Employees and students often connect to the Internet through a business or school network. The networks usually use a high-speed line. Some home and small businesses connect to the Internet with dial-up access, which uses a modem in the computer and a standard telephone line. Many home and small business users opt for higher-speed broadband connections, such as DSL, cable television networks, fiber-optic cables, radio signals, or satellite. DSL provides Internet connections using regular copper telephone lines. A cable modem allows access to high-speed Internet services through the cable television network. Fiber to the Premises (FTTP) uses fiberoptic cable to provide nigh-speed Internet access. Fixed wireless connections use a dish-shaped antenna to communicate via radio signals. A wireless modem allows Internet access through a cellular network. A Wi-Fi network uses radio signals. A satellite modem communicates with a satellite dish. An access provider is a business that provides access to the Internet free or for a fee. An ISP (Internet service provider) is a regional or national access provider. An online service provider (OSP) provides Internet access in addition to members-only features. A wireless Internet service provider (WISP) provides wireless Internet access to desktop and notebook computers and mobile devices with built-in wireless capabilities (such as Wi-Fi) or to computers using wireless modems or wireless access devices.
