What are alphanmerics?

Answer 1

Alphanumerics are characters that include both letters (alphabetic characters) and numbers (numeric characters). They typically consist of the 26 letters of the English alphabet (A-Z, both uppercase and lowercase) and the digits 0-9. Alphanumerics are commonly used in various applications, such as passwords, usernames, and coding systems, to create more complex and secure identifiers. The inclusion of both types of characters allows for a greater variety of combinations and increases security against unauthorized access.
