Networking Protocols and Concepts Quiz

LAN = Limited to small areas Wi-Fi = Based on IEEE 802.11 standards for wireless local area networking Cellular networks = Enable wireless communication over large areas using cells and mobile technologies Guided media vs unguided media = Guided media uses physical cables, while unguided media refers to wireless communication methods

Store-and-forward communication = Involves temporarily storing data before forwarding it in packet-switching networks Communication delays = Affected by factors like propagation, transmission, and processing delays Packet switching vs circuit switching = The Internet was designed for efficient data transmission, favoring packet switching over circuit switching Routing vs forwarding = Routing determines the path over a network, while forwarding is the process of moving packets along this path
