e1:64k-2mbps. X25: The maximum rate is 64kbps. Frame Relay: Using E1 circuit, the rate can be from 64k to 2mbps. V24: The router end is a DB50 connector and the external network end is a 25-pin connector. In asynchronous working mode, the encapsulated Link layer protocol PPP, which supports network layer protocol IP and IPX, has a maximum transmission rate of 115200bps; In sync, you can encapsulate link layer protocols such as X.25, Frame Relay, PPP, HDLC, slip, and LAPB, and support IP and

10BASE-T: Twisted-pair cable, generally use rj-45 connector, the maximum effective transmission distance is from the hub 100m, even high-quality 5 twisted pair can only reach 150m. Its matching resistance is 120 euro. 10BASE5: Coarse coaxial cable, with insert-type joints, baseband signal, maximum support length of 500m, up to 100. Its matching resistance is 75 euro. 10BASE2: Fine coaxial

desktop computer, and there is no network card, you can buy a small USB external WiFi, plug in the desktop can also share WiFi. (As long as the PC can ping the IP on the phone) Check the phone-side connection to the PC side to share out the WiFi after assigning the IP, assuming it is 172.19.10.5, then open the command line on the PC side. Tap command adb connect 172.19.10.5. many times the first case will appear: " Unable to connect to 172.19.10.5:5555 ". What is this for? , because th

The horizontal twisted pair wires in the cabinet are located on the rear side of the Cabinet. In the past, the twisted pair wires were not organized or simply bundled before being immediately mounted to the distribution frame. At that time, from the back of the Cabinet, the horizontal twisted pair wires were hanging like waterfalls, or several nylon cable ties can be bundled on either side of the Cabinet. Everyone is concerned about the performance te

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 pa

When we use computers for work, study and recreation, what are the most feared things to encounter? I think there are a lot of users will say that the network has broken the problem, that is, the computer desktop in the lower right corner of the local connection shows the network cable did not plug the good tips, why this situation? A lot of XP SP3 system users will always inexplicably encounter this situation, but their network

the TCP/IP protocol, it turns out that there is no problem with the connections between the computers in segment 2, and network Segment 1, which is not just a break-through ping between the computers and the production machines, but also a ping between the other computers. The problem must be in net segment 1. The network Segment 2 to the production machine communication has the problem, is because from the network segment 2 to the production machine must pass through the network segment 1. Wh

1. The internal mechanism by which Linux performs write on the socket. It may involve some basic I/O mechanisms, and I can't figure out what's going on, running server and client separately, and then terminating the server so that client continues to write to the already established socket connection, and the first write successfully returns , the second execution process exits without any hint, and there's no return. Answer: After the server process is aborted, the socket is closed and fin is s

These two days the USB cable lost, always find colleagues to borrow also inconvenient, so on the internet to find a variety of methods, here summed up the simplest, of course, your phone needs root:1 to open WiFi, mobile phone and computer in the same LAN, this you can use your development machine to share WiFi can, I use the WiFi Sharing wizard, a button to do2 installing ADB Wireless on your phone3 after installing the ADB Wireless on your phone, pr

Android Developers all know that real machine debugging requires connecting the mobile phone to the PC, and then deploying the application to the real machine for installation and debugging. The long USB cable is troublesome, And it is inconvenient to connect the USB interface to other devices. Today, we will introduce a method for debugging a real machine without passing the USB cable. First, let the mobil

If you want external devices to access the local website, use the network cable to access the network connected by the route. if you want to ask a non-wireless network adapter, the local server will be connected by a wireless network card, an external device can access a local website through an automatically generated ip address, and the ip address becomes 192.168 after the network cable is connected throu

First, minicomFedora is not like the previous redhat, can not directly input minicom Enter, because there is no modem in the directory/dev/sub-directory, and minicom run by default is the directory, so the direct knock is not. But you can enter Minicom-s carriage return, so you can set the path of Minicom,/dev./modem to/dev/ttys0, and then set a soft connection, ln-s/dev/ttys0//dev/modem enter, you can. Then you can enter the minicom.Second, USB serial cableGeneral USB Serial line with the PL230

The premise is that your computer must be able to access the Internet.1. Enable the "file"-"connection settings" option in the synchronization software "Microsoft ActiveSync", remove "√" before "allow connection establishment through USB", and press OK.2. In the "Start"-"other"-"other"-"attachment" of the mobile phone, select "modem link", select "USB" in the "connection" column, select "Activate" in the "menu", and connect the phone and computer with a USB
