Which component is primarily responsible for improving network traffic?

The correct answer is based on the role that each component plays in enhancing network efficiency and managing traffic. Firewalls are primarily security devices that filter incoming and outgoing network traffic based on predetermined security rules. While they help protect the network from unauthorized access and attacks, they do not directly optimize or improve the flow of network traffic.

Switches play a crucial role in network traffic management by directing data packets to their destination on a local area network (LAN), reducing collisions and allowing for efficient data transmission. They operate at the data link layer and use MAC addresses to forward data only to the intended recipient, which significantly enhances network performance.

Hubs, on the other hand, are basic networking devices that connect multiple Ethernet devices, making them function as a single network segment. However, they do not filter traffic or manage data collisions effectively, leading to higher traffic congestion compared to switches.

Routers are used to connect different networks and direct data packets between them based on their IP addresses. They operate at the network layer and distance traffic by making decisions on the best paths for data to travel, which is crucial for managing traffic across different networks.

In summary, switches are the primary component that improves network traffic within a LAN by efficiently directing data packets, while routers manage traffic between
