Hi guys i come up with this simple tutorial, some may know, while others may not, so while the Internet is catching up on everybody, let me do a simple tutorial between Cable and DSL, so that when choosing a internet service, you people make informed choices.

Introduction

Cable and phone companies have been battling to provide high-speed internet services for years. But recently, cable is currently winning.
In 2005, there are more then 19 milloon cable service subscribers and around 14 million DSL subscribers across the US. Although they are touted as high speed alternatives, they don't work the same way.

Real Speed Difference

A Cable connection offers a maximum potential data transfer rate of 30Mbps, Real world speed however, are generally much slower, at about 1.5 to 3 mbps.

DSL doesn't use cable wiring to supply the internet access, instead DSL flows through the copper telephone lines already installed in the home.
For DSL, optimal data rate as less then 6mbps, but most people find that their top speed is around 1.5mbps.

Factors that affect the speed

For DSL, Distance affects the speed. For example, if you are very near to the telephone company, the faster your connection will be. But DSL speed is more cinsistent than cable becuase you have your own direct line that provides a constant data rate.

Cable have speed limits too, but for different reasons. If you connect to a cable line, you are plugging into a network that includes your neighbour who use a cable connection. As more people flip on their cable modem and surf web, you will encouter slower speed as your are sharing bandwidth. So therefore you see many cable service providers does not advertise data transfer speed as a selling point.


Network and Security

Cable works through LAN but the cable modem integrates hardware based security that can protect the PC from attacks.

DSL provides a slightly more secure setup, but you need to use your own software like firewall to keep the data safe.


Costs and Service

Cable modem service typically costs more than DSL. Research shows that in late 2005, cable service was up to 75 percent more expensive than DSL.

When choosing between DSL and cable, remember to talk to your neighbours about their experiences. If they have nagging problems with a specific service e.g. Always DC , heed their warnings.
