The development of computer networks has come a long way. The various communication software we use today undoubtedly relies on computer networks. But do you know the background of the emergence of computer networks? We have eliminated the phenomenon of information silos now, but several years ago, did you know that computer networks could help … Read more
The Concept of OSI: Open System Interconnect is a reference model defined by ISO (International Organization for Standardization). It is a flexible, robust, and interoperable model, not a protocol, commonly used to analyze and design network architecture. The OSI model is divided into seven layers: OSI divides the network into seven layers, from bottom to … Read more
Introduction: In actual work environments, PLCs may communicate and exchange data. Typically, communication requires devices to be on the same network segment. However, what if our devices are not on the same segment? This article introduces how two PLCs can perform TCP/IP communication to exchange data when they are not on the same network segment. … Read more
As we all know, the TCP/IP model is the foundational model for most network communications today, and its basic function is to define the technical framework for interconnecting devices. Through it, networks around the world can interconnect, and information can be exchanged globally. The protocol stack is also known as the communication stack. When we … Read more
Recently, Mu Chengjin wrote that “the recently released Treck company’s TCP/IP protocol stack vulnerability proves that the Internet’s TCP/IP protocol is the fundamental cause of Internet security threats.” Mu Chengjin’s target this time is the core protocol of the Internet architecture, “TCP/IP,” but clearly this claim that “TCP/IP is the root cause of Internet security … Read more
