DEALLOCATION Meaning and
Definition
-
Deallocation is a process in computer science and programming that involves freeing up memory or resources that were previously allocated or assigned to a program or process. It refers to the action of releasing or returning these allocated resources for reuse, making them available for other programs or processes to utilize.
In programming languages, such as C or C++, memory allocation is a critical aspect of managing system resources. Memory allocation occurs when a program requests and assigns specific memory blocks to store data or execute a particular task. However, after the data has been used or is no longer needed, it is essential to deallocate the memory to prevent resource wastage and potential memory leaks.
Deallocation involves the identification and release of memory or resources, allowing them to be reclaimed by the operating system or made available for reallocation. Efficient deallocation ensures that valuable system resources are not tied up unnecessarily and helps optimize the overall performance of a program or system.
There are different methods of deallocation, including explicit deallocation, where a programmer manually releases allocated memory using language-specific statements or functions. Another approach is automatic deallocation, usually handled by garbage collectors, which automatically identify and reclaim memory that is no longer in use.
Overall, deallocation is a crucial process in computer science and programming that enables efficient management of system resources, preventing resource exhaustion and maximizing the performance of programs and systems.

Etymology of DEALLOCATION
The word "deallocation" comes from the combination of two base words: "de-" and "allocation".
1. "De-" is a prefix that means the removal, negation, or undoing of the word it is attached to. In this case, it expresses the opposite of "allocation".
2. "Allocation" comes from the Latin word "allocare", which means "to assign" or "to distribute". It is derived from "ad-" (to) and "locus" (place).
When these two words are combined, "deallocation" refers to the act of freeing up or releasing allocated resources, such as memory or storage space, by reversing the assignment or distribution. The term is commonly used in computer science and programming to describe the action of releasing memory or resources that were originally allocated for a specific purpose.
