If you want to understand how your #flashdrive works, you have to understand #CMOS . To understand CMOS, you have to understand #MOSFET . To understand MOSFET you have to understand Bipolar Junction Transistor ( #BJT ) To understand the BJT, you have to understand the #transistor . To understand the Transistor, you have to understand the #TRIODE . And to understand THAT... I have an awesome video explaining how a #tubeamp works for #guitar players here: http://vimeo.com/28565075 and I'm working on going back in time just a *little* bit further but I want to see this first.
