Solution 1: A Daemon is a kind of program that keeps on running silently in the background. It is activated by the occurrence of a certain event or condition. It accommodates the service requests from other computers on a computer network and it is also responsible for responding to other programs and hardware activity.

Solution 2: /lib folder or the Lib directory contains kernel modules and shared library images that are helpful in performing the system booting and running commands in the root file system.

Solution 3: An absolute path refers to the same file location in a file system relative to the root directory, on the other hand, a relative path refers to a particular location in the file system that is relative to the current directory user is working on.

Solution 4: The init is a program that acts as the last process in the booting procedure of a Linux system. It is responsible for starting system processes during the booting procedure.

Solution 5: The chmod is the command that is used to change the permissions of a file or directory. In order to use it, the user has to mention the desired permission settings and the files that he/she may wish to modify.
