Cable Versus Dsl

Vacca INSIDE DSL; Cable Modems; ADSL; CDSL; G.Lite; HDSL; IDSL; RADSL; SDSL; VDSL; POTS; DSL and Cable Modem Rollouts; High-Speed Data Entry; Buying DSL Service; Installing DSL; Security Problems, Residential Users, Telecommuters, DSL System Components; DSL Network; DSL Hubs INTRODUCTION Internet access via cable modem has become available in many residen- tial areas over the past few years. Cable has the capacity to transmit data at speeds as fast as Digital Subscriber Line (DSL) when configured prop- erly and under optimal conditions. Due to the fact that cable lines are not available in the vast majority of commercial districts, cable does not com- pete with DSL in the enterprise market at all, in most cases. Cable was designed for residential use, and in some cases may be a cost-effective solution for residential high-bandwidth Internet access. Therefore, the challenge of cable versus DSL is primarily in the residential and telecom- muter markets. With that in mind, and before continuing with the theme of this article (cable vs. DSL), one can take a look at the technology issues first, and then some basic terminology. TECHNOLOGY ISSUES What is DSL? How does it work? What are the types of DSL? These are some of the questions this article will surely answer; as well as some of the pros and cons of the use of cable modems versus DSL. PAYOFF IDEA The article discusses the current state of cable DSL: What Is It? modem access versus DSL. It also examines how In essence, by using the existing tele- prevalent cable modem and DSL services are in major U.S. -

Introduction The widespread use of the Internet and especially the World Wide Web have opened up a need for high bandwidth network services that can be brought directly to subscriber's homes. These services would provide the needed bandwidth to surf the web at lightning fast speeds and allow new technologies such as video conferencing and video on demand. Currently, Digital Subscriber Line (DSL) and Cable modem technologies look to be the most cost effective and practical methods of delivering broadband network services to the masses. <-- Back to Table of Contents 2.

How Cable Modems Work by Curt Franklin for Millions of People, Television Brings News, Entertainment and Educational Programs Into Their Homes
How Cable Modems Work by Curt Franklin For millions of people, television brings news, entertainment and educational programs into their homes. Many people get their TV signal from cable television (CATV) because cable TV provides a clearer picture and more channels. See How Cable TV Works for details. Many people who have cable TV can now get a high-speed connection to the Internet from their cable provider. Cable modems compete with technologies like asymmetrical digital subscriber lines (ADSL). If you have ever wondered what the differences between DSL and cable modems are, or if you have ever wondered how a computer network can share a cable with dozens of television channels, then read on. In this article, we'll look at how a cable modem works and see how 100 cable television channels and any Web site out there can flow over a single coaxial cable into your home. Photo courtesy Motorola, Inc. Motorola SB5100E SURFboard Extra Space Cable Modem You might think that a television channel would take up quite a bit of electrical "space," or bandwidth, on a cable. In reality, each television signal is given a 6-megahertz (MHz, millions of cycles per second) channel on the cable. The coaxial cable used to carry cable television can carry hundreds of megahertz of signals -- all the channels you could want to watch and more. (For more information, see How Television Works.) In a cable TV system, signals from the various channels are each given a 6-MHz slice of the cable's available bandwidth and then sent down the cable to your house. -

In a networked scenario organisations often need several people (may be at different locations) to input and process data simultaneously. In order to achieve this, a computer-networking model in which a number of separate but interconnected computers do the job has replaced the earlier standalone-computing model. By linking individual computers over 4 7 Network Fundamentals a network their productivity has been increased enormously. A most distinguishing characteristic of a general computer network is that data can enter or leave at any point and can be processed at any workstation. -

From Packet Switching to the Cloud
Professor Nigel Linge FROM PACKET SWITCHING TO THE CLOUD Telecommunication engineers have always drawn a picture of a cloud to represent a network. Today, however, the cloud has taken on a new meaning, where IT becomes a utility, accessed and used in exactly the same on-demand way as we connect to the National Grid for electricity. Yet, only 50 years ago, this vision of universal access to an all- encompassing and powerful network would have been seen as nothing more than fanciful science fiction. he first electronic, digital, network - a figure that represented a concept of packet switching in which stored-program computer 230% increase on the previous year. data is assembled into a short se- was built in 1948 and This clear and growing demand for quence of data bits (a packet) which heralded the dawning of data services resulted in the GPO com- includes an address to tell the network a new age. missioning in July 1970 an experi- where the data is to be sent, error de- T mental, manual call-set-up, data net- tection to allow the receiver to confirm DATA COMMUNICATIONS 1 work that used modems operating at that the contents of the packet are cor- These early computers were large, 48,000bit/s (48kbit/s). rect and a source address to facilitate cumbersome and expensive machines However, computer communica- a reply. and inevitably a need arose for a com- tions is different to voice communi- Since each packet is self-contained, munication system that would allow cations not only in its form but also any number of them can be transmit- shared remote access to them.
