Transmission standards
10Base5
The transmission medium for 10Base5 consists of a thick coaxial cable ("yellow cable") with a max.
transmission speed of 10 Mbaud arranged in a line topology with branches (drops) each of which is
connected to one network device. Because all the devices are in this case connected to a common
transmission medium, it is inevitable that collisions occur often in 10Base5.
10Base2
10Base2 (Cheaper net) is a further development of 10Base5, and has the advantage that the coaxial cable is
cheaper and, being more flexible, is easier to lay. It is possible for several devices to be connected to one
10Base2 cable. It is frequent for branches from a 10Base5 backbone to be implemented in 10Base2.
