The internet, like the telephone system which preceded it, depends for its existence on communications networks. This free course, Protocols in multi-service networks, examines these networks as the means of interconnecting devices so that two-way communication is possible. Examining protocols like HTTP, TCP/IP and ATM as well as the OSI reference model, it provides an overview of the topic for learners who have significant prior knowledge of the subject.
Course learning outcomes
After studying this course, you should be able to:
evaluate technical descriptions of communication protocols and demonstrate an understanding of their operation
describe the characteristics of circuit-switched and packet-switched networks, and of connectionless and connection-oriented modes in packet-switched networks
describe the role played by primitives in the OSI reference model
explain how ‘vertical’ and ‘horizontal’ communication takes place in the OSI reference model
describe the main functions of the principal protocols in the TCP/IP architecture.
