I beg to differ slightly on the antiquated terminology [per my NCA/NCE
classes, which while were fun and informative, proved to be a big waste of
time because as soon as I "graduated", being an "MSCE" was the hot
ticket...]

In any case, "base" in 10/100-base-x refers to "baseband" transmissions, the
other option being "broad" for "broadband" transmission [reality check: you
don't care, they both work...]  It was the -2 or -5 that indicated coax [and
thin/thick at that] vs. -t for <T>wisted Pair.  Additionally, the -2
indicated an overall limit of 200 meters, and -5 indicated 500 meters [which
ultimately have to do with the electrical properties of the cable, etc.]
