![]() In both the modem as well as routers, the data is transmitted in the form of PACKETS.Ī modem is an INTER-NETWORKING device whereas, a router is a NETWORKING device.Ī Modem does not provide any kind of security whereas Router provides security by protecting the network. Modem resides in DATA LINK LAYER whereas, Router resides in NETWORK LAYER. ![]() It comes up with multiple ports which can be used to connect devices using Ethernet cables, along with that, it also provides wireless points. In other words, It routes a dedicated internet connection to various devices such as laptops, computers, mobile phones and others, so that, they can access the internet. Routers are used while transmitting data so that they can efficiently direct the Internet traffic. RouterĪ Router can be defined as a networking device that is basically used to carry forward the data packets to various computer networks. The main objective of the Modem is to convert digital signals to analog signals while transmitting and converting back analog signals to digital signals while receiving data. Cable and DSL modem are some examples.Ī Modem stands for Modulator and DEModulator. Similarly, a modem modulates the outgoing signals, coming from computer to analog signals. The router is also a box-type device that allows many computer systems (wired or wireless) to access the internet at the same time. The reason to have modem is because a computer can only deal with digital signals whereas signals present on internet are analog.Ī modem demodulates incoming analog signals from internet to digital signal. It establishes and maintains a dedicated internet connection with Internet Service Provider (ISP) that serves access to Internet. The Vn command (Result Code Form) or -M1 command (MNP Class Connect Messages) must be set to indicate MNP reliable mode in the result code. Key Difference: Modem (short for modulator-demodulator) is a device modulates an analog carrier signal to encode and then decode digital information. It is used to connect a computer to internet. It exposes wireless access points and also provides ports in order to connect multiple devices Without router, it can provide a dedicated connection to single device only It cannot be used alone to connect a device to the internet It can alone connects a device to the internet Modulation and demodulation of incoming and outgoing signalsĪccepts data packets and directs it to correct destination by choosing efficient path It can be defined as a device that is basically used to carry forward the data packets to various computer networks It can be defined as a device which modulates and demodulates the outgoing and incoming data Difference between Modem and Router in tabular form ? Basis The main difference between them is, Modem connects your computer with the internet whereas, router directs and examines data packets to destination devices. A modem and router both are networking devices used for providing access to the internet. Routers normally connect LANs and WANs and have a dynamically updating routing table based on which they make decisions on routing the data packets.
