How Data Communication Works
Free data communication fundamentals
A free Alison course exploring the basics of data communication. Covers the fundamentals of layered architecture (including the OSI model and layers/interfaces), data communication circuits, measuring the capacity of communication media, serial and parallel data transmission, network topologies and classification, peer-to-peer vs client-server networks, and converting data into signals including amplitude modulation.
