What does it mean when a computer program is "multi-threaded"?

1. It calls multiple external libraries

2. It has multiple serial numbers for different users

3. It can run multiple chunks of code concurrently

4. It has multiple functions defined in the program

The correct answer is: It can run multiple chunks of code concurrently

When a computer program is described as "multi-threaded," it refers to its ability to run multiple chunks of code concurrently, allowing tasks to be executed simultaneously rather than sequentially. This concurrency can lead to more efficient use of system resources, as the program can perform multiple operations at once, improving performance and responsiveness, especially on multi-core processors. Multi-threading is particularly advantageous in applications requiring significant processing power, as it can handle tasks such as background operations, user interface updates, and heavy computations effectively without causing delays. The other options do not accurately capture the meaning of multi-threading. While calling multiple external libraries or having multiple functions defined in a program may involve certain complexities, they do not inherently relate to the concurrent execution of code. Having multiple serial numbers for different users speaks to software licensing rather than execution processes and has no relevance in determining a program's threading capabilities.
