Section alignment

In MS Windows executable file terms, value that describe alignment of the PE-file's sections in memory when the image has been loaded.
Each section is guaranteed to start at a virtual address that's a multiple of this value.
For paging reasons, the minimum section alignment is 4096 bytes.
It's possible to change section alignment with using /Align linker option which specifies the alignment of each section within the linear address space of the program.
