Terminals are typically \"dumb\" user devices that are connected to a centralized mainframe system, such as an IBM mainframe computer. The terminal receives keyboard input from the user and sends it to the host system. The host system processes the keyboard input and commands of this user, and then the output is returned and displayed on the screen of this terminal. Personal computers can run programs called terminal emulators to mimic the work of a dumb terminal. At present, common client devices are divided into two categories: one is fat client and the other is thin client. Then, the PC as the representative based on the open industry standard architecture, more powerful equipment called \"fat client\
1. From the technical level, the data processing mode will be from decentralized to centralized, the user interface will be more humane, manageability and security will be greatly improved; At the same time, communication and information processing will be fully networked, and unprecedented system expansion capabilities and cross-platform capabilities can be achieved.
2. From the application form, the network terminal device will not be limited to the traditional desktop application environment, with the diversification of connection methods, it can be used as a desktop device, but also can be used in the mobile and portable way, the terminal device will have diversified product forms. In addition, with the expansion of cross-platform capabilities, in order to meet the needs of different system applications, network terminal devices will also appear in many faces: Unix terminal, Windows terminal, Linux terminal, Web terminal, Java terminal and so on.
3. From the application field, the situation that the terminal equipment in the era of dumb character terminal and graphic terminal can only be used in the window service industry and counter business will never return, and the non-counter business such as online banking, online securities and bank low counter business will be widely used. At the same time, the application field of network terminal equipment will rapidly expand to emerging non-financial industries such as telecommunications, electricity, taxation, education and government. The terminal in marketing refers to the terminal store in direct contact with consumers, which is an organic part of the channel. Only through the terminal can the manufacturer realize the value of the product. In modern marketing, terminal more and more prominent its important position, control terminal can be said to control the market, Gome, Suning's success is thanks to the control of the terminal.
