Finally at last you are connected and you begin to browse. You point your browser to your favorite webpage and you wait…and wait, and wait. A few minutes later the webpage has finally loaded. Does this sound familiar? If so you have probably experienced dial-up internet access otherwise known today as 56k. This paper is going to research and show you the many different solutions to that problem, Broadband Technologies!

(Broadband Definition, 2007)

Broadband is often called high-speed internet. The rate you are transferring data at is hundreds of times faster than a typical dial up connection. If you are connected at a speed of 256 kbps or more then you have a broadband connection. There are many types of broadband connections. The two most standard technologies are Cable and DSL. Let’s talk about a cable connection first (Cable Modems, 2007).

Cable technology uses hybrid fiber coaxial network which can deliver speeds of three to ten mega bits per second. Nearly one hundred times faster than 56k dial up (Basics of Broadband, 2007). Cable modems operate on the Physical and Data Link layer of the OSI model. The OSI model is a theoretical representation of what happens between two nodes communicating on a network (Guide to Networks, 44). A cable modem bridges Ethernet frames between a customer’s local area network and the hybrid fiber coaxial network. It also has its own IP address.

This technology is used in many countries including Canada, Australia, Europe and the United States. In 2005 the United States alone had twenty-two million cable users. There are many benefits of using a cable modem connection.
