What is the primary function of a router in networking?

• A. Connect local area networks
• B. Store data temporarily
• C. Encrypt data traffic
• D. Provide wireless access

Answer: (A)

The primary function of a router in networking is to connect local area networks (LANs) and facilitate communication between them. Routers operate at the network layer of the OSI model, utilizing routing tables and protocols to determine the optimal paths for sending data packets across multiple networks. By directing traffic between different networks, routers enable devices on one network to communicate with devices on another, making them essential components in both home and enterprise network setups. In addition to connecting networks, routers can also provide various auxiliary functions such as network address translation (NAT), which allows multiple devices on a LAN to share a single public IP address. However, the core role of a router remains focused on facilitating inter-network communication.
