10BASE5
10BASE5 transmitted 10Mbps over a single thick coaxial cables thus giving the name of Thicknet
- First medium used for Ethernet
- Part of the original 802.3 standard
- Inexpensive and do not required configuration(no needs for hubs to extend the length of systems)
- Technologoy is very sensitive to signal reflections
- Cable-dependent across the whole collision domain and it represents a large single point of failure.
- 10BASE5 uses Manchester-encoded signals.
- Other specifications or limitations are:
- Only one station can transmit at a time (collision will occur)
- 10Base5 can run only in half-duplex mode (subject to CSMA/CD rules)
- 100 stations & including repeaters can exist on any individual 10Base5 segment.
