This article shows you what are the five misunderstandings that must be known in the learning of Linux operating system. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

It is difficult to develop applications, only suitable for the network, and so on. These comments on Linux are only in the view of some people who do not know Linux. Once you really know Linux, you will be conquered by the charm of Linux.

Misunderstanding one

It is difficult to develop and apply

There was some truth in this statement three years ago. In the past, it was difficult to develop applications for Linux using traditional tools. Traditional GCC and Emacs are difficult to learn and do not reach the level of efficiency required by enterprise developers. Now Linux has a fully functional, visual, fast programming tool-Kylix, which completely solves this problem. Kylix adopts the "drag and drop" method familiar to Win 32 developers to design the WYSIWYG user interface, which greatly improves the development efficiency of GUI applications (especially commercial and enterprise database applications) on the Linux platform, and makes countless Win 32 commercial applications transplanted to the Linux platform.

Misunderstanding 2.

Network only

Linux is almost synonymous with the network, and there are a large number of Linux supporters on the network. With the addition of more and more Linux manufacturers (there are 188 Linux versions at present), its application has expanded from the network to almost all IT fields, from database, enterprise Office, e-commerce software, network management, RAS (reliability, availability and serviceability) computing to computer aided design and manufacturing (CAD/CAM), film stunt simulation and so on. With the continuous introduction of new versions of Linux, the performance is also greatly improved. Many enterprises around the world have begun to use Linux operating platforms or servers to deal with huge data.

Misunderstanding three

Only suitable for small and medium-sized enterprises

There has always been a misunderstanding: since Linux is open source, its characteristic is that it is cheaper than operating systems such as Windows NT, which makes its application is limited to small companies. In fact, this is not the case. The networking ability of Linux is very strong, and its TCP/IP code is * * level. Linux provides full support for the current TCP/IP protocol and includes support for the next generation Internet protocol IPv6. The Linux kernel also includes IP firewall code, IP anti-counterfeiting, IP quality of service control and many security features. These features are comparable to those of high-end routing devices provided by companies such as Cisco. These application cases prove that Linux is absolutely malleable, has the ability to execute critical applications, and can meet the processing needs of high data load traffic (even the advanced supercomputing work).

Misunderstanding four

There is no profit in Linux market

Linux is free, so does that mean it won't be profitable in the Linux market? The answer is no. Linux vendors may not make a lot of money from issuing operating systems, but they can make a profit by developing on the Linux platform. For example, the profit of Linux server manufacturers lies in that the server is a combination of software and hardware, and its efficacy and value come from this combination, rather than independent software and hardware. And the hardware of the Linux server already contains a certain profit, and the free Linux is a condition for manufacturers to reduce costs. In addition, Linux manufacturers have a large profit margin in mobile phones and PDA products (a typical example of Linux embedded development and application).

Misunderstanding 5

Rely solely on price advantage

When users evaluate Linux servers, Windows NT servers, and Unix servers, there is no doubt about the price advantage of Linux. However, stability and reliability are the main reasons for users to use Linux. Machines running Linux can run for months at a time, providing complete memory protection, with each process running in its own virtual address space without damaging the address space used by other processes or kernels. Tasks and kernels are also isolated from each other, and even poorly behaved or poorly written programs can only destroy themselves. As a result, it is almost impossible for the corrupted process to crash the system. In addition, Linux system has good anti-virus and security performance, which is also an important reason for users to use it.

Linux becomes a substitute of Unix system on personal computer and inherits many advantages of Unix. However, the current performance has gradually begun to replace the Unix operating system to occupy the server market. However, from one aspect, we can see that Unix is gradually moving closer to Linux, and Unix manufacturers including IBM, Sun, HP and other Unix manufacturers have begun to support Linux. Open source code is the trend of the times, and Linux has a bright future. An The Free Standards Group association of the largest servers and Linux vendors in the industry has released the Linux standard they have worked hard to develop. These standards are developed to ensure that different versions of Linux work the same way.
