What are the connected devices of the LAN

The main technical parameters are bandwidth speed, bus mode, and electrical interface mode. Hub: Mainly refers to a shared hub.

It is equivalent to a multi-port repeater and a shared bus.

The variety of network devices is vast and growing day by day. Basic network equipment includes computers (whether they are PCs or servers), hubs, switches, bridges, routers, gateways, network interface cards (NICs), wireless access points (WAPs), printers, and modems.

Repeater Network Equipment A repeater is a local area network interconnection. Usually the host of the LAN is a microcomputer), a network adapter (also commonly known as a network card, used to realize the interface between the computer and the LAN communication), the transmission medium (used for the connection between the computer and the network equipment, it is the transmission medium that realizes high-speed communication.

In-network connectivity devices include network adapters, repeaters, hubs, transmission lines, and more.

Inter-network connectivity devices include bridges, routers, and more. The variety of network devices is vast and growing day by day.

The basic network equipment are: computers, hubs, switches, bridges, routers, gateways, network interface cards, wireless access points, printers, and modems. Repeater Positive Network Device A repeater is the simplest device for LAN interconnection, it works at the physical layer of the OSI architecture, it receives and recognizes network signals, then generates them and sends them to other branches of the network.

To ensure that the repeater works correctly, the first thing to do is to ensure that the packets and logical link protocols are the same in each branch. Gateway: The gateway repackages the information in order to adapt it to the requirements of the target environment. Gateways can interconnect heterogeneous networks, where the gateway reads data from one environment, strips the data of old protocols, and then repackages it with the protocols of the target network.

One of the more common uses of gateways is to translate between a microcomputer and a small or mainframe in a local area network.

Dear users, a LAN refers to a computer network in a small area, usually in a building or a geographically small area. The basic network connection devices for a LAN include the following:

1.Router: A router is one of the most important devices in a local area network, which can connect multiple devices to achieve communication and data transmission between devices.

The router can also implement Network Address Translation (NAT), which converts private IP addresses in the LAN into public IP addresses, so that devices in the LAN can access the Internet.

2.Switch: A switch is a device used to connect multiple devices in a local area network, which can achieve fast communication and data transmission between devices. The switch can also send data packets** to the target device based on the MAC address, improving the network transmission efficiency.

3.Network hub: A network hub is a relatively simple network connection device, which can connect multiple devices to achieve communication and data transmission between devices.

However, the network hub has a slower transmission speed and is not able to send packets to the destination device based on the MAC address.

4.Network network card: network network card is a device used to connect to the network in computer sensitivity, which can connect the computer to the local area network to realize the communication and data transmission between the computer and other devices.

In short, the basic network connection equipment of the LAN includes routers, switches, network hubs, and network network cards. These devices serve different roles, but they are all important components for communication and data transmission between devices within a local area network.

2. The switch is the most common device in the LAN, which can connect multiple computers, and can realize the transmission efficiency of the LAN by realizing the transmission of data packets; The router can be connected to different LANs to realize data exchange between different LANs. The Excited Bridge can connect different LANs to realize the transmission and sharing of data.

3 The functions of these devices are different, but they are all basic network connections to computers in a local area network.

2. The switch can realize data exchange between multiple computers and improve the efficiency of network transmission; The router can realize the data exchange between different networks and realize interconnection; A network card is a necessary component for computers to connect to a network.

3 In addition, there are some other network connectivity devices, such as hubs, bridges, etc., but their use has gradually become obsolete.

The basic network connection equipment of LAN includes routing attitude embedding devices, switches, network cards, webcams, and wireless APs. Routers are used to connect multiple networks and can connect the local network (LAN) with the Internet (WAN); Swap which machine can connect to a computer in the local network; A network card can connect a computer to a network; The webcam can monitor the liquid socks scene in real time; Wireless APs, on the other hand, can provide wireless connections to the network, making the network wireless.

The basic network connectivity equipment of a LAN includes switches, routers, modems, gateways, and hubs.

The commonly used devices of LAN include network card, hub, and switch, which are described as follows:

1. Network card: responsible for the electrical connection between the computer and the network medium, the transmission of the bit data stream and the confirmation of the network address, the main technical parameters are bandwidth speed, bus mode, and electrical interface mode;

2. Hub: mainly refers to shared hubs. It is equivalent to a multi-port repeater, which is obviously a shared bus, and can achieve simple encryption and address protection. Bandwidth speed, number of interfaces, intelligence, and scalability are mainly considered.

3. Switch: refers to a switching hub. Switches are created to improve the performance of the original network while protecting the original investment, reducing the network response speed and improving the network load capacity.

Switch technology is constantly updated and developed, and the functions are constantly intensified, which can realize network segmentation and virtual subnet division.

Network devices refer to physical entities connected to a network, including hubs, switches, bridges, routers, gateways, wireless access points, network cards, and modems. LAN refers to the network equipment used in large numbers at the physical layer and data link layer, including repeaters, hubs, bridges, and switches.

Packets are sent from one NIC to another, and the address of the NIC is the sending and receiving addresses of the packets, that is, the MAC address. Each NIC has a MAC address, with a length of 48 binary bits, usually represented by 12 hexadecimal numbers, such as 00-0c-29-67-9c-3a, the first 6 hexadecimal digits are the manufacturer number, and the last 6 digits are the manufacturer's NIC production serial number. Similarly, a MAC address is the network adapter's ID number.

2.Repeaters. The repeater works at the physical layer of the OSI model and is used to regenerate digital signals to extend the length of the LAN segment and drive long-distance communication.

Repeaters are suitable for interconnecting two networks that are identical or between two network segments under the same network. The repeater can only work within the specified delay range, otherwise it will cause network failure. The use of repeaters has the advantages of extending the reliable communication distance and improving the network performance, but it also increases the network delay, and when the repeater fails, the two parallel vertical sections connected by the repeater will be affected.

A commonly used network device for LANs is an Ethernet switch. Ethernet switch is a switch based on Ethernet to transmit data, and Ethernet adopts a shared bus transmission ** local area network.

Ethernet switch is a switch based on Ethernet to transmit data, and Ethernet adopts a shared bus transmission ** local area network. Ethernet switches are structured in such a way that each port is connected directly to the host and generally works in full-duplex mode.

The switch can connect many pairs of ports at the same time, allowing each pair of hosts to communicate with each other to transfer data as if they were exclusive communications**.

Features:

1. Each port of the Ethernet switch is directly connected to the host, and generally works in full-duplex mode.

2. The switch can connect many pairs of ports at the same time, so that each pair of hosts that communicate with each other can transmit data without conflict like exclusive communication.

3. If the bandwidth from an interface to the host is 10Mbit/s, then the total capacity of a switch with 10 interfaces is 100Mbit/s. This is the biggest advantage of the switch.

Ethernet switches are the most prevalent applications. Therefore, the application field is very wide, and they can be seen in large and small local area networks. Ethernet switches typically have a few to dozens of ports, essentially a multi-port bridge.
