- 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.
What else can I help you with?
Which layer in unix architecture is programmable?
shell
What is the difference between Unix and Unix-like?
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.
What is the maximum size of a Process Address space in Unix or Linux?
Indefinite. It is dependent on the computer architecture and the version being used.
Is the architecture of Linux based on DOS?
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.
What do the letters UNIX stand for?
The letters "UNIX" do not stand for anything specific as an acronym; rather, it is a name derived from the earlier operating system Multics. The name "UNIX" was coined as a play on "Multics," indicating its simpler design. It reflects the system's focus on a multi-user environment, which was a key feature of its architecture.
What is a Unix clone?
A Unix clone is an operating system that is designed to be compatible with the original Unix operating system, typically by replicating its functionality, commands, and programming interfaces. These clones often aim to provide a similar user experience while being developed independently. Examples include Linux and BSD systems, which share core Unix-like features but differ in design, architecture, and licensing. Unix clones have significantly contributed to the proliferation of Unix-like systems in various computing environments.
Draw and the Explain the architecture of windows and unix?
Windows and UNIX have distinct architectures. Windows Architecture: It consists of a layered structure with a kernel at the core, managing hardware interactions, system calls, and user mode applications. Above the kernel are various subsystems, including the Windows API, which provides applications with the necessary services and functionalities. UNIX Architecture: UNIX follows a modular design, featuring a kernel that interfaces directly with hardware and manages system resources. User applications run in user mode, interacting with the kernel through system calls, while the shell provides a command-line interface for user interaction. Both architectures emphasize separation between user space and kernel space for stability and security.
What computer organization or architecture is likely to survive the most years?
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.
What is uucp?
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.
Is UNIX based on Linux?
No, but Linux is based on Unix since Linux is a Unix clone.
Who is Unix work performed by?
Unix work is performed by users of the unix system, for application and system programs, or anything that requires a Unix system.
What is a Unix Computer?
A computer that runs Unix.
