+ * - A data segment
+ *
+ * The code segment is the portion of the object file that contains
+ * executable instructions.

+ * The read-only data segment in the portion of the object file that
+ * contains (as one would expect) read-only data, such as fixed constant

+ *
+ * The data segment is similar to the read-only data segment -- it contains
+ * variables and data structures that have predefined values, however,
+ * entities within this segment can be modified.
