1、task 可以理解为一个LINUX PROCESS。最著名的定义TASK的数据结构叫做struct task_struct, 在linux\sched.h中。我觉得这个名字起得不好。因为大家都已经对PROCESS, THREAD之类得观念很熟悉了。现在又冒出来个TASK,很容易让人搞混。不过也许是历史原因吧。这个TASK一直保留着。 在task_struct 中有一堆
线程(thread) 与进程(process)是操作系统中两个非常重要的概念,也经常出现在技术类岗位面试中,并且根据面试者的回答侧重点如内存结构,线程通信等等进行展开。 关于二者的概念与区别,相关的书籍博客进行了各类阐述,较为繁杂。(下图显示了其中一部分) 本文从底层结构中去分析二者的区别,进而可以轻松理解二者在宏观上的差...
A threat is a unit of execution within a process. A process has a at least one threat, it is called a Main Thread. It is not uncommon for a process to have many threats, each threat has his own stack, earlier we mention registers , program counters, stack pointers as being part of ...
一个process可以包含多个thread,且thread可以共享resource 当然第一次开启应用程式,Android将启动一个只有一个执行线程的进程,而这个线程就是mainthread,因为主要用来处理与使用者的沟通,也因此叫做UIthread 再来简单的整理TASK,PROCESS,THREAD 我们可以把TASK看成一个应用程式本身,当使用者点击应用程式以后,就启动了TASK,...
Activity, Service,Task, Process and Thread之间到底是什么关系呢? 首先我们来看下Task的定义,Google是这样定义Task的:a task is what the user experiences as an "application." It's a group of related activities, arranged in a stack. A task is a stack of activities, not a class or an element ...
As Linux system users, we never have to create the internal data structure for the process. However, it’s essential to understand the Linux process’s internal data structure.Linux creates every process using a data structure in C calledtask_struct.The Linux kernel holds them in a dynamic li...
TASK_STOPPED: The process execution is stopped, it's not running, and not able to run. On receipt of signals like SIGSTOP, SIGTSTP, and so on, the process arrives at this state. The process would be runnable again on receipt of signal SIGCONT. ...

A thread is a sequence of executable commands that can run concurrently within a process, while a process is a complete program in execution, including its code, data, and system resources.
