What is a bus repeater? What for? Where is the application?

A repeater is a connected device on top of the physical layer of the network. It is suitable for the interconnection of two types of networks that are exactly the same, and the main function is to expand the distance of network transmission by resending or retransmitting data signals. A repeater is a network device that reproduces and restores signals

Physical layer devices for the OSI model.

The repeater is the simplest and cheapest network interconnection device used to extend the network distance in the LAN environment, operating in the physical layer of the OSI, the repeater has the function of amplifying and reproducing the signal on the ** road, and is used to extend the length of the LAN network segment (only used to connect the same LAN network segment).

The repeater (RP repeater) is a device that connects network lines, and is often used for the bidirectional work of physical signals between two network nodes. The repeater mainly completes the function of the physical layer, which is responsible for transmitting information bitwise on the physical layer of two nodes, and completing the function of replication, adjusting and amplifying the signal, so as to extend the length of the network. Due to the loss, the power of the signal transmitted on the ** road will gradually decay, and when the attenuation reaches a certain level, the signal will be distorted, so it will lead to reception errors.

Repeaters are designed to solve this problem. It completes the connection of the physical line and amplifies the attenuated signal to keep it the same as the original data. In general, the two ends of the repeater are connected to the same **, but some repeaters can also complete different ** transfer work.

Theoretically, the use of repeaters is unlimited, and the network can therefore be extended indefinitely. In fact, this is not possible, because the network standards have specific provisions on the delay range of the signal, and the repeater can only work effectively within this specified range, otherwise it will cause network failure.

Function: The repeater (RP repeater) works in the physical layer of the OSI and is the center of all nodes on the local area network, its role is to amplify the signal, compensate for the signal attenuation, and support long-distance communication. The repeater, which works at the physical layer, only plays the role of extending the transmission distance, and is transparent to the higher-level protocol.

In fact, a network connected by repeaters is equivalent to a larger network made up of the same wire. Repeaters can also connect networks of different transmission media (10base 5 and 10base 2) and are mostly used in the interconnection of the same LAN above the data link layer.

1 Repeater

A repeater is a network device that sits at Layer 1 (the physical layer of the OSI reference model). When data leaves the source and travels over the network, it is converted into electrical or optical pulses that can be transmitted along the network medium – these pulses are called signals. When the signal leaves the transmitting station, 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 passes through it gets longer and longer. The purpose of repeaters is to regenerate and retime network signals at the bit level, allowing them to travel longer distances over the network.

2 Hub

The purpose of a hub is to regenerate and retime network signals. Its characteristics are very similar to those of repeaters (known as multiport repeaters). A hub is a common connection point for individual devices in a network, and it is usually used to connect segments of a LAN.

The hub contains multiple ports. When each packet arrives at a port, it is copied to all other ports so that all LAN segments can see all packets. The hub is not aware of any patterns of information in signals, addresses, or data.

An RP repeater is a connected device that works on the physical layer. It is suitable for the interconnection of two types of networks that are exactly the same, and the main function is to resend or ** the data signal through the brother to expand the distance of network transmission.

A repeater is a network device that reproduces and restores signals: a physical layer device for the OSI model.

The repeater is used to extend the network distance in the local area network environment, but it does not belong to the network interconnection equipment, operating in the physical layer of the OSI, the repeater has the function of amplifying and regenerating the signal on the first road, which is used to expand the length of the LAN network segment.

The word repeater is defined as a connected device that works on the physical layer. It is suitable for the interconnection of two types of networks that are exactly the same, and the main function is to expand the distance of network transmission by resending or retransmitting data signals.
