With a modem computer, dial-up Internet access can be performed, and a router is a device that helps multiple computers share a network. Different functionsĪ modem is a necessary device for computer networking. Modem vs router: what’s the difference? 1. If it's a computer, you can access the Internet).
One end of the modem connects to your internet service provider's infrastructure in a variety of ways, such as a cable, phone line, satellite, or fiber-optic connection the other end is connected to any router (or a computer) through an Ethernet cable, and then you can access the Internet (if you connect to a router, the router generally shares WiFi for each device to access the Internet, or connect the device to the Ethernet interface of the router in wired mode.
If it's a DSL (Abbreviation for Digital Subscriber Line, which stands for "Digital Subscriber Line") modem, then connect your phone line to communication. If it is a cable modem, it is connected to the ISP's infrastructure via coaxial cable. This allows your devices to send and receive data over the internet. The router needs to be connected to the Internet through an Ethernet cable, and the modem is responsible for connecting to the Internet.Ī modem is a device that receives an analog signal from your internet service provider (ISP) and translates it into a digital signal that your devices can understand and vice versa. However, if you only have one router, you can't connect to the Internet yet. Servers on the Internet communicate with routers, which direct network signals to corresponding devices on the LAN/private network. While the router is connected to the Internet through a modem, the router itself is assigned a globally unique public IP address (generally referred to as the public IP) on the Internet. Often routers also have multiple ethernet ports, which can be used to connect multiple devices with network cables. Most routers today are WiFi routers, which create a WiFi network to which multiple devices can connect. For example, the telephone line should be equipped with a modem, and the wireless should be through a wireless receiver and transmitter.Ī router is basically used to share a network connection to multiple devices (of course this is a simple description). The remote router is used to connect the remote transmission medium and the corresponding equipment is required. Local routers are used to connect network transmission media, such as optical fibers, coaxial cables, and twisted pairs. Routers are classified into local routers and remote routers.
