Is networking difficult?
Like many things learning basic networking is fairly straightforward but gaining breadth and depth takes a lot of time and dedication. In contrast the person building and operating the network needs to understand in some depth the operation and configuration of the devices that will be connected.
What is network protocol with example?

What is a LAN device?
A local area network (LAN) is a group of computers and peripheral devices that share a common communications line or wireless link to a server within a distinct geographic area. Ethernet and Wi-Fi are the two primary ways to enable LAN connections.
What is a layer in network protocols?
Protocol Layers. The communication between the nodes in a packet data network must be precisely defined to ensure correct interpretation of the packets by the receiving intermediate and the end systems. The protocols are usually structured together to form a layered design (also known as a “protocol stack”).
What is the hardest part of networking?
