It is more difficult to develop applications, only applicable to the network, etc. These evaluations of Linux are only the opinions of some people who do not know Linux. Once you really know Linux, you will be conquered by the charm of Linux...
Misunderstanding 1
Difficulty developing applications
There was some truth to this argument three years ago. In the past, developing applications for Linux using traditional tools was difficult. Traditional GCC and Emacs are difficult to learn and not as efficient as enterprise developers need. And now Linux has a full-featured, visual, fast programming tool - Kylix, which completely solves this problem. Kylix uses 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, making it difficult to count Win32 commercial applications are ported to the Linux platform.
Misunderstanding 2
network only
Linux is almost synonymous with the web, and there is a huge army of Linux supporters on the web. With the joining of more and more Linux manufacturers (currently there are 188 Linux versions), its application has expanded from the network to almost all IT fields, ranging from databases, enterprise-level Office, e-commerce software, network management, RAS ( reliability, availability, and serviceability) calculations, to computer-aided design and manufacturing (CAD/CAM), movie special effects simulations, and more. With the continuous introduction of new versions of Linux, the performance is also greatly improved. Many companies around the world have begun to use Linux operating platforms or servers to process huge amounts of data.
Misunderstanding 3
For small and medium businesses only
There has always been such a misunderstanding: since Linux is open source, its biggest feature is that it is cheaper than operating systems such as Windows NT, which makes its application limited to small companies. This is not the case, the networking capability of Linux is very powerful, and its TCP/IP code is the most advanced. 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 equipment offered by companies such as Cisco. These use cases prove that Linux is absolutely scalable, capable of executing critical applications and meeting the processing demands of high data traffic (even the most advanced supercomputing jobs).
Misunderstanding 4
The Linux market is unprofitable
Linux is free, so doesn't that mean it won't be profitable in the Linux market? The answer is no. Linux vendors may not get a lot of profit from distributing operating systems, but they can make profits by developing on the Linux platform. For example, the profit of Linux server manufacturers lies in the fact 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. Moreover, the hardware of Linux servers already contains a certain profit, and the free Linux is a condition for reducing costs for manufacturers. In addition, Linux manufacturers have huge profit margins in mobile phones and PDA products (typical examples of Linux embedded development applications).
Misunderstanding 5
Only rely on price advantage
When users evaluate Linux servers, Windows NT servers and Unix servers, the price advantage of Linux is unquestionable. However, stability and reliability are the main reasons for users to use Linux. A machine running Linux can run for months at a time, providing full memory protection, with each process running in its own virtual address space and without corrupting the address space used by other processes or the kernel. Tasks are also isolated from the kernel, and even poorly behaved or poorly written programs can only destroy themselves. Therefore, it is almost impossible for a corrupted process to crash the system. In addition, the Linux system has good antivirus and security performance, which is also an important reason for users to use it.
Linux has become a substitute for Unix system on personal computers, inheriting many advantages of Unix. But the current performance has begun to gradually 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, and HP have begun to support Linux. Open source is the general trend, and Linux has a bright future. The Free Standards Group, a consortium of the industry's largest server and Linux vendors, has published their hard-working Linux standards. These standards are made to ensure that different versions of Linux work the same.
