SCAN CODE Meaning and
Definition
-
A scan code, also referred to as a scan pattern or key code, is a digital representation of a specific alphanumeric or control character generated by a keyboard or barcode scanner. It is used to identify and communicate the input from a particular key or button.
In the context of keyboards, a scan code is assigned to each key and is used to uniquely identify the key pressed or released by the user. These codes are standardized and recognized by the computer's operating system. When a key is pressed, the keyboard generates the respective scan code which is then sent to the computer to determine the action associated with that key, such as typing a specific letter or executing a function.
Similarly, barcode scanners use scan codes to represent the information contained in a barcode. When the scanner reads a barcode, it translates the visual patterns into a digital format using scan codes. These codes are then sent to a connected computer or device to interpret and process the scanned information.
Scan codes are crucial for data entry and retrieval processes as they ensure accurate interpretation and translation of key/button presses or barcode scans. They serve as a standard language between input devices and computers, allowing seamless communication and interaction.

Etymology of SCAN CODE
The term "scan code" originates from the combination of two separate terms: "scan" and "code".
1. Scan: The term "scan" is derived from the late 14th century English word "scannen", meaning "to examine closely or with attention". It comes from the Old Norse word "skanna", which refers to the action of examining or inspecting closely. Over time, "scan" has come to mean the act of systematically examining or analyzing something, especially through the use of electronic devices such as scanners.
2. Code: The word "code" has its roots in the Latin word "codex", meaning "book" or "a system of laws". In the context of information technology, "code" refers to a set of rules or instructions used to represent or transmit data, often in a symbolic form.
