ADSL
ADSL (Asymmetric Digital Subscriber Loop) technology, which is asymmetric digital user loop technology, uses an existing pair of copper wires to provide users with an up and downlink asymmetric transmission rate (bandwidth). Uplink (from the user to the network) is a low-speed transmission, which can reach 640Kbps; downlink (from the network to the user) is a high-speed transmission, which can reach 7Mbps. It was originally mainly developed for video on demand business. With the development of technology, it has gradually become a more convenient broadband access technology and is valued by the telecommunications department.
This broadband access technology has the following characteristics:
1. You can directly use existing user telephone lines without laying additional cables to save investment;
2. Strong penetration capability and fast access, suitable for centralized and scattered users;
3. Can provide users with up and downlink asymmetric transmission bandwidth;
4. Adopt a dot-point topology, and users can enjoy high bandwidth exclusively;
5. It can be widely used for accessing data such as video services and high-speed INTERNET.
At present, since ordinary INTERNET users access the network using dial-up MODEM, the sharp increase in INTERNET users may cause network congestion (this case has occurred abroad), and using ADSL can be avoided.

An IP address is a 32-bit binary number, usually written in the form of four decimal trees separated by periods, such as: 202.112.223.12, etc. IP addresses are usually divided into three categories: A, B, and C. This classification is related to the use of bytes in IP addresses. In actual applications, you can choose the type format of using IP addresses according to the specific situation. The ranges that can be represented by the three types of addresses A, B, and C are:
Class A: 0.0.0.0-127.255.255.255.255
Class B: 128.0.0.0-191.255.255.255
Class C: 192.0.0.0-223.255.255.255
IP addresses and domain addresses cannot be assigned at will, otherwise it will lead to an inestimable chaos, just like the communication addresses in our lives. When an IP address or domain address is required, the user must apply to the International Network Information Center NIC. After the application for approval, you can use the IP address wherever you can use the Internet domain address.
◎ Intranet
A network designed to process information within companies and organizations. It is an application of Internet technology within an enterprise or within a closed user group. It is unique to a company and does not necessarily have a physical connection relationship with the Internet. Its purpose includes providing services such as document distribution, software release, access to databases and training. It is named Intranet because it uses Internet-related applications such as Web pages (web pages), web browsers, FTP sites, emails, news groups and mailing lists, but its scope is limited to the company or organization.
◎ Broadband Network
It is also called wideband transmission. A local area network in which signals are transmitted in the form of radio frequency signals on different inbound and outbound channels. The nodes in the broadband network are connected by coaxial cables or fiber optic cables.

Terminal devices with WAP functions, such as WAP mobile phones, log into the Internet through the built-in micro browser of the phone, via a digital wireless network, such as a GSM network.
WAP content is written in WML, and the content displayed on the mobile phone is mainly text, without many images and colors.
The biggest advantage of WAP is mobility. With your mobile phone, you can surf the Internet at any time and anywhere, and you can read news, send and receive emails, etc.
In addition, the user's location can be known through the Internet, so the location-related information may be provided to the user, such as traffic information, nearby hospitals, hotels, bars, cinemas, cash machines and other information.
Currently, mobile phones that can access the Internet include Nokia7110, Siemens3568i, Motorola a6188 and other models.
◎ Network protocol
Network protocols are some specifications for transmitting and managing information in the network (including the Internet). Just as communication between people requires certain rules to follow, communication between computers requires common compliance with certain rules, and these rules are called network protocols.
A computer can communicate normally with other computers on the network only if it complies with the network protocol. Network protocols are usually divided into several levels, each layer completing its own separate functions. The two parties to the communication can only be connected with each other at a common level. Common protocols include: TCP/IP protocol, IPX/SPX protocol, NetBIOS protocol, etc. The TCP/IP protocol is widely used on the Internet, and IPX/SPX is used more frequently in local area networks. If a user accesses the Internet, he or she must add the TCP/IP protocol to the network protocol.
◎ Virtual host
Virtual hosts use special software and hardware technology to divide a server host running on the Internet into "virtual" hosts. Each virtual host has an independent domain name and has complete Internet server (WWW, FTP, Email, etc.). Generally speaking, if a company wants to build a website with its own independent domain name online, it must invest in a expensive server, and set up dedicated lines and maintain them with dedicated personnel. The virtual host uses the telecommunications bureau’s host to open a website for the enterprise. The website looks like the enterprise has a high-speed network exit to the outside world. This is usually the way companies build home pages.
◎ Domain name
Sites on the Internet, just like institutions or families in our lives, must have an address so that netizens can access them based on this address. The identity of its computer is a 32-bit binary code, which is the so-called IP address. For the convenience of memory, the name given to the computer on the Internet is called a domain name according to certain rules. For example, the domain name of CCTV is:/. According to the Internet organizational model, domain names are classified. There are mainly the following first-level domain names: .com (commercial organization), .net (network center), .edu (educational institution), .gov (government department), .mil (military organization), .org (international organization), etc. Most countries and regions have their own independent domain names, such as: cn (China), us (US), uk (UK), hk (*), etc. Secondary domain names such as: supercool.
◎ First-line ISDN
