This guide explores essential networking devices, including routers, network interface cards (NICs), Category 6 cables, patch panels, and switches. Routers forward packets based on internal routing tables, while NICs connect computers to networks. Category 6 cables support Gigabit Ethernet with stringent specifications for performance. Patch panels facilitate cable connections for monitoring and testing. Switches operate at the Data Link Layer, routing data efficiently. A brief overview of drop boxes and raceways is also included, highlighting their roles in modern networking.

Router • A network device that forwards packets from one network to another. Based on internal routing tables, routers read each incoming packet and decide how to forward it. The destination address in the packets determines which line outgoing packets are directed to.
Network Interface Card • NIC is an adapter circuit board installed in a computer to provide a physical connection to a network.
Category 6 Cable • Cat-6 is a cable standard for Gigabit Ethernet and other network protocols that is backward compatible with the Category 5/5e and Category 3 cable standards. Cat-6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T / 100BASE-TX and 1000BASE-T / 1000BASE-TX (Gigabit Ethernet).
Patch Panel • A patch panel is typically rackmounted, and houses cable connections. One shorter patch cable will plug into the front side, whereas the back holds the connection of a much longer and more permanent cable. The assembly of hardware is arranged so that a number of circuits, usually of the same or similar type, appear on jacks for monitoring, interconnecting, and testing circuits.
Drop Box and Race Way • A drop box allows enables users to store and sync files online and between computers • A raceway is a partially-enclosed electrical conduit covering surface-mounted wiring. It can be made of metal or plastic, or even clay and it provides excellent protection from moisture.
Switch • A switch is a network bridge that processes and routes data at the Data link layer of the OSI model. Switches that additionally process data at the Network layer are often referred to as Layer 3 switches or Multilayer switches.
