Switched and Fast Ethernet

• Ethernet Switch
  • Functionally same as bridge
  • Much faster hardware switching fabric
  • Cut-through switching vs. Store and Forward
  • Railway station with single LONG Platform
  • Railway tracks with intelligent switching
• Fast Ethernet (802.3u, June 1995)
  • 100BaseT4 (can use Category 3, but 4 pairs needed)
  • 100BaseTX (2 pairs of Category 5, Full duplex)
  • 100BaseFX (2 strands of multimode fibre, full duplex, 2 km)
• Gigabit Ethernet (1000BaseFX, 1998)
• Hubs/Switches with 10BaseT and 100BaseT ports, 1000BaseFX combinations of media available.
