Answer: The performance of a bus topology degrades with the addition of more computers due to increased collisions, higher network traffic, bandwidth constraints, greater latency, and maintenance difficulties. This makes bus topologies less scalable and generally only suitable for smaller, less data-intensive networking environments.

Reasons for Affect Bus Network Performance

• Data Collisions: Bus topologies can have­ problems with data collisions. Sometimes, two or more­ computers send information at the same­ time. When this happens, the­ir data crashes together on the­ bus. This damages the information. It also causes more­ network traffic.
• Network Traffic and Congestion: Each node on a bus network receives every packet transmitted, regardless of the intended recipient, creating significant data traffic. This situation worsens as more computers are added, leading to congestion.
• Bandwidth Limitations: The bus provides a fixed bandwidth that must be shared among all connected devices. More devices mean less bandwidth for each, slowing down transmission speeds, especially during high data traffic periods.
• Increased Latency: The more computers there are, the greater the competition for access to the bus. This competition can significantly increase network latency, as each computer must wait longer for its chance to transmit data.
• Maintenance Challenges: As more devices are added, maintaining and troubleshooting the network becomes more complex. Problems like a faulty node or poor connections impact the entire network and are harder to diagnose and resolve with many devices.
