TAILIEUCHUNG - Lecture Operating system concepts (Sixth ed) - Module A: The FreeBSD system

Lecture Operating system concepts (Sixth ed) - Module A: The FreeBSD system. The following will be discussed in this chapter: history, design principles, programmer interface, user interface, process management, memory management, file system, I/O system, interprocess communication. | Module A The FreeBSD System History Design Principles Programmer Interface User Interface Process Management Memory Management File System I O System Interprocess Communication Operating System Concepts Silberschatz Galvin and Gagne 2002 History First developed in 1969 by Ken Thompson and Dennis Ritchie of the Research Group at Bell Laboratories incorporated features of other operating systems especially MULTICS. The third version was written in C which was developed at Bell Labs specifically to support UNIX. The most influential of the non-Bell Labs and non-AT T UNIX development groups University of California at Berkeley Berkeley Software Distributions . 4BSD UNIX resulted from DARPA funding to develop a standard UNIX system for government use. Developed for the VAX is one of the most influential versions and has been ported to many other platforms. Several standardization projects seek to consolidate the to UNIX. Operating System Concepts variant flavors of UNIX leading to one programming interface Silberschatz Galvin and Gagne 2002 History of UNIX Versions Operating System Concepts Silberschatz Galvin and Gagne 2002 Early Advantages of UNIX Written in a high-level language. Distributed in source form. Provided powerful operating-system primitives on an inexpensive platform. Small size modular clean design. i-K Operating System Concepts Silberschatz Galvin and Gagne 2002 UNIX Design Principles Designed to be a time-sharing system. Has a simple standard user interface shell that can be replaced. File system with multilevel tree-structured directories. Files are supported by the kernel as unstructured sequences of bytes. Supports multiple processes a process can easily create new processes. High priority given to making system interactive and providing facilities for program development. Operating System Concepts Silberschatz Galvin and Gagne 2002 Programmer Interface Like most computer systems UNIX consists of two separable parts .
