alphanumeric characters

Alphanumeric characters are the combination of letters (A-Z, a-z) and numbers (0-9). They are used in computers and coding to represent, store, and transmit information in both text and numerical formats. This set allows for a versatile way to create passwords, labels, or codes that are easy to read and remember. Alphanumeric characters are essential because they enable digital systems to distinguish different types of data, combine identifiers with numbers, and support complex information processing efficiently.
