When I joined my first company I had to give a number of presentations on the market scenario in different parts of the country. I had to set up the audio video on the computer and keep everything ready before the bosses could enter the conference room. Initially I did not know How To Connect AV To Computer so I used to call my colleague to come and help me out. But soon I realized that I better learn how to do the connection because if my colleague fails to turn up one day in office then I would have no one to help me. So I began taking interest in how the connection is made from the computer to the projector and speakers. Over a period of time I was so comfortable doing this connection that whenever there was any problem with the connection they started calling me to rectify the problem. I now teach my juniors how to setup an AV connection to a computer so that when they have any presentation they can do the setup themselves.
