It merely allows ATM or PPP or PPPoE traffic to be transmitted across telephone lines, cable wires, optical fibers, wireless radio frequencies, or other physical layers. DSL modem, cable modem) by itself provides none of the functions of a router. You agree that we have no liability for any damages.A modem (e.g. User assumes all risk of use, damage, or injury.

Modem: Comparison Chartĭye, Mark A., at al. A DSL modem allows broadband access from your home network to the ISP over a telephone line. A cable modem allows broadband connection from your home network to the ISP over a cable connection. Examples of modem include a cable modem or a DSL modem. A firewall also acts as a gateway that examines incoming and outgoing packets based on a set of defined rules in order to restrict suspicious packets. It allows computers within the local network to send and receive data over the Internet. – A router is the best example of a gateway device commonly used in home networks which routes IP packets between networks. It provides access for IP packets into and/or out of the local network. A gateway, as the name suggests, acts as a gate between two networks, connecting multiple networks with different protocols together. It transmits and receives data over a communication channel, such as telephone line, coaxial cable and optical fiber. A modem is used with telephone line or cable to convert the data signals to those more compatible with the phone line capabilities. Phone lines are used for analog, voice signals. – A modem is used to make a high-speed broadband Internet connection from your home network to the ISP using the telephone line. Generally speaking, a gateway is a network point that acts as an entry point to another network. Gateway, on the other hand, is a device that combines the functionality of both a modem and a router on the same box. ![]() It is simply a hardware component that allows any networking device to connect to the Internet. ![]() – A modem, short for modulator-demodulator, is a hardware device that connects to your cable or telephone line and converts or modulates an analog signal from a cable or telephone line to digital data that a computer can easily recognize and understand. ![]() It can be a router, a firewall, server, or any other networking device that enables traffic flow in and out of the network.ĭifference between Gateway and Modem Device It basically acts as a gate between two networks. The default gateway specifies where the data traffic is to be sent when the destination address is not in the same LAN or is unknown. In a broader sense, a gateway serves as a link between computers using different protocols, platforms or operating systems. A gateway is a router interface connected to the local network in the sense it is a way out of a subnet or a connection point to a different subnet or network. A gateway is a network point that acts as an entry point to another network. ![]() Well, the term gateway has several meanings in the networking world. Gateway is a hardware device that functions both as a modem and a router by combining the functionality of both on the same box. ![]()
