groupware systems

We know that Unix and Linux systems are both open-source systems, but they are different in many aspects. As the system continues to improve, the two are also greatly different. So let's make a comparison for some special settings. Today, we will discuss the Ftp and telnet service configurations in Linux and Unix systems. Having worked on Unix

Article Title: achieve free switching between Windows and Linux 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. Using the techniques described in this article, we can automatically switch from one operating system to another on a dual-boot machine without any ma

Currently, this mode of wire and connection is widely used. Its network structure is tree and ring. Tree type, which is commonly used by most systems. The ring type has four cables for the control device. In addition, there is also a chain connection type, its P line is connected in series with various fire det
