Difference Between Modem and Router

Modem and router are terms used interchangeably. However, there is a big difference between modem and router. It is quite easy to mix up between the two devices, if you do not know the simple difference between them.

Let us help you understand the difference between a router and modem in this article.

What is a Modem?

The modem is the device that helps connect a cable from outside and bring Internet connectivity to your computer. It connects the Internet Service Provider (ISP) through an Ethernet cable or DSL Internet service. The modem helps in facilitating the Internet connection by transmission and receiving data over telephone line. It usually has two ports. One port connects to the ISP and the other connects to the router in case of larger network.

Usually modems were standalone devices. They could be connected to the computer directly or to a router. Without the modem, Internet cannot be transmitted to your computers.

What is a Router?

A router is a device that helps you connect to the modem and build a private network. This network could be your home network, office network, or a network in a place of business such as a hotel. A router helps connect your devices to the Wi-Fi and bring internet not just to your computer, but even your smartphones, tablets, laptops, etc. wireless routers helps stream content on your devices.

Initially routers just had Ethernet ports for wired connections. However, the latest models now provide wireless connectivity. The router helps one access the LAN, but not necessarily access the Internet. To be connected to the Internet, the router needs to be connected to a modem. Thus, routers have a specific Ethernet port that is designed for connection to the Ethernet cable or DSL modem.

As you can see, the router and modem are two separate entities. Both need each other’s to help you access the Internet wirelessly. You can even find modems that have integrated routers today. These combo devices can be purchased from the market or can be supplied by the ISP provider.

So, the biggest difference between modem and router is that the modem can connect only one device to the Internet and the router can help multiple devices connect simultaneously to the Internet.  A modem provides Internet connection and a router cannot provide Internet connection without the modem.
