Networking involves connecting computers to share data and access the internet. A network is likened to a body's central nervous system, with key components like a router (the brain) and a switch (the spine) that distribute signals.
A router acts as the 'brain' of the network, assigning unique IP addresses to each connected device and managing all incoming and outgoing data traffic. It connects to the internet via a modem provided by your internet service provider.
A switch sends data traffic to its intended destinations within the network. Netgear home routers typically have a built-in four-port switch. Wireless routers also have these ports for wired connections. Pay attention to switch speed; gigabit switches are ideal for streaming, while fast ethernet is suitable for basic tasks.
If you need more than four wired connections, you can add an additional switch. These standalone switches, available with various port counts (e.g., 5 to 24 ports), allow you to expand your network without adding another router. Gigabit switches are recommended for faster speeds.
Switches have replaced obsolete hubs because they perform the same function with significantly more speed and intelligence. A router, a switch, and network cables together form a fast and reliable wired network.
