Hubs & Switches: The Backbone of Modern Networking

In the world of networking, the role of hubs and switches is often underestimated. These devices form the foundation of data communication in offices, data centers, and even home networks. While both hubs and switches are used to connect multiple devices in a network, they operate differently, impacting speed, security, and efficiency. Understanding how hubs and switches function can help businesses and individuals make informed decisions about their networking infrastructure.

What is a Hub?

A hub is one of the simplest networking devices. It connects multiple computers or network devices and allows them to communicate by sending data to every port connected. This means when one computer sends information, the hub broadcasts it to all connected devices, regardless of the destination. While hubs were widely used in early networking setups, their limitation lies in inefficiency. Broadcasting data to all devices causes unnecessary traffic, leading to network congestion and slower speeds. Hubs also lack advanced features like traffic management and security, which makes them less suitable for modern high-speed networks.
