The full form of COMPUTER is Common Operating Machine Purposely Used for Technological and Educational Research.
While the acronym is not universally accepted, this expansion explains the machine's functionality and purpose. It highlights the computer's versatility as a tool for a wide range of tasks, especially those related to technology and learning.
It is important to note that the word "computer" predates the invention of electronic computers. Originally, it referred to a person who performed calculations. The term was then applied to machines that automated these calculations. Therefore, the expansion above should be seen as a backronym (an acronym created to fit an existing word), rather than the original meaning.
