Digital subscriber line (DSL) technology enables data to be sent over existing copper telephone lines by sending digital pulses in the high-frequency area of telephone wires. It allows faster data transmission than traditional dial-up service technology. Integrated services digital network (ISDN) technology also uses telephone lines but it requires dedicated digital lines and offers more advanced features than DSL. Cable modem technology uses cable TV lines instead of telephone lines to transmit data. Fiber-to-home technology uses fiber-optic cables to deliver high-speed internet connectivity.
