What is the primary function of a router?

The primary function of a router is to forward data packets between networks. Routers are devices that manage traffic within a network and between different networks, directing data packets from one location to another based on the destination address embedded in the packets. They perform this task by determining the best path for the data to travel and efficiently directing it, ensuring that the information reaches the intended recipient.

A router connects various networks, which means it can link different segments of the internet or connect a local network to the internet. This capability is essential for enabling devices within smaller networks to communicate with devices in other networks and vice versa.

Other functionalities mentioned, such as connecting peripheral devices to a computer, processing data within a network, or storing data temporarily, do not accurately represent the primary role of a router. Peripheral device connections are typically managed by other types of devices (like hubs or switches), while data processing and temporary storage are related to computing devices or dedicated storage solutions rather than the fundamental routing role of a router.
