What Is the Difference Between Asterisk (*) and Wildcard Characters in Computing?

Learn the key difference between an asterisk (*) and wildcard characters, and how they are used in programming and search queries.

110 views

The difference between an asterisk (*) and a wildcard character in most computer and programming contexts is subtle but distinct. An asterisk (*) is often used to represent any number of characters, including none, in search queries and file searches. On the other hand, a wildcard character can vary in meaning based on the specific context or programming language but generally represents a single character space. In essence, an asterisk can stand in for a whole word or phrase, while wildcards usually substitute for just one character.
