what are kernel and shell and in which language i can make it and how long will it take to make it?

The kernel is the main part of the operating system.  It handles scheduling, memory management, hardware, etc.  The shell is an interface to the computer.  The command line is an example of a text-based shell, and Windows explorer is a graphical shell.  The shell's job is to run programs.  \n\nI made a shell in an operating systems course.  I chose to do it in Python, and others did it in C or C++.  You can use any language, even assembly.  It was a 2 week project and requires knowledge of system calls like fork, dup, etc.\n\nThe kernel isn't actually that big.  The linux kernel can be downloaded as a 30MB compressed file, but it includes assembly code for several architectures like x86, Mac, and even some rare and exotic machines.  Linus Torvalds created his own version of the Minix operating system as a student, but creating a kernel is a significant project that could take months or years with a small team of programmers.

On what OS?\nWindows: get Daemon Tools (www.daemon-tools.cc) (it's an image file)\nLinux: (it's a binary installation package), just open a console and write sh /.bin [par] (after sh is the path to the file and [par] rep the parameters that can be added afterwards, depending on the software!

The kernel\n\nThe kernel is the hub of the operating system: it allocates time and memory to programs and handles the filestore and communications in response to system calls. \n\nThe shell\n\nThe shell acts as an interface between the user and the kernel. When a user logs in, the login program checks the username and password, and then starts another program called the shell. The shell is a command line interpreter (CLI). It interprets the commands the user types in and arranges for them to be carried out. The commands are themselves programs: when they terminate, the shell gives the user another prompt.

If your answer is Windows, you're plain wrong. It's ITRON, a Japanese real-time OS kernel that can be customized for any small-scale embedded systems. According to LinuxInsider.com, it is used by more than 3 billion microprocessors found in mobile phones, digital cameras, CD players and many other electronic devices including even satellites.\n\nITRON emerged as an ambitious Japanese initiative known as The Real-time Operating system Nucleus (TRON). Launched in 1984, TRON was designed to replace disparate computer systems with a unified, open architecture for a "total computer environment."\nIts ultimate goal was to create "highly functionally distributed systems" in which all system components are connected to a real-time network. Professor Ken Sakamura, spiritual father of TRON, conceived the project as a social infrastructure akin to the electrical power grid or water supply system.\nITRON, the first in a series of open-source specifications for the TRON architecture, answered a pressing need for Japan's electronics firms, which traditionally have written their own software for embedded systems, a time-consuming and cumbersome process that often results in a plethora of different and incompatible systems.\nITRON has been followed by several other specifications -- among them Business TRON (BTRON), a multilingual, ubiquitous computing environment with a programmable GUI, and Communications and Central TRON (CTRON), a real-time, multitasking operating system akin to Unix.\nIn the United States, ITRON has a competitor, RTLinux, the real-time version of Linux developed by FSMLabs, Inc.\n\n[But] Steven Searle, who worked on developing TRON's multilingual environment, argues that ITRON has several advantages over real-time versions of Linux. "TRON is an RTOS; Linux isn't," Searle told LinuxInsider, adding that ITRON has a smaller footprint and superior real-time performance.\n"RTLinux switches tasks in milliseconds, while ITRON switches tasks in microseconds," he said. "RTLinux' footprint is measured in megabytes; ITRON is measured in kilobytes."\nSo, what's the future for this market? It's definitively open-source.\n\nThe T-Engine Forum, an offshoot of the TRON project with more than 250 member companies, has been working to create a standardized development environment for embedded applications based on ITRON.\n[And] MontaVista Software is actually helping to create a non-native kernel extension of TRON called T-Linux -- an environment for running middleware. T-Engine and Linux will form a base for developing application software that will include the eTRON chip, an encryption device that offers secure data transfer across wireless networks and the Internet.\nThis alliance between TRON and Linux could put more pressure on vendors of proprietary embedded software. Proprietary software is costly -- vendors usually charge royalties for each microprocessor running the software -- and licensing terms are often restrictive. Moreover, nearly all of the giants in the consumer electronics industry are rallying around open-source solutions.\nSource: Jan Krikke, LinuxInsider.com, October 15, 2003 \n\n\nWhat is the world's most widely used operating system?

First you will need to select a flavor of Linux to run I suggest red hat or a redhat derivative for a newbie.  You can download these @ http://www.linux.org/dist/index.html.  This will show you how to download and install.

you are using a pc will mac os run on a pc or do you have to run on a mac\n\nsorry add to answer\n\nyes you could do it but the amount of changes needed would be vast i would say if you are looking for a good solid OP i would use linux redhat or mandrak

There are a lot of good GNU/Linux distributions, depends what you want to do. if you want to your desktop, try Mandryba, Lycorix, Ubuntu (KUbuntu, Edubuntu), Gentoo... are the most frindly and easy to install.

If you are knowledge in Linux, Gentoo will be good choice. Otherwise, Windows

Most flavours have "live disc" available which allow you to run and experiment without having to install (ie, booting from disc). Have a play with a few and see which suits you best. The only 'nix version I ever really liked was SUSE, but have had to stick with Windows in the end - couldn't do my job on Linux ...too many software limitations

linux is the freakin best, but it is far from user friendly.\nget a mac.\nvery fast, friendly, and secure.
