...Standard and ThinNet Ethernet • Thick and ThinNet Ethernet: 10-Mbps • As a result of research done at Xerox Corporation in the early 1970s, Ethernet has evolved into the most widely implemented physical and Data link layer protocoltoday. Most co...
...Cable for Gigabit Ethernet longer than 550 meters • You can run Gigabit Ethernet over up to 2-km-long multimode fibre optic cable. However, the transceiver modules used for long-wave (1310-nm) Gigabit Ethernet (1000BASE-LX) launch only single-...
PoE Power over Ethernet • What is PoE? • The seemingly universal network connection, twisted-pair Ethernet cable, has another role to play, providing electrical power to low-wattage electrical devices. Power over Ethernet (PoE) was ratified by...
PoE phantom power • PoE phantom power • PoE over Gigabit Ethernet • 10BASE-T and 100BASE-TX Ethernet use only two pairs of wire in 4-pair CAT5/CAT5e/CAT6 cable, leaving the other two pairs free to transmit power for Power over Ethernet (PoE) a...
...from the computer bus intoserial bits • for transmission. By providing surplus memory in a buffer, UARTs help applications by giving maximum throughput to high-performance peripherals without slowing down CPUs. • Early UARTs didn’t include bufferin...
...handles 100-Mbps Fast Ethernet transmissions very well. • But if you’re running up against the performance limits of a 100-Mbps network, you’ll probably want to upgrade at least parts of your system fairly soon to Category 5e (CAT5e) or higher. • ...
