hand is used in case of dynamic allocations( mallocs ) like, int *a = (int*)malloc(length*sizeof(int)); Size of the Heap Memory is only limited by the size of the RAM and the swap memory. Memory allocation happens at runtime. it is needed when size of static memory is not ...
Spark has native support to use off-heap memory. The off-heap memory is managed by Spark and not controlled by the executor JVM. Hence GC cycles on the executor do not clean up off-heap. Databricks Photon leverages the concept of off-heap widely Below are the instances...
In Java, memory is divided into two main regions: Heap space and Stack memory. Each region serves a specific purpose and has different characteristics, making them crucial for managing memory during program execution. Heap Space: Purpose: Heap space is used for dynamic memory allocation and storag...
*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 overflow: It occurs when the memory allocated dynamically by the program exceeds the heap size. A heap is a first in first out (FIFO) data structure used to store data that is required for a long time during program running. When the heap overflows, even if the program does not st...

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...

What is unclear to me: What is the use of malloc. As per the reference, malloc is used to allocate memory in heap. At the initial stage of the program in execution, what is the size of the heap memory? At that time does the heap have memory or not. From the output, If the heap...
What is Stack and heap? JVM hasdivided memory space between two parts one is Stack and another one is Heap space. Stack space is mainly used for storing order of method execution and local variables. Stack always stored blocks in LIFO order whereas heap memory used dynamic allocation for allo...
