What types of isolated areas in Linux are implemented using namespaces?

In Linux, namespaces are used to isolate various system resources between processes. The main types of namespaces that implement isolated areas are:

• PID namespace — isolates process identifiers, allowing different namespaces to have processes with the same PID.
• Mount namespace — isolates mount points of file systems, allowing different processes to see different file systems.
• UTS namespace — isolates system identifiers such as hostname and domain name.
• IPC namespace — isolates inter-process communication (shared memory segments, message queues, and semaphores).
• Network namespace — isolates network interfaces, IP addresses, routing tables.
• User namespace — isolates user and group IDs, allowing processes to have different privileges in different namespaces.
• Cgroup namespace — isolates cgroup hierarchies.

These namespaces enable the creation of containers and other forms of isolation in Linux.
