Computer (Computer) full name: Electronic computer, commonly known as computer, is a modern intelligent electronic device that can run according to the program and automatically and high-speed process massive data. Composed of hardware and software, a computer without any software installed is called bare metal. Common forms include desktop computers, notebook computers, and mainframe computers, and more advanced computers include biological computers, photonic computers, and quantum computers. the

With the rapid development of computer technology, more and more peripheral devices are connected to the computer. line, camera USB connection line, and some are connected to scanners, USB storage devices, card readers, switches/routers and other network equipment. . the

Most computer cases now have a front USB port or an audio port, and the use of a USB hub can alleviate the shortage of computer external interfaces, but it cannot fundamentally solve the situation of "many" and "chaotic" computer connection lines. Since there is no dedicated computer connection line arrangement equipment or connection equipment, it is necessary to lay and organize a large number of connection lines no matter in the process of installation, commissioning and maintenance after use, which not only increases the extra workload, but also increases the cost of the computer. The failure rate in the use process is more serious, and there are potential safety hazards. Since most of the interfaces of the computer are set on the back panel of the computer, which is far away from the use position of the desk, it is not very convenient to connect most of the peripheral devices, and some peripheral devices need to be connected to the computer with extension cables. The rear panel not only increases the connection line, but also makes the connection more confusing. the
