1. 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.
Options
A. Network collisions occur
B. Repeaters cannot increase the signal strength sufficiently
C. Cable terminators do not reflect the signal properly
D. Cable terminators do not absorb the signal properly
E. "Line echo" occurs due to the impedance of the cable
A. an error-detecting code based on a summation operation performed on the bits to be checked.
B. a check bit appended to an array of binary digits to make the sum of all the binary digits.
C. a code in which each expression conforms to specific rules of construction, so that if certain errors occur in an expression, the resulting expression will not conform to the rules of construction and thus the presence of the errors in detected
D. the ratio of the number of data units in error to the total number of data units
