Difference between a switch, a router and a modem

Difference between a switch, a router and a modem There is lot of difference between a switch, a router and a modem. You may have wondered why when you have bought a router you still had to use your old router or modem in order to get on the internet. And if your old router was needed it was because it was having a built in modem as well.

Usage Of Modem: When you have ADSL broadband, when you access the internet data is sent down your phone line and when the data is received or send down your phone line, it needs to be translated back and forth from analogue signals to digital information. A modem is able to do this.

The short form of modem is modulator or demodulator. As ADSL modem with an Ethernet interface can be used to connect one device to the network, however it has limitations compared to the router. Usually if you buy an ADSL modem with Ethernet it is usually to connect to the router Usage Of Router: You will see on most routers multiple Ethernet ports on the back of the device. This will allow you to connect multiple devices to the router in order to share the internet connection. A router without a built in modem will also need to be connected to an ADSL modem in order to translate analogue signal to digital information.

For example ADSL modem with the Ethernet interface will connect to the router via an Ethernet cable. A switch is usually used in complex network setup scenarios for example in an office environment or in an environment where there are lot of devices connected to the local area network. A router understands which device to send data to as it received. A router essentially is a switch built in although not as sophisticated as a switch.

Usage of switch: Switch will allow multiple devices to be connected to a network. Do note that switch simply connects multiple devices to a network and still requires a router to be able to send that data out to the World Wide Web (however, correctly, a router sends data between computer network – and the internet is essentially a huge interconnected network.

Switches are relatively in expensive now and are definitely to be used in a corporate environment. However is there is any requirement in a home or home office environment you can purchase switches with 8 Ethernet ports. Today I have found 24 port switch for £149.99.

What needs to be Done at home: At home you usually have a micro filter( to prevent the interface between the analogue devices and the DSL connection) and in an ADSL broadband setting, an ADSL broadband cable (which is grey in color, and also referred to as RJ11 ADSL cable) is connected to the router (or modem, if your router doesn’t have built in modem). If your router doesn’t come with built-in Wi-Fi, you could connect your computer (or other electronic device or a switch) to one of the available Ethernet ports.

If you are going to buy new equipment then it is best to buy a wireless router with a built in modem. You then simply need to connect to the ADSL cable and either the Ethernet Cable into your computer or connect to the Wi-Fi network. Don’t forget to secure the Wi-Fi network if it is not while buying a wireless router. The documentation or manual that comes with your router explains you how to do this.
