Operating Systems And Computer Architecture Eng Hector M Lugo Cordero The core linux operating system kernel is entirely original, but it can run much existing free unix software, resulting in an entire unix compatible operating system free from proprietary code. The aim of this chapter is to outline the fundamentals of computer architecture that are needed to understand the working of an operating system. this chapter does not aim to teach the student computer architecture in its entirety.
Lecture04 Operating System Architecture Pdf Kernel Operating Unlike many linux books that are written for system administrators or software professionals who develop linux systems or applications, this book takes a unique approach and discusses the topics at a level that is appropriate for undergraduate students who are learning linux.”. Linux is a multiuser, multitasking system with a full set of unix compatible tools. its file system adheres to traditional unix semantics, and it fully implements the standard unix networking model. main design goals are speed, efficiency, and standardization. Operating systems evolve over time, but that evolution is frequently in terms of their architecture: how they structure functionality relative to protection boundaries. Abstract linux is a unix like operating system for intel 386 486 pentium based ibm pcs and compati bles. the kernel of this operating system was written from scratch by linus torvalds and, although copyright by the author, may be freely distributed.

The linux world is vast and diverse, with numerous distributions based on different core systems. red hat, debian, and suse are three of the most prominent and influential distributions, each with its own unique lineage and family tree. Operating system & hardware interaction major operating system families evolution of operating system operating system architecture models user space vs kernel space system calls, signals, h w interrupts & traps why linux?. Linux technology has become one of the cornerstones of modern computing, widely adopted in diverse fields ranging from embedded systems to cloud computing. this paper aims to explore the fundamental concepts of linux, its architecture, and the evolution of this open source operating system. Another book real time linux, device drivers a modern computer system is built from many parts: cpu – 32 64 bit, big little endian, risc cisc, harvard, von neumann., etc. buses – hypertransport, pcie, pci x, etc. memory – caches (i ii iii), ram, vram (gart), etc. peripherals – hard disks (sata, scsi, ssd),dvd, graphics, sound, wifi, etc.
