What are Memory Allocation and Deallocation
Memory Allocation
Memory allocation is the process of reserving a portion of a computer’s memory for the use of a program. It involves setting aside a block of memory to store data, variables, objects, or other information that the program requires. The allocated memory can be used to create data structures, arrays, variables, and other dynamic entities. Memory allocation is typically achieved using functions or system calls provided by the programming language or the operating system, for eg. “malloc”, “new”, etc.
Memory Deallocation
Memory deallocation, also known as memory release or freeing memory, is the process of releasing previously allocated memory that is no longer needed. It is essential to prevent memory leaks and ensure efficient use of system resources. When memory is deallocated, it becomes available for reuse by the program or the operating system. Common memory deallocation functions and techniques include: “free”, “delete”, etc.
Proper memory allocation and deallocation are critical to preventing memory leaks, improving program performance, and ensuring efficient use of memory resources. Failure to deallocate memory can lead to memory leaks, where the program consumes increasing amounts of memory over time, potentially causing it to crash or become sluggish
What is a Memory Pool?
A memory pool, also known as a memory allocator or a memory management pool, is a software or hardware structure used to manage dynamic memory allocation in a computer program. It is a common technique used to efficiently allocate and deallocate memory for data structures and objects during program execution. It is a pre-allocated region of memory that is divided into fixed-size blocks. Memory pools are a form of dynamic memory allocation that offers a number of advantages over traditional methods such as malloc and free.
A memory pool is a logical division of main memory or storage that is reserved for processing a job or group of jobs
