adaptive NICs, the speed of the network adapter depends on the bandwidth of the network device connecting the other end. If the other end is connected to a m network device, the network connection will be switched to a m physical connection rate. It is worth mentioning that at present, Most laptop built-in NICs Support automatic adaptation of RJ45 568a and 568b in Two-line sequence, which makes it very convenient to create and find Ethernet connecti

I. SuperIO communication mechanism. SuperIO Communication Mechanism1.1 application scenarios Communication Platform interaction objects include two aspects: first, interaction with hardware products. 2. Interaction with software products. Generally, communication platforms are used in two scenarios: 1) The communication platform is applied to PCs. It is mainly used in automatic station industrial computer to collect data of hardware devices through RS485/RS232,

Use Cisco router reverse telnet to do Terminal ServerIf we have more than one router to do the experiment, if it is according to the control line of a single configuration will be very troublesome, so we need to configure a Terminal server to log on to other machines here, the following practices:Install the eight claw cable with Cisco 2509, and note that only the cables are installed and no DB25-RJ45 converters need to be mounted. Plug the eight claw

, such as Cisco's routers, are in this way to manage the device, a small console line is equivalent to a PC monitor plus keyboard, which undoubtedly saved the router a lot of unnecessary accessories, In fact, part of Cisco's equipment is a PC, such as Cisco PIX515 Firewall, as long as you plug in a PCI card to the PCI slot, connect the monitor, press the PIX switch, you can see an BX motherboard, Pentium II 350MHZ processor, 128M memory computer startup information, and a normal computer to star

The plastic fibre-optic departmental switch provides multiple Ethernet fibre ports, providing high-bandwidth, high-performance fibre connections between workgroups or workgroups. Plastic fiber Optic network card with Ethernet plastic fiber interface of the computer PCI card, in line with the IEEE Standard, Plug and Play, support Full-duplex mode. The POF-

or more Wan IP addresses, or public or Internet IP addresses. Generally, you must pay the ISP for the wan ip address before applying for it. The Wan IP addresses cannot be repeated. (WAN and LAN) the data exchange between computers must be converted through the NAT Network Address Translation of the router or gateway. Currently, the WAN Port provided by the wireless router is generally a 10/100 Mbps adaptive RJ45 port, which can be connected to devic

ADSL is currently the most mainstream broadband access method, while wireless is currently the most popular network access method. The encounter between the two will naturally attract the attention of many readers or users. Let's take a look at several forms of ADSL and wireless connections or Internet sharing, I believe you will have a better understanding of these two devices. ADSL is currently the most mainstream Broadband Access Method I. Overview of ADSL Devices A

comes with two cables for RJ45 sockets. If it is connected to the distribution frame of the 110 connection module, it is recommended that one end be connected to the RJ45 plug and the other end be connected to the 110P patch connection.A standard test report collects all data for connection performance tests in the ISO11801 standard. It should be noted that two operators with communication tools or walkie

optical fiber network products are mainly used to achieve high-speed network connection between working group switches and computer equipment in the LAN. The main plastic optical fiber network equipment is as follows. A Plastic Optical Fiber Department switch can provide multiple Ethernet Optical Fiber ports to provide high-bandwidth and high-performance Optical Fiber connections between Working Groups or working groups. The plastic optical fiber Nic has a computer pci nic with an Ethernet Plas

transmission bandwidth must reach MHz to reduce the effect of crosstalk between different wires, some new transmission parameters must also be defined; 2. The system needs to provide better insertion loss (attenuation) performance, so a thicker wire will appear; 3. More tests are required to determine whether the current system supports new applications; 4. design new cables to meet new performance requirements. In addition, there is a very important issue worth noting, that is, there is no ind

addresses cannot be repeated. The data exchange between a WAN and a LAN computer is performed through the NAT (Network Address Translation) of the router or gateway. Currently, the WAN Port provided by the wireless router is generally a 10/100 Mbps adaptive RJ45 port, which can be connected to devices such as xDSL and Cable MODEM or Ethernet. Common wireless route parameter 2 LAN port A Local Area Network (LAN) is a relatively limited geographical Ar

Super 6, commonly known as 6A, is a 10 Gigabit system. For testing, it is necessary to achieve a MHz test, divided into unshielded and shielded systems. For a non-shielded system, a 6 packet 1 External crosstalk test is required. Currently, FLUKE and ajelun both have this test instrument. The unshielded structure is currently popular on the basis of the six categories. The Twist distance is more dense and the wire diameter is thicker. The most important change is the change on the PVC outside, a

. Twisted Pair wires are divided into shielded twisted pair STP and Unshielded twisted pair UTP. Unshielded twisted pair wires have outer cables as shielded layers, which are suitable for scenarios with low network traffic. Shielded twisted pair wires have a sheath, which has strong resistance to Electromagnetic Interference EMI (Electromagnetic Interference) and are suitable for high-speed network protocol applications with large network traffic. Twisted Pair wires can be divided into 5 categor

consists of a long Twisted Pair wires and RJ45 headers. Currently, cable twisted pair wires are sold on the market ". Most users purchase three types of cables and five types of cables. Currently, cat5e and cat5e unshielded twisted pair 1 are used. The transmission performance is 100 MHz and the transmission rate is 155 Mb/s. In addition, these twisted pair wires have the following features: The diameter is small, saving the occupied space.Light Weig

Cabling Standards and are composed of cables, wiring boards, workstation sockets, and connectors at both ends of the channel. The Optical Fiber Channel consists of FDDI multi-mode optical fiber cables, wiring boards, workstation sockets, and connection wires at both ends. 1. Costs of unshielded twisted pair Structure The following equipment must be installed: 1) 100 cat-5e unshielded twisted pair Cable data cables from the network cabling room to 100 user terminal stations; 2)

At present, broadband routers and wireless routers are becoming increasingly popular in the household and small and medium-sized enterprise markets, and readers will find that both broadband routers and wireless routers, each of them has four adaptive RJ45 lanports and at least one adaptive RJ45 WAN port. What is the difference between a similar port and a vswitch? What are their features and how to use the
