What is a “router” used for in networking?
a) Directing data between different networks
b) Storing data
c) Encoding data for security
d) Printing documents
Answer:
a) Directing data between different networks
Explanation:
A router is a networking device that forwards data packets between different networks, ensuring that the data reaches its intended destination. It directs traffic on the internet by determining the best path for the data to travel.
Routers play a key role in both home and business networks, connecting local devices to the internet and other networks. They manage the flow of data, prevent network congestion, and enhance security by blocking unauthorized traffic.
Without routers, data would not be able to move efficiently between different networks, and users would have difficulty accessing websites and online services.
