Final answer:
The increase in the number of devices on a network mainly raises security challenges. It makes managing and securing the network more complex, exposing it to potential security threats. Additionally, power consumption concerns are heightened due to the active duty cycles of these devices.
Step-by-step explanation:
When using many devices on the same network, one of the key challenges is related to security. As the number of devices increases, so does the attack surface, making it more difficult to manage and secure each device. The reliance on proper network security protocols and measures becomes significantly more critical to prevent unauthorized access, data breaches, and other security threats. An increase in devices also demands more complex network configurations and potentially a greater workload on network administrators to ensure network integrity.
Other issues such as power consumption also arise with an increase in the number of devices. Devices that are constantly on and running can consume a lot of power, particularly if they have high duty cycles, or the proportion of time they are active as opposed to being in a standby or off state. This consumption is often proportional to the activity and processing power of the device. Thus, energy-efficient designs and power management strategies become crucial in networks with a large number of devices.
