Alfanumérico

Alfanumérico refers to a set of characters that includes both letters of the alphabet and numerical digits. This term is commonly used in computing, data entry, and cryptography. Essentially, an alfanumérico string or code can contain any combination of A-Z (both uppercase and lowercase) and 0-9. The specific set of characters considered alfanumérico can sometimes be extended to include certain punctuation marks or symbols depending on the context, though the core definition remains letters and numbers. For instance, passwords often require alfanumérico characters to enhance security. In database fields, alfanumérico data types are used to store text that may also include numbers, distinguishing them from purely numerical fields. When inputting information, systems often specify "alfanumérico" to guide users on the acceptable character types. This broad character set makes alfanumérico a versatile tool for creating identifiers, codes, and textual data that needs to incorporate both textual and numerical information.
