The first step in networking is to understand the way in which a network operates and the components used to connect two or more devices to the network. This connection is enabled by Routers and Switches.
This course provides information about fundamentals of Telecommunication, OSI and TCP/IP models, frame structures, protocols used for exchanging information and also about some of the communication issues involved in this process.
After completion of this course, students will have a wide knowledge on telecommunication network and troubleshooting methodologies to overcome communication issues.
