What is a “router” in networking?
a) A device that directs data packets between different networks
b) A device used to encrypt data
c) A tool for monitoring network bandwidth
d) A method for compressing data
Answer:
a) A device that directs data packets between different networks
Explanation:
A router is a networking device that directs data packets between different networks, such as between a local network (LAN) and the internet (WAN). It helps ensure that data is sent to the correct destination by choosing the best path for the data to travel.
Routers are commonly used in homes and businesses to connect multiple devices to the internet, allowing them to share the same internet connection. They also provide features like NAT, firewall protection, and network security management.
By directing data efficiently, routers play a critical role in managing network traffic and ensuring reliable communication between devices.
