STRAND 2.0: COMPUTER NETWORKING

Sub Strand: 2.1 Data Communication

Specific Learning Outcomes

By the end of the sub strand, the learner should be able to:

a) explain the terminologies used in data communication,

b) describe the characteristics of data communication systems in computer networking,

c) connect computer devices to create a data communication system,

d) acknowledge the significance of data communication systems in networking.

Suggested Learning Experiences

The learner is guided to:

• use print or digital media to search for definitions of the terms used in data communication (data, signals, communication channel, network, transmission media, TCP/IP, Open System Interconnection (OSI) model, protocols),
• discuss the characteristics of data communication,
• watch a video on how computer devices are connected to create a data communication system,
• create a simulation to show interaction among data communication components (sender, message, medium, protocol, receiver),
• brainstorm the meaning of the terms (data transmission, Analog signals, digital signal data rate, baud rate, bandwidth),
• illustrate data communication modes (simplex, half-duplex, full-duplex),
• debate the advantages and disadvantages of data communication modes,
• sensitise peers on the significance of data communication systems in networking.

Suggested Key Inquiry Question(s)

1. How is data communicated in computer networking?
