Which devices help our data travel across a network?

The correct answer is that switches and routers indeed play a significant role in helping data travel across a network.

Switches are intelligent devices that connect multiple devices within the same local area network (LAN). They use MAC addresses to forward data to the correct device, improving network efficiency and allowing multiple communications to occur simultaneously.

Routers, on the other hand, are used to connect different networks together, such as a home network to the internet. They determine the best path for data packets to travel from source to destination and can work with multiple data streams at once.

While switches and hubs are both used to connect devices on a local area network, hubs do not manage traffic intelligently; they broadcast data to all ports, which can lead to network congestion. Modems and firewalls serve different purposes, where modems connect networks to the internet and firewalls protect networks from unauthorized access. Repeaters and access points are used to extend network coverage but do not manage data routing in the same way that switches and routers do, making switches and routers the key devices for data travel across networks.
