I would like to know difference between static variables and global variables in terms of access speed and space consumption. (If you want to know my platform: gcc compiler on Windows. (I am using Cygwin with Triton IDE for ARM7 embedded programming on windows. Triton comes with gcc compiler on Java platform which can be run on Windows.))
(Obviously I know in terms of file and function scope from this question)
Edit: OK give me an answer on any micro controller / processor environment.
