In these two days, the number of Chinese passengers from Beijing to the United States was exceptional, and most of them went to CES (American Consumer Electronics Show). Every January, Las Vegas, a city full of glamour, will make the world crazy because of CES. Participants sitting on the plane, one topic is who is the most eye-catching booth, and the other topic is the hidden doorway of the gambling. CES and Las Vegas are both big gambles. As the vane of the global consumer electronics industry, any product shown here may be the next disruptive industry revolution. Who will be the next lucky one among more than 3,500 exhibitors this year? On the afternoon of the 4th local time, two days before the opening of the CES in 2015, the reporter of the “First Financial Daily†saw the style of innovative consumer electronics products in 2015. Some novelty products are amazing: for example, small smart cameras that can be worn, 3D food printers, etc. There is no doubt that the Internet of Things, smart homes and wearables will be a hot spot for CES in 2015. This is a great platform. Since the middle of the last century, too many new products that shocked the world have been released here. For a large number of Chinese companies that want to build brands around the world, CES is the king and first choice in the show. Four major trends “In the field of macro technology, CES is still the most important event of the year.†Ben Keane, a consultant at IHSTechnology, a market research organization, has always believed this. This year is Keane's 20th participation in the CES conference. He said: "In the past, the content of CES was inseparable from brown products. That is to say, all products are closely related to television or technology. But now, the phenomenon of integration of many fields is incredible." On the afternoon of the 4th local time, Dr. Shawn G. Dubravac, chief economist of CES organizer CEA (American Consumer Electronics Manufacturers Association), gave a speech titled "Digital DesTIny". He believes that the digital world has four major trends in the future: one is the digitization of physical space; the second is the penetration of logic; the third is my Internet; the fourth is fragmentation innovation. The so-called digital physical space, for example, is that the toilet in the bathroom will also be connected to the Internet; baby clothes can also be put on wearable devices, so that parents can always know if the baby is asleep or has woken up. Physical space forms data, data processing affects physical space, analyzes behavior - forms data - brings changes - analyzes behavior, forms a cycle, so this year's CES will see technologies that make home smarter, such as intelligent Air ventilation system, APP for managing pets, smart watches, etc. In addition, there are 3D printing technology, drones, 4K ultra-HD smart TVs and so on. ShawnG.Dubravac predicts that the global shipment of smart watches will reach 10.8 million in 2015; the global shipments of small drones (usually used for networked smart shooting) will reach US$130 million, an increase of 50% year-on-year. Being in a digital physical space will form "my Internet." Dr. Shawn G. Dubravac said that wearable devices such as smart connected cars and smart bracelets will increase personal data more than the PC era and the smartphone era. The combination of intelligence and all aspects of life also brings many opportunities for “fragmented innovationâ€, such as remote cooking through a smartphone app. Internet of Things According to John Karan, general manager of communications, media and technology at Accenture Consulting, the biggest attraction of CES2015 is the Internet of Things. This year's show will feature 900 exhibitors exhibiting IoT technologies and products, including television, kitchen supplies, lighting and health and sports equipment. “In the past few months, you may have heard a lot about the combination of IoT and high-tech business opportunities. You may have more discoveries at CES2015.†Karan said that the Internet of Things makes intelligence through a global network. Communication between products and even between products and people. The Internet of Things market has opened up, and CES2015 will be the best place to showcase this market prospect. Industry insiders expect that the five factors driving the growth of the IoT market will be the hot spot at this year's CES show: First, the large-screen mobile phone continues to be the focus of the spotlight, and the screen resolution and quality will become the focus of attention. TV manufacturers will also try their best to seize the 4K market. The lack of 4K content is one of the bottlenecks restricting market development, and vendors will solve this problem through new hardware and streaming services. In addition, there are information security risks. People are worried that with the high-profile launch of new products in the high-tech industry, is it that consumers' personal information becomes less secure? The Internet of Vehicles and Seamless Experience is another key connection point for the Internet of Things. Today's cars are no longer simple vehicles. It is more like a mobile phone with wheels. CES has also become a new concept for car manufacturers. One of the most important stages. From the show to the market On the afternoon of the 4th, local time, the reporter of China Business News has seen many novelty products, including smart flowerpots that can automatically control watering flowers and monitor the intelligence of pet dogs. Wearable devices, smart electronic locks with mobile APP switches, small wearable smart cameras, smart basketballs, 3D food printers, etc. A wide range of smart applications has also spurred global sales of smartphones. Research firm GFK analyst Steve Koenlg said in a speech on the 4th local time that the sales of smartphones in mobile phones, TVs, computers, tablets, digital cameras and other display products will increase from 37% in 2014 to 2015. 40%; global smartphone sales are expected to reach approximately 1.5 billion units in 2015, up 19% year-on-year, with China's sales in the global market expected to reach 34%. SteveKoenlg said that in 2014, the global technology industry output value increased by 1% year-on-year. The Asian market led by China led the development of the technology industry. He asked: "The global consumer electronics technology industry is still driven by smartphones and networked devices, but can maintain How long?" On the 5th local time, the global consumer electronics manufacturing giant will hold a number of press conferences before the opening of CES, perhaps finding more answers.
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 maximum synchronous transmission rate of the original SCSI standard was 5MB / S (scsi-1, also known as narrowscsi, in 1986, the maximum support for seven devices, the clock frequency was 5MHz), and the later SCSI II specified two options for increasing the speed. One is to increase the frequency of data transmission, namely fast SCSI (in 1994, the maximum support for 7 devices) is 10 Mb / S (10 MHz) because the frequency is doubled; the other is to double the transmission frequency and increase the width of the data path from 8 bits to 16 bits. The maximum synchronous transmission speed of widescsi is 20MB / S (the clock frequency is 10MHz, in 1996, the maximum support for 15 devices).

The third generation of SCSI appeared around 1995, but there was no unified standard
1. Ultra SCSI with maximum synchronous transmission speed of 20MB / S (also known as FAST-20 SCSI, clock frequency of 20MHz);
2. Ultra wide SCSI with maximum synchronous transmission speed of 40MB / S (same as 1);
3. Ultra2 SCSI with maximum synchronous transmission speed of 40MB / S (also known as fast-40 SCSI, clock frequency of 40MHz, 1997).
Later, some newer SCSI standards appeared
1. Ultra2 widescsi with maxmum synchronous transmission speed of 80mb / S (clock frequency of 40MHz);
2. Ultra 3 SCSI with maximum synchronous transmission speed of 160MB / S (also known as ultra-160 or fast-80 wide SCSI, clock frequency of 40MHz plus double data rate, 1999);
3. Ultra 320 SCSI with maximum synchronous transmission speed of 320mb / S (also known as ultra 4 SCSI, clock frequency of 80MHz plus double data rate, 2002); 4. Ultra 640 SCSI with maximum synchronous transmission speed of 640MB / S (clock frequency of 160MHz plus double data rate, 2003, is the latest SCSI standard)
This interface is a convenient interface standard for system integration, cost reduction and efficiency improvement. More and more devices will use the SCSI interface standard. Therefore, there are many hard disks and SCSI CD-ROM drives with SCSI interface. However, due to the cost problem, they are mainly used on medium and high-end servers and workstations.
