 In computer networks, several devices help connect and share data between systems. Among them, Hub and Switch are two key connectivity devices used alike data transmission. A hub is a basic device that sends data to all connected computers, anyway of the place. In contrast, a switch is more intelligent it identifies each device’s MAC address and sends data only to the intended recipient. Understanding the difference between a hub and a switch is important like designing a secure and efficient network. In this article, we’ll discuss the difference between a hub and a switch, two basic yet important devices used in computer networks. Even they may look alike; they work totally differently when it comes to handling and send data. Know how each device functions helps in building a faster, more effective, and secure network system. What is Switch in Networking? A switch is a smart networking device used to connect multiple computers or devices within the same network. It manages the f...
