What is the maximum amount of memory any single process on Windows can address?

Question

What is the maximum amount of memory a process can hanve on Windows ? Is this different than the maximum virtual memory for the system? How would this affect a system design?

Answer 1

It depends on 32bits or 64bits.
For 32bits 2^32 = 4.2 billion ~ 4G of max memory

Often this memory is divided into 2 part : 2G for kernel and 2 G for applications.
