Only 30 network attachments are allowed per cable plant. The amount of shielding in this cable has been reduced, although it is more than enough for most applications. Repeaters are used to extend the cable length, thereby allowing more than 30 network attachments to communicate. Changing the cable plant does not change the repeater rule. No more than four repeaters may separate two communicating devices on an Ethernet network. Unshielded Twisted Pair Until the Unshield twisted pair (UTP) cabling scheme was devised, thin coaxial cable was the most commonly used cable type in Ethernet network environments.
4. Transport layer. This layer provides for end-to-end (origination station to destination station) transmission of data. , with a guarantee that it will be delivered in the same order that it was sent). It ensures that data are transmitted or received without error, in the correct order (received in the same order as the data were sent), and in a timely manner. Included in this layer is the provision for end-to-end communication, but over an unreliable protocol. This is used for mail programs, network management, host name resolving, and other protocols that do not need the robustness of a reliable transport.
A physical topology includes the cable plants, for example. A logical topology covers the access method, such as Ethernet, Token Ring, or FDDI. Ethernet has evolved from a bus topology both physically and logically, to a physical star topology and a logical bus topology. This means that for 10BaseT networks, the wiring changed from having all stations connected to a single cable segment to having each station basically having its physical cable connected to a wiring concentrator. Logically, however, all stations still see all packets transmitted on the individual cable plants.
