What technology does CSMA/CD relate to?

CSMA/CD, which stands for Carrier Sense Multiple Access with Collision Detection, is a network protocol that helps manage how data packets are transmitted over a shared communication medium, specifically in Ethernet networking environments. This technology is designed to reduce collisions, which occur when two devices attempt to send data simultaneously over the same network segment.

In CSMA/CD, before a device sends data, it listens to the network to determine if it is currently in use. If the channel is free, the device transmits its data. However, if a collision is detected during transmission—meaning two devices transmitted at the same time—the devices temporarily stop, wait for a random period, and then attempt to resend the data. This process helps to ensure that data packets are sent and received efficiently in Ethernet networks.

The other options do not pertain directly to CSMA/CD: wireless communication generally employs different protocols such as CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance), database management relates to how data is stored and accessed, and web development involves the creation of websites and applications, which is outside the scope of network transmission protocols like CSMA/CD. Thus, Ethernet networking is the correct context for understanding CSMA/CD.
