Different meanings: A bridge is a bridge to establish a connection between one LAN and another LAN. A bridge is a device belonging to the network layer. A gateway is essentially the IP address of a network to other networks.

Repeaters of different levels: Repeaters are used as intermediate devices in the physical layer. Bridge: A bridge is used as an intermediate device at the data link layer. Routers: Routers are used as intermediate devices in the network layer. Gateway: Gateway is used as an intermediate device in the transport layer.

Different working levels: repeater, also known as repeater or amplifier, implements the physical layer protocol and is responsible for data relay in the physical layer; The bridge is responsible for data relay at the data link layer; The router is responsible for data relay in the network layer; The gateway is responsible for data relay above the network layer.

The bridge works at the data link layer, connects two LANs, and forwards frames according to MAC addresses, which can be regarded as the underlying router (the router works at the network layer and forwards according to network addresses such as IP addresses).

What exactly is a gateway? How to set the gateway correctly in different networks?

Gateways are also called gateways and protocol converters. Gateway is located at the transport layer to realize network interconnection. It is the most complex network interconnection equipment, and is only used for the interconnection of two networks with different advanced protocols. The structure of gateway is similar to that of router, but the difference is the interconnection layer.

A gateway is a device that uses different protocols to connect two network segments. The function of the gateway is to translate and convert data using different transmission protocols in two network segments.

Gateways are also called gateways and protocol converters. Gateway realizes network interconnection above the network layer, and is the most complex network interconnection equipment, which is only used for interconnection of two networks with different high-level protocols. Walking from one room to another is bound to go through a door.

The gateway used by the host now usually refers to the default gateway. How to set the default gateway A computer's default gateway can't be specified casually, but it must be specified correctly, otherwise a computer will send packets to computers that are not gateways, so it can't communicate with computers on other networks.

Gateways are also called gateways and protocol converters. Gateway realizes network interconnection above the network layer, and is the most complex network interconnection equipment, which is only used for interconnection of two networks with different high-level protocols. Gateway can be used for wide area network interconnection and local area network interconnection.

Router setting gateway is a computer system or equipment that plays an important role in conversion. Generally speaking, it is a "gateway" between one network and another, also known as a network checkpoint. Gateways are also called gateways and protocol converters.

What are the functions of bridges, gateways, routers, hubs, interrupters and modems, and where are their applications? ...

Function: The main function is to divide the conflict domain and reduce the broadcast traffic in the network. Usually, in some early large-scale networks, when the number of hubs is too large and the collision domain is too large, it will cause a broadcast storm. At this point, properly placing a bridge in the middle of the network can divide the conflict domain and reduce the possibility of broadcast storm.

It is a store-and-forward device that connects two LANs, and can be used to connect network systems with the same or similar architecture. Routers: They process data at the network layer, so they can easily interconnect different data link layers, such as token ring network segment and Ethernet segment. Bridges are usually more difficult to control than routers.

Bridges, routers, switches, hubs. The function is * * *. A bridge connects two LANs with different physical layers, different MAC sublayers and different rates. Such as 100 MB/s and 100MB/S LAN. Because it has the function of storage and transformation.

Bridge is a technology of forwarding frames, which can isolate conflicts according to MAC partition blocks. Bridges connect multiple network segments at the data link layer.

What is a gateway and its functions?

A gateway is a device that uses different protocols to connect two network segments. The function of the gateway is to translate and convert data using different transmission protocols in two network segments.

The gateway is used to connect devices of two network segments using different protocols. Its function is to translate and convert data using different transmission protocols in two network segments. Like a door. For a family, the door is the door, and for a country, the custom is the door.

Home gateway equipment is a convenient, flexible, standard and highly integrated ADSL 2+ integrated access equipment, and it is a high-end integrated home gateway product conforming to IEEE80 1 1b/g standard.

What is a gateway? Is it related to the router?

1. Summarize the relationship between gateway and routing: gateway is the foundation of network connection, and routing is the bridge of network connection. Gateway is the entrance and exit of the network (gateway has other functions, such as protocol translation), which defines the boundary of the network.

2. Devices connected to two different networks can be called gateways; And' router' generally refers to a specific kind of product that can realize route discovery and forwarding. The gateway is the default data exit. If your data doesn't know where to go, it will be reported to the default gateway.

3. In the local area network, all routes are used to access the network, so the gateway usually refers to the default IP address of the router. Ailutong industrial gateway is a gateway device that can work in harsh environment, never stop and transmit data remotely.

4. First of all,' gateway' is a big concept, not a product. As long as devices connected to two different networks can be called gateways; And' router' generally refers to a specific kind of product that can realize route discovery and forwarding, and the router can obviously realize the function of gateway.
