- The functioning of UNIX operating system is handled in three levels. At the heart of UNIX is the kernel, which interact with actual hardware. Kernel is the fundamental part(core) of the OS. That resides in main memory at all times. On the outer crust are the application packages and user programs. The dilled layer is the shell which acts as a mediator that translates the commands given by the application programs in the outer later and conveys them to the kernel layer. The kernel then executes these commands using the inner hardware.

In order to legally be called a "Unix" system, operating systems must undergo a rigorous and expensive certification procedure. "Unix-like" refers to systems that have an architecture similar to Unix, but have not undergone certification.
Indefinite. It is dependent on the computer architecture and the version being used.
No. Linux is a free, open-source version of UNIX. Many of DOS's commands were based on UNIX commands, but the underlying operating system is much more powerful than DOS.
Both Windows and Unix based operating systems will continue to evolve with hardware. Currently, 64-bit architecture is becoming more common and will slowly replace 32-bit architecture. Given time, 128-bit architecture will likely replace 64-bit, and so on.
UUCP is the abbriviation of Unix to Unix copy. It is worldwide email system called UUCP or Unix to Unix copy.This email system was developed for the operating system called Unix.
No, but Linux is based on Unix since Linux is a Unix clone.
Unix work is performed by users of the unix system, for application and system programs, or anything that requires a Unix system.
Unix commands
A computer that runs Unix.
A Unix console is a CLI interface through which to control or monitor a Unix computer.
Unix configuration is the process of tailoring a freshly installed version of Unix to your particular environment. Each Unix system may do that differently.
