ADSL stands for "Asymmetric Digital Subscriber Line". ADSL is a broadband connection technology which utilises existing copper wired telephone networks. ADSL uses a wide range of frequencies over an existing telephone line to deliver much higher speeds than your standard 56k modem (between 10 and 40 times faster). An ADSL Modem can be easily installed into a standard PC for accessing the internet. A good quality modem is becoming an essential part of a fast and reliable connection to the Internet.
Routers allow one or more computers to share a single ADSL connection. They also work with any operating system as they are network based. A typical ADSL router with have features such as being able connect either 1 PC or a Hub to the router, speeds of up to 8mbps download, 1024mbps upload, built in basic firewall with NAT and DHCP support. Routers themselves can be defined as a process preformed which moves packets of data around the Internet. Routers such as ADSL make sure that a message is sent and recieved and is part of what makes TCP/IP such a useful protocol suite. To be able to successfully start routing a router uses headers and a forwarding table to find the destinations for packets. Routers use the ICMP protocol section of the TCP/IP protocol suite.
