as a boot device. Of course, linux is usually started from a hard disk. The MBR (Master boot Record) on the hard disk contains a basic boot loader, which is a 512-byte sector located in the first sector of the disk (0 head, 0 track, 1 sector ). When the MBR is loaded into RAM, the BIOS transfers the control to the MBR.Boot the operating system kernel and prepare for the protection mode Located in MBRMain boot loaderIs a 512-byte image, which not only containsBootload program codeAnd contains a

difficult to distinguish between true and false. David Howard, an electronics engineer at York University, and Alan Chalmers, a high-fidelity Graphics Expert at Warwick University, recently invented a method to generate electronic smells-to work together on this project. Users wearing this new Virtual Reality (VR) helmet can smell the flowers in the Japanese Garden, the researchers said, when watching a VR hunt, you can hear the roar of lions and oth

storage Linux supports a wide range of DAS interfaces, including the old standard for Advanced Technology Attachment (ATA)-electronic Integrated Drive [IDE] (Integrated Drive Electronics [IDE]) /ATA-parallel SCSI and Fiber Channel and new storage interfaces, such as serially connected SCSI (Serial Attached SCSI, SAS), Serial ATA (Serial ATA, SATA) and external SATA (external SATA, eSATA ). You will also find advanced storage technologies such as USB3

skills, professionalism, value and motivation. We will dissect them one by one. In terms of knowledge and skills, HR generally does not focus on the courses you have learned or the number of points you have received, but on the major and contact list you have learned. At this time, compound talents have obvious advantages. For example, a student of this science electronics or graduate school of law can easily find the position of intellectual prope

from 23% in the same period last year to 18%, and shipments increased to the lowest level in history. According to the report, South Korea's Samsung Electronics shares 33% of the global smartphone market in the quarter, hitting a record high for the company, up from 29% in the same period last year. According to the report, shipments of smartphones in the global market of Samsung Electronics increased by 5

Since my professional scores cannot be changed, I have to highlight myself in other aspects. In this process, I participated

least we can improve our living environment. We can improve our home environment, use full digitalization, and use a mobile terminal to control all the electronic devices in the home, such as microwave ovens, water heaters, televisions, and refrigerators. We can control it as long as it is a smart device. [Software is a hardware programming, using software to write hardware processing logic] We assume that this terminal device is called the Home Device Control Center. We need to develop su

The editor recommends that the Second Edition further analyzes the relationship between ERP and other application systems, and adds discussions on "finance-centric" and other software design ideas. In the implementation of ERP, the main issues have been discussed. Some key issues in each chapter are further described, such as the early stage, JIT and Kanban operations, MES and APs. In addition, the missing references of version 1 are supplemented.The book ERP-starting from internal integration i

completely overlapping commands . That is to say, when executing the previous instruction, the next instruction can be taken out and decoded simultaneously, which greatly improves the speed of the microprocessor. In addition, transmission between the program space and the data space is allowed , which increases the flexibility of the device. The working principle is to receive analog signals and convert them0Or1Then, modify, delete, and strengthen the digital signal, and interpret the digital
