![]() One problem with hubs is the unnecessary traffic due to the spammy transmission process. Each incoming bit is replicated on all other interfaces.Ī hub is the easiest and least expensive way to construct a network of personal computers together. It does not have the software required to identify specific targets.Ī hub is essentially an unintelligent device. A Hub does not differentiate between MAC addresses, and indeed cannot. What does an Ethernet hub do?Īn Ethernet Hub connects broadcasts signals to computers within a Local Area Network (LAN) through a process called frame flooding, also known as unicast. Now that you understand the route a signal travels and the address of the computer receiving, let’s look at how hubs and switches transmit to them. These addresses allow both hubs and switches to transmit data to a computer. Both of these can be found in that particular computer’s Network Interface Card (NIC). An IP address, on the other hand, is a software address. It’s either a 48-bit or 64-bit address given to a network adapter at the time of a computer’s manufacture.Ī MAC address is the hardware address for that device. The Open Systems Intercommunication (OSI) standards define layers as the model for communication over a network.įollowing are the layers over which Ethernet hubs and switches operate in-network functioning. Each device does this by targeting MAC addresses. ![]() Layers are the paths over which data is transmitted. A switch is complex, offering security, efficiency, intelligent function, and capability to transmit to specific in-network, MAC addresses over Layer-2 and Layer-3. A hub is basic, offering simple data transmission capabilities to MAC addresses over Layer-1. Ethernet hubs and switches are networking devices that connect computers together. ![]()
