Which of the following is the correct definition of a router?
A. A router connects networks together isolating traffic within each network.
B. A router is any computer, printer, or other electronic device that could potentially communicate with another device over the network.
C. A router is the physical layout of the cables and devices on a network.
D. A router allows one computer or device to make requests on behalf of another over a network.
Correct Answer: A
Explanation/Reference:
Explanation:
When conditions require greater distances or an increase in the number of nodes/repeaters, then a bridge, router or switch can be used to connect multiple networks together. These devices join two or more separate networks, allowing network design criteria to be restored. Switches allow network designers to build large networks that function well. The reduction in costs of bridges and switches reduces the impact of repeater rules on network design.
Each network connected via one of these devices is referred to as a separate collision domain in the overall network.
