10Base5
The transmission medium for 10Base5 consists of a thick coaxial cable ("yellow cable") with a max.
transmission speed of 10 Mbit/s 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.
10BaseT
Describes a twisted pair cable for 10 Mbit/s. The network here is constructed as a star. It is no longer the
case that every device is attached to the same medium. This means that a broken cable no longer results in
failure of the entire network. The use of switches as star couplers enables collisions to be reduced. Using
full-duplex connections they can even be entirely avoided.
100BaseT
Twisted pair cable for 100 Mbit/s. It is necessary to use a higher cable quality and to employ appropriate
hubs or switches in order to achieve the higher data rate.
10BaseF
The 10BaseF standard describes several optical fiber versions.
