An ISP or Internet Service Provider is a company that sells you broadband service. ISP give end users access to the Internet. Different ISPs have different services. It varies from service provider to service provider. Broadband service providers might provide end users modem, microfilters, and the necessary drivers to install software that gives users access to the Internet.
Three categories of broadband service providers emerge.
ASDL – ASDL is also expanded as Asymmetric Digital Subscriber Line. It is a type of Digital Subscriber Line technology that gives you Internet access over phone lines.
Cable – Unlike ASDL, Cable broadband uses twisted co-axial copper cables to deliver data to Internet users. A cable start at a CMTS (Cable modem termination system), and ends at it. The CMTS regulates the upstream and downstream data flowing from and to the modem.
Satellite broadband – Satellite broadband is Internet delivery using satellites. Satellites beam Internet data to antennas of end users or to a nearby tower station. Satellite has not been favorable on account of expensive set up costs and performance problems.
Now, you need to choose the type of broadband service you want. Do you want a satellite internet or a simple DSL connection? Do you want an ASDL connection that makes use of phone lines? You cannot expect great speeds over phone lines. Or do you want to go for cable connections? This is a popular way of Internet access and is widely accepted. The third is satellite based Internet service. You should go for this only if you live in an area where there are no phone lines, and no feasibility for laying a cable Internet service.
