First of all, I want to introduce myself. I am an electronics technician (Metrologist) by profession. I calibrate and repair test and measuring instruments. In other words I understand any electronics and computer terminologies. My knowledge about computer is not so much. I am more in test and measuring electronics troubleshooting but not so much about computer troubleshooting. I can do computer troubleshooting but in basic one only not on the deepest side. I can share my knowledge and also I want to learn from other techspot member about what they can share.
