Final answer:
In a computer program, a change to one component can have significant impacts on the functionality of the entire program.
Step-by-step explanation:
In a computer program, if there is a change to one component, it can have a significant impact on the functionality of the entire program. This is because components in a program often interact with and depend on each other. If one component is changed, it can lead to errors or unexpected behavior in other parts of the program.
For example, let's say you have a program that calculates the total price of a shopping cart. If there is a change to the component that calculates the tax, it can affect the final price calculation. If the tax component is not updated correctly, it could result in incorrect total prices for all the items in the shopping cart.
Therefore, it is important to carefully consider and test any changes to program components to ensure they function correctly and do not negatively impact other parts of the program.
