quit taking me to school! That's it! I'm opening another bottle of wine! lol! I remember in school, bits, bytes (string of bits), 0's/1's, buffers, diodes, capacitors, gates, Ram, dram, spam (oh, that came later), basic programing, and more. The job I got being certified, consisted mainly of troubleshooting, then swapping out parts of the electronic machines we serviced. Mainly copiers, lazer printers, fax machines, others. mguru
