The company that offers customer access to the Internet is called an Internet Service Provider (ISP). There are four basic types of Internet service; the dial-up, DSL, cable and satellite:
o A dial-up connection uses a telephone line. Although it is cheaper compared to other forms of Internet connections, it is also much slower in terms of connection speed.
o A DSL or Digital Subscriber Line typically provides instantaneous Internet connection.
o Cable connections, like DSL, make use of a modem that is installed from a television cable connection, giving its customers medium to high Internet connection speed. Often, ISPs deliver speedy service and quick response period since customers get to communicate with them online, with the use of their excellent Internet connection technologies. Otherwise, the customers may turn to other ISPs to enjoy much better service. For small businesses, an ISP usually provides other services that may be offered in service packages that include high-speed Internet connection.
Most ISPs provide service contracts in a form of Service Level Agreements.
