The Linux System The Linux System History History Linux is a modem, free operating system based on UNIX standards. Design Principles First developed as a small but self-contained kernel in Kernel Modules 1991 by Linus Torvalds, with the major design goal of Process Management UNIX compatibility. Scheduling Its history has been one of collaboration by many users Memory Management from all around the world, corresponding almost File Systems exclusively over the Internet. Input and Output It has been designed to run efficiently and reliably on Interprocess Communication common PC hardware, but also runs on a variety of other platforms. Network Structure The core Linux operating system kernel is entirely Security original, but it can run much existing free UNIX software, resulting in an entire UNIX-compatible operating system free from proprietary code.Operating System Concepts 20.1 Silberschatz, Galvin and Gagne ©2002 Operating System Concepts 20.2 Silberschatz, Galvin and Gagne ©2002 The Linux Kernel Linux 2.0 Version 0.01 (May 1991) had no networking, ran only on 80386-compatible Intel processors and on PC hardware, Released in June 1996, 2.0 added two major new had extremely limited device-drive support, and capabilities: supported only the Minix file system. Support for multiple architectures, including a fully 64-bit native Alpha port. Linux 1.0 (March 1994) included these new features: Support for multiprocessor architectures Support for UNIX’s standard TCP/IP networking protocols BSD-compatible socket interface for networking Other new features included: programming Improved memory-management code Device-driver support for running IP over an Ethernet Improved TCP/IP performance Enhanced file system Support for internal kernel threads, for handling Support for a range of SCSI controllers for dependencies between loadable modules, and for automatic high-performance disk access loading of modules on demand. Extra hardware support Standardized configuration interface Version 1.2 (March 1995) was the final PC-only Linux Available for Motorola 68000-series processors, Sun kernel. Sparc systems, and for PC and PowerMac systems.Operating System Concepts 20.3 Silberschatz, Galvin and Gagne ©2002 Operating System Concepts 20.4 Silberschatz, Galvin and Gagne ©2002 The Linux ...
