A computer network (LAN or WAN) operates by connecting computers and the peripherals (like printers and scanners) using two pieces of equipment: switches and routers. The switches enable the devices in a local network to talk to each other, while the routers enable the devices to connect with external networks.
A switch acts as a controller - it manages how various devices within a local network share information among themselves. The router acts as a dispatcher - it chooses the best route for sending and receiving information across a local and an external network or Internet. Routing and switching functions are all about planning and fixing routers and switches in a network.
The course teaches students the basics of networking and how to configure a small network with routers and switches. It teaches the difference between protocols like IP, TCP and UDP; between IPv4 and IPv6. It also teaches how to configure routers and switches in a network adhering to protocols. The course also covers many related subjects in LAN/WAN networking.
There are plenty of job opportunities for students in the networking space. All organized sectors, right from corporates to small organizations using computer networks, need experts in routing and switching. Some of the popular job titles are: Networking Engineer, Networks Administrator, Network Architect, Network Manager, Networking Support Engineer, and Technical Specialist - Routing & Switching.
