A section object represents a section of memory that can be shared. A process can use a section object to share portions of its memory address space (memory sections) with other processes. Section objects also provide the mechanism by which a process can map a file into its memory address space.
Each memory section has one or more corresponding views. A view of a section is a portion of the section that is actually visible to a process. The act of creating a view for a section is known as mapping a view of the section. Each process that is manipulating the contents of a section has its own view; a process can also have multiple views (to the same or different sections).
