The internet Access falls into three broad categories: dedicated, dial-up, and wireless. With dedicated access, a subscriber’s computer remains directly connected to the Internet at all times through a permanent, physical connection.
A small businesses or individuals that desire dedicated access choose technologies such as digital subscriber line (DSL) or cable modems, which both use existing wiring to lower cost. A DSL sends data across the same wires that a telephone service uses, and cable modems use the same wiring that a cable television uses. Another less popular is the satalite internet access.
The most least expensive is the Dial-up,but it is also the least convenient. To use dial-up access, a subscriber must have a telephone modem, a device that connects a computer to the telephone system and is capable of converting data into sounds and sounds back into data. The user’s ISP provides software that controls the modem.
