Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
The last SCSI device in the SCSI chain uses a terminator, and the intermediate device does not need a terminator. Once the terminator is used by the intermediate device, the SCSI card cannot find the future SCSI device. If the last device does not use a terminator, SCSI will not work properly. Terminator is composed of resistors, located at the end of the SCSI bus, to reduce the mutual influence of the signal, maintain the constant voltage on the SCSI chain.

The LED TV price reduction information released recently from the color TV giant indicates that the Spring Festival color TV promotion war started ahead of schedule. Following the high-profile announcement of Zhongwei Feng, general manager of Skyworth Guangdong Branch, Skyworth’s LED TV price in the Spring Festival season will drop by as much as 30%. Gong Zhiping, general manager of TCL Guangzhou Branch, said in an interview yesterday that in addition to pushing LED Outside of TV, TCL will also have a big move in the field of Internet TV this year.
The reporter noted that in the new round of LED TV promotion boom, in addition to Skyworth, TCL, Hisense and other domestic color TV giants have lowered their prices, Samsung, Sony and other foreign brands have also joined the huge price reduction camp, during the period, domestic The price of the 42-inch LED TV has fallen below the 9,000 mark, and the drop is close to 30%.
Compared with CCFL (Cold Cathode Fluorescent Lamp) backlit LCD TVs, LED backlight TVs are currently not popular in the market. However, as one of the main themes of global economic development, the prospect of low carbon economy is undoubtedly quite broad, and the LED industry is just right. It fits this theme and is generally optimistic.
It is also based on this, in recent years, not only Samsung, Sony, Sharp and other global consumer electronics companies have gradually turned their attention to the field of LED TV, Skyworth, TCL, Hisense and other domestic color TV manufacturers have also begun to make big strides in the field of LED TV.
Recently, the reporter found that Guangzhou Suning, Gome and other home appliance stores found that the overall price of LED LCD TVs was quickly pulled down by the domestic flat-panel TVs such as Skyworth, TCL and Konka, and gradually narrowed the price gap with ordinary LCD TVs. Some of the domestically produced 42-inch LED TVs have fallen below the 9,000 mark, a drop of nearly 30%, while the price of foreign-branded products of the same size is around 12,000 yuan, a drop of more than 20%.
The vice president of Konka Group, Mu Gang, announced that the five LED production lines built by Konka will be put into operation in March this year. With the increase of independent production capacity, Konka LED TV prices are expected to drop by nearly 30%. Analysts pointed out that with the adjustment of the price of upstream components and the improvement of the layout of domestic TV sets in the LED TV industry chain, in the following year, the price of LED TVs reflected in the market will gradually be attributed to rationality. 
Most of the SCSI devices have built-in terminators and use a jumper to control on / off. The SCSI device is highly intelligent and can automatically control the terminator on / off. For example, if a hard disk is connected to a CD-ROM, the CD-ROM can work normally regardless of whether the terminator of the hard disk is on or off. However, when two hard disks are connected, the situation becomes more complicated. Before two Seagate hard disks are connected, one hard disk terminator must be off. Before a Seagate hard disk is connected to a quantum hard disk, a hard disk terminator can work normally regardless of whether it is on or off.
