Example of Free hosting: www.geocities.com www.freeservers.com www.fortunecity.com Otherwise one needs to pay for professional hosting services. ISP’s may offer this service. Hosting Connecting : Connecting PSDN – Normal phone connection – commonly referred to as a Dial-up connection. [needs MODEM] ISDN - (Integrated Services Digital Network) - Digital telephony scheme that allows a user to connect to the Internet over standard phone lines at speeds higher than a 56K modem allows. This usually entails a direct link to a specific site or application. Connecting : ADSL - (Asymmetric Digital Subscriber Line) is a technology for transmitting digital information at high bandwidths on existing phone lines. Unlike regular dialup phone service, ADSL provides a continuously-available connection. ADSL is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. ADSL simultaneously accommodates analog (voice) information on the same line. ADSL is generally offered at downstream data rates from 512 Kbps to about 6 Mbps. Connecting Connecting : Cable Internet - Uses a cable modem designed to operate over cable TV lines. Because the coaxial cable used by cable TV provides much greater bandwidth than telephone lines, a cable modem can be used to achieve extremely fast access to the World Wide Web.
