to meet the time requirements with certainty. It is difficult to define an embedded system. If you are interested, you can refer to the "embedded system". Generally, you can think of it as a board or a chip.Total Software and Hardware,Embedded systems must have strong support for real-time tasksTherefore, embedded systems generally adopt real-time operating syst
Many people, including me, have dreamed of rewriting Linux to become the Chinese operating system. Last year's "Computer" (36th "Linux Thought") once published in this regard: the use of C + + rewrite the Linux kernel and xwindows, to overcome the Linux to the common user too professional disadvantage, make it easy to install, easy to install and configure peri
I. Introduction to the operating system The operating system is a set of programs that can effectively block and manage the hardware and software resources of the computer, dispatch the various functions reasonably, and facilitate the user's use.1. Objectives and role of th
Ransomware virus in OS X system security risks of operating system X Mac hard disk being encrypted by hackers In the past, the security of OS X systems often gave users a sense of reliability and stability. However, with the increase in Mac user base and the increase in OS x information value, OS X has gradually become the target of hacker attacks in recent year
Operating System Concepts Learning note 15 memory management (i) backgroundMemory is the center of modern computer operation. Memory has a very big group of words or bytes, and each word or byte has its own address. The CPU extracts instructions from memory based on the value of the program counter (PC), which can cause further reads and writes to a specific memo
