今日要点:
- 并行进程、进程间通讯及多任务
- 动词的五大类型
parallel processing(并行进程)
The ability to apply two or more processors to a single computation.
一种在单个计算机上运行两个或多个程序的能力。
-
parallel[ˈpærəlel]: 并行的,并列的
-

intertask communication(进程间通讯)
A mechanism used by tasks and interrupt service routines to share information and synchronize their access to shared resources. The most common building blocks of intertask communication are semaphores and mutexes.
一种被用来在任务和中断服务程序之间共享信息和同步它们对共享资源访问的机制。大部分进程间通讯的建立的基石是信号量和互斥。
-
mechanism[ˈmekənɪzəm]: 机制
-
semaphore[ˈseməfɔ:(r)]: 信号量
Multitasking (多任务)
The execution of multiple software routines in pseudo-parallel. Each routine represents a separate "thread of execution" and is referred to as a task. The operating system is responsible for simulating parallelism by parceling out the processor"s time.
伪并行运行的多个软件程序。每一个程序表现得像分开的“执行的线程”并且被看作是一个任务。操作系统通过分配处理器时间来模拟并行方式。
-
be referred to as sth: 被看作,被称为...
-
be responsible for sth(doing sth)负责某事(做某事)
-
to parce out 把…分成小部分
今日语法小知识: 动词
动词可以分为五大类型:
-
完全及物动词
complete transitive verb , c. vt. for short -
不完全及物动词
incomplete transitive verb , i. vt. for short -
不完全不及物动词
incomplete intransitive verb , i. vi. for short -
完全不及物动词
complete intransitive verb , c. vi. for short -
授予动词
dative verb , d. v. for short
其实这五种动词类型代表中英语中5大基础句型。具体我们在后面详解。
