Question
What is the primary function of a router in a
network?Solution
The primary function of a router is to route packets between different networks. Routers are responsible for forwarding data packets between devices on different networks, making decisions about the best path for data to travel based on various factors, including the destination address and network conditions. This capability is crucial for connecting local area networks (LANs) to wide area networks (WANs), enabling communication over the internet. Routers analyze the data's destination IP address, consult their routing tables, and determine the optimal next hop for the data packet. They also manage traffic within and between networks, providing essential functions like Network Address Translation (NAT) and firewall services for security. Thus, routers play a vital role in the architecture of modern networks by ensuring efficient and secure data transmission across diverse network infrastructures. Option A (To connect devices within the same local area network) - This function is typically performed by switches, not routers, which operate primarily at Layer 3 (Network Layer) of the OSI model. Option C (To amplify signals over long distances) - Amplifying signals is a function of repeaters or signal boosters, which enhance signal strength but do not perform routing functions. Option D (To serve as a storage point for data backups) - Data storage is not a router's function; it is generally the responsibility of servers or dedicated storage devices. Option E (To provide remote access to internal resources) - While routers can facilitate remote access, their primary function is routing packets between networks, not serving as remote access servers.
