The following technologies are provided by access providers, when they access the internet to the users through these:  computer modems with acoustic couplers, telephone lines, television cable (CATV), wi-fi, and fiber optics.  Access providers can also provider other services for small businesses, like dial-up, DSL,asymmetric digital subscriber line,cable modem or Integrated Services Digital Network.  Access providers may cater these different technological services to medium-to-large business - higher-speed DSL, Ethernet, metropolitan Ethernet, gigabit Ethernet, Frame Relay, ISDN Primary Rate Interface, ATM (Asynchronous Transfer Mode) and SONET (synchronous optical networking).


An organization which provides fiber optic internet services for hosting electronic mail domains with access to storage for mail boxes is called a mailbox provider.  A mailbox provider can also be an access provider, if it also offers similar services of access providers.  Email servicing is the main function of mail providers, such that sending, receiving, accepting and storing emails for end users are processed by mail providers.
