What is a Switch?

Switch Definition

A network switch is a device that connects multiple devices in a network. It helps these devices transmit data to each other. Switches operate at the data link layer, which is Layer 2 in the OSI model. It uses MAC addresses to determine the path of each message. Some switches can also operate at Layer 3, meaning they can transmit data between different networks.

Switch Function

Switches control how data is transmitted in a network. They learn the MAC address of each device and use it to send data to the correct destination. Here are some of the main functions of a switch:

1. MAC Address Learning: Switches remember the MAC address of each device and match it with the correct port.
2. Forwarding and Filtering: Switches only send data to ports with matching MAC addresses. This helps keep the network fast and clean.
3. Flooding: If a switch doesn’t know the MAC address, it will send data to all ports except its source port.
4. Loop Avoidance: Switches use the Spanning Tree Protocol (STP) to prevent network loops by closing redundant paths.
5. Buffering and Queuing: Switches temporarily hold data to handle busy network traffic and use queuing to determine which data to send first.
6. Broadcast and Multicast Forwarding: Switches send broadcast or multicast data to all devices in a group.

Tip: Switches keep the network clean and ensure data reaches the correct device quickly.

Switch Use Cases

Switches are crucial in both small and large networks. People use switches for many reasons:

• To build a local area network (LAN) in the office so that devices can share data.
• To connect computers, printers, servers, and storage devices, helping people collaborate better.
• To allocate independent bandwidth to each device, thereby speeding up network speeds and reducing latency.
• To enable users and devices to easily share resources and communicate with each other.
• To ensure that each device can send and receive data simultaneously without slowing down.

Switches help networks operate efficiently and support multiple devices connected simultaneously.

Difference Between PDU and Switch

PDU and Switch Function and Purpose

PDUs and switches play different roles in the IT field. A PDU takes power from one place and distributes it to multiple devices.
