What type of device would have many network ports?

A switch is a networking device that typically has numerous ports to connect multiple devices within a network. It operates at the data link layer of the OSI model and efficiently manages data traffic between connected devices by forwarding data to the specific device that needs it, rather than broadcasting it to all ports. This capability not only reduces network congestion but also enhances performance by ensuring that devices receive the data intended for them.

Switches can range anywhere from a few ports to dozens or even hundreds of ports, making them suitable for large networks where many devices need to communicate with one another. For example, in a corporate environment, a switch can connect computers, printers, and servers, allowing them to communicate effectively.

In contrast, while routers connect different networks and may have multiple ports, they typically do not have as many as a switch. Hubs, primarily seen as older or less efficient devices, broadcast data to all connected ports rather than directing it based on MAC addresses, which is a less efficient method for handling traffic. Firewalls, designed to control incoming and outgoing network traffic, also do not usually emphasize the number of network ports as their primary function revolves around security rather than providing connectivity to a large number of devices.
