motherboard wiring

computer motherboards are four-ply boards, six-layer board, the use of components and wiring are very sophisticated, dust in the motherboard accumulated too much, will absorb the moisture in the air, the dust will present a certain degree of conductivity, may be the main board of different signals to connect or to the resistance, capacitance short-circuit, Causes the signal transmission error or the work p

First, the introduction Today, most of the voice, data and image transmission in office buildings, buildings, university campuses, government departments and even residential communities in intelligent buildings are based on structured cabling systems on their physical structure. We know that in the Iso/osi protocol, the physical layer is the basis of the network system, all network communications rely on the physical layer of the cable to the voice, data to the destination. With the populariza

floppy disk boot, but can not enter the hard disk. Enter the BIOS in the "UTILITY" item for hard drive detection, the report first, second master and slave hard is "not detected". First remove the optical drive, a good data line test, enter the BIOS to detect the hard disk (wiring correct, hard disk jumper is also correct), still can not find the hard disk, the data line on the motherboard on the IDE2 por

introduce USB interfaces USB interface Most popular interface with up to 127 peripherals supported 500mA current can be obtained from the motherboard, hot-swappable, truly Plug and play LPT interface (common port): typically used to connect a printer or scanner Motherboard plane Four-layer or six-layer board

What is the difference between a H67 motherboard and a H77 motherboard? As shown below: H67 and H77 The difference is big, I want to buy a can use Ivy Bridge processor motherboard, is going to buy a new i5 3550 of the processor, want to know with the motherboard to choose which Compare the price H67 and H77 The diffe

It is worth learning about the Integrated Wiring System. This article comprehensively introduces the Integrated Wiring System from two aspects: the characteristics of the Integrated Wiring System and the system introduction, I also hope to teach you more knowledge. Overview The Integrated Wiring System is a modular an

Integrated wiring system in China has more than 10 years of history, wiring engineering after 10 years of development has become increasingly mature, the performance of transmission media has been increasing, wiring scale is also more and more large, but cabling system management is often overlooked. We know that the flexibility of the integrated

pay attention to the chassis air duct, so that the internal chassis cooling fan to achieve better heat dissipation optimization, as shown in the following figure. Optimize the knowledge of cooling chassis duct Chassis fan power supply is introduced here, the chassis fan power wiring is mainly to pay attention to positive and negative, fan interface no matter how many pins can be connected, according to the fan power interface, choose to

How to become an excellent Integrated Wiring Training Instructor From: www.anheng.com How to become an Integrated Wiring Training Instructor(1) proficient in general wiring system specificationsTo become a training instructor for the Integrated

. On ordinary computers, only USB ports and IEEE 1394 FireWire interfaces are commonly used to support hot-swappable (which can be plugged in without a host). In addition, the plug-and-unplug interface should be pulled out parallel to prevent physical deformation of the interface. Today's computer motherboards are mostly four-layer board, six-layer board, the use of components and wiring are very sophisticated, dust in the

Application System A system that transmits information in a way that can operate normally on an integrated wiring. Cable Cable refers to the information technology equipment connected to cables, optical cables and a variety of soft cables. Integrated wiring Integrated wiring is a information transmission channel composed of cable and related hardware, it can supp
