    How to Make a Network Cable

    Network cable is an essential product when we are intended to decorated our new home or arrange the cabling in various circumstances.Comparing to home cabling which only demanded a short distance network cable that most of us are more inclined to buy a ready-made network cable with RJ45 plug, other occasions such as engineer cabling or office cable require a network cable that exceed the normal distance patch cable in the market. When you are placed under this situation, it will be really helpful if you can handle the RJ45 plug installation by yourself. Before the installation, you are advised to purchase a network cable crimping tool. Most of the crimping tool on the market are now 3-in-1 function, which means that it can realized all the three function: stripping, cutting and crimping in one tool. In short, we can divide the installation process into five steps. First of all, it’s about stripping the jacket(insulation layer) of the patch cable. In order to avoid any damage to the internal wire, the operator are suggested to use the crimping tool to cut a light circle first, then slightly rotate the crimping tool to peel off the jacket from the cable and expose the internal wire core. Step two is about arrange the correct sequence of the internal wire which we could inspect 8 different type of metal cables after the stripping. They are made in different colors and color combinations for distinctive recognition: orange, orange+white, green, green+white, blue, blue+white, brown and …

    How Long Can an HDMI Cable Be

    HDMI is the abbreviation for High Definition Multimedia Interface, a digital video/audio interface technology. HDMI cable is the abbreviation for the connection cable between multiple high definition multimedia, which can transmit uncompressed high definition video and multi-channel audio data in high quality. HDMI cable mainly transmits digital signals, the quality of HDMI cables on the market varies, many HDMI cables in the transmission distance of more than 10 meters after the degree of attenuation is more serious, and in the choice of HDMI cable must buy a suitable length for their own, not too long, otherwise it is not conducive to transmission. Attenuation is the HDMI cable receiving device in how many meters can maintain the signal transmission. In fact, attenuation in the case of higher frequencies, the signal will be more attenuated. When using HDMI cables, the main thing to look at is the quality. If the quality is good, pure copper HDMI cables can generally transmit up to 60 meters. Generally speaking, for best results, the recommended HDMI connection length is usually within 15feet (about 4.6m), and certain better quality HDMI cables can do up to 30feet (about 9m). If the quality control of the cable itself is done well (although not necessarily expensive), there are HDMI cables that can achieve 50feet (about 15m) can also work properly. But when it is this long, the situation will become more delicate, you will probably see the display device side of the “flicker” phenomenon. You may also experience a more …

    Will cloud computing be the future trend?

    What is a cloud computer? it’s about sharing resources, software and information over a network. In this case, via “the Internet” or, more correctly, an Internet connection. Information and data are stored on physical or virtual servers that are maintained and controlled by cloud computing providers. As a personal or corporate cloud computer user, you can access information stored on the “cloud” through an Internet connection How does the cloud computer works? To understand how a cloud system works, it’s easier to divide it into two parts: the front end and the back end. They are connected to each other through a network (usually the Internet). The front end is the user or client side of the computer. The back end is the “cloud” part of the system. The front end consists of the client’s computer or computer network. It is also the application that is essential to access the cloud computer system. Not all cloud computing systems have the same user interface. On the back end of the cloud technology system, there are the various computers, servers, and data storage systems that make up the cloud. A cloud computer system may include any computer program from data processing to video games. Typically, each application has its own dedicated server. How does cloud storage work? Connected through an Internet service, cloud storage works by enabling users to access and download data to any selected device (such as a laptop, tablet or smart phone).

    What is the relationship between FPS, V-Sync and Motion Blur

    FPS is the definition in the image field of the number of frames per second transmitted on a screen. FPS is a measure of the amount of information used to save and display dynamic video. The more frames per second, the smoother the action displayed will be. A movie plays at 24 frames per second, which means that 24 frames are projected on the screen in one second. If you pause the movie, you will find that most of the frames are blurred, because each frame in the movie is a picture formed by the camera shutter exposure for 1/24th of a second. That is, all the information in this 1/24th of a second, are recorded on this frame. But the principle of the game is different. The game screen is rendered in real time by the engine, and each resulting frame is a still picture of a certain moment, but the information about the displacement between the two frames does not appear on your screen. To compensate for this shortcoming, many game manufacturers also provide a “motion blur” feature in the settings: that is, they add a blurring effect to each frame to simulate a dynamic look and feel like a movie. When the game frame rate is low, turn on the “motion blur” to reduce the feeling of lag to a certain extent. But even so, the game is still difficult to achieve the smoothness of the movie considering the game is not only to watch, but more …

  • What is Resolution

    Resolution is basic element to intuitively evaluate the quality of video and the performance of the display devices. This parameter general represents the definition of the picture and how many details one devices could provide to viewers. Resolution is a parameter which defines the precision of the video. As we all know that the whole image that has been provided by the display devices are combined with enormous tiny pixels that the more pixels one screen could contain, the more details it could provide to the viewer. There are several types of the standard resolution that has been adopted in most of our display devices in the modern era. Except from several low definition such as 480P or 360P, the resolution that is higher than 720P could be generally concluded as the high-definition(HD) picture. 720P which has a horizontal pixel of 1280 and a vertical pixel of 720 is able to deliver a total number of 921 thousand pixels. Considering it is an boundary between the definition of HD and ordinary picture in modern standard, it could provide the viewer with the picture that contains most of the information comparing to the reality, for example, the loge of passersby’ coat or the clear license plate of the car. The next higher standard about the resolution is 1080P which enjoys a pixel of 1920*1080 and a total number of pixels of 2073600. Theoretically, it contains a double number of pixels within the picture, so it is qualified to provides double details …

    What is the difference between HDMI to VGA and VGA to HDMI? Can they be used interchangeably?

    We will further discuss the relationship between HDMI and VGA. When connecting a signal source to a display device, if the interface is the same, you can directly purchase a cable to connect, but what if the interface is different? For example, what if the source is HDMI and the monitor is a VGA connector? This is the time to use a converter. 1、HDMI to VGA HDMI to VGA cable comes with a power supply interface, compared to the converter, the conversion cable can be directly connected without additional conversion, one cable easily converted to HD large screen, simple and convenient, suitable for Xiaomi boxes, laptops, set-top boxes, PS3 and other HDMI interface devices, connected to VGA interface devices such as TVs, monitors, projectors and other devices to convert HD large screen picture. HDMI to VGA converter is a digital signal to analog signal conversion, the signal source is the HDMI interface, the display device is the VGA interface which means that you need to prepare a VGA cable to connect. But because the VGA does not support audio transmission, you won’t have any sound in your terminal devices even though you got a HDMI interface. You need to connect another audio device or directly buy a converter with audio and video synchronization conversion. As for the resolution, HDMI to VGA converter support 1920*1080P resolution and 60Hz refresh rate. 2、VGA to HDMI VGA to HDMI is a conversion from analog signal to digital signal, which requires that the signal source …

    What is the merits and drawbacks between analog signal and digital signal?

    We’ve all known that VGA interface adopted the analog signal whereas HMDI interface uses digital signal for transmission. So what are the relative advantages and disadvantages between these two types of signals? 1. Analog Signals The advantages of analog signals are intuitive and easy to implement, but there are two main disadvantages.First of all, it has a poor confidentiality considering analog signals, especially microwave and wired open-line communications, can be easily eavesdropped. As soon as an analog signal is received, it is easy to obtain the content of the communication. The next deficiency about analog signal is its weakness in anti-interference. During the transmission of the electrical signal, it is subjected to external and internal noise interference within the communication system, which makes it difficult to separate the noise from the signal, thus degrading the communication quality. The longer the line, the more noise accumulates. 2. Digital Signals Advantages of digital transmission First of all, digital signal has a better confidentiality than analog signal. And digital signal improves anti-interference capability that can be mixed with noise during transmission, and the input signal voltage can be measured using the threshold voltage (called the threshold value) constituted by the electronic circuit. At last, an integrated digital communication network can be constructed. With time-division switching, transmission and switching are unified to form an integrated digital communication network. Disadvantages of digital signals Occupies a wider frequency band. Because the line is transmitting a pulse signal, the transmission of digital voice information all the way …

    What is USB Type-C

    The famous Type-C interface. It was first introduced in August 2014, using the USB 3.1 transfer standard. The application of this standard meant that a transfer rate of 10Gbps (about 1.2GB/s) could be achieved by using this small connector with the width less than 1cm . Furthermore, USB-Type C overcomes a problem that has been accompanied with data interfaces since its dawn time. That is, at last, the Type-C port no longer possess the front and the reverse which means that it supports the random plugging. In addition, the compatibility of the Type-C interface is not to be underestimated. In addition to the traditional connection to cell phones, Type-C also supports computers, game consoles and other mass storage devices and docking stations. This is mainly due to the strong support for Type-C from the world’s leading electronics companies, including Apple.
