Differences between LINUX and other operating systems

Article Title: differences between LINUX and other operating systems. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
It is very important to know how Linux differs from other operating systems. Here we mainly discuss the operating systems on PCs, such as MSDOS, Windows, and Unix. First, you must note that Linux and these operating systems can coexist on the same PC. You can run MSDOS, Windows, and Linux on one machine without any problems.
　　
　　 Differences between Linux and MSDOS
It is common to run Linux and DOS on the same machine. Many Linux users rely on DOS for text processing. Linux also provides similar functions, but it also needs to Run DOS and Linux at the same time for some other reasons. For example, file format conversion is a problem. Many commercial DOS software cannot be used in Linux, so they have to be used at the same time. DOS cannot fully utilize the functions of the microprocessor. On the other hand, Linux fully runs in the protection mode of the microprocessor, so all functions of the microprocessor can be fully utilized. Linux and DOS are essentially different. DOS cannot match other commercial operating systems, but it has gained a firm foothold in the personal computer field. No PC operating system has reached the popularity of DOS, because the DOS price is low. However, Linux is a free software, so users do not need to consider the price. The choice of Linux is clearly based on their expectations and needs. If you want to run the complete Unix at home and do not want to run Unix at a high cost on your PC, Linux is undoubtedly the best choice.
　　
　　 Differences between Linux and Windows
Like Linux, Windows is a fully multitasking operating system. They support the same user interface, network, and security. However, the real difference between Linux and Windows is that Linux is actually a Unix version, and the contribution from Unix is huge. What makes Unix so important? Unix is not only the most popular Operating System for Multi-User Machines, but also the basis of free software. On the Internet, a large number of free software is written for Unix systems. There are many Unix vendors, so there are also many Unix implementation methods. No individual organization is responsible for Unix distribution. At present, there is a huge force to promote the standardization of Unix community in the form of an open system. On the other hand, Windows is a dedicated system, which is designed by the company that develops the operating system. In this sense, this company is very profitable because it sets strict standards for program design and user interface design, which is totally different from those of open system communities. Some organizations are trying to standardize Unix programming interfaces. In particular, Linux is fully compatible with the POSIX.1 standard.
　　
　　 Differences between Linux and Unix
Unix and Linux on some PCs are similar in implementation. Almost all commercial Unix versions basically support the same software, programming environment, and network features. However, there are still many differences between commercial Linux and Unix versions. Linux supports different hardware scopes than commercial Unix. Generally, commercial Unix supports more hardware, but Linux supports more hardware. Note that Linux is at least as stable as commercial Unix. For many users, the most important factor is price. Linux is a free software that can be downloaded from the Internet. If the Internet access is inconvenient, you can obtain the Linux disk or CD-ROM through mail order very cheaply. Of course, you can also get it directly from your friends. The value of commercial Unix should not be devalued. In addition to the price of the software, you also need to pay the documents, after-sales support and quality assurance fee. These are important for large organizations, but PC users may not benefit from them. Many commercial companies, universities, and other organizations have found that running Linux on cheap pcs in laboratories is better than running commercial Unix on workstations. Linux can provide the workstation function on a PC, and the price of a PC is a fraction of that of a workstation. There are also some cheap Unix for PC, the most famous of which is ipvbsd. In many aspects, the iisbsd package is compatible with Linux, but Linux is more suitable for user needs. Most importantly, Linux development is open, and any volunteers can contribute to the development process. In contrast, objective BSD is developed by closed teams. In this way, there is a serious conceptual and Design difference between the two products: the objective of Linux is to develop a complete Unix system from the beginning; objective of objective BSD is to modify the existing BSD to fit the 80386 system.
