Kinds of Home Internet Connections


We use internet for many purposes such as surfing news, chatting, business, search, contacting with each other, watching videos and many other things. This service is available in houses, cafes, universities and ect. The kinds of internet connections are differ and mediate between their speed and qualities like dial up, cable and DSL. Before few years ago, the dial up was the most used one. Now, there is a war between DSL and cable, because many people now prefer to use DSL or cable cause of their qualities. So, the time of dial up is over now and few people use it.
“You don’t use DSL yet?” or the “You don’t use cable yet?” you will hear those questions of other if you still use dial up. Speed, customer satisfaction and security are the three things that allow us to compare between DSL and cable. Theoretically, cable modems run faster than DSL because they offer more bandwidth. There is also a form of DSL called VDSL which can match the speed of a cable modem. However, the speed of cable is relative to the number of people in your area who are accessing the neighborhood at the same time. One popular commercial compares cable modems to drinking out of a straw – the straw is fine, if one person is drinking from it. But if the straw must be shared – well, obviously things slow down a little. Both DSL and cable also vary in speed by the minute depending on the congestion caused by multiple users.
Customer service surveys conducted by J.D. Power and Associates in 2004 showed that DSL had an edge over cable in customer satisfaction ratings. This survey looked at billing, the provider’s business image, cost and tech support, and email services. EarthLink and Verizon, both DSL, was the top two service providers rated in the survey.

Since cable modems necessitate the sharing of a cable line to provide service to the entire neighborhood, DSL is slightly more secure. However, cable modems are easier to install, and many sources believe that the difference in security is not significant enough to go through the trouble of installing DSL. Many cable customers avoid security problems by putting up firewalls in order to protect themselves, and their information.
So, these are the internet connections that we can choose between them and see what is suitable for us. We must know for what we want to use the internet and why in order to choose the connection according to its speed and security
