WINDOWS VS MAC OS X VS LINUX CODE

While the macOS kernel combines the capabilities of a microkernel with Mach and a monolithic kernel like BSD, Linux is just a monolithic kernel. In several debates this also opened the question of the fact that a hybrid kernel is more stable if one of its parts stops, the other can start it again. Unlike Linux, this kernel is split into what they call the hybrid kernel, allowing one part of it to stop for maintenance, while another continues to work. Map of MacOS: the heart of everything is called Darwin and within it, we have separate system utilities and the XNU kernel, which is composed in parts by the Mach kernel and by the BSD kernel. The Mach part is responsible for low-level work such as multitasking, protected memory, virtual memory management, kernel debugging support, and console I/O.

The following year, Orest Zborowski ported the X Windows System to Linux, giving it the ability to support a graphical user interface. Soon, he was receiving code and resource suggestions Worldwide. Linus posted the code for his new kernel on the web in August 1991. Originally, the kernel was written according to the specifications of LinusРІР‚в„ўs computer because he wanted to take advantage of his new 80386 processor.

Instead, it was created in 1991 by computer student Linus Torvalds. Unlike the macOSР’В kernel, Linux was not created as part of a commercial enterprise. As part of the deal, Steve JobsР’В returned to Apple and NeXTSTEP became the foundation of macOS and iOS. In 1997, Apple bought NeXT for $429 million.

Meanwhile, Apple tried unsuccessfully to update its operating system on several occasions, even partnering with IBM. NeXT has never become a financial success, in part due to JobsРІР‚в„ўs habit of spending money as if he were still at Apple.
