Writing multi-process/Multi-thread program has become an important feature of modern programming, and

In a distributed service framework, one of the most fundamental issues is how remote services communicate, and there are many technologies in the Java domain that enable remote communication, such as RMI, MINA, ESB, Burlap, Hessian, SOAP, EJB, and JMS, What is the relationship between these nouns, and what is the rationale behind them, to understand these are the fundamentals of implementing a distributed service framework, and if there is a high leve

I. Opening Program The main purpose of inter-communication is to achieve data sharing and information exchange between applications on multiple computers (or the same server. In different computer systems, data sharing and information exchange can only be achieved through protocols between networks. In the same computer system, data sharing and information exchange can be achieved through only a certain channel between them. There are many similarit

Inter-process Communication overview Process communication purposes Transferring DataA process needs to send its data to another process. The amount of data sent is between one byte and a few m bytes Sharing DataMultiple processes want to manipulate shared data, a process to share data Notice thingsA process needs to send a message to another process or group of processes. Notifies it (they

Inter-process communication is the transmission or exchange of information between different processes, so what is there between the different processes that can be accessed by both parties? The user space of the process is independent of each other and is generally inaccessible to each other, with the only exception being the shared memory area. However, the system space is a "public place", so the kernel can obviously provide such conditions. In add

Definition of energy efficiency in communication networks and its value for energy-saving management across the network Improving the energy efficiency of communication networks (EE) is an important means to improve the profitability of operators. The energy efficiency indicators are further divided into TEE and IEE) it can better adapt to the organization model of Maintenance Management for telecom operat

Purpose of inter-process communication Data exchange State synchronization Event notification Resource sharing Process Control In general, the communication between processes can be divided into two types, one is Transmission control information, the other is the transmission of large amounts of data. General control information is only one or a few bytes, to achieve high-speed

Project Teams in the software industry rely on communication. In the project, there is no difference in how to emphasize communication. In fact, we can find the root cause of most problems in communication. For example, many of us have a feeling at work that there are always gray areas in our work, these fuzzy points lead to discord in our work. It can be clearly

In order to achieve effective communication, in addition to the good communication skills of the parties, the correct choice of communication methods is also very important. This series is divided into four parts, the importance, methods and methods of communication in project management are discussed.

A large application system often requires many processes to collaborate, and the importance of interprocess communication is obvious. First, interprocess communication can be implemented at least by transferring open files, and different processes pass information through one or more files, in fact, this approach is used in many application systems. But in general, interprocess

Accidental opportunity, re-write a comparison of Windows socket communication based on the code, too long no contact socket and multithreading, many blog, but found that most of the content is older, so decided to write a blog, by the way to sum up their own. Content IntroductionIntroduction to basic functions of network communication C++11 multithread Introduction Socket

In the past, communication will always become the most important and possibly the most influential issue in the work, improving personal business capabilities, adjusting work attitude is much less difficult than improving effective communication. There are two types of communication: communication between people and

A Method for querying serial communication by calling Win95 API Abstract: In Win95, the serial communication mechanism has been improved and standardized compared with Windows 3.x. This article describes how to use a simple serial port query method to implement serial communication from the perspective of calling an API.Key words API, serial

Java was originally introduced as a network programming language, which provides a high degree of support to the network, which makes the communication between client and server become reality, and in network programming, the socket is the most used. Like everyone familiar with the QQ, MSN has used the socket-related technology. Now let's uncover the mystery of the socket.Socket ProgrammingBasic knowledge of network (refer to computer network)about th

This blog is mainly about indirect communication technology, including group communication, publish-subscribe system, Message queue, distributed shared memory, etc. Indirect communication Indirect communication is defined as an entity communicating through intermediaries in a distributed system without direct couplin

When it comes to Linux operating systems, you cannot fail to mention network technology. The Linux system itself is a network of products, it can be on the network for people to download freely, and be modified and perfected. The Linux system supports a variety of network protocols, and its shell provides powerful networking commands. These advantages enable Linux to provide a complete solution for many small and medium sized network applications. Referring to the computer network, we have to f
