What is a flag?

In assembly language, a flag refers to a single bit or a group of bits that are used to indicate the status or outcome of a specific operation or condition. Flags are typically stored in a special register called the flag register or status register. These flags are set or cleared based on the result of arithmetic, logical, or comparison operations. They are used to control program flow, make decisions, and perform conditional branching in assembly language programming.
