5 Internet Connection Methods

This article describes five Internet connection methods. Generally, we open a computer every day. If we want to use a web page to search for, we are still used to using the Internet, at least on engines like 360. Therefore, our understanding of the Internet is very important. Before connecting to the Internet, it is very important to understand the connection method, which not only deepens the user's understanding of the network, but also helps the computer desktop wallpaper to select a suitable way to access the Internet. 1. dial-up Internet access is the most widely used Internet access method in the past. It connects computers to the Internet through a modem and telephone line and further accesses network resources. The advantage of dial-up Internet access is that the installation and configuration are simple and the one-time investment is low. You only need to obtain an Internet account from the ISP (network operator) and connect the necessary hardware settings; the disadvantage is that the speed is slow and the access quality is poor, and users cannot receive calls while surfing the Internet. This method is suitable for individual users who spend less time accessing the Internet. 2. ISDN is short for the Integrated Service Digital Network, that is, the narrowband Integrated Service Digital Network, commonly known as "one-line communication". It also uses existing telephone lines to access Intemet. This internet access method has the following features: Multi-Service: multiple services such as telephone, fax, visual text, and videophone can be implemented. Digitalization: Provides end-to-end digital connections, and completely digitizes terminals to terminals, resulting in high information exchange quality. Ease of use: you only need one inbound interface and a uniform number. On this interface, you can connect to multiple terminals of different types. The disadvantage of using ISDN to access the Internet is the high cost because using ISDN requires dedicated terminal settings (including network terminal NT1 and ISDN adapter ). 3. broadband Internet access is called asypolicric DigitalSubscriber Line (Asymmetric Digital user Line. ADSL is a high-speed data transmission technology on a common telephone line. It uses a frequency that has never been used in a telephone line, so it can break through the 56 Kbps speed limit of the modem. The main feature of ADSL technology is that it can make full use of the existing telephone network and install ADSL devices at both ends of the line to provide users with high-speed broadband services. In addition, ADSL can coexist with a common phone on a telephone line, while receiving and dialing a common phone at the same time, without affecting each other. The advantage of ADSL Broadband Internet access is the star structure, good confidentiality of 2013 popular themes, high security factor, fast speed and low price. The disadvantage is that analog signals cannot be transmitted. 4. Optical Fiber Internet access refers to the use of optical fiber cables to replace copper-core telephone lines and access Intemet through optical fiber transceiver, routers and switches. This Internet access method allows the download speed to reach 6 Mbps and the upload speed to reach 640 kbpS. The advantages of fiber-optic Internet access include exclusive bandwidth, stable performance, low upgrade cost, no electromagnetic interference, low loss, strong security and confidentiality, and long transmission distance. 5. Wireless Internet access means that you do not need to connect to Intemet through telephone lines or network lines, but through communication signals. As long as the user's location is within the radio wave coverage of the Wireless Access Port, and then with a compatible wireless network card, you can easily access the internet. The advantage of wireless Internet access is that it is not restricted by the location and time, software articles are fast, and you can also send and receive text messages using the wireless network card. The disadvantage is that the cost is high.
