, transport layer, Session layer, presentation layer, Application layer) Reference Model, the second layer is the data link layer. It contains two sub-layers, the previous layer is the logical link control (llc:logical link controls), the next layer is the MAC (media access control) layer we mentioned earlier, that is, the media access controls layer. The so-called medium (Media), refers to the transmission of the signal through a variety of physical environment. Commonly used network media incl

MAC address is in the media access layer to use the address, popular point is the physical address of the network card, now the MAC address is generally used 6-byte 48bit (in the early and 2-byte 16bit of the MAC address). As for MAC address, because we do not contact with it directly, so we are not necessarily very familiar with. In the OSI (Open System interconnection, open Systems Interconnection) 7-Layer Network Protocol (physical layer, Data link layer, network layer, transport layer, Sess

The local area network is the individual computer or the terminal, uses the communication line to connect each other, follows certain agreement, carries on the information exchange, realizes the resource sharing. Among them, communication lines, that is, transmission medium commonly used: twisted-pair, coaxial cable, optical fiber and so on. From the cost-performance and maintainability, most LANs use unshielded twisted pair (utp-unshielded Twisted Pa

types and uses of network cables Network cable is our life in the LAN, WAN, the essential media, in the life of our common network cable mainly: twisted-pair, coaxial cable, optical fiber of these three kinds. The twisted pair is the most common in our life, and is also the main object of this article. Twisted pair is a data transmission line composed of many pairs of wires, which is characterized by its low price, so it is widely used. With the popu

Some knowledge about storageAccording to the different transmission protocols, the network card can be divided into three kinds, one is the Ethernet card, the second is the FC network card, the third is the iSCSI network card. Ethernet Card: The Scientific name Ethernet Adapter, the transmission protocol for the IP protocol, generally via fiber optic cable or twisted pair with Ethernet switch connection. The interface types are divided into optical and electrical ports. Optical ports ar

Basic knowledge of network programmingWhat is called computer network, is the distribution of computers in different geographical regions and specialized external equipment communication lines interconnect into a large-scale, powerful network system.The computer network mainly can do the following functions:1) resource sharing2) information transmission and centralized processing3) Balanced load and distribution processing4) Comprehensive Information ServicesThe computer network is divided accor

distance connection, -Typical path of a distance telephone A variety of transmission media is used in the telephone system. Now, the local loop is made up of 3 twisted pairs, whereas in the early days of the telephone industry, two of the wires on the telephone were not insulated from the 25cm. In the Exchange Bureau, coaxial cable, microwave, especially the fiber KFC is widely used 5 In the past, the signals transmitted throughout the telephone s

the data link layer more complex. 5. Physical layer (physical layers)The units of data transmitted on the physical layer are bits. When the sender sends 1 o'clock, the receiver should receive 1 instead of 0. The physical layer therefore considers how much voltage is used to represent "1" or "0", and how the receiver recognizes the bits sent by the sender. The physical layer also determines how many root pins should be connected to the cable's plug and how each pin should be connected. Of course

1. Ethernet is initially based on coaxial cable. 1972 Invention, 1979 Xeroxinter and Dec presented Dix edition. 2. In 1983, the IEEE802.3 standard was presented. 3. CSMA/CD communication process, transmission-monitoring-jamming-random waiting-transmission. 4. Traditional Ethernet network Bridge to split the host, with the router to connect the network segment. 5. Switched Ethernet, usually the host is not connected, when the need for communication

Wireless local Area network (Wireless Lan,wlan), as its name suggests, is a data communication system that provides wireless peer-to-peer (such as PCs to PCs, PCs to hubs or printers to hubs) and point-to-point (such as LAN to LAN) connectivity. The WLAN replaces the twisted or coaxial line or fiber used in the regular LAN to transmit and receive data through electromagnetic waves. WLAN performs traditional network communication functions such as file

ONACCESSH1004 Optical Network unit of each information point, while providing users with a duplex 100M speed Internet access, CATV broadcast signal and telephone access The ONACCESSH1004 Optical Network Unit provides a single mode single fiber interface, a CATV 75ω coaxial cable RF interface and 4 10m/100m RJ45 interface, a RJ11 ordinary telephone interface, connected with the OnAccess2224 video multiplexing fiber switch CATV signal Transmission adop

, coaxial cable, twisted pair; a remote router is used to connect remote transmission media and requires appropriate devices such as telephone lines to be equipped with modems, wireless via wireless receivers, transmitters. The main task of the router is to find an optimal transmission path for each data frame passing through the router and to effectively transfer the data to the destination site. This shows that the choice of the best path strategy

. Whether twisted-pair connection, coaxial cable connection or fiber optic connection, it is necessary to use the network card to achieve data communication.The main work of the network card is to clean up the data on the network, and then to send the data to the net after decomposing it into a packet of the appropriate size. For the NIC, each network card has a unique network node address, it is the network card manufacturer in the production of the

The six standards that have been finalized have not only required the ability of the entire link to achieve six classes of performance, in order to protect the different businesses of the six products can be compatible with each other and replace, and the six standards require each device also through six classes of performance, six-class channel and six-class link test methods can use Portable network test instruments, Six types of components include: Six types of cable, six class of informatio

In recent years in China CATV Network development, the country has built more than 1500 cable TV stations, the number of users up to more than 80 million, in the national c

1. Overview With the development of information society, network technology has become more and more complex, and as the cornerstone of the network, keel-network cable appears more important. In the current network, there are three kinds of cable media: Optical cable, coaxial cable and digital twisted cable. This paper focuses on the application of the largest number of twisted cable. The twisted cable used in the data is the most commonly used tran
