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. What is STAC
Thestackis a place in the computer memory where all the variables that are declared and initializedbeforeruntime are stored. Theheapis the section of computer memory where all the variables created or initializedatruntime are stored. What are the memory segments? The distinction betweenstackandheap...
The stack is set to a fixed size, and can not grow past it’s fixed size (although some languages have extensions that do allow this). So, if there isnotenough room on the stack to handle the memory being assigned to it, astack overflowoccurs. This often happens when a lot of neste...
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...
Cache, primary and secondary memory vary in size and speed, making them each useful in different ways. What is random access memory? Solid-statememory is an electronic device that's represented as a two-dimensional matrix of single-bit storage cells or bits. Each set of storage cells is den...
*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...
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,...

Heap overflow attacks are used to damage heap data. Memory allocation in the heap is dynamic and discontinuous, making it difficult for attackers to predict addresses. Although launching heap overflow attacks is more difficult than launching stack overflow attacks, they can still be launched by attac...
