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 ...
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...
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...
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 ...
Memory leaks:A memory leak is a continuous increase in shared resources—memory—by the computing process because it doesn’t free up previously allocated memory that it doesn’t need. This happens because of a malfunctioning memory, wrongly configured applications, or source code error. As memory...

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...
The stack is a place in the computer memory where all the variables that are declared and initialized before runtime are stored. The heap is the section of computer memory where all the variables created or initialized at runtime are stored. What are the memory segments? The distinction betwee...
One common technique is to divide the heap's memory space into three generations based on an object's longevity: All newly created objects start in the first generation. Short-lived objects, such as temporary variables, never make it out of this generation. The garbage collector identifies them...
