In TCP data link layer and physical layer are combined as a single host-to-network layer. The main thing that repeaters does is to REPEAT the signal from one side to other, it no taken on mind destination or something else, it just repeat the signal to the other ports. In the OSI model, it is the layer “closest to the end-user”. Gateways operate at the network layer of the OSI model. While gateway will settle for and transfer the packet across networks employing a completely different protocol. It is a repeater with additional filtering functionality based on reading the source and destination MAC addresses.

The lowest layer of the OSI Reference Model is layer 1, the physical layer; it is commonly abbreviated “PHY”. The device is a form of multiport repeater. If greater lengths are required for a network segment, devices known as repeaters may be added which sense and re-broadcast the Manchester-encoded FF signal between trunk cables. This layer is the protocol layer that transfers data between adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment. CAN bridges or switches (OSI layer 2) can be used to separate CANopen network systems into different segments, in order to limit impacts or to reduce busloads. With using of repeater, network can be scaled the size limit of a single, physical, cable segment. At this layer, the repeater receives the incoming signal and transmits it on the other side of the network segment. 1. It's employed to replicate the signal or information.
