In today’s world, computer networking equipment market offers both the wired and wireless devices that there should be no wonder in it as to why some technologies can be confusing at times. What makes it even more puzzling is the fact that many of these devices use similar techniques which perform identical functions, and require the same sort of cables.
Routers and modems also come in the list- right next to access bridges, repeaters, and several other networking devices.
What is the Difference Between a Modem and a Router
As a name suggest, it is a shorthand expression which is designed for the technical process that the device performs that is both modulation and demodulation. In early days, the term modem was used to describe a method that transformed speech into analog signals which transmitted over telephone line cables. Since then, this term has been broadened to explain the wide variety of devices to perform both the modulation and demodulation in its primary sense.
How it works
A modem includes a physical connector with a coaxial cable which is installed in your home. That cable typically exists in the home with a hole and is tunneled around or underneath the house until it reaches a cable distribution box which is mounted on home exteriors. An additional cable underground connects this box to the service provider node which is mounted on a nearby utility pole.
Modems include lights in their front so that you can see what is going on. One light indicates that the unit is getting power, one shows that modem is successfully sending data and one shows that it is receiving data from internet service provider. And then there is a start of troubleshooting scenario: if both the send or receive lights are blinking, then the internet service provider is having issues or something wrong is happening with the outside connection. Another LED is indicating that weird devices are accessing the internet.
Make a note of it, that modems are not just for cable connection. Broadband can be served with the help of a Digital Subscriber Line(DSL). DSL is slower than cable-based broadband and is also useful in rural areas where phone lines already exist, but there is no infrastructure supporting cables which are based on TV and internet services.
Whether the router is designed for cable-based broadband or DSL, the four Ethernet ports are used for wired devices with a port. These include laptops, desktops, gaming consoles, printer and more. If you want most of your broadband connection, using these ports for your hardware is the ultimate option, primarily when the port supports the speed of more than one gigabit per second.
Modulation and demodulation are the two process where signals traveling between different networks are converted into different modes for transmission over cables or other media.
It is the modem’s work to revert and convert the signals traveling from one LAN over the Internet infrastructure to another LAN.
Routers are computer networking devices which serves two essential functions: first is to create and maintain a LAN and secondly to manage the entering and leaving of data over the network. In more simpler words, a router is a post office of the networking world. As it received data packets from all around the internet, it is organized to end devices within that LAN.
Once set up and ready to go, a router creates a LAN. A LAN is a network that interconnects multiple end devices within a small area such as an office or home. Devices which are connected to LAN can interact with or share data with each other and can also gain access to the internet if the connection is available.
How Routers Works
As routers are network devices which transfer the data packets along networks by determining the paths of systems. It identifies the road to different networks such as transportation, telephone, and electronic networks. It works in two ways either with the help of a control plane or forwarding plane. In control plane, the router acts as a more neat and smart way. It sends the data packets to their desired specific location. While on the other hand, forwarding plane, a router does not need to remember the sending or receiving information of data packets. The primary and primary objective of the router is to deliver the data packets. The forwarding decision takes place at the data link layer of the OSI model. To make a better connection, you must have best routers.…
