Which command installs application files onto a computer?

The command that installs application files onto a computer is "make install." This command is typically used in the process of building software from source code. After the source code has been compiled using the "make" command, "make install" is employed to copy the compiled binaries, libraries, and other necessary files to their appropriate directories in the system, such as /usr/bin for executable files, or /usr/lib for libraries. This ensures that the installed application can be accessed and executed by users on the system.

The use of "make install" signifies that the installation follows the compilation process, linking all compiled components and setting them up properly in the filesystem. This is a common approach in Unix-like operating systems for managing software installation from source code, making it essential knowledge for anyone preparing for the CompTIA Linux+ certification.
