Dial-Up Internet Access
Dial-up Internet access is a form of internet access in which the client uses a modem to dial the ISP's node. The node is a server that uses a protol such as the PPP and TCP/IP protocols to establish a modem-to-modem link, which is then routed to the internet.
Dial-up Internet access was the first method of Internet access that became widely available to the public in the early 1990's. Speeds started at 14.4kbps and have now peaked at 56kbs with error correction. The advantage of dial-up Internet access is that it is cheap and widely available. The disadvantage is that it is slow compared to broadband Internet such as cable Internet and DSL Internet.
