Alphanumeric refers to a set of characters that includes both alphabets (A-Z, a-z) and numbers (0-9). The term is often used to describe a combination of these characters, usually found in passwords, computer programming, data entry, and other digital contexts.
The concept of alphanumeric originates from combining the words "alphabet" and "numeric," emphasizing the inclusion of both alphabetic and numeric characters. This category of characters is frequently used in computer systems and databases as it allows for a wider range of information representation.
In computing, alphanumeric characters are typically encoded using the American Standard Code for Information Interchange (ASCII) or the Unicode character sets. These character sets assign a unique numerical code to each alphanumeric character, facilitating their storage, processing, and transmission in digital systems.
The use of alphanumeric characters is common in various aspects of technology, from creating secure passwords that combine letters and numbers to inputting data in software applications. Alphanumeric sequences may also be utilized to label or identify items, such as alphanumeric codes used in product serial numbers or vehicle identification numbers (VINs).
Overall, the term "alphanumeric" represents the combination of alphabetic and numeric characters and is essential in numerous technological applications that require a broad spectrum of information representation.
The word "alphanumeric" is derived from the combination of two words: "alpha" and "numeric".

- "Numeric" is a term formed from the word "numericus" in Latin, which means "pertaining to numbers" or "numeral".
The combination of these two words created the term "alphanumeric", which refers to a character set that consists of both alphabetical letters (A-Z, a-z) and numerals (0-9).
