What is the difference between sudo su- and sudo -i ?
here is an alternative to Docker called Podman. The primary differ- ence between the two tools is that Docker requires a server to be running when using containers, while Podman does not.

Fortunately for the kernel, there is help. Modern CPUs include a memory management unit (MMU) that enables a memory access scheme called virtual memory. When using virtual memory, a process does not directly access the memory by its physical location in the hardware. Instead, the kernel sets up each process to act as if it had an entire machine to itself. When the pro- cess accesses some of its memory, the MMU intercepts the access and uses a memory address map to translate the memory location from the process point of view into an actual physical memory location in the machine. The kernel must still initialize and continuously maintain and alter this mem- ory address map. For example, during a context switch, the kernel has to change the map from the outgoing process to the incoming process. The implementation of a memory address map is called a page table.

The cd command is a shell built-in. It wouldn’t work as a separate program because if it were to run as a subprocess, it could not (normally) change its parent’s current working directory. This may not seem a particularly important distinction at the moment, but there are times when knowing this fact can clear up confusion.
