Most Layer 1 and 2 networking technology falls into one of two primary categories: wide-area networks (WAN) and local area networks (LAN). Because both WANs and LANs match OSI Layers 1 and 2, they have many similarities: Both define cabling details, transmission speeds, encoding, and how to send data over physical links, as well as data-link frames and forwarding logic.
Of course, WANs and LANs have many differences as well, most notably the ...
