Article Introduction：Java I/O streams implement asynchronous I/O operations by using the classes provided by the java.nio package (including AsynchronousChannel and CompletionHandler). These classes provide methods for initiating asynchronous read (readAsync) and write (writeAsync) operations. This mechanism improves I/O performance by allowing applications to continue executing without waiting for I/O operations to complete.

Article Introduction：The "i/o" interface is located between the bus and the "i/o" device; the function of the "i/o" interface is to enable the CPU to connect I/O circuits and peripheral devices through the system bus. The CPU is connected to the "i/o" interface. o" device is connected, the "i/o" device cannot be directly hung on the system bus. It must be connected to the system bus through the "i/o" interface circuit.

Article Introduction：The i/o interface is a basic input and output port, which is prepared for the action of each device. Each device will have a dedicated [I/O] address to process its own input and output information; the CPU, external devices, and memory Both the connection and data exchange need to be realized through interface devices. The former is called the [I/O] interface, and the latter is called the memory interface.

Article Introduction：In Linux, the ".o" file refers to the target file, and ".o" is the abbreviation of object; the ".o" file in Linux is equivalent to the ".obj" file in Windows. The target file contains machine code and Data used by the code while it is running, such as relocation information, program symbol tables used for linking or debugging, and other debugging information.

Article Introduction：Everything in Linux is a file. Whether it is the character files we store on the disk, executable files or our I/O devices connected to the computer, they are all abstracted into files by VFS. For example, the standard input device is the keyboard by default. We are When operating the standard input device, you are actually operating a file with file descriptor 0 that is opened by default. All software needs to operate the hardware through the OS, and the OS needs the corresponding driver to operate all hardware. This driver is configured The corresponding configuration and usage of this hardware are explained. Linux I/O is divided into four types: blocking I/O, non-blocking I/O, I/O multiplexing, and signal-driven I/O. For I/O device drivers, two configurations are generally provided: blocking and non-blocking. I
