Shared Flashcard Set
Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network PSTN to establish a connection to an Internet service provider ISP by dialing a telephone number on a conventional telephone line. The user's computer or router uses an attached modem to encode and decode information into and from audio frequency signals, respectively. Dial-up connections to the Internet require no infrastructure other than the telephone network and the modems and servers needed to make and answer the calls. Because telephone access is widely available, dial-up is often the only choice available for rural or remote areas, where broadband installations are not prevalent due to low population density and high infrastructure cost. Dial-up requires time to establish a telephone connection up to several seconds, depending on the location and perform configuration for protocol synchronization before data transfers can take place.
