|Although watching TV shows from the 1970s suggests otherwise, the era wasn’t completely devoid of all things resembling modern communication systems. Sure, the 50 Kbps modems that the ARPANET ran on were the size of refrigerators, and the widely used Bell 103 modems only transferred 300 bits per second. But long distance digital communication was common enough, relative to the number of computers deployed. Terminals could also be hooked up to mainframe and minicomputers over relatively short distances with simple serial lines or with more complex multidrop systems.|
Great article on the history of Ethernet. Hm i wonder if you can still get thicknet
I like this Poem:
The spanning tree algorithm was created by Radia Perlman at DEC in 1985, who also immortalized the algorithm in the form of a poem:
I think that I shall never see
a graph more lovely than a tree.
A tree whose crucial property
is loop-free connectivity.
A tree that must be sure to span
so packet can reach every LAN.
First, the root must be selected.
By ID, it is elected.
Least-cost paths from root are traced.
In the tree, these paths are placed.
A mesh is made by folks like me,
then bridges find a spanning tree.
