The difference between a repeater and a hub

1. A repeater (repeater)
   repeater is a network device located on layer 1th (the physical layer of the OSI Reference Model). When a data departure source is transmitted over the network, it is converted to an electrical pulse or a light pulse that travels along the network medium-these pulses are called signals (signal). When the signal leaves the workstation, the signal is planned and easily recognizable. However, as the signal travels along the network medium, the signal becomes weaker and worse as the cable becomes longer. The purpose of repeaters is to regenerate and redirect network signals at the bit level so that they can transmit longer distances over the network.
2. The purpose of the hub hub
    is to regenerate and reset the network signal. Its characteristics are similar to repeaters (known as multiport Relays Multiport repeater). A hub is a common connection point for each device in a network and is typically used to connect segments of a LAN. The hub contains multiple ports. When each group reaches a port, it is replicated to all other ports so that all of the groupings are visible to all LAN segments. The hub does not recognize any information patterns in the signal, address, or data.
    the difference between a repeater and a hub is the number of cables connected to the device. A repeater typically has only two ports, and a hub typically has 4 to 20 or more ports.
