In the context of a computer program, a branch refers to an instruction that alters the default execution sequence. This means that instead of executing the next sequential instruction in the program, a branch allows the program to jump to a different part of the code based on specific conditions or logic. This is commonly seen in programming structures such as if-else statements, loops, and switch cases, where the flow of control can change depending on certain criteria.

For example, if a certain condition is met (like a variable exceeding a particular value), the program can branch to a different section of code to execute alternative instructions. This capability is crucial for implementing decision-making within programs, making them dynamic and responsive to user input or other variables during execution.
