MEMORY ALLOCATION Meaning and
Definition
-
Memory allocation refers to the process of assigning portions of a computer's memory resources to specific programs or data structures. It is a fundamental aspect of memory management in computer systems, enabling efficient and organized storage and retrieval of data.
In most operating systems, memory allocation involves dividing the available memory space into separate sections, or blocks, to accommodate different programs or data. This division may be temporary, with the memory being allocated and deallocated dynamically as needed, or it may be static, with memory being allocated to specific programs or data structures during the system's initialization.
The process of memory allocation entails identifying the appropriate block of memory to assign, tracking its availability, and managing conflicts or overlaps between different memory segments. This requires data structures, such as linked lists or bitmaps, to keep track of allocated and free memory blocks.
There are various techniques employed for memory allocation, including stack allocation, heap allocation, and garbage collection. Stack allocation follows a Last-In-First-Out (LIFO) approach, where memory is allocated and deallocated in a strict order. Heap allocation, on the other hand, allows for flexible memory allocation and deallocation, often managed by the programmer. Garbage collection is a form of automatic memory management that relieves the programmer from explicitly deallocating memory.
Efficient memory allocation aims to optimize the utilization of available memory resources, minimize memory fragmentation, and ensure reliable and secure data storage. It plays a crucial role in the overall performance and stability of computer systems, particularly in multitasking environments where multiple programs are concurrently running.

Etymology of MEMORY ALLOCATION
The word "memory allocation" consists of two main components: "memory" and "allocation".
The term "memory" comes from the Latin word "memoria", meaning "memory" or "remembrance". It is derived from the Latin verb "memor", meaning "mindful".
The word "allocation" comes from the Latin verb "allocare", meaning "to place" or "to assign". It is formed by combining the prefix "ad-" (meaning "to" or "towards") with the verb "locare" (meaning "to place" or "to locate").
Therefore, the etymology of "memory allocation" can be understood as the act of assigning or placing blocks of memory in a computer system.
