prevent data loss due to unexpected disk damage to the maximum extent. RAID 0 aims to speed up disk reading and does not provide any data backup and protection functions. We can select different raid applications based on the actual situation.

. Also, a network application can bind to the port it needs (such as the 53 port of BIND), but it cannot bind to other ports.The domain-type model means that each process running in the security domain and each resource (generic, directory, socket, and so on) has a "type" associated with it.On top of that, a series of rules are set up that lists all the actions that a domain can perform on each type.
