What advantage does modularity offer in software development?

Modularity in software development refers to the practice of dividing a program into separate, distinct components or modules, each performing a specific function. The primary advantage of modularity is that it simplifies updates and maintenance. When a program is broken down into smaller, manageable modules, developers can modify or replace individual parts of the software without affecting the overall functionality.

This approach allows teams to work on different modules simultaneously, which enhances productivity and speeds up development. Furthermore, if a specific module needs to be updated or a bug needs to be fixed, developers can do so quickly without having to sift through the entire codebase. Such isolation of components not only facilitates easier troubleshooting but also allows for targeted testing, ensuring that changes can be validated effectively.

In the context of the other options, faster data processing can be influenced by many factors unrelated to modularity, such as algorithm efficiency or hardware capabilities. The reduction of user manuals is not a direct advantage of modularity; while it might lead to better-structured code that is easier to use, it does not inherently eliminate the need for documentation. Lastly, modularity is known for reducing complexity by breaking a large and complex system into smaller, more understandable parts, rather than increasing the complexity of the code.
