CHECK CHARACTER Meaning and
Definition
-
A check character, also known as a checksum or verification character, is a specific component added to data to ensure its integrity during transmission or storage. It is used to verify that the data has been accurately and completely transmitted or stored without any errors.
Typically, a check character is a computed value based on the data itself, creating a unique identifier. This computation involves an algorithm that applies a mathematical function or formula to the data, resulting in a simple numerical or alphanumeric code. This code is appended to the data as an additional piece of information.
When the data is received or retrieved, the check character's algorithm is re-applied to the received data, excluding the check character itself. The computed value is then compared with the received check character. If they match, it verifies that the data has not been corrupted or modified during transmission. Conversely, if they do not match, it indicates that there has been an error or alteration in the data.
Check characters are widely used in various applications such as error detection in digital communication systems, network protocols, storage systems, and data entry validation. They provide a simple and efficient method to verify the accuracy and reliability of transmitted or stored data, ensuring data integrity and minimizing errors.

Etymology of CHECK CHARACTER
The word "check character" has a relatively straightforward etymology.
The term "check" comes from the Old French word "eschequier", which referred to a chessboard. In turn, the Old French word was derived from the Persian word "shah", meaning "king". The word "check" gradually developed its modern sense of verifying or inspecting something.
The word "character", on the other hand, has its roots in the Latin word "character", which meant a distinctive mark or symbol. This Latin word itself was derived from the Greek word "khárisma", meaning "a gift or grace". Over time, "character" came to mean a written or printed symbol used to represent a sound or an element of writing.
