Most modems have three ports: one that connects the device to the internet, another to the power source, and a final one to the router. That is why a modem is also referred to as a modulator-demodulator. It also modulates the digital signals transmitted from your computer into analog signals to allow your computer’s data to be sent over the internet. And that’s where the modem comes in.Ī modem demodulates the incoming analog signals into digital signals so your computer can understand them. To access the internet, you’ll need a device to convert the analog signals you receive from your provider into digital signals that your computer and other digital devices can understand. While the internet transmits analog signals, digital devices such as your phone, computer, and tablet can only decode digital signals. Two main signals are transmitted between devices and the internet: an analog signal and a digital signal. Since gateways and modem routers combine the functionality of a modem and a router, only one device is required to achieve the same result.A signal, in simple terms, is an electromagnetic wave that transmits data from one device to another. When your home network uses a modem-router combination device or a gateway, it talks directly to the Internet Service Provider to connect you to the internet and enable a Wi-Fi connection. A modem will give local Internet access to a single device, but requires a router to connect multiple devices via Wi-Fi. In the traditional home network chain of command, the router talks to the modem which talks to the internet service provider, resulting in an internet connection and Wi-Fi. The primary benefit to using a modem router or gateway is the simplicity of only having a single device to set up. Modems and routers can be combined into a single box, and gateway is another term for a combined modem router. The router’s main function is to create and send out the Internet Wi-Fi signal in your home. RouterĪ router is works with your modem to join networks together and allow multiple devices like phones, tablets and computers to use a single network through a wired or wireless connection. It acts as a digital translator, taking an information signal (Internet data) from your cable or phone lines and making it accessible to your computer. Before we get into the differences between modems, routers, gateways and modem routers, let’s review what each device does.Ī modem is a small box that connects your household to the Internet using cables. Have you ever fallen down the research rabbit hole as you look into all your home networking options?
