A broadband router is a computer device that receives or forwards data packets to and from the Internet towards a destination in the process called routing. A broadband router is the essential component of the computer networking that enables any sent data to arrive at the right destination.
As an illustration, imagine that the Internet is the world and one computer is one household. Other computers connected through the Internet are households around the world. Say one household will send a letter to another household in any part of the world. The letter has an address right? And that address would determine the destination of the letter. But without one reading the address, the letter would not arrive to the right receiver. The letter also would not be able to reach the intended receiver if there is not medium. This medium would be the courier. And the courier of the computer data is the router.
After connecting the two networks with each other by using broadband routers, now the computer users can share the Internet access easily. The data will be directed along with the computer on local network through the Internet. Data can be exchanged even to computers which are kept at a distant. The added advantage of these broadband routers is to find out the virus attacks.
Routers are first to face any possible outside viruses, hacking threats and so they are vital in a network. But most internet user may not know this, practiced using anti-virus softwares only. A router safeguards your network by working as a filter between the outside internet world and your computers. In general, broadband modems don’t usually have sophisticated built-in security features, so having a network without a router can leave the door open to hackers and other online threatens. Using a router with an in-built firewall makes your wired or wireless network safer and secure, without being vulnerable for internet threats.
Actually, ADSL broadband is accomplished by upgrading your existing telephone line for high-speed internet services. Here ADSL modem routers work by just plugging directly into the upgraded telephone line and thus avoids the need of a separate modem. Once connected, the ADSL modem router is automatically able to share the broadband internet with all the computers in your network.
Cable broadband users connect to the internet via cable modem that is plugged into the cable socket. Cable routers work by plugging it into the provided cable modem’s in-built networking port. This is also known as Ethernet port or RJ-45 connection and you need this to share your cable internet with in your network. Once connected to the modem, which in turn is connected to the cable socket, the cable router shares the broadband internet with all the computers in your network.
