Final answer:
Non-runnable (blocked) refers to a state of a program where it cannot continue its execution due to certain conditions or dependencies not being met.
Step-by-step explanation:
In computer programming, the term "non-runnable" or "blocked" refers to a state of a program where it cannot continue its execution due to certain conditions or dependencies not being met.
For example, if a program is waiting for user input or for a network request to complete, it will be in a non-runnable or blocked state until the necessary input or response is received.
This concept is applicable to various programming languages and can occur in different scenarios, such as when using multi-threading or asynchronous programming.
