尤晋元，上海交通大学计算机科学及工程系教授、博士生导师。在科研方面，主要从事操作系统和分布对象计算技术方面的研究；在教学方面，长期承担操作系统及分布计算等课程的教学工作。
主编和翻译了多本操作系统教材和参考书，包括《UNIX操作系统教程》、《UNIX高级编程技术》、《UNIX环境高级编程》和《操作系统：设计与实现》等。
二、unix什么？
Unix是20世纪70年代初出现的一个操作系统，除了作为网络操作系统之外，还可以作为单机操作系统使用。Unix作为一种开发平台和台式操作系统获得了广泛使用，主要用于工程应用和科学计算等领域。
UNIX是一个功能非常全面的操作系统，在某些方面超越Linux。
三、什么是unix？
UNIX是一个功能强大、性能全面的多用户、多任务操作系统，可以应用从巨型计算机到普通PC机等多种不同的平台上，是应用面最广、影响力最大的操作系统。 Linux是一种外观和性能与UNIX相同或更好的操作系统，但，Linux不源于任何版本的UNIX的源代码，并不是UNIX，而是一个类似于UNIX的产品。Linux是开发源代码的自由软件,UNIX是对源代码实行知识产权保护的传统商业软件.UNIX系统大多是与硬件配套的,而Linux则可运行在多种硬件平台上.UNIX是商业软件,而Linux是自由软件,免费、公开源代码的.UNIX(5万美圆)而Linux免费UNIX是命令行下的系统 linux是加了窗体管理的系统在对硬件的要求上,linux比unix要低,没有unix那么苛刻.在安装上linux比unix容易掌握.
四、Unix是什么？
Unix是操作系统
是一个强大的多用户、多任务操作系统，支持多种处理器架构，按照操作系统的分类，属于分时操作系统。
最早由KenThompson、Dennis Ritchie和Douglas McIlroy于1969年在AT&T的贝尔实验室开发。它的商标权由国际开放标准组织所拥有，只有符合单一UNIX规范的UNIX系统才能使用UNIX这个名称，否则只能称为类UNIX（UNIX-like）。
Unix 操作系统因其开放性、可移植性、多用户多任务以及稳定性等特点，加上本身强大的网络通讯功能，被广泛的应用在各主要行业中 。
UNIX用户协会最早从20世纪80年代开始标准化工作，1984年颁布了试用标准。后来IEEE为此制定了POSIX标准（即IEEE1003标准）国际标准名称为ISO/IEC9945.它通过一组最小的功能定义了在UNIX操作系统和应用程序之间兼容的语言接口。
五、UNIX创始时间？
unix是一个强大的多用户、多任务操作系统，支持多种处理器架构。按照操作系统的分类，属于分时操作系统，源自于1969年开始在美国AT&T公司的贝尔实验室开发的AT&T Unix。它的商标权由国际开放标准组织所拥有，只有符合单一UNIX规范的UNIX系统才能使用UNIX这个名称，否则只能称为类UNIX（UNIX-like）。
六、unix / linux
<>Unix/Linux: The Powerhouse of Operating Systems
Unix and Linux are two terms often used interchangeably in the realm of operating systems (OS). Both have gained immense popularity and are widely utilized in various domains, making them the go-to choices for many technological enthusiasts, developers, and organizations. Let's delve deeper and explore the world of Unix and Linux.
Understanding Unix
Unix, developed in the early 1970s, is a multitasking, multiuser OS. It was initially created for mainframe computers by a group of AT&T Bell Labs employees. Unix revolutionized the computing landscape with its powerful features like file manipulation, inter-process communication, and a hierarchical file system. It quickly became the foundation for several modern OS principles and concepts.
Unix offers a command-line interface (CLI) for interaction, allowing users to execute commands and scripts. It provides numerous utilities for file management, process handling, network communication, and more. Moreover, Unix's simplicity, stability, and scalability have contributed to its dominance in the industry.
The Rise of Linux
Linux, on the other hand, emerged in the early 1990s as a free and open-source OS kernel. Linus Torvalds, a Finnish computer scientist, spearheaded its development. He aimed to create an OS similar to Unix but accessible to everyone. With the Linux kernel as its core, different distributions or "distros" were created, such as Ubuntu, Fedora, and Debian.
This open-source model attracted a vast community of developers, resulting in continuous enhancements, bug fixes, and the availability of a rich set of software. Linux distributions can run on a wide range of devices, from smartphones and laptops to servers and supercomputers, offering flexibility and customization options according to specific needs.
Key Features and Benefits
Both Unix and Linux possess several remarkable features that contribute to their popularity:
- Stability and Reliability: Unix and Linux exhibit exceptional stability, rarely experiencing crashes or system failures. This reliability makes them ideal for critical applications and server environments.
- Security: Unix and Linux prioritize security, with built-in mechanisms to protect against unauthorized access, malware, and viruses. Their strong user permission model ensures data integrity and confidentiality.
- Flexibility and Customization: The modular nature of Unix and Linux encourages customization. Users can fine-tune the OS to suit their requirements, installing only the necessary components, thus optimizing resource utilization.
- Scalability: Unix and Linux handle diverse workloads efficiently, making them suitable for both small-scale systems and large enterprise environments. Scalability ensures seamless performance even under heavy usage.
- Open Source Community: Linux, being open source, benefits from a vast community of developers worldwide. This community continually enhances the OS, provides support, and fosters innovation.
Unix vs. Linux
While Unix and Linux share common roots and similarities, some key differences set them apart:
- Licensing: Unix systems are typically commercial and proprietary, requiring paid licenses, while Linux distributions are freely available.
- Brand Variants: Unix is largely represented by commercial variants such as HP-UX, AIX, and Solaris, each tailored for specific hardware platforms. Linux, on the other hand, offers a variety of distributions accommodating different user preferences and system requirements.
- Development: The development process of Unix is generally closed and controlled by specific vendors. Linux, being open source, is driven by community collaboration, allowing anyone to contribute to its development.
Industry Adoption
The impact of Unix and Linux on various industries is profound. They have become the backbone of critical infrastructures, powering servers, supercomputers, embedded systems, and the internet itself. Many organizations, including multinational corporations and government agencies, rely on Unix and Linux to meet their computing needs. These robust operating systems offer unmatched performance, security, and stability, fostering innovation and technological advancements.
Conclusion
Unix and Linux, with their rich heritage and extensive features, have certainly stood the test of time. They continue to evolve and dominate the operating system landscape. Whether you're an enthusiast, a developer, or an organization seeking a reliable and efficient OS, Unix and Linux are undoubtedly two powerhouses worth exploring and harnessing to propel your technological endeavors.
