;The role of the operating system(The operating system is actually the core and the interface tools it provides)The core layer of the operating system is directly referenced to the hardware specifications, so the same operating system program cannot operate under a different hardware architectureThe operating system only manages the entire hardware resource, including CPU, memory, input and output devices, and file system filesThe development of the application is a reference to the development

-line management, and so on, and many of the command line applications under Linux system to implement management files, systems, partitions, etc. Purely logical function structure mode, function Application object, function of their own level and logic is also different, pure and meticulous in-depth study of the interactive medium, the command structure enough analysis, of course, client task analysis Such a good weapon naturally also need to arm to use. This kind of interaction is more like a

system, which is called the ABI. The executable program on Windows supports the Exe,msi format, while Linux supports the ELF format, and each application has an execution entry indicating the supported binary format. in short, the source program developed on Windows, which can be compiled on Linux, requires the same API on both sides, and on Windows it is possible to build on Windows to run on Linux, on both sides of the ABI.This article is from "Snail Little Fly" blog, reproduced please contac

success is benefiting from the application of interdisciplinary disciplines, in order to enable scientists to break through the traditional way of thinking, to open up an unprecedented field of thinking, burst out the spark of innovation, to establish a unique, innovative ideas.The intersection, infiltration, integration and innovation of disciplines are the important characteristics of the trend of scientific synthesis and differentiation, and also the inevitable trend of discipline developmen

control of the data bus to the host and surrender control if the host allows it. Therefore, when the DMA mode for data transmission, the bus control is controlled by the DMA controller, after the completion of data transmission, the DMA controller will return the bus control to the host. The DMA controller or interface typically consists of four registers:Status control registers, data registers, address registers, and byte counters.These registers need to be initialized before the information
