Hi i had many experience in Hardware, Network, Linux, Maintenance of Laptops and Desktops along with degrees and diplomas ,but aside from all these all these paperworks the most important thing in live environment is your way of managing your work loads and handling issues through dedication, concentration and analysis of issue instead of getting things messed up. Here in this technical field you wont get the issues what you have learned and what all you have solved earlier ,So its better to develop yourself to work in any versatile environment according to demand and requirement of your boss. Have fun.......
