, which reduces the load on the telephone switch. They do not need to be dialed and are always online. This means that xDSL does not have to be used to access the Internet. The "x" in xDSL represents various digital user loop technologies, including HDSL, SDSL, ADSL, RADSL, and VDSL. The following describes the DSL technologies. 1. HDSL high-speed digital user line) HDSL is a symmetric DSL technology with the same uplink and downlink speeds. HDSL use

of broadband services. The network structure is commonly seen in point-to-point, link-type, or ring-type network structures. The transmission rate ranges from 34Mbps-155Mbps. The transmission distance can be from several thousand meters to hundreds of kilometers. The DLC technology can be used to implement fiber-to-road (FTTC) and fiber-to-household (FTTH) phases. The system has mature technologies, high reliability, and is easy to popularize and apply. Many domestic manufacturers have launched

the same time. Serial Port Many new computers have two 9-pin COM ports; this is the DB-9 positive connector. Vintage computer has a DB-9 positive connector and a DB-25 positive connector. The 25 positive connector is similar to the 9 pin, but it is relatively large. Let's see what the serial port is like: DB-9 and DB-25 use different pin distributions, so let's look at it later. Let's take a quick look at the COM port of the new computer: Note that both COM ports have DB-9 connectors, but no

, dispersion and non-linearity are the main considerations. In order to reduce the dispersion and nonlinear limitations on the system performance, non-zero dispersion displacement optical fiber (NZ-DSF) has been launched, such as Corning LEAF (Large Effective Area non-zero dispersion displacement optical fiber ). These new optical fibers and dispersion management technologies have been effectively applied to commercial single-mode optical fiber systems. With the development of laser transmitters

What are the 10 times faster than 4G in addition to 5G ?, 5g4g I believe that if you are interested in electronic products and technologies, you must be familiar with the word "5G". This popular communication technology that has been used since last year will always come to our sights from time to time. In addition, at the just-concluded CES, Qualcomm also depicts a future that is at your fingertips and full of technological sense around 5g. Now let's imagine that 5G may be the same as 4G in th

The next evolution of the Wi-Fi standard, 802.11ac, will provide faster wireless connection speeds and higher data transmission rates, which will play a role in promoting network video browsing and uploading and downloading large-capacity files. Although wireless technology is booming, it cannot completely replace wired Ethernet. Analysts pointed out that the cost of Wired connection is relatively low and will still be favored by the market. Market re

With the continuous development of routing technology and the upgrade of technology, the application of multi-Wan Port Routers has also been greatly promoted. Here we mainly analyze the performance and characteristics of a Multi-Wan port router product of xiaonuo. With the increasing number of Internet applications and the popularization of real-time communication, video, and file downloads, most users and network administrators obviously feel that the network speed is getting slower and slower,

speeds. This is why we recommend that you choose a set of products when purchasing wireless devices, after all, the set products are compatible with each other in terms of connection speed and working mode. TIPS: Of course, the transmission speed of many brands of wireless network cards can be adjusted by themselves, that is to say, not only the 11 m and 54M modes work, he will automatically adjust and select a suitable speed for transmission based o

by the CD was for win98, but the XP driver in another directory on the CD was not automatically scanned. Therefore, the problem was solved after the driver was manually installed. Therefore, whether the driver is correct or not and whether the driver is an official version is the main factor that determines the stability of the wireless network. The second is the connection speed of the wireless network adapter. It is well known that in a wired network, when two computers transmit data, if the

With Webtoolhub, you can know the page size and loading time of CSS, Javascript, and images on webpages at different connection speeds, these are all required for basic web page speed testing. IWebTool You can compare 10 pages at

In web design, Parallax Scrolling is a popular Web design technology, 3D motion is very interesting by moving multi-layer backgrounds at different speeds or in different directions. The following are some examples of excellent web pages that use the parallax scrolling effect: Parallax refers to the Visual Difference formed when an object is viewed from different points,This term is derived from the Greek family of π α P? λ α (Parallaxis), Which means

, respectively, 0 and 1. The secret of the easing function is completely unlocked. p, firstNum, and diff are percentages rather than actual values. The return value of the easing function is the progress of the displacement. The diff value is 1, which means the animation is run at a speed of 1 times. After calculating the displacement progress, you can use "Initial Value + (final value-Initial Value) × progress" to calculate the current displacement value: This. now = this. start + (this. end-th

This is a very cool jQuery and CSS3 imitation AppleTV poster background visual effect. When the Visual Difference effect moves the mouse around the screen, the various elements in the poster move at different speeds to form the Visual Difference effect, and also has some special effects of streamer.

hardware problem. I have this kind of personal experience. After determining whether the hardware is faulty, I should first change the memory or not. At this time, I found that the power supply fan sounds great, isn't the power supply cooling poor? I then switched to a PX power supply for the technology exhibition. I see the dual-Fan Design of this type of power supply, that is, an 8-centimeter fan is installed in the air inlet, which speeds up the a
