In multi-threaded operating systems, each system is implemented differently. A user-level thread is implemented in some systems, and a kernel-level thread is implemented in some systems1. Kernel-level threading:(1) thread creation, revocation, and switching, all require the kernel to implement directly, that is, the kernel to understand each of the threads as a s

The ARM + LINUX route focuses on the embedded Linux operating system and its application software development goals: 1) master the structure and principle of mainstream embedded microprocessor, which is initially set to ARM9) 2) an embedded operating system must be initially set to uclinux or linux. The version is to be determined) 3) be familiar with the embedded software development process and build at

transmit any amount of data in the form of bits. A named pipeline can also combine datasets into a data block called a message. A named pipe can even connect to multiple processes over a network. However, Windows 9x does not support creating named pipelines. It can only be created on Windows NT, Windows 2000, and Windows XP operating systems. When discussing pipelines, two processes are involved: Custome

Introduction to operating systems A computer system can receive and store information according to human requirements. It can process and provide the required results. The results (output information) depend on the received information (input information) and corresponding processing methods. 1. Learning Process: I used to learn some related operating system know

Simply put, x86 represents a 32-bit operating system x64 represents a 64-bit operating system. If your CPU is more than two cores, it certainly supports 64-bit operating systems. If your computer has more than 4G of memory, it will use a 64-bit system, because 32-bit Windows 7 or Vista, the largest only support 3.25G o

handle multiple tasks, not necessarily at the same time. The key to parallelism is the ability to handle multiple tasks at the same time.5. Synchronous and asynchronousSynchronization means that when a process executes a request, if it takes a while for the request to return the information, the process waits until the return message is received, and the process does not need to wait all the time, but continues to perform the following operations, regardless of the state of the other process.
