Router routes the data packets to the respective computer basis the IP mentioned on their header. ‘0’ or ‘1, and demodulates from digital to analogue. Process Modem receives the analogue signal from the telephone and modulates it to digital form, i.e. A router is not essential to access the internet. Internet Access A modem is required to access the internet as it connects your local area network to the internet service provider. ![]() The device routes the information to the respective computer connected to the local area network. Purpose It is a device that carries information from the internet to your local area network. A router is a hardware that connects or routes data within one or multiple local area networks. This type of hybrid device (sometimes called a gateway) is offered by some ISPs to simplify the setup process.Comparison Table Parameter of Comparison Modem Router Definition A modem is a hardware that modulates the analogue signal from a phone or cable to a computer and demodulates it from a computer to a phone or cable. Important: While the router and modem are often separate entities, it has been more common for the modem and router to be combined into a single device. To summarize, the device connection order is outlined below: The router provides a local IP address to each connected device, but they will all have the same external IP address, which is assigned by your ISP. DSL modems have a telephone connector, also called an RJ-11 jack, which connects to a telephone socket on the wall.īy connecting your modem to your router (instead of directly to a computer), all devices connected to the router are connected to the modem, and therefore, the Internet. This connects to a cable port on the wall. Cable modems have a coaxial (or "coax") connection, which is the same type of connector found on a TV or cable box. The modem connects to your ISP, which typically provides either cable or DSL Internet service. Therefore, most routers have a specific Ethernet port that is designed to connect to the Ethernet port of a cable or DSL modem.Ī modem is a device that provides access to the Internet (see below). In order for devices on the network to connect to the Internet, the router must be connected to a modem. Wireless routers allow multiple computers and other devices, such as smartphones and tablets, to join the same network.Ĭonnecting to a router provides access to a local network ( LAN), but it does not necessarily provide access to the Internet. "Wireless routers" often have one or two moveable antennas, though some models keep the antennas inside the enclosure. While early routers only had Ethernet ports for wired connections, most modern routers provide wireless connectivity as well. ![]() Fortunately, the functions of the two devices are pretty easy to understand.Ī router is a small box that allows multiple computers to join the same network (see below). While the two devices may look similar, they each serve a different purpose. Answer: Routers and modems are two of the most common computer peripherals, yet many people do not know the function of each one. ![]()
