You can think of this as the gateway from the outside world to your internal network. The modem takes in a signal from your Internet Service Provider (ISP) and allows you to access it.
This is the director of your network, as the name suggests, routing internet signals to many different devices within your internal network. The router manages inside IP Addresses, which are unique strings of numbers that identify various devices within the network. Every device connected to the internet inside your network is assigned an IP Address.
This optional device is set up to monitor and filter traffic from the outside internet to the inside network, aiming to provide a secure experience free from malicious activity. This can be built into another piece of equipment like the router, or separately wired in.
This device plays a critical role in physically distributing internet signal to multiple devices with wired connections. A router often only has 4-8 data connections built into it. In order to connect more devices to your network, a switch (or multiple switches) is required to distribute to 8, 12, 24, or even 48 more devices each. In wired networks, every device needs a dedicated “homerun,” or direct connection back to the router or a switch.
These devices generate the wireless signal we know as “Wifi”, distributing it throughout a property. In well-designed systems, multiple WAPs are strategically placed to provide a seamless transition between different areas of the property. Your personal devices will bounce between WAPs, latching onto whichever one is providing the best connection.

We understand that most people don’t have hidden networking talents, and there can be a lot of lingo thrown around. Here’s a quick summary of how you can expect any basic home or business network to function.
