I usually find some good materials at work, but you cannot use them directly due to copyright issues. What should we do? I will study its structure, as shown in the figure below, I thought about the castle I was thinking about, so I planned to work
Because I recently studied Asp.net, and I also watched Javascript. I encountered some problems and doubts during the learning process. I recorded some ideas and test results. If any, please correct me. Thank you!
I read a book while learning
How does PHP stitch binary data into strings?
For example, the character "You" of the UTF8 code is "e4bda0".
Now there is an array of $arr
$arr = Array (chr (228), Chr (189), Chr (160));
How do you stitch it up into a piece that allows it to

Usage Environment:Talent Network Project has a resume confidential settings, which has a filter keyword, only a company name contains one of the key words, it does not show the resume, of course, I have not done there, and now is to do the keyword
I. Why is the application bandwidth provided by Category 6 products required?
A: The bandwidth is equivalent to that of a highway. You must provide enough bandwidth to increase the data speed. Increasing the bandwidth by twice is equivalent to doubling the public speed, the development of data speed in the past and future demand forecast show that the data speed will double every 18 months. Today, applications running at 1 Gbit/S speed have pushed cat5e
This article mainly explains how to correctly select the network cabling system and precautions in the campus network system. When using the campus network system, many people may understand the network cabling system, it doesn't matter. After reading this article, you will certainly have a lot of GAINS and hope to help you solve the problem.
1. FF Optical Fiber Connector product materials (indoor twisted pair wires)
According to authoritative statistics, more than 70% of network faults are caus
The test of the Integrated Wiring System is still quite common, So I studied the differences between the test of the six types of Integrated Wiring System and the cat5e. I would like to share with you here, hoping to help you. Facts have proved that wireless technology is not an alternative to cat5e. It is applicable to environments where mobility is critical, or where Cables cannot be laid between switches
high-quality photo materials.
Cat5e unshielded twisted pair wiresThe cat5e unshielded twisted pair cable is a cable that improves the performance of the cat5e unshielded twisted pair cable. Many performance parameters, such as near-end crosstalk, attenuation crosstalk ratio, and ripple loss, have been improved, however, the transmission bandwidth is still 100 MH
How to differentiate between dual-screen and unshielded Network cables and dual-screen network cable shielding
As a part of the Integrated Wiring Design and Construction, the network cable is the basic medium for most information transmission systems. Its importance is self-evident. What is the main role of this article in resolving and shielding the network cable? What is twisted pair wires? What are STP, SFTP, UTP, FTP, and ASTP? What's the cat5e d
equipment are connected.
3. Other data points and voice points are reserved for connecting to the production workshop.
There are 22 information points in the entire building, including 16 data points and 6 voice points. All information points are designed in accordance with the cat5e standard to achieve a data transmission speed of MB and all information points can be used for voice and data usage through line adjustment. The distribution frame is se
quality of production varies greatly from manufacturer to manufacturer, especially in the domestic price-oriented environment, in order to reduce costs, many manufacturers use copper clad iron and copper clad steel instead, resulting in a decline in the network cable transmission distance, and even the network instability, packet loss, and other phenomena, and equipment manufacturers often back to the black pot, it's really embarrassing.
Therefore, if you want to make PoE play the best effect,

The main network cable uses the AVAYA cat5e unshielded twisted pair wires, and the position of the switch in the working subsystem uses the AVAYA cat5e information module and cat5e jumper. The vswitch is connected to the client only

With the release and Implementation of the Fast Ethernet standard, cat5e twisted pair wires have been widely used in network cabling. However, due to the misleading publicity by some vendors and network companies, and the lack of necessary knowledge about related standards by some network users, it is hard to identify the true and false of the cat5e twisted pair. However, the selection of non-compliant

I. First, let's take a look at what is twisted pair wires.1. Twisted Pair wires: as a transmission medium, it is made up of two thin copper wires with insulation material.

The acceptance of the Integrated Wiring System is a special concern for the design and construction personnel. Many people may not understand the acceptance of the Integrated Wiring System. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things.
When the first installation of cat6 copper cable systems by an engineering engineer who often thinks that he has several years of construction experience, he will be surprise
At present, most commonly used Ethernet Media are cables, supplemented by optical cables. Generally, 10 BASE-T Ethernet requires only three types of links. 100Base-T Ethernet requires five types of links to ensure its operation. In addition, a considerable number of five types of links can support BASE-TX applications, the cat5e chain can stably support 1000Base-Tx links. During the upgrade process from many users to 100Base-T and from a few users to
point should be a m exchange type or even a fiber optic information point.
Terminal devices in the work zone, such as telephones and fax machines, can be directly connected to each information outlet in the work zone by Corning FutureCom cat5e or cat5e twisted pair wires, or use adapters such as ISDN Terminal devices), balanced/non-balanced converter to convert and connect to the information outlet.

horizontal link is still relatively low. Once our network is upgraded to a higher speed, unpredictable results will easily occur, affecting our normal use. The correct and safe method is to pre-embed two 86-side boxes and install two dual-port 86 panels at the location where four information points are required.
SIMON electric Integrated Wiring System provides two kinds of double port 86 panel for users to choose from: Flat port and oblique port. Our panel features fire prevention, high strengt
