i am in need of differences between windows operating system,mac operating system,linux operating system,unix operating system
In a nutshell:
1. Windows: proprietary operating system loosely based on Digital's VMS and DOS. Runs on x86, amd64, and Itanium systems.
2. MacOS X: a proprietary Unix operating system with a custom, proprietary window manager and only runs on Apple-sourced hardware.
3. Linux: open-source Unix-like operating system that was initially written from scratch in 1991. Runs on almost any hardware out there, from tiny embedded computers to the biggest supercomputer on the planet.
4. Unix: a general term to describe operating systems that are loosely derived from a very popular operating system developed by AT&T in the 1960s or UC Berkeley in the 1970s and have some general characteristics in common. There are many operating systems based on Unix, some open-source (BSD UNIX) or proprietary (IBM's AIX.)
That's the differences in a nutshell. If you want more information, Wikipedia is your friend because we could write books on the topic.
OS of course. I had a look the other night, it sounds like interesting stuff you did. I've worked with people that were key players in the OpenVMS project and there is nothing quite so scary as somebody that really knows a system inside out.
Yeah - it's just a toy, but it is quite a challenge. I can't think of many more difficult projects. Debugging is a nightmare to start with and it can be quite hard getting information about the hardware. But it's a fun intellectual excercise which is what computers are all about for me; I must work a bit more on it sometime.
