I was reading a networking book and they explain everything but how they came up with the amount of host or the minimul distance between host. Is these random numbers they came up with or is there a reason behind it?
Why does 10Base2 only allow a max of 30 host per segment and min of .5 meters be

What are you talking about %26quot;random numbers%26quot;?
These values are calculated as the amount of host transceivers that increase attenuation on the line in each segment. Also, transmissions on coax only 18 inches long is tantamount to a short! It%26#039;s almost like physically touching your antenna%26#039;s together, you have to let at least one wave length out of the darn transmission line or antenna.
I have been in this biz so long that we actually used 10base2 and thicknet (and star arcnet and token ring!) In any case these values are for the STAR/BUS segment style. The star only style worked much better, but hubs for 10base2 were uncommon, especially active hubs (re-transmitter powered hubs (MAUs)). In any case, to use a cable less then half a meter long meant that those two network devices were unworkably close together anyway.. no worries... and don%26#039;t forget... every workstation has a T connector and the last one on the segment has terminator (resistor) at the empty end of the T.

- These requirements have taken into account the technical limitations of signals degrading along your medium, as well as best practices to avoid congestion on any networking segment.
Work with it.
If you later encounter problems on your network, you can know that it is not because your cable run exceeded the maximum segment length, or because you have too many hosts per segment.
