NUM LOCK Meaning and
Definition
-
Num Lock is a computer keyboard key that allows users to switch the functionality of certain keys, usually the keys on the right side of the keyboard, between acting as numerical keys or other functions such as cursor movement or page scrolling. When the Num Lock key is activated or "on", the numerical keypad on the right side of the keyboard will work and typing numbers becomes possible.
The Num Lock key acts as a toggle switch, where pressing it once activates the numerical keypad mode, and pressing it again deactivates it. Most modern keyboards display a small LED light indicating whether the Num Lock is enabled or disabled.
The primary purpose of Num Lock is to provide convenience and efficiency for numerical data entry. When working extensively with numbers or performing calculations, engaging the Num Lock allows for faster and more accurate input. Additionally, the Num Lock key allows the user to utilize the extra functions of the keys on the right side of the keyboard, such as the numerical keypad's ability to act as arrow keys or page navigation keys when Num Lock is turned off.
Overall, Num Lock is a key on a computer keyboard that enables or disables the numerical functionality of certain keys, providing users with the flexibility to switch between numerical input and other functions.

Etymology of NUM LOCK
The term "Num Lock" is a conjunction of two separate words: "num" and "lock". Each word has its own etymology.
1. "Num" is short for "number", which itself originated from the Latin word "numerus" meaning "number". The term was adapted into Old French, Middle English, and ultimately modern English as "number", referring to a mathematical value or a symbol representing a quantity.
2. "Lock" traces its roots back to the Old English word "loc", meaning "barrier" or "fastening". The word evolved throughout Germanic languages and eventually became "lock" in modern English. The term is commonly associated with securing or enclosing something.
In the specific context of computer keyboards, "Num Lock" refers to the function that locks the numeric keypad, allowing it to function as a numeric keypad rather than directional arrows.
