Final answer:
Wild card bits are also known as don't cares and are used to represent any possible value or combination of values in computer science and digital logic design.
Step-by-step explanation:
Another name for wild card bits is don't cares. In computer science and digital logic design, wild card bits or don't cares are used to represent any possible value or combination of values for a given bit or group of bits. They can be useful in simplifying Boolean expressions and reducing the number of constraints in truth tables.
