What is the difference between a modem and a router?

 

A modem is a device that connects your home network to the internet. It converts signals from your internet service provider (ISP) into signals that your devices 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 share files and resources.

Here is an illustration of the difference between a modem and a router:

Here is a table that summarizes the key differences between a modem and a router:

Feature	Modem	Router
Connects to	ISP	Local devices
Converts signals	Yes	No
Creates a LAN	No	Yes
Allows multiple devices to connect to the internet	No	Yes
Shares files and resources	No	Yes

To access the internet, you need both a modem and a router. The modem will connect your home network to the internet, and the router will distribute the internet connection to your devices.

Here is an example of how a modem and router work together:

1. Your ISP sends a signal to your modem.
2. The modem converts the signal into a format that your devices can understand.
3. The modem sends the signal to your router.
4. The router distributes the signal to your devices.

Your devices can then access the internet.
