A section of an object file is the smallest unit of relocation
and must be a contiguous block of memory.
A section is identified by a starting address and a size.
Information describing all the sections in a file is stored
in section headers at the start of the file.
Sections in an
input object file are called
input sections; sections in a file created by
are called output sections.
Sections from input files are combined to form output sections
that contain executable text, data, or a mixture of both.
The link editor performs allocation, that is, the setting aside of
some portion of the virtual address space for a section.
Although there may be holes or gaps between input sections
and between output sections,
storage is allocated contiguously within each output section
and may not overlap a hole in memory.
