Broadband Internet service truly is the most used form of Internet access because of its high access speeds; it is offered in four different forms, DSL (or Digital Subscriber Line), also fiber-optic, cable, and satellite. The old dial-up connection is the only non-broadband internet service available, and even though it is cheaper, most Internet users are moving towards the faster broadband Internet connection.

Leased lines services (or private line services) became digital in the 1970s with the conversion of the Bell backbone network from analog to digital circuits. This allowed AT&T to offer Dataphone Digital Services (later re-branded digital data services) that started the deployment of ISDN and T1 lines to customer premises to connect.

Leased lines were used to connect mainframe computers with terminals and remote sites, via IBM Systems Network Architecture (created in 1974) or DECnet (created in 1975).

With the extension of digital services in the 1980s, leased lines were used to connect customer premises to frame relay or ATM networks. Access data rates increased from the original T1 option up to T3 circuits.

WiFi hotspots are internet access points that allow you to connect to a WiFi network using your computer, smartphone or another device while away from your home or office network.

Many cities, businesses, and other organizations have begun offering WiFi hotspots, which help people stay connected to powerful, fast internet connections, which are often much faster than wireless cellular networks.

A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. They’re designed for long-distance, high-performance data networking, and telecommunications. Compared to wired cables, fiber optic cables provide higher bandwidth and transmit data over longer distances. Fiber optic cables support much of the world’s internet, cable television, and telephone systems.

An intranet is a private computer network that uses Internet Protocol technologies to securely share any part of an organization’s information or operational systems within that organization. The term is used in contrast tointernet,a network between organizations, and instead refers to a network within an organization.
