1. Server
1. Concept
As hardware, servers usually refer to computers that have high computing power and can be used by multiple users. There are many differences between a server and a PC. For example, a PC usually only serves one user at a time. The server is different from the host. The host is used by the user through the terminal, and the server is used by the client user through the network. Therefore, in addition to the terminal device, the network can be used to use the server computer, but the user can use the server after connecting online On the specific service.

CentOS is an enterprise-level Linux distribution based on the freely available source code provided by Red Hat Linux. Each version of CentOS will receive ten years of support (through security updates). New versions of CentOS are released approximately every two years, and each version of CentOS is updated regularly (about every six months) to support new hardware. In this way, a safe, low-maintenance, stable, highly predictable, and highly repeatable Linux environment is established. CentOS is the abbreviation of Community Enterprise Operating System.
