Computer Network review, computer network review materials During the interview, if the interviewer wants to examine how your computer network has learned, how can he ask about the TCP three-way handshake process? So, I started to review the computer network in October April 24. I had to review the computer

One NIC can choose different IP according to the network environmentSometimes we encounter a situation where, when participating in a company project, the network environment does not have a DHCP service, the IP configuration must be specified manually, and when we go home from work, we must change the IP configuration in order to properly surf the internet. In fact, both Windows and Linux support the confi

Win8.1 system The lower right corner of the network icon shows "unrecognized network" how to resolve First, dial-up Internet access Direct dial-up access to this fault, for the machine can not obtain IP address (broadband connection is using the PPPoE protocol connection extranet, the local connection is using the TCP/IP protocol.) The physical connection to the local connection is correct when dialing,

Due to recent business needs, a function to get all the IP in the network segment is written, as well as a function to allocate the available subnet segments/** * Calculate all IP * @param string $segment network segment ' 139.217.0.1/24 ' * @return array IP list [' 139.217.0.1 ', ' 139.217.0.2 ' ...] According to the network segment. */functionGetipbysegment ($s

The clone source's Centos7_1 network address is 192.168.140.11, and I want to change the network address of the cloned centos7_2 to 192.168.140.12. Two places need to be changed: The network configuration of the virtual machine and the Centos7_2 configuration file.If you don't know how to configure a static address, you can view the previous article:1.

I. Introduction to the ConceptNetwork programs are divided into server-side programs and client programs. The service side is the one that provides the service, and the client is the party requesting the service. But the reality is that some programs of the client, server-side role is not so obvious, that is, mutual client and service side. When we write a network program, it is generally based on TCP protocol or UDP protocol for

Each time information is shared and transmitted with intranet users, "Network neighbors" will be used. Of course, by default, the system's "Network neighbors" function is very limited, if you want to share the transfer with your friends on the Intranet more efficiently and securely, you must find ways to tap into the potential of "Network neighbors. This is not t

IPV4 Address:We know that at the network layer (the Internet layer of TCP/IP architecture), one of the most important protocols is IP protocol, is now in the IPV4 and IPv6 transition period, but at present, IPV4 is still mainstream, so the main Ipv4.Basic IP Address format:The format of the internal IP address of the computer is represented by a 32-bit binary number, in order to make people seem convenient, usually using dotted decimal to represent th

But what do you do if you want to pass a data between the two programs?This problem can be solved with your knowledge now, we can create a file, write the content that a.py want to pass to the file, and then b.py to read the content from this file.But what do you do when your a.py and b.py are on separate computers?Simila
