Every major business uses Internet for its various applications. In US, broadband users constitute approximately 53 % of the residential users' population. There are both local and national service providers.
Speeds on the Internet are expressed in Mbps (mega bytes per second) or Kbps (kilo bytes per second). Upload and download are the two different speeds provided by high-speed providers like broadband. The upload speed refers to accessing e-mails, file attachments and other data that needs to be sent. The download speed refers to surfing, accessing information and related usage.
A dial up costs up to $20 per month, whereas the cost for an unlimited broadband can go up to $45. High speed ISPs (Internet Service Provider) offer greater reliability along with high speed. This feature could offset the high cost against the facility provided.

A broadband speed can be as much as 150 times the speed of a dial-up connection. High-speed ISPs include Cable, DSL (Digital Subscriber Line) and Satellite service. Cable service operates through cable wires. Its services are dependent on the company that provides cable TV service.
DSL, on the other hand, uses the telephone wires without affecting the voice service. The speed of the DSL connection is inversely proportional to the distance from the issuing company's central office.
Satellite service requires installation of a satellite dish. There is a limit to the amount of bandwidth that can be used in a specific time-period. This reduces its cost effectiveness. The monthly subscription could vary from $50-$100. This service is appropriate and best suited for remote areas with no access to DSL or cable.

Wi-Max service is an upgraded version of the popular Wi-fi. It covers a much larger distance of 30 miles @ 70 mbps, compared to the earlier 300 ft @ 6 mbps. It is however available only in 40 metropolitan areas, and has a long way to go before it is widely available.
