What role does a router play in a network?

• A. Provides power to devices
• B. Directs data packets between networks
• C. Monitors internet usage
• D. Encrypts data for security

Answer: (B)

A router plays a crucial role in networking by directing data packets between different networks. It acts as a traffic manager, determining the best path for data to travel from its source to its destination. This involves forwarding information across interconnected networks and ensuring that data reaches the correct device or system efficiently. Routers analyze the destination address of incoming data packets and utilize routing tables or protocols to make informed decisions about the most efficient route. In contrast, the other options highlight functionalities that routers do not primarily handle. Providing power to devices is typically a function of power over Ethernet (PoE) devices, while monitoring internet usage pertains to network management tools rather than the router itself. Encrypting data for security is usually the responsibility of security protocols and software, not routers, which primarily focus on directing traffic rather than securing it.
