What's the difference between ADSL, ISDN, fiber+LAN and dial-up Internet access?

LAN access: Using optical fiber Ethernet technology, optical fiber to the building and twisted pair to the home are the best access technologies in the current network technology, with the characteristics of high bandwidth, high stability and mature technology. Local area network access provides each household with exclusive access bandwidth of 10240K, which is more than 180 times of the bandwidth of dial-up Internet access (56K), and can be quickly upgraded to 100Mbps as required. Local area network access does not occupy the user's telephone line, but is the user's private line. Just as cable TV can only watch TV when it is connected to a cable TV socket, LAN access users can only surf the Internet when their computers (or other access terminal devices such as set-top boxes) are connected to LAN access information sockets.

HFC access: HFC technology mainly uses CATV coaxial cable, which can carry bidirectional modulation signals after bidirectional conversion. Users can surf the Internet through cable TV cables by adding cable modems. HFC network can provide the original cable TV service, voice, data and other interactive services.

XDSL access: DSL technology is a broadband Internet access technology based on twisted copper wires (ordinary telephone lines), including HDSL, ADSL and VDSL. ADSL is more popular. After the transformation of ordinary telephone lines, users need to add an ADSL modem, so they can surf the Internet through telephone lines.

ISDN access: ISDN technology is a narrow-band Internet access technology using traditional telephone lines. Users need to add special client devices to access the Internet through telephone lines. ISDN technology combines communication and data processing, so users can surf the Internet and make phone calls at the same time. It has been eliminated.
