Many judges aren't that technically minded. They rely on others to explain how all this stuff works.
A wrong interpretaion could lead to a wrong decision.
I have first hand knowledge of this as the company that I worked for was taken to court (UK Small claims Court) over an alleged faulty CD Writer.
I was a witness on behalf of our company and the other side was using an independant technician.
Before any decision was made the independant techie and I were trying our best to explain to the Judge how a CD writer worked. No easy task when the judge hadn't even used a computer before.
