I. Introduction
Before starting this chapter, I would like to raise a question: "If the absolute value of an integer is equal to itself, What is the number ?" If your answer is 0 and all positive numbers, please read this article with patience.
This chapter is the second part of my "code Mystery" series. The previous article "code mystery-opening/preface" briefly introduces the differences between computers and mathematics.
There are many complicated and profound contradictions in mathematics. T

The above coordinates point to the Silicon Valley, recently began to study the Internet distributed architecture, the cusp, on the tall, the special and the Geek friends share, mutual encouragement.
Internet Architecture
In recent years, the rapid development of the Internet, the big data era, booming years, we as a technical geek, need to keep pace, trends.
Use ASP, VB and XML to build Internet applications (1)
The era of using stand-alone applications on PCs is about to pass, and most applications now develop web versions or most need to share rich data resources on the Web. Although we have written for a long time based on client/server applications, most of these programs only run in small LANs. However, there are many objective reasons that require us to m
the normal operation of Internet cafes and have destructive power on the billing system. In general, the technical vulnerabilities of Internet cafes mainly fall into the following categories:
1. Internet browser-based technical vulnerabilities: As we all know, in Windows, Internet
Internet cafes are large public Internet sites with a large number of Internet users, which brings a great burden to the network, you must select the corresponding network device according to the actual situation. From the perspective of Internet access, there are no doubt two network cable and wireless networking solu

The rules that everyone follows are called protocols ).

Next we will introduce the functions of each layer, mainly about the main protocols of each layer.2. We start from the bottom layer. What is the first thing to do when computers need netwo
(changing all 0 bits to 1 and vice versa) and bitwise OR operations with the address (or equivalent network/subnet prefix) of any computer in the subnet.Historically, the use of broadcast addresses as destination datagrams is also known as directed broadcasts . At least theoretically, this broadcast can be routed over the internet as a single datagram until it reaches the destination subnet, and is sent to
The services currently provided by Internet cafes, such as web browsing, online games, online movies, distance education, and other basic services, are all related to the Internet, the quality of the network directly determines the viability of Internet cafes. Therefore, how to plan a high-quality network environment is a key point that
modelThe realization of the Internet is divided into several layers. Each layer has its own function, just like a building, each layer is supported by the next Layer.The user touches, just the top layer, does not feel at all below the Layer. To understand the internet, you have to start from the bottom and understand the capabilities of each layer from BELOW.There are different models for layering, some mo
mind, the convenience of network access everywhere seems to be more suitable for the home, rather than the commercial location of Internet cafes. It is the manager who runs Internet cafes on the first line, and it is difficult to understand what the Internet cafes need for wireless networks.

provide two access modes: ADSL and optical fiber, this is also the access method currently used by most Internet cafes. However, according to the actual situation, different Internet cafes have selected different access combinations, including single ADSL, dual ADSL, single optical fiber, dual optical fiber, and ADSL + optical fiber.
1. ADSL Access Method

After the ADSLMODEM routing function is enabled, my home and two neighbors share the ADSLInternet connection with the SOHO switch. Now, I want to use wireless Internet access, while the other two still use wired Internet access due to distance. How can I achieve wireless connection? Please help me develop a few feasible solutions to ensure stable and secure wireless Int
routers for bars have this function. It can allocate network bandwidth. As the number of Internet cafes continues to expand, the corresponding bandwidth is also increasing. If you charge fees based on the previous single mode, for Internet cafes, funds will not be withdrawn. Therefore, we can use the traffic control function to divide the internet cafe charging
Many cainiao who are new to wireless Internet access are always worried that illegal users may share their wireless network connections without encrypting the wireless network. However, they are worried about encryption of the wireless network, affects the transmission speed of wireless Internet access. So should we encrypt the wireless network? How much will the transmission speed of the wireless network b
