Passed my 5th SCNA (Sun Certified Network Administrator for Solaris 8) exam yesterday so my cv has been updated. In with the new and out with the old: I took off the old Solaris 2.4/2.5 certificates and put XHTML on instead. The plan is to go XHTML 1.1 Strict for the whole site and then maybe try to create an even more (? sic!) minimal design utilising a simpler stylesheet.
I came across this a trying to find out what a "jabber" was (preparing for a network exam). The answer to this and the question in the title is found in the comp.dcom.lans.ethernet FAQ:
In the following table, c refers to the speed of light in a vacuum, or 300,000 kilometers per second. Medium Propagation Speed ------ ----------------- Thick Coax .77c (231,000 km/sec) Thin Coax .65c (195,000 km/sec) Twisted Pair .59c (177,000 km/sec) Fiber .66c (198,000 km/sec) AUI Cable .65c (195,000 km/sec) From these values, the size of a bit on 10BaseT can be calculated. 10BaseT is twisted pair, which has a propagation delay of 177,000 km/sec. 177,000 km/sec divided by 10 million bits per second is 17.7 meters, or the size of a single bit on a 10BaseT network.
