connections. Basic knowledge about wireless network AP ③ Wireless Router A wireless router must be a Wireless Broadband Router. A wireless router is a network device that can be connected to a LAN or a WAN and has both the broadband routing and Wireless AP functions. There are two types of wireless routers. One is an ordinary dual-port wireless router without an exchange module. One RJ45 port is a WAN port used to connect to broadband, and the other

' terminal devices. It must comply with the ISDN standard and can meet the high-speed data transmission standard. Iv. Copper Cabling System Design Scheme The copper cabling system consists of the workspace subsystem, horizontal cabling subsystem, vertical trunk subsystem, management subsystem, and inter-device subsystem. A. workspace Subsystem The workspace subsystem consists of information sockets, connection sockets, and connections of terminal devices installed in various office areas. Here w

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 Area, A network composed of a group of computers, servers, printers, and similar device connections. The various multi-host networks we currently use belong to this category. Each computer (or other network device) on the LAN h

This topic simply understands the content of the port;Brief introduction:"Port" is the translation of the English port, it can be considered as the export of communication between the equipment and the outside world.The ports can be divided into virtual ports and physical ports, where the virtual (protocol) port refers to the inside of the computer or the port within the switch router and is not visible.For example, 80 ports, 21 ports, 23 ports, and so on in the computer.The physical port, also

1.1 Application ScenariosThe interaction object of communication platform includes two aspects: first, interacting with hardware products. Second, interacting with software products. Basically these two aspects, communication platform will generally be used in two scenarios:1) Communication platform application on PCMainly used in the automatic station of the industrial computer, through rs485/rs232, RJ45, 4-20ma and other ways to collect data informa

Category 5 is 100 mb/s, while that of Category 5 is as high as 155 mb/s, which can meet the needs of multimedia data transmission in the future, therefore, Category 5 or more than Category 5 twisted pair wires are recommended. Twisted Pair wires can also be divided into shielded twisted pair wires (stp) and unshielded twisted pair wires (utp ). Although the stp twisted pair has a low speed (only 4 mb/s), its anti-interference capability is higher than that of utp twisted pair, so the price is m

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,

, 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

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
