. The bus is the data link in a bus network. The bus can only be transmit data in one direction, and if any network segment are severed, all network transmission ceases. A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic (traffic), and the traffic generated by each station have equal Tran Smission priority. Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable

(fiber) Radio waves (Wireless Raido) Coaxial cable:Coaxial cable is an early-use transmission medium, the standard of coaxial cable is divided into two kinds, 10base2 and 10BASE5. Both standards support 10Mbps transmission rates, with a maximum transmission distance of 185 meters and 500 meters respectively. Coaxial cable use for 10BASE5 and 10BASE2The diameter of the coaxial cable is 9.5m

? First look at a relatively old but popular standard: 10base5, an Ethernet standard, which is used to use a base band local network with a coarse coaxial cable and a speed of 10 Mbps. In a bus network, the maximum transmission distance is 500. The network node is equipped with a transceiver that is inserted into the 15-pin connection unit interface on the NIC and connected to the cable. It also serves as thick Ethernet, thicknet, and thickware. See a

requirement, the distance between A and B is critical, that is to say, the back-and-forth time for signal transmission between A and B must be controlled within a certain range. IEEE defines this standard. In a collision domain, the round-trip time between the farthest two machines must be less than 512bit time. (when the back-to-back time is less than 512 bits, the so-called bit time is the time required to transmit a bit ). This is also the diameter of a collision domain. When there are 512 b

Chapter 3 LAN principlesLAN technology mainly corresponds to the physical layer and data link layer of the OSI reference model, that is, the network interface layer of the TCP/IP model. The physical layer of a LAN specifies the physical and electrical properties, mechanical properties, and connection labels of devices, cables, and interfaces that provide services to the LAN. Common such standards include: For 10BASE5 coaxial coarse cable and transceiv

, all of the equipment must be connected to this wire using the BNC connector, which is what we often call the general linear physical topology. Coaxial cable internal structure In the network of the total line topology, the signal is sent from the sending machine to both ends of the cable, so there is a need for grounding at the end of the structure. By using grounding, the signal is not reflected back to the cable. If the grounding is not installed, the cable will produce duplicate e

coarse cable with a diameter of 0.4 cm adopts the drilling joint connection method, and RG-58 fine cable with a diameter of 0.2 cm adopts the T-head connection method. The crude cable must comply with the 10BASE5 media standard. An external transceiver and transceiver cable is required for use. The maximum length of a single device is 500 meters, which is highly reliable and can connect up to 100 computers, the minimum distance between the two comput

, large coverage, and mature CATV. Disadvantages: modem is required, which is expensive; installation and maintenance are complicated; transmission delay is doubled. 4.1.4 IEEE 802.3 Local Area Network (1) IEEE 802.3 is a LAN that supports the CSMA/CD algorithm. The most common baseband IEEE 802.3 lan has four types: n bsp; A. 10base5 (backbone network, crude cable) B. 10base2 (cheap, thin cable) C. 10base-t (easy to maintain) D. 10base-f (optical fi

Recently, Cisco's switching is needed because of work. Of course, it is also the technology of switching. Simple operations have been completed in general work, but recently it was found that network performance is very low in a large-scale integration test. If the test line is on one line, the other won't be able to run. Looking for someone from another ccnp department, we found that the loop in the settings appeared. However, after the loop is solved, it still cannot work. So it is in debug. I
