About this subject
This subject introduces data communication basics such as signals, modulation, transmission media and error detection, then moves on to computer networks through the OSI model, LAN standards, routing, and the TCP/IP protocols. After it you will be able to explain how data moves across a network layer by layer, calculate error-check codes, compare routing methods, and work out IP addressing and subnetting.
