Alternatively called an access provider or network provider, an ISP (Internet service provider) is a company that provides Internet access to users or subscribers of its service. An ISP gives you an Internet account (access to the Internet), e-mail address, web space for a web page for around $20.00 U.S. dollars a month. Prices may vary in other countries.
An ISP is also sometimes called an IAP (Internet access provider) and online service provider.
As more people move to broadband, the traditional dial-up ISP and all its services is being replaced. Today, if you are using broadband, you have a broadband provider such as Comcast and are probably using other online services to provide other services. For example, using Gmail as your e-mail provider.
Other services known as an OSP (online service provider) like AOL allow access to proprietary features such as chat rooms, stocks, software, more support, and accessibility globally. These services used specialized software or browser to give their users access to these services. Today, all OSPs are now only an ISP as all services are provided through the Internet and any browser.
