The header structure (IMAGE_SECTION_HEADER,contains information for the loader so that it knows how to locate the section in the PE file, which memory address to load these sections to and how large memory need to allocate for them. 

PointeToRawData contains the offset of the corresponding section data in the file. 

SizeOfRawData gives the size or end point of the section. 

VirtualAddress gives the relative offset the section to be placed in memory. 

VirtualSizr indicates the memory block to allocate for the section. 

Characteristics indicates the protection attribute for the section in memory (read, write, execute). These attributes are not mutually exclusive and can added together.
