I didn't grow up with computers. My first PC was an AT 286 and it was allready outdated when I bought it. From day 1 it was the technical stuff that interested me the most. Especially the fact that computers could communicate with each other meant a challenge for me. I wanted to make that happen!
It didn't take very long before I had tied 3 old pc's together with coax cables and MS windows 3.10. Not that there was a lot to communicate, there just wasn't enough memory and diskspace, but it did work :-)
After that I extensively explored the upcoming Internet but I didn't do a lot with the technical stuff until I radically switched carriers and got a job with this large IT company
In just 1,5 years I learned and picked up the ins and outs of TCP/IP,SNA,APPN, had a taste of Mainframe and Unix, learned a lot about routers and routing (CCNP) and became familliar with terms as leased lines, frame-relay and ATM. And I kept learning since..
