汉英对照:
Chinese-English Translation:

UNIX结构分为核心层,系统调层和应用层。用于进程管理、文件管理、终端状态等。

UNIX structure is divided into core layer, system layer and application layer. It is used for process management, file management, terminal status, etc.

UNIX 结构分为核心层,系统调层和应用层。用于进程管理、文件管理、终端状态等。

UNIX structure is divided into core layer, system layer and application layer. It is used for process management, file management, terminal status, etc.

UNIX 系统分为三层:

UNIX system is divided into three layers

内层:核心层,UNIX 内核,是 OS 管理和控制中心,常驻内存。

Inner layer: core layer, UNIX kernel, OS management and control center, resident memory.

中间层:系统调用层,界于核心层和应用层(外层)之间,是供程序员设计、开发应用程序时调用的。UNIX 系统调用包括:进程管理、文件管理、终端状态等。

Middle layer: system call layer, between the core layer and the application layer (outer layer), is used by programmers when designing and developing applications. UNIX system calls include: process management, file management, terminal status, etc.

外层:应用层,包括各种开发工具、高级语言编译器、网络通讯处理程序等。所有应用层程序都是在 shell(命令语言解释程序)的管理和控制下为用户服务的,是面向用户操作的界面。

Outer layer: application layer, including various development tools, high-level language compiler, network communication processing program, etc. All application layer programs are managed and controlled by shell (command language interpreter), and they are user-oriented interfaces.

UNIX 系统在结构上分为核心程序(kernel)和外围程序(shell)两部分,而且两者有机结合成为一个整体。核心部分承担系统内部的各个模块的功能,即处理机和进程管理、存储管理、设备管理和文件系统。核心程序的特点是精心设计、简洁精干,只需占用很小的空间而常驻内存,以保证系统的高效率运行。外围部分包括系统的用户界面、系统实用程序以及应用程序,用户通过外围程序使用计算机。

UNIX system is divided into two parts: kernel and shell, and they are integrated into a whole. The core part undertakes the functions of each module in the system, namely processor and process management, storage management, device management and file system. The core program is characterized by careful design, concise and concise, which only needs to occupy a small space and stay in memory to ensure the efficient operation of the system. The peripheral part includes the user interface, system utility and application program of the system. The user uses the computer through the peripheral program.

UNIX 系统的文件系统是树形结构。它由基本文件系统和若干个可装卸的子文件系统组成,既能扩大文件存储空间,又有利于安全和保密。

UNIX system is a tree structure. It is composed of basic file system and several removable sub file systems. It can not only expand the file storage space, but also be conducive to security and confidentiality.

经过 30 多年的不断发展,UNIX 的一些基本技术已变得十分成熟,有的已成为各类操作系统的常用技术。无数的实践表明,UNIX 是能达到大型主机可靠性要求的少数操作系统之一。目前许多 UNIX 大型:主机和服务器在国内外的大型企业中每天 24 小时不间断地运行。例如,不少大企业或政府部门,将其整个企业/部门信息系统建立并运行在以 UNIX 为主服务器的客户机/服务器架构上。

After more than 30 years of continuous development, some basic UNIX technologies have become very mature, and some have become common technologies of various operating systems. Numerous practices show that UNIX is one of the few operating systems that can meet the requirements of mainframe reliability. At present, many UNIX large-scale hosts and servers run 24 hours a day in large enterprises at home and abroad. For example, many large enterprises or government departments set up and run their whole enterprise / department information systems on the client / server architecture with UNIX as the main server.
