Data segment is a storage for named variables, declared like "int x = 0;" or "static int x = 0;" outside functions, or as "static int x = 0;" inside functions. Data segment also stores initial value of arrays, like "Hello, World!" for strings, or {1, 2, 3} for integer arrays. This data segment is allocated once, when process starts, and the number of variables here cannot grow.

(One more thing which is stored in data segment is "virtual tables" of classes having virtual functions).

Heap area is for unnamed variables, allocated only when you explicitly call new or related. So the number of variables varies here during program execution.

While variables declared in global data segment can be accessed by name, the variables allocated in heap have to be accessed by pointers or references.

So the main difference between global data segment and heap is that the size of data segment is fixed, while the data allocated in the heap can vary.

That is my understanding.
