Structured cabling The integrated wiring system refers to a transmission line installed in an office building or building. This transmission line can connect all the voice and digital equipment, and connect them with the telephone exchange system. The structured cabling system includes all the cables and various accessories arranged in the building, such as the switching device, the various types of client interface, and the interface with the external network, but it does not include the switching equipment. From the user's point of view, structured cabling system is the use of a set of standard networking devices, in accordance with the standard connection method to achieve the network cabling system. The biggest difference between structured cabling and conventional cabling systems is that the structure of the structured cabling system is independent of the location of the currently connected device. In the traditional cabling system, where the equipment is installed, where the transmission medium is to be laid. Structured cabling system is the first by the structure of the building, the building will be placed in all the equipment are pre-set the line, and then according to the actual connected equipment, by adjusting the internal jumper device, all the equipment connected stand up. The interface of the same line can be connected to different communication devices, such as telephone, terminal or microcomputer, or it can be a workstation or host or a new type of network equipment and intelligent equipment.
Reflect the rational design of the system ideas, but also to facilitate the latter part of the maintenance work
The structured cabling system (StrUCturedCablingSystems, abbreviated SCS) uses a modular design and a hierarchical star topology. It can adapt to any building or building wiring system. Its representative products are building and building complex cabling system (PremisesDistributionSystem, abbreviation PDS). In addition, there are two advanced systems, namely Intelligent Building Cabling System (IBS) and Industrial Cabling System (IDS). Their principles and design methods are basically the same, the difference is PDS to business environment and office automation environment. (HORIZONTALSUBSYSTEM) 3.

Notebook computer motherboard is the largest piece of computer inside the board, you need to disassemble to see, the next figure that is a large board. Main board is a rectangular circuit board, installed above the main circuit composed of the computer system, generally BIOS chip, I / O control chip, key and panel control switch interface, indicator plug, expansion slot, motherboard and card DC power supply connectors and other components.
