Downloaded from: justpaste.it/810xj What is the difference between a router and a modem? post by inovi A modem and a router are two essential devices for connecting your home network to the internet. However, they have different purposes and functions. A modem (modulator-demodulator) is a device that converts the digital signals from your computer into analog signals that can be transmitted over telephone lines or cable. It also converts the analog signals from the internet back into digital signals that your computer can understand. A router is a device that creates a local area network (LAN) in your home. It allows multiple devices to connect to the internet at the same time and also allows them to communicate with each other. Here is a table that summarizes the key differences between a modem and a router: Feature Modem Router Converts digital signals to analog signals and vice versa Connection To the internet IP address Public IP address Network type In most cases, you will need both a modem and a router to connect your home network to the internet. However, some ISPs offer modem/router combos that combine both devices into a single unit.

Wireless routers are the most common type of router and allow you to connect to the internet wirelessly. Wired routers connect to your devices using Ethernet cables. Mesh routers create a wireless mesh network that covers a wider area than a traditional wireless router.
