Computer Networking Ethernet networks can be cabled in a number of topologies, depending on what works best in each environment. As more nodes are added, the efficiency of Ethernet decreases. Select the best answer as to why Ethernet becomes less efficient as size increases. Network collisions occur Cable terminators do not reflect the signal properly Repeaters cannot increase the signal strength sufficiently Cable terminators do not absorb the signal properly "Line echo" occurs due to the impedance of the cable Network collisions occur Cable terminators do not reflect the signal properly Repeaters cannot increase the signal strength sufficiently Cable terminators do not absorb the signal properly "Line echo" occurs due to the impedance of the cable ANSWER DOWNLOAD EXAMIANS APP
