What are legacy systems (Legacy system)? According to Wikipedia, legacy systems are an old method, an old technology, an old computer system, or an application [1]. This definition does not, in fact, reveal the nature of the legacy system. I think the legacy system is first and foremost a software system that is still running and using, but has stepped into the software lifecycle aging period. It fits the s

Today, companies are highly dependent on computer networks. In fact, they can hardly run effectively without high-tech electronic devices. Once purchased, the reliable operation of these electronic devices becomes crucial. System faults will not only lead to loss of business opportunities or reduction of production efficiency, but also cause a rapid decline in user confidence in the system. As a result, the user either tries to avoid the network and thus cannot gain all commercial advantages, or

No one can tell you what operating systems are best for your organization or yourself better than you can. Here are some tips for selecting the right OS for the right job.

PrefaceConfiguring and compiling an appropriate GNU Toolchain is relatively complex and requires fine-grained operations, including the dependencies you need on different repositories, their respective tasks, and a better understanding of the different versions of the repositories, which is a tedious task.2. Some terms and names that need to be understood before making1) Build: The compilation system that you use to compile your toolchain.2) Host: The cross-compiler tool chain runs on the hos

Recommend a book on embedded entry: Embedded system design (Chongqing University Press, author Pens). I recently also took a good look at some of the content, combined with our previous classes to learn some embedded knowledge and the previous operating system and the composition of the principle, with the following summary, is a time for this book to learn the knowledge of a summary, but also the knowledge of the previous study a review. Personally, the learning of embedded

the CD-ROM installation of the Linux operating system, you need to install, change the CD to boot as the first boot, the system is installed, and then the hard disk boot back to the first boot. However, installing the Linux operating system in a virtual machine eliminates the need to change the BIOS startup settings, and the virtual opportunities are automatically identified and adjusted. So we don't have to take this step here. 4. After the virtual machine is turned on, the disc settings of t

A file system is a mechanism for organizing data and metadata on a storage device. The Linux file system interface is implemented as a layered architecture that separates the user interface layer, the file system implementation, and the driver of the operating storage device. Another way to look at a file system is to think of it as a protocol. Network protocols, such as IP, specify the meaning of the data stream that is transmitted over the Internet, and the file system gives the meaning of the
