How can the physical layout of a network affect its performance?

The physical layout of a network plays a crucial role in its performance because it can lead to signal interference and increased latency if not designed properly. When a network's physical components—such as cables, switches, routers, and access points—are positioned poorly, they can inadvertently create obstacles and sources of interference that degrade signal quality.

For example, if network cabling is run too close to sources of electromagnetic interference, such as power cables or electronic devices, these can disrupt data transmission, resulting in a slower network response. Similarly, physical obstructions like walls or furniture can weaken the signal strength in wireless networks. Poor spatial organization can also create longer paths for data to travel, increasing the time it takes for signals to be sent and received, thereby increasing latency.

Overall, the layout directly impacts how effectively data moves through the network and how quickly endpoints can communicate, emphasizing its significant influence on network performance.
