People use the Internet every day, but often do so without giving it a single thought. As such, it's not uncommon for Internet users to be unsure about how their network works or what devices carry out what functions.
A common point of confusion is the difference between routers and modems. Though many people think they are the same thing, they are in fact different devices that operate differently from one another. The modem is what connects your home to the Internet, while the router is the basis for the network within your home. Knowing the differences between these two devices can be a big help next time you have a power courage or run into internet troubles. This blog will discuss the differences between modems and routers in greater detail.
To begin, let’s look at the three main differences between routers and modems. For one, modems bring the Internet to your home, while routers bring the Internet to your devices. Second, modems have a public IP address, and routers assign local IP addresses. Finally, modems use a WAN (wide area network) network, while routers create a LAN (local area network) network.
The modem connects your home to your Internet service provider (ISP), typically via a coaxial cable connection. Once connected, the modem receives signals from your ISP and converts them into signals your local devices can use. It also takes signals from your local devices and sends them to the ISP. This connection between your home and the Internet is known as a wide area network. Each modem is assigned a public IP address that serves as an identifier for the network on the Internet.
A router, adversely, connects your devices to each other. In hard-wired setups, the router also connects your devices to the modem. These devices are connected either by an Ethernet cable or a WiFi signal. Routers create a local area network within the home, allowing your devices to share files and peripheral devices. The router manages all the information traveling to and from each device and the modem, all while making sure the information is routed (hence the name router) to the correct destination. That said, a router does not require connection to a modem to function. Instead, you can create a local area network without internet access. Simply put, the router carries out four functions: it assigns a local IP address to each device on the network, creates a firewall to prevent security breaches, manages the traffic on your network, and handles parental control preferences.
Think of your modem as a translator, while the router is more like a traffic director. Though the two have traditionally been separate devices, new technologies have merged the devices into one powerful machine. Multi-functional devices such as these offer the ability for users to read emails, stream television, and connect with your smart devices, all from a single source. Furthermore, though they are designed with state of the art technology, they are straightforward and simple to use. These devices make setting up and running your home network easier than ever before.
