The US Defense Department announced last month that it will suspend the US-Korean "Freedom Guardian" military exercise indefinitely to show its support for the outcome of the meeting between the US and North Korean leaders. As a major measure to ease the situation on the Korean Peninsula, the cancellation of the US-South Korea military exercise has aroused widespread concern. However, the latest news shows that there may be other hidden feelings behind the move to stop the US-South Korea military exercise.
Reuters reported that a US government official revealed that the expenses of the US-South Korea military exercise had previously attracted President Trump's complaint. He used the "expensive and outrageous" to describe the funds for this military exercise. Later, the military exercise was cancelled, and the actual amount of this funding may reach 14 million US dollars (about 92.67 million yuan).
According to reports, Trump has repeatedly stated that his own action to stop the military exercise has saved the United States a large sum of money. He also admitted on Twitter that the US-South Korea military exercise was stopped under its own "suggestions."
However, the US officials who disclosed the number of military exercises budget did not disclose the details of the funds and the items included in the media. The Pentagon has never announced the total expenditure of various military exercises in the United States and South Korea each year.
In addition, the budget of the US and South Korea military exercise of 14 million US dollars was also compared with the other money the US government intends to spend. It is said that the US Boeing Company previously obtained a contract worth nearly 24 million US dollars (about 159 million yuan), intending to upgrade the two refrigerators that store food on the presidential plane "Air Force One". However, as Boeing will also deliver a new aircraft to the US government for conversion to a new generation of Air Force One, the refrigerator upgrade contract was eventually cancelled.
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.
SCSI-3
In 1995, the more high-speed SCSI-3, called ultrasci, was born, and the data transmission rate reached 20MB / s. It increases the synchronous transmission clock frequency to 20MB / s and improves the data transmission rate. If 16 bit wide mode is used, the data transmission rate can be increased to 40MB / s. This version of SCSI uses a 68 pin interface, which is mainly used on hard disks. The typical characteristic of SCSI-3 is that the bus frequency is greatly increased and the signal interference is reduced to enhance its stability.
There are many models of SCSI-3. Ultra (FAST-20) has a transmission frequency of 20MHz, a data bandwidth of 8 bits and a transmission rate of 20MBps
Ultra wide has a transmission frequency of 20MHz, a data bandwidth of 16 bits and a transmission rate of 40mbps
The transmission frequency of ultra 2 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 80 Mbps
The transmission frequency of ultra 160 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 160 Mbps
The transmission frequency of ultra 320 is 80MHz, the data bandwidth is 16 bits, and the transmission rate is 320mbps
The transmission frequency of ultra 640 is 160MHz, the data bandwidth is 16 bits, and the transmission rate is 640mbps
