Server Nouns Interpretation [Host / Terminal Structure] The earliest computer network is accompanied by the appearance of the two concepts of the host (Host) and Terminal. The host at the time usually refers to a small machine or a strong function, and the terminal refers to a computer external device. Now the terminal concept has been positioned to a device integrating by a CRT display, a controller, and a keyboard. The fundamental difference between the microcomputer we usually refers to, there is no own central processing unit (CPU), of course, has no own memory, the main function is to send the request data entered by the keyboard to the host (or printer) and convert the host. The result is displayed. With the development of the Internet, there is currently a new meaning in the term "terminal". For the Internet, the terminal generally refers to the computing device that can access the network, such as personal computers, network TV, can access mobile phones, PDA, etc. [Client / Server Structure] This is a form of network software operation. Typically, a system with a client / server structure has a server and a large number of clients. The server is equipped with a large-capacity memory and installs the database system for data storage and data retrieval; client installation dedicated software, responsible for data input, operation, and output. Clients and servers are independent computers. When a computer-connected computer provides a variety of network services (such as data, file sharing, etc.), it is called the server. And those computers used to access server data are called clients. Strictly speaking, the client / server model is not defined from the perspective of physical distribution, which is reflected in the implementation of network data access. Systems with this structure are currently available in a wide range of applications. Such as hotels, hotel room registration, settlement system, POS system, bank, and postal telecommunications network system, etc. [Browser / Server Structure] This structure has prevailed in the late 1990s, and is the current most popular network software system structure. It is gradually replacing the client / server structure, making it the first choice for network software developers. As the Internet browser features become more powerful, in many cases, the browser can replace client software for the client / server structure. That is, the developer can follow a certain rule to develop a set of network software running on the server, and the client can directly use the browser to input and output, without having to develop specific software for the client. Currently, the browser / server structure and client / server structure have become the main form of computer applications, and the server play an indispensable important role, so the server is also called the "E-age basic element". [IA Architecture Server] The server usually referred to as an IA (Intel Architec-Ture) architecture server, since the architecture server adopts an open system, and realizes industrial standardization technology and a large number of hardware and software at home and abroad. Support, on the basis of mass production, especially in my country, in China, especially in our country. In 2000, the top three of the domestic IA architecture server suppliers were HP, IBM, and wave. [IA64 Architecture Server] IA64 Processor I-TANIUM (Anteng) is another milestone in the high-performance computer field since Intel Self-launch 32-bit microprocessor. The server based on the IA64 processor architecture has 64-bit computing power, 64-bit addressing space, and 64-bit data paths, which breaks through many of the traditional IA32 architecture, the processing power of the data, the stability, security, availability, and considerable Rationality has been improved. my country is currently only launched in a wave of launching the architecture server.
