  4. Transceivers are used to connect nodes to the various Ethernet media. Most computers and network interface cards contain a built-in 10BASE-T or 10BASE2 transceiver, allowing them to be connected directly to Ethernet without requiring an external transceiver. Many Ethernet devices provide an AUI (Attachment Unit Interface ) connector to allow the user to connect to any media type via an external transceiver. The AUI connector consists of a 15-pin D-shell type connector, female on the computer side, male on the transceiver side. Thickwire (10BASE5) cables also use transceivers to allow connections Transceivers

  6. The Original Ethernet The first Ethernet (10Base5) used a bus topology and a thick coaxial cable. Transceivers connect the network adapters to the cable via a vampire tap that "bites" into the coax.

  8. Thin Ethernet 10Base2 Ethernet was a later variation of the original 10Base5. It used a thinner coaxial cable attached to each node using BNC (bayonet Neil-Concelman) T-connectors

  10. Twisted Pair Ethernet Most Ethernets use twisted pair wiring. All cables use RJ-45 connectors between the network adapters in the PC and a central hub or switch Ethernet Switch This 10/100 switch from Omnitron has 16 ports and automatically senses the transmission rate of the line and adjusts accordingly
