多任务(Multitasking— 操作系统一次运行多个程序或任务的能力。协作式多任务 OS,如 Windows 95/98,要求应用程序主动释放另一个程序请求的资源,以便另一个应用程序能够使用这些资源。抢先式多任务 OS(例如 UNIX/Linux、Windows NT/2000 或 OS/2)中,操作系统基于时间片或基于优先级命令应用程序释放资源时,应用程序释放资源,以便在其它程序需要资源时,正在使用这些资源的应用程序不会独占它们。(另请参阅“多线程”和“分时”。)
Multitasking – The ability of an operating system to run more than one program, or task, at a time. A cooperative multitasking OS, like Windows 95/98, requires one application to voluntarily free up resources upon request so another application can use it. A preemptive multitasking OS, such as UNIX/Linux, Windows NT/2000 or OS/2, frees up resources when ordered to by the operating system, on a time-slice basis, or a priority basis, so that one application is unable to hog resources when they are needed by another program.

多线程(Multithreading— 操作系统并发运行被分成子组件或多个线程的程序的能力。如果运用得当,多线程可以更好地利用处理器及其它系统资源。多线程编程需要多任务/多线程操作系统,例如 UNIX/Linux、Windows NT/2000 或 OS/2,这些操作系统能够并发地运行多个程序。字处理程序可以充分利用多线程,因为它可以在前台进行拼写检查,同时在后台进行存盘并将输出发送到系统打印假脱机程序。
Multithreading – The ability of an operating system to concurrently run programs that have been divided into subcomponents, or threads. Multithreading, when done correctly, offers better utilization of processors and other system resources. Multithreaded programming requires a multitasking/multithreading operating system, such as UNIX/Linux, Windows NT/2000 or OS/2, capable of running many programs concurrently. A word processor can make good use of multithreading, because it can spell check in the foreground while saving to disk and sending output to the system print spooler in the background.


NFS(网络文件系统,Network File System — 一种允许跨网络或因特网共享文件的文件系统。
NFS (Network File System) – A file system that allows the sharing of files across a network or the Internet.

面向对象(Object-Oriented— 一种软件开发方法,它为程序员提供标准可重用的软件模块(组件),而无需开发人员每次都编写定制编程代码。使用标准组件缩短了开发时间(因为其他程序员已经编写并测试了这些组件),并且通过使用相同的组件确保了程序具有标准的外观。
Object-Oriented – A software development methodology that offers the programmer
standard reusable software modules (components), rather than requiring the developer to write custom programming code each time. Using standard components reduces development time (because the writing and testing of those components has already been done by other programmers), and ensures a standard look and feel for programs using the same components.

OO— 参阅“面向对象”。
OO – See Object-Oriented.

开放源码(Open Source— 一个稍显模糊的术语,是指同源代码一起发布的软件。提供源代码这一事实并不一定意味着用户可以修改和重新分发源代码。这个术语有时可以和“免费软件”互换使用,尽管它们的意思并不总是相同。
Open Source – A somewhat ambiguous term that refers to software that is released with its source code. The fact that the source code is provided does not necessarily mean that users can modify and redistribute the source code. The term is sometimes used interchangeably with “free software,” although they are not always the same.

伪代码(P-codePseudo-code)语言 — 一种解释型语言。伪代码语言有点象个“混血儿”,执行方式介于编译型语言和解释型语言之间。和解释型语言一样,伪代码编程语言无需编译,在执行时自动转换成二进制形式。然而,和编译型语言不同的是,这种可执行的二进制文件是以伪代码的形式而不是机器语言的形式存储的。此外,不同于解释型语言的是,不必在每次运行该程序的时候,都必须将其转换成二进制。在第一次转换成伪代码后,以后每次执行都可使用该伪代码版本。伪代码语言(以及用它编写的程序)往往比编译型语言及程序慢,但比解释型语言快,它们通常具有访问一些低层操作系统功能的权限,但却不能直接访问硬件。它们不需要有时很昂贵的编译器,通常与操作系统包含在一起,有些伪代码语言比编译型语言更容易编程。伪代码语言的例子有 Java、Python 和 REXX/Object REXX。
P-code (Pseudo-code) Language – A type of Interpreted language. P-code languages
are something of a hybrid, falling between compiled languages and interpreted languages in the way they execute. Like an interpreted language, P-code programming is converted to a binary form automatically when it is run, rather than having to be compiled. However, unlike a compiled language the executable binary file is stored in pseudo-code, not machine language. In addition, unlike an Interpreted language, the program does not have to be converted to binary each time it is run. After it is converted to P-code the first time, the pseudo-code version is used for each additional execution. P-code languages (and thus their programs) tend to be slower than compiled languages and programs but faster than interpreted languages, and they generally have authorization to some low-level operating system functions but not direct hardware access. They do not require sometimes-expensive compilers, are often included along with operating systems, and some p-code languages are easier to program than compiled languages. Examples of P-code languages are Java, Python and REXX/Object REXX.

(Also, see Append Symbol and Redirection Symbol.)

移植(Port/Ported/Porting— 一个过程,即获取为某个操作系统平台编写的程序,并对其进行修改使之能在另一 OS 上运行,并且具有类似的功能。通常很少或者干脆就不尝试定制程序以利用新操作系统的特有能力,这与为某个特定操作系统优化应用程序不同。
