, including PSTN, Digital/Analogue conversion, modem standards and the AT command set.

Digital Transmission

Outlines the features of digital transmission, including the concepts of Pulse Code Modulation, Time Division Multiplexing, the 2.048 Mbit Frame, Plesiochronous Digital Hierarchy (PDH) and Synchronous Digital Hierarchy (SDH)

Communications Protocols

Introduces the features and functions of protocols and how they relate to the OSI 7 layer model.

Local Area Networks

Defines the concept of a Local Area Network and some of the principles involved with LANs. Includes overviews of CSMA/CD, FDDI, Token Ring, Bridges, Switches, and Routers

Packet Technology (X.25)

Outlines the concept of Packet Technology and uses the X.25 protocol as an example. Includes an overview of how Packet Switches operate using  tables to Multiplex Virtual Circuits.

WANs

Reviews development of Wide Area Networking technology and features key protocols used for WAN transmissions -  including ISDN, Frame Relay, ATM and IP.

The Internet

The final section overviews the Internet and in particular IP Addressing, TCP/IP and DNS.
