@etnetengineers: 1. Unmanaged Switch 🔌 These are basic "plug-and-play" devices that require zero configuration. Best for: Small home networks or basic setups where you just need more ports. 2. Managed Switch ⚙️ These are fully configurable devices used in large organizations. They allow for advanced security, monitoring, and traffic control. Key Features: Supports VLANs, QoS (Quality of Service), and deep network monitoring. 3. Layer 2 Switch 🤖 This switch operates at the Data Link Layer of the OSI model. It uses MAC addresses to decide where to send data packets within a local network. Best for: Fast internal communication within a single network segment. 4. Layer 3 Switch 🌐 These switches operate at the Network Layer. Unlike standard switches, they can use IP addresses to perform routing functions, much like a router would. Best for: Advanced enterprise networks that need to route data between different subnets. 5. PoE Switch (Power over Ethernet) ⚡ A specialized switch that sends both data and electrical power through a single Ethernet cable. Best for: Powering IP cameras, VoIP phones, and WiFi Access Points (APs) without needing extra power outlets. 6. Smart Switch 🧠 Also known as "Web-smart" switches, these are a middle ground between unmanaged and fully managed. They offer basic management features at a lower cost. Key Features: Limited VLAN and QoS support; very cost-effective for small businesses. #Cisco #ITEthiopia #Trunking #VLAN #Networking
