History of network topologies

Answer 1

The history of network topologies dates back to 1969-1970. This what when Roberts, who is now known as Dr. Howard, started researching on network topologies and founded Network Analysis Corporation.

Answer 2

Actually, even before the bus topology, the mesh topology was used. This provided a direct link from one computer to another and this was copied for all the computers so that they had links to all others in the network. Of course this became quite cumbersome very quickly, so other topologies were developed such as bus (as used in 10Base2 and 10Base5), star (as used in 10BaseT, 100BaseT, and Gigabit Ethernet as well as the old Arcnet), and ring (most notably used in Token Ring). The ring topology has pretty much fallen into disuse as of today but the bus topology is still used. The most common place to find it is in the delivery of cable TV and cable modem service. It comes through the neighborhood on a trunk line and then each home or office has a tap into that big trunk. It is also used in the delivery of other services to homes and businesses: specifically natural gas, water, and sewer. The star topology is utilized by the phone company to deliver standard phone service as well as DSL services. This is a direct link between the service location and the DSLAM. In this case, the DSLAM is assuming the role of the concentrator or network switch.

Answer 3

The first network topology was the Bus topology. All computers lined up in a row with a Ethernet cable attached to each computer.
