Web6 feb. 2024 · A hub is a very simple device that does virtually no processing and simply forwards the packets it receives. It does not read or inspect the data contained in the packets. On the other hand, a layer 2 switch has the processing power to look at the packets to know the destination and the source. WebDevices within the same VLAN and IP subnet can communicate at Layer 2 without any additional components. However, if a device on VLAN 10, for example, wants to communicate to a device on VLAN 20 -- this is known as interVLAN routing -- it requires a router that operates at the network, or Layer 3, segment of the OSI model. fed to taper bond buying https://sproutedflax.com
