| Generally, memory is automatically managed by program.                     | Generally, memory management to be done by programmer.                             |
| Traditionally used to stores temporary variables created by each function. | Variables created on the heap are accessible by any function, anywhere in program. |
| Limit on stack memory size.                                                | No specific limit on heap memory size.                                             |
| Self cleaning memory.                                                      | Memory cleanup required explicitly.                                                |
