Which of the following factors affects the performance of a data network?

The performance of a data network is influenced by a variety of factors, and all of the options presented play significant roles in this aspect.

Cable type and installation practices are crucial; different types of cables (such as fiber optic, coaxial, or twisted pair) have unique characteristics that determine bandwidth, latency, and overall data rates. Proper installation practices, including cable management, termination techniques, and adherence to standards, can minimize signal loss and crosstalk, thereby enhancing network performance.

The number of devices connected to the network also significantly impacts performance. As more devices are added, bandwidth is shared among them, which can lead to congestion and decreased efficiency. This is particularly important in environments with high demand for network resources, where excessive device count can saturate available bandwidth.

Environmental conditions and power supply are additional factors that can affect network performance. For instance, physical elements such as temperature, humidity, and electromagnetic interference can disrupt signals, while an unstable power supply can lead to outages or fluctuations that impact network reliability and performance.

Together, these factors—cable type and installation, the number of connected devices, and environmental conditions—create a holistic view of network performance. Thus, recognizing that all these elements are interrelated helps in understanding how to maintain and
