Network Switches: The Backbone of Modern Connectivity
A network switch is a central device that connects multiple computers, servers, and other devices within a local area network (LAN), enabling them to share data efficiently. In today’s businesses, data centers, and smart homes, switches play a crucial role in ensuring seamless communication and stable internet performance.
What Is a Network Switch?
A network switch operates at the data link layer (Layer 2) or sometimes the network layer (Layer 3) of the OSI model. It receives data packets and intelligently forwards them only to the specific device or port that needs them, unlike a hub that sends data to all connected devices. This targeted approach improves speed, reduces congestion, and enhances security.
