Hop count is ___
a. The number of routers the data packet must pass through to reach the destination network
b. A measure of the reliability of the link, typically in terms of the amount of errors
c. The time it takes for a data packet to travel from source to destination
d. The measured delay time in terms of clock ticks, where each tick is approximately 55 milliseconds (1?18 second)
a. The number of routers the data packet must pass through to reach the destination network
Explanation: Examples of route metrics are as follows:
• Hop count: The number of routers the data packet must pass through to reach the destination network.
• Reliability: A measure of the reliability of the link, typically in terms of the amount of errors.
• Bandwidth: Having to do with the data capacity of the networking link; a Fast-Ethernet 100 Mbps link has greater data capacity than a 10 Mbps Ethernet link.
• Delay: The time it takes for a data packet to travel from source to destination.
• Cost: A value typically assigned by the network administrator that takes into account bandwidth and expense.
• Load: Having to do with the network activity on a link or router.
• Ticks: The measured delay time in terms of clock ticks, where each tick is approximately 55 milliseconds (1⁄18 second).
