via the RJ45 cable to access the network, and the computer is set to "Automatically obtain IP address" and "Automatically obtain DNS address", which can be used as "broadband router" when "switch" use, Connect the network cable from the original computer to the LAN port on the router, and then make a network cable to connect the computer to the LAN port of the router (typically, the home broadband router has 4 LAN ports, 1 WAN ports), and the connect

does not power, so need external power. This excuse is mainly used for external hard drives. USB PLUS This is because the E-sata interface itself does not power, so there is the above figure of the USB plus interface, is the E-sata and USB2.0 combination, to solve the e-sata does not provide power supply defects, this excuse is common on the high-end motherboard. IEEE 1394 Interface IEEE 1394 Interface IEEE 1394, referred to as 1394. Originally developed by Apple, known as FireWi

Routers have a pivotal position in computer network, and are the bridge of computer network. It can not only connect different networks, but also choose the path of data transmission, and can block illegal access. The configuration of routers is not very easy for beginners. Now the general configuration of the router and simple debugging introduced to everyone, for friends in the configuration router reference, this article take Cisco2501 as an example. The Cisco2501 has an Ethernet port (AUI)

Vro interfaces are very important for network connection and routing functions. Here we will give a comprehensive explanation of vro interfaces and connection knowledge. A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more high-end router interfaces there are, the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration

channels are supported. The new-generation ADSL access technology supports up to four bearer channels and four delay channels, while the first-generation ADSL supports up to three bearer channels and two delay channels ). You can configure the frame structure latency and bit error rate (BER. The first generation of ADSL access technology has a fixed error code of 10. Because the BER is fixed, the line must maintain this BER indicator from start to end. Once the BER is greater than 10, the speed

Describes optical fiber access devices such as optical fiber jumpers.) in the Internet era, you may encounter Installation Problems of optical fiber access devices. The following describes the knowledge of optical fiber access devices, including how to connect DI-524M Wireless Broadband Router to your network and so on. Optical jumper Optical jumper A jumper is a cable pair or unit without a connector. It is used to connect various links on the distribution frame. Optical fiber Jumpers are used

200 min to ask if there is a grab kit to capture the crossdomain.xml request from Flash? Use Chrome or FF development tool can capture this request, but fiddler not, ask you heroes, thank you! ------Solution-------------------- It's better to give something out, or else you guys won't be able to test it. ------Solution-------------------- FIDDLER is a shrimp thing? If it's a bag-grab tool, it should be tougher than firebug. I'll take a look at the test address. ------Solution-----------------

proprietary wireless protocol developed wireless products. 2.4GHz type of wireless key mouse, generally plug in the computer's USB interface adapter, mouse and keyboard powered by the battery.2. Basic principles of wireless key mouseThe main difference between the wireless mouse and the Wired mouse is the way the signal is transmitted. Wired mouse uses wires to transmit information, while wireless keyboards use radio to transmit information. The early wireless keyboards used 27MHz bands, and th

meet the requirements of data transmission in Multi-Point media, the transmitter signal is not too weak, and the signal transmission requirements are not met in signal attenuation; or Excessive signals lead to Circuit overload and generate harmonic and other false signals. Therefore, for systems with N sites, to meet the preceding requirements, consider N * (n-1)/Two arrays. (4) Two transmission technologies: baseband transmission (full-frequency transmission of two-way digital signal transmiss

. Powerpctm structure processor consists of three modules: powerpctm kernel, System Interface Unit (SIU), and communication processor module (CPM ). All three modules adopt a 32-bit internal bus. The master processor of the MPC860 is a 32-bit powerpctm kernel that enables memory management (MMU) and command and data caching. In the system interface unit of the MPC860, the memory control unit supports a variety of high-performance memory, including SDRAM and flash, as well as a PCMCIA controller
