After studying this lesson they will be familiar with: 1. What is an operating system? 2. Important functions performed by an operating system. 3. Different types of operating systems. 1. 1 INTRODUCTION Operating system (OS) is a program or set of programs, which acts as an interface between a user of the computer & the computer hardware. The main purpose of an OS is to provide an environment in which we can execute programs. The main goals of the OS are (i) To make the computer system convenient to use, (ii) To make the use of computer hardware in efficient way. Operating System is system software, which may be viewed as collection of software consisting of procedures for operating the computer & providing an environment for execution of programs. It’s an interface between user & computer. So an OS makes everything in the computer to work together smoothly & efficiently.

The UNIX Time- Sharing System
1. Introduction There have been three versions of UNIX. The earliest version (circa 1969–70) ran on the Digital Equipment Cor- poration PDP-7 and -9 computers. The second version ran on the unprotected PDP-11/20 computer. This paper describes only the PDP-11/40 and /45 [l] system since it is The UNIX Time- more modern and many of the differences between it and older UNIX systems result from redesign of features found Sharing System to be deficient or lacking. Since PDP-11 UNIX became operational in February Dennis M. Ritchie and Ken Thompson 1971, about 40 installations have been put into service; they Bell Laboratories are generally smaller than the system described here. Most of them are engaged in applications such as the preparation and formatting of patent applications and other textual material, the collection and processing of trouble data from various switching machines within the Bell System, and recording and checking telephone service orders. Our own installation is used mainly for research in operating sys- tems, languages, computer networks, and other topics in computer science, and also for document preparation.

A Requirements Modeling Language for the Component Behavior of Cyber Physical Robotics Systems
A Requirements Modeling Language for the Component Behavior of Cyber Physical Robotics Systems Jan Oliver Ringert, Bernhard Rumpe, and Andreas Wortmann RWTH Aachen University, Software Engineering, Aachen, Germany {ringert,rumpe,wortmann}@se-rwth.de Abstract. Software development for robotics applications is a sophisticated en- deavor as robots are inherently complex. Explicit modeling of the architecture and behavior of robotics application yields many advantages to cope with this complexity by identifying and separating logically and physically independent components and by hierarchically structuring the system under development. On top of component and connector models we propose modeling the requirements on the behavior of robotics software components using I/O! automata [29]. This approach facilitates early simulation of requirements model, allows to subject these to formal analysis and to generate the software from them. In this paper, we introduce an extension of the architecture description language MontiArc to model the requirements on components with I/O! automata, which are defined in the spirit of Martin Glinz’ Statecharts for requirements modeling [10]. We fur- thermore present a case study based on a robotics application generated for the Lego NXT robotic platform. “In der Robotik dachte man vor 30 Jahren, dass man heute alles perfekt beherrschen würde”, Martin Glinz [38] 1 Introduction Robotics is a field of Cyber-Physical Systems (CPS) which yields complex challenges due to the variety of robots, their forms of use and the overwhelming complexity of the possible environments they have to operate in. Software development for robotics ap- plications is still at least as complex as it was 30 years ago: even a simple robot requires the integration of multiple distributed software components. -
UNIX Operating System Porting Experiences*
UNIX Operating System Porting Experiences* D. E. BODENSTAB, T. F. HOUGHTON, K. A. KELLEMAN, G. RONKIN, and E. P. SCHAN ABSTRACT One of the reasons for the dramatic growth in popularity of the UNIX(TM) operating sys- tem is the portability of both the operating system and its associated user-level programs. This paper highlights the portability of the UNIX operating system, presents some gen- eral porting considerations, and shows how some of the ideas were used in actual UNIX operating system porting efforts. Discussions of the efforts associated with porting the UNIX operating system to an Intel(TM) 8086-based system, two UNIVAC(TM) 1100 Series processors, and the AT&T 3B20S and 3B5 minicomputers are presented. I. INTRODUCTION One of the reasons for the dramatic growth in popularity of the UNIX [1, 2] operating system is the high degree of portability exhibited by the operating system and its associated user-level programs. Although developed in 1969 on a Digital Equipment Corporation PDP7(TM), the UNIX operating system has since been ported to a number of processors varying in size from 16-bit microprocessors to 32-bit main- frames. This high degree of portability has made the UNIX operating system a candidate to meet the diverse computing needs of the office and computing center environments. This paper highlights some of the porting issues associated with porting the UNIX operating system to a variety of processors. The bulk of the paper discusses issues associated with porting the UNIX operat- ing system kernel. User-level porting issues are not discussed in detail. -

Find Your Product Key To install the operating system from scratch or upgrade to a new version, you need to have a Windows 10 product key or a product key for the version of the operating system you want to install. This field is for validation purposes and should be left unchanged. What truly sets this card apart, however, is the notably quiet fan that cuts down on noise. An operating system provides a uniform set of screws, lumber and any other material you need. And that's really important, because here's another thing: Remember how we were talking about the operating system only being able to concentrate on one thing at a time? This includes selecting locations and privacy settings. This card supports two-plus DVI monitors without needing extra hardware or adapters. Price : Free with Apple Devices.
