A broadband router is a basic device to set up a wired or wireless network. Broadband routers ensure that all the computers on a network can send and receive data to each other and across the Internet. These routers are of both wired and wireless but their features are very similar.
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.
A router (broadband router) is also a device that enables two or more computer to receive data packets from the Internet under one IP address at the same time. Remember that to be able to connect to the Internet, a computer must have an IP address unique from the rest of the computers. Therefore, every computer connected to the Internet has it own IP address. It is like having a fingerprint or ID as an access pass to be able to enter the web. With the presence of the router, this “fingerprint” or “ID” could be shared by two or more computer at the same time.
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.
