The subject will introduce the basics of computer networks to students through a study of layered models of computer networks and applications. The first half of the subject deals with data communication protocols in the lower layers of OSI and TCP/IP reference models. The students will be exposed to the working of various fundamental networking technologies such as wireless, LAN, RFID and sensor networks. The second half of the subject deals with the upper layers of the TCP/IP reference model through a study of several Internet applications.
Topics covered include: Introduction to Internet, OSI reference model layers, protocols and services, data transmission basics, interface standards, network topologies, data link protocols, message routing, LANs, WANs, TCP/IP suite, detailed study of common network applications (e.g., email, news, FTP, Web), network management, and current and future developments in network hardware and protocols.

- Explain the salient aspects of network technologies and applications
- Be able to use correct terminology within the domain of computer networks
- Be able to conceptualise and explain the functionality of the different layers within a network architecture
- Be able to explain the architecture and operation of the Internet
On completing this subject, students should have the following skills:
- Be able to undertake problem identification, formulation and solution
- Have a capacity for independent critical thought, rational inquiry and self-directed learning
- Have a profound respect for truth and intellectual integrity, and for the ethics of scholarship.
