1. Introduction to Network Devices All networks are made up of basic hardware building blocks to interconnect network nodes‚ such as Network Interface Cards (NICs)‚ Bridges‚ Hubs‚ Switches‚ and Routers. In addition‚ some method of connecting these building blocks is required‚ usually in the form of galvanic cable (most commonly Category 5 cable). Less common are microwave links (as in IEEE 802.12) or optical cable ("optical fiber"). An ethernet card may also be required. Network interface cards
