As against, Repeater do not understand any frames/packet/bits. The Network Interface Layer adds the source and destination Internet protocol (IP) addresses, and forwards the packets to the Internetwork Layer. This is the one type of network device that functions at the OSI physical layer where it amplifies or regenerates the incoming signal before transmission. The medium access layer was made necessary by systems that share a common communications medium. So repeater is a signal amplifier used to amplify the low signal to high signals. In the TCP/IP Reference Model, a repeater uses this (these) layer (s) when carrying a conversation. It also characterizes the media type, connector type and signal type to be used for communication. As the explanation of one of them say: "Repeaters are protocol transparent". it cannot identify the destination of the packet, so it broadcasts or send the message to each port.

Bridges can work on a single broadcast network segment while repeater can forward all segment traffic. Bridge works in data link layer. 88 terms. C) physical. When the hub receives information from a sending device, it simply repeats, or broadcasts, that same information out all ports on the hub. At this layer, the repeater receives the incoming signal and transmits it on the other side of the network segment. Some people use the terms concentrator when referring to a passive hub and multiport repeater when referring to an active hub. At layer 3, the IP address is added to the packet. He determines that one device he requires must have the capacity to act as a repeater, operate at the Data Link Layer of the OSI model, be able to filter packets based on their MAC address, and allow communication between two local area networks (LANs). Layer 3 switch. This is what the internet actually runs on. 1[2] In the OSI model for computer networking, STP falls under the OSI layer-2. Repeaters are sometimes referred to as signal boosters. The switch stores MAC addresses and in the switch, multiple devices can send data at the same time. digital switch: A digital switch is a device that handles digital signals generated at or passed through a telephone company central office and forwards them across the company's backbone network.
