The packet doesn’t reach directly at the desired portion it passes through some network layers. It uses some algorithm in the completion of this process. It maintains a directory of routes available for forwarding a packet of data. Thus it also decides which information to send and where to send. Not much data filtering is done in this process. In this process, it tries it’s best to choose the shortest possible path for the purpose so that you may get the information quickly. It receives information via modem and then transfers it to you.
Modem vs router vs gateway software#
In some case, it can be software on a device.Īs told earlier their purpose is to connect 2 or more devices.It is located at a place where 2 or more systems are in connection with each other.It is an electronic device that connects devices.A router can be used to link computers and do the file sharing in such a case. Well a WiFi can work without a modem too. You will need it because it establishes a connection to the internet called WAN (wide area network). If you want to increase this speed more then you might do it by the process of data compression. This whole process is done at a breakneck speed. Thus the signal travels with ease over telephone lines.Īfter that what comes into action is the demodulation of this modulated signal. Its role can be seen from its name, i.e., modulation-demodulation.įurthermore, it is meant for connecting internet users.Īlso, it modulates the signal in the form of a sine wave. What Does the Modem Do and How It Functions? A 50 kbps – 60 kbps is an entirely reasonable rate. It is measured mostly in bps or kbps (kilobyte per second). You won’t be able to use the Internet and phone at a time with it. It builds a connection with an external one and allows you to go online even when you are using the telephone. It uses cable for establishing a connection. It is a device that works in the modulation of a digital signal for transmission, and then it demodulates the transmission signal again at the receiving end to decode the information.Īlso, read What is DSL Internet Connection? Cable Modem: Although the router is not compulsory for establishing a connection, it provides security measures which modem does not.The first one is needed for establishing a connection while the use of the second one is not mandatory, this is because it is used for creating a connection between networks.The modem is a part of ISP (internet service provider) while the router is a device for your home networks.The modem holds the responsibility of modulation and demodulation of signals so that it becomes easy for digital communication while the router is responsible for connecting two networks and managing traffic between them.The two devices although look the same but are entirely different from each other. What is the Difference Between a Modem And a Router?
