Electro Static Discharge or ESD                                      Short for ElectroStatic Discharge, ESD is one of the few things you can do to damage or destroy your computer or parts in your computer. Like the shock you receive when rubbing your feet on the carpet and touching something metal, ESD can occur when working in your computer and can cause damage to components. ESD can occur without the user feeling a shock and only occurs while working on the inside of the computer or handling an expansion card or other hardware.

That could mean just two total possible values, 255, 4,294,967,296, or anything as long as it’s not ∞ (infinity).  Working with electronics means dealing with both analog and digital signals, inputs and outputs. Our electronics projects have to interact with the real, analog world in some way, but most of our microprocessors, computers, and logic units are purely digital components. These two types of signals are like different electronic languages; some electronics components are bi-lingual, others can only understand and
