The quality of telephone lines or a crashed computer represents which type of barriers that affect communication with technology?

The quality of telephone lines or a crashed computer falls under physical barriers in communication. Physical barriers refer to tangible obstacles that hinder effective communication, such as faulty equipment, poor signal quality, or physical distance. When telephone lines are of low quality, it can lead to distorted sounds or incomplete messages, making it difficult for individuals to understand each other. Similarly, a crashed computer can prevent access to important information or disrupt communication channels entirely.

In the context of the question, physical barriers are concerned with the environment and technology used in communication. These barriers are particularly relevant in agricultural extension and communication, where access to reliable technology can significantly impact the effectiveness of information dissemination and interaction between agricultural professionals and farmers.
