The real reason for investing 1 billion U.S. dollars, Ali Google, and betting on AR/VR?

According to foreign media reports, according to an investment bank’s Digi-Capital report, although Alibaba has just begun, companies such as Alibaba, Google’s parent company Alphabet, Spark Capital, and Temasek Capital Ptd. Ltd. are already in the fourth quarter. Invested $1 billion in AR/VR. This is only the second quarter when AR/VR investment totals more than $1 billion (the other is the first quarter of 2016). With the launch of AR platforms by Apple, Alphabet, and Facebook, the AR user base and business model are gradually shaping.

In the field of augmented reality, virtual images appear in real rooms or other real environments, just like Pokémon games. In virtual reality, all the environments shown on a helmet or other screen are virtual.

In the fourth quarter, most of the AR/VR investment funds came from two financing activities: In October, Magic Leap Company raised 502 million US dollars in the D-round financing activities; in November, the Elven Pokémon game. Producer Niantic raised 200 million U.S. dollars in Series B financing.

Temasek, EDB Investments Pte. Ltd., Brazilian Grupo Globo and Janus Henderson, and existing investors of Magic Leap, Alibaba, Google, Fidelity Management and Research (Fidelity) Management and Research Co., as well as other companies, participated in this financing activity.

Magic Leap has been developing augmented reality user interfaces and software, but so far it hasn’t had any products—whether physical or virtual—that can be sold to you. In the total AR/VR financing amounting to US$1.2 billion in the first quarter of 2016, the company’s financing amount reached US$800 million.

Although the investment made by Magic Leap Company is enough to show that people's confidence in AR/VR is greatly increased, the “Princess Pokemon” game launched in summer 2016 is really a sensational effect. "The game "Princess Pokemon" proves that AR/VR can also become a hot spot." Ben Schacter, an analyst at Macquarie Capital earlier this year, said in a research briefing, "What matters is that We expect large game publishers will be more willing to invest more in developing high-quality AR games because everyone wants to replicate the success of Pokémon."

Niantic's investor, Spark Capital, has extensive investment experience in AR/VR. The company is also an investor in Oculus VR. In 2014, Oculus VR was acquired by Facebook for $2.3 billion.

The emergence of Apple's ARKit augmented reality platform, Google ARCore, and Facebook's Camera Effects represents an important moment in the development of augmented reality business models.

“ARKit, ARCore, and Camera Effects are estimated to reach 900 million users by the end of next year, and by the end of 2021, it is estimated to exceed 3 billion users. However, it may take 12 months for mobile AR startups to achieve greater revenue growth. "Investment bank Digi-Capital said.

"Long-term dominant AR developers may honor the AR ticket they hold, but this may not happen until 2019," said the investment bank.

SCSI Connectors

A Small Computer System Interface (SCSI) connector, also pounced as [scuzzy" connector, is used for physically connecting and transferring data between computers and peripheral devices.

SCSI is the small computer system interface, which is an independent processor standard used for the system level interface between computer and intelligent devices (hard disk, floppy, optical drive, printer, scanner, etc.). It is an intelligent universal interface standard, which has the function of communicating with various types of peripherals. SCSI uses the standard software interface of ASPI (SCSI programming interface) to make the driver communicate with the SCSI adapter installed inside the computer. SCSI interface is widely used in high-speed data transmission technology on minicomputers. SCSI interface has many advantages, such as wide application range, multitask, wide bandwidth, low CPU utilization, and hot plug.


SCSI connectors type and interfaces

Centronics 50-pin connector: The Centronics 50-pin connector was once the most widely used SCSI connector. An external connector only, the Centronics is a SCSI-1 connector that looks the same as the Centronics cable that attaches to a parallel port printer. The Centronics 50-pin cable comes in male and female styles, and gender changers and cable converters are commonly available. Although used on older SCSI devices and external drive enclosures, this interface is no longer heavily used, due to its slow speed and short cable lengths.
High-density 50-pin connector: The high-density 50-pin connector is used on scanners and Jaz drives. It is one of the more common SCSI connectors and is usually used to connect SCSI-2 devices. Both ends of the cable are usually 50-pin male, while the sockets on the host adapter and external devices are 50-pin female.


DB 25-pin connector: The DB 25-pin or D Sub 25 is by far the most widely used connector. This connector is used for parallel and serial printers in addition to the many other devices available. Both ends of the cable are usually 25-pin male, while the sockets on the host adapter and external devices are 25-pin female. This cable is almost always an external connector.
Note: DB-25 SCSI CABLES are not compatible with and should not be used as serial or printer cables; serial cables and printer cables should not be used or attached to DB-25 SCSI adapters. You can short out the SCSI host adapter or the motherboard by using the wrong cable. Marking cables is the best way to avoid this.
IDC50 connector: The IDC50 is the most common internal SCSI connector. It is very similar to the standard IDE internal ribbon cable. The IDC50 SCSI cable is considerably wider then an IDE ribbon cable; in fact, it is usually the widest standard internal cable in use. This is a standard SCSI-2 10MBps internal SCSI cable. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often expensive and require a large case, as the cables may be four or five feet long.
High-density 68-pin connector: The high-density 68-pin connector is the SCSI connector of choice for SCSI-3 host adapters and peripherals. There is an internal ribbon cable version that looks very similar to the IDC50 connector. Many low-end cables have only two or three connectors, allowing for one or two devices to be attached to the cable. Seven-device cables are available, though they are often very expensive and require a large case, as the cables may be three or more feet long. Both ends of the external cable are usually 68-pin male, while the sockets on the host adapter and external devices are 68-pin female.


SCA 80-pin Micro-Centronics connector: SCA stands for Single Connector Attachment, a type of disk drive connector that includes connection pins for the power cables as well as the data wires. A SCA connector uses an 80-pin plug and socket to connect peripherals. This connector combines power, data channel, and ID configuration for fast installation and removal. SCA connectors are typically found only on high-end SCSI hard disks. The SCA interface was designed to provide a standard connection for systems using drives that can be hot-swapped. SCA makes swapping SCSI hard drives much easier than with traditional SCSI cables, plugs, and sockets. An adapter enables SCA drives to fit into standard SCSI enclosures.

SCSI SFF 8482: Also called "4x internal" by some vendors. This is a connector with the same form factor as SATA with the addition of a "bump" to key it specifically for SAS. (SATA drives can be plugged into SAS controllers, but SAS drives will not function with a SATA controller; hence, the necessity for the key bump on the connector.) As the name says, it's meant to be used internally, i.e., inside the computer case.

SCSI SFF 8484: Also called "32-pin" or "MultiLane". This is a high density connector usually intended to plug into the motherboard, controller, or backplane itself. Cables with this connector on one end usually have four individual SFF 8482 connectors on the other.
Serial Attached SCSI SFF 8470: Also called "4x external" by some vendors. This is simply a version of the SFF 8484 that's meant to be used with external (i.e., not located within the case) drives.
