How many meters does the network cable transmit at most? Several common categories of network cable and network cable transmission
Maximum network cable data transmission distance
If you know more about the network, you know that the twisted pair wires have an insurmountabl
UNIX network programming. Volume 1, Socket network API (version 3rd) (Chinese version) (the classic work of Steven s, two top network programming experts are invited to write a revision)
Basic Information

The general corporate network will be divided into the intranet (wired) and the external network (wireless), and the network access restrictions rules, resulting in some applications can not be used, this situation we want to be connected to the intranet, but also hope that some programs can access the extranet. What do we do? The following configuration can be u
The network cable is already inseparable from our life. Because we often use the network cable, we need the network cable to access the Internet. Therefore, we need to learn how to make the network cable so that we can better control our life in Russia,
Okay. Let's just talk about the
First, the production network
Advantages:
1, globalized, deployed in the Internet environment
2, the implementation of the code of the smart contract, block calls, can be clearly seen
3. A smart contract deployed in a production environment that can be called by any application in the world
Disadvantages:
1, any contract execution will consume the real etheric currency, that is, real cash, not suitable for development, commissioning and testing
It is recommended that you set the network card NAT mode
Dynamic Network configuration:
1, be sure to open the local DHCP service
2. Select the NAT mode in the Virtual network editor to select the DHCP entry as shown below
3, Ifup eth0Static network configuration:
Note: Ifcfg-eth0 part parameter description
Slow wireless network speed? How many times faster does the wireless network work? Try these tips !, Slow wireless network speed
In the modern Internet era, the first productivity is the speed of Network. We can't do without wireless networks every day. We need wireless networks at home and offices. However, if the s
LWIP Network Interface network card initialization to STM32 as an example will be useful after 2G or 4G module in the form of PPP dial-up virtual network card, so first of all, this is the premiseLWIP has a structure that describes the physical interface of the Netif Struct, the great god of Chu has a detailed explanation of this: http://blog.csdn.net/zhzht198610
network communication Mode
There are two kinds of existing network communication methods:
1.TCP (Transmission Control Protocol) mode
TCP is a connection-oriented reliability transport protocol, TCP is like a telephone, use this way to communicate, need to establish a dedicated virtual connection, and then reliable data transmission, if the data sent failed, the client will automatically resend the data.
2.U
the OSI model of network isolation viewed from network attack
On the network isolation, we must first talk about the security risks of the network. What is risk. Scan, attack, invade, Trojan and so onis risk. It can be difficult to describe all of the network attacks in a

We recommend that you set the nic nat mode.
Dynamic Network Configuration: 1. You must enable the local DHCP service.
2. Select the DHCP option in NAT mode in the virtual network Editor,

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
1. The share in the computer's local connection is disabled by the administrator. Try some methods on the Internet, it is not OK. Finally think about modifying the registry. I found the shared option in the registry. Modify 0 to 1. The sharing of local connections is implemented.2. But even then, the temporary network shared by the local connection still does not have a valid IP address, so it cannot be connected. Try assigning their addresses manuall

RNN (recurrent neuralnetworks, cyclic neural network)
For a common neural network, the previous information does not have an impact on the current understanding, for example, reading an article, we need to use the vocabulary learned before, and the ordinary neural network does not do this,
Oan (optical fiber access network): consists of at least one OLT, ODN, and ONU.
OLT: Optical line terminalOptical line terminal, which manages multiple terminal devices (ONU). It is also a device of the Internet portal and Intranet portal.Function: Provides network interfaces for optical access networks and communicates with the user-side ONU through one or more ODN. The relationship between OLT and ONU is

Ask a question, the local server, with the wireless network card network, the external device can be automatically generated by IP access to the local site, and through the network cable routed through the network, IP becomes 192.168 ... , the external access is not, how to solve this?
