some of the IEEE 802 standards

• 802.1 higher layers
• 802.2 logical link control
• 802.3 Ethernet - LAN architecture developed by Xerox Corporation in cooperation with DEC and Intel in 1976, uses a bus or star topology
  • 802.3 10Base5 (original Ethernet) - thick coax, rates of 10 Mbps
  • 802.3u 100Base-T (Fast Ethernet) - twisted-pair, rates of 100 Mbps
  • 802.3z Gigabit Ethernet - rates of 1 Gbps

• 802.4 token bus
• 802.5 IBM token ring

• 802.11 wireless LANs - called "Wi-Fi" (wireless fidelity)
  • 802.11a - 54 Mbps, 5 GHz radio band
  • 802.11b - 11 Mbps, 2.4 GHz radio band
  • 802.11g - 54 Mbps, 2.4 GHz radio band

• 802.15 personal area network - called "Bluetooth"

• 802.16 broadband wireless - called "WiMax" for Worldwide Interoperability for Microwave Access

some of the modem standards for analog telephone subscriber lines

• V.24 - current version of RS-232 interface
• V.21-V.29 - 300-9600 bps

• V.32 - 9600 bps (at 2400 baud, with error correction)
• V.32 bis - 14400 bps (at 2400 baud, with error correction, fax modems)
