a stack is a last in, first out (LIFO) structure. A real-life example is a stack of plates: you can only take a plate from the top of the stack, and you can only add a plate to the top of the stack.
If the current size of the heap is too small to accommodate new memory, then more memory can be added to the heap by the operating system. This is one of the big differences between the heap and the stack. How are the stack and heap implemented? The implementation really depends on the...
what is stack? stack is a special area of computer’s memory which stores temporary variables created by function. in stack, variables are declared, stored and initialized during runtime? what is heap? the heap is a memory used by programming lauguages to store global variables, by default, ...
The stack is faster because the access pattern makes it trivial to allocate and deallocate memory from it (a pointer/integer is simply incremented or decremented), while the heap has much more complex bookkeeping involved in an allocation or free. Also, each byte in the stack tends to be re...
*Computers rely on two different memory allocation models, known as the stack and the heap; both live in the computer’s RAM. The stack is neatly organized and holds data in a Last-In, First-Out model. Whatever piece of data was most recently placed in the stack will be the first to...

Heap-based buffer overflows: A heap-based attack is more difficult to carry out than the stack-based approach. It involves the attack flooding a program’s memory space beyond the memory it uses for current runtime operations. Format string attack: A format string exploit takes place when an...
