The development of switch technology is very rapid. From the third-layer switch technology to the fourth-layer switch technology, the experience is very short, meeting more needs of users. When I first heard the word "Layer 3", I had some puzzles. The subsequent concepts of Layer 4 switching and Layer 7 switching are even more confusing. In fact, in strict terms,

in the IT industry for more than 5 years, I have often seen many people hold the view that "technology is not important, the key is business." "There was a time when I thought so, too.　　So, that's the right idea. 　　1. The source of the idea so, let's start from scratch and see how this idea is produced. 　　Domestic traditional IT companies, basically rely on "do Project" live, and the most important thing is to take a single, only to get a list to earn

This series of articles will give a comprehensive introduction to parallel programming technology (also called multi-core programming technology) and applications in. net4. The topics in this article are as follows: 1. Differences between parallel programming and multi-threaded programming. 2. Advantages and Disadvantages of Parallel Programming Technology 3. Whe

Overview of technical development requirements for access networks With the advancement of society and technology, the general trend of information technology development is the integration of three technologies, telephone, computer, and television, industry, and even network ". It is manifested in the Cross-penetration of the business layer, the application layer uses a unified communication protocol, the

View Microsoft technology from ThoughtWorks 2017 technology radar, thoughtworks2017ThoughtWorks produces two technical radars each year. This is a report on technical trends. It is more specific than other technical quotations and forecast reports we can see on the market, it is more operable because it involves not only new technology trends, such as cloud platf

Onlookers: layer-2 exchange technology, PK layer-3 exchange technology. A traditional LAN switch is a L2 network device that constantly collects information during operations to create a MAC address table. Layer-3 switching is also called multi-layer switching technology or IP address switching technology. In today's

In the field of data exchange, how to effectively solve security and efficiency issues has become the main proposition. The rapidly growing number of users, endless new businesses, and countless viruses have become three major challenges for network applications. SPOH technology emerged in this context. What is SPOH technology?　 SPOH technology synchronization p

Although we have been working on technology for many years, we are still on the technology path, whether we are hesitant or uncertain. No matter what kind of position we are in or what kind of salary we are holding, we will ask ourselves whether we can achieve that level by doing technology. Simply put, in fact, many of us are still confused about the

In the operating system, there is the concept of multi-threading (multi-threading), which is well understood, because a thread is the smallest scheduling unit of a process, and a process contains at least one thread. This article describes the CPU-specific hyper-Threading technology. In short, multithreading is softer, hyper-threading is hard, and both are inherently virtualized .1. What is Hyper-threading (hyper-threading)?Hyper-Threading (hyper-thre

Although 3G is an integral part of NGN, its development is also more or less affected by the Softswitch technology. From this, we can see that the Softswitch technology has become the focus of public attention in recent years, it will become the core technology of the Next Generation Network. The information industry has made great efforts to propose the Softswit

beginsa stay in the testing industry is n years, experienced a lot of people a lot of things, learned a lot of things, today to have the opportunity to talk with you about technology, development, life, although more vulgar but is some sincere words. This time we are talking about is the younger brother's own idea, perhaps there is not in line with the public appetite, do not have to pinch the rack, heavy exchange learning, heavens. 1Test TechnologyS

Before and after the Spring Festival, the blockchain again blew our circle of friends: Three o'clock the continued force of the group, Venezuela's oil currency issued, "in the Cong" suddenly appeared, the price of the encryption currency fluctuations ... Now the streets are talking about blockchain, and our blockchain technology salon has been in this atmosphere for the fourth period. In view of the blockchain, we discussed its historical developmen

Binary Tree roaming-Summary of programming technology and skills (I): recursive technology this series is divided into three articles to summarize common techniques and skills in binary tree programming. The first article is about the recursion Technology of Binary Tree programming. The second article discusses how to convert recursive Programs into non-recursive

Frequency-hopping spread spectrum; FHSS receives signals transmitted by narrow-frequency carriers of a specific type at both ends of synchronization and at the same time, for a non-specific receiver, the hop signal generated by FHSS is also called pulse noise. FHSS signals can be specially designed to avoid noise or non-repetitive channels of one-to-one channels, and these frequency hopping signals must comply with fcc requirements, the maximum interval between 75 or more frequency hopping signa
