What Is A Network Switch And How Does It Work? - Tech Terms Explained

What Is A Network Switch And How Does It Work? Have you ever wondered how devices in a local network communicate efficiently without causing confusion? In this video, we’ll explain the role of a network switch and how it manages data traffic inside a network. We’ll start by defining what a network switch is and how it differs from older devices like hubs. You’ll learn how switches use unique identifiers called MAC addresses to send data directly to the intended device, making your network faster and more organized. We’ll also explore different types of data transmission, including unicast, multicast, and broadcast, and how advanced switches can perform routing between different networks. Additionally, we’ll discuss how switches operate in full-duplex mode, allowing simultaneous sending and receiving of data, which maximizes speed and efficiency. We’ll highlight the importance of switches in homes and offices, as well as their role in larger setups where multiple switches connect to a router for internet access. Moreover, we’ll cover modern features like Power over Ethernet (PoE), which supplies power to devices like security cameras and VoIP phones through the same cable used for data. Whether you're setting up a small home network or managing a large data center, understanding how switches work is essential for keeping everything running smoothly.
