Communication Fundamentals
In order to understand the basics of data communication following fundamentals are to be studied. Analog and Digital Signals Pulse Code Modulation [PCM] Multiplexing [FDM and TDM] Primary Mux [E1 or T1] High Order Muxes Modulation [Analog and Digital] Transmission Media Characteristics Copper, Fibre and Radio Transmission Satellite and Mobile Communication
Then we have to study, Data Transmission Principles LAN Concepts WAN Concepts Internetworking and Network Devices
For networking many network devices are needed. In order to purchase different devices from different vendors some kind of standard was needed. If the devices are
