Interpreter Middleware Virtual machine Operating system Software quality. The function of the device driver is then to translate these operating system mandated function calls into device specific calls. In cooperation with the University of Minnesota, the Kronos and later the NOS operating systems were developed during the s, which supported simultaneous batch and timesharing use. The user interface is usually referred to as a shell and is essential if human interaction is to be supported. Archived from the original on 5 November This tutorial has been prepared for the computer science graduates to help them understand the basic to advanced concepts related to Operating System. Therefore, one can install and be running an insecure service, such as Telnet or FTP, and not have to be threatened by a security breach because the firewall would deny all traffic trying to connect to the service on that port.

The operating system must be capable of distinguishing between requests which should be allowed to be processed, and others which should not be processed. To solve this problem, operating systems essentially dictate how every type of device should be controlled. Most of the modern computer systems support graphical user interfaces GUIand often include them. Bic, Lubomur F. Chapter 1.

    A LECTURE NOTE ON CSC 322 OPERATING SYSTEM I BY DR. S. A. SODIYA 1 SECTION ONE 1.0 INTRODUCTION TO OPERATING SYSTEMS 1.1 DEFINITIONS OF OPERATING SYSTEMS An operating system (commonly abbreviated OS and O/S) is the infrastructure software component of a computer system; it is responsible for the management and coordination of activities and the sharing of the limited resources of the computer. An operating system is the set of programs that controls a computer. The operating system acts as a host for applications that are run on the machine. As a host, one of the purposes of an operating system is to handle the details of the operation of the hardware. This relieves application programs from having to manage these details and makes it easier to write applications. Operating Systems can be viewed from two points of views: Resource manager and Extended machines. From Resource manager point of view, Operating Systems manage the different parts of the system efficiently and from extended machines point of view, Operating Systems provide a virtual machine to users that is more convenient to use. 1.2 HISTORICAL DEVELOPMENT OF OPERATING SYSTEMS Historically operating systems have been tightly related to the computer architecture, it is good idea to study the history of operating systems from the architecture of the computers on which they run. Operating systems have evolved through a number of distinct phases or generations which corresponds roughly to the decades. The 1940's - First Generation The earliest electronic digital computers had no operating systems. Machines of the time were so primitive that programs were often entered one bit at a time on rows of mechanical switches (plug boards).

The operating system acts as a host for applications that are run on the machine. Program execution: The operating system acts as an interface between an application and the hardware. Interrupts: InterruptsWWW.BSSVE.IN are central to operating systems as they provide an efficient way for the operating system to interact and react to its environment. Supervisor mode: Modern CPUs support something called dual mode operation. CPUs with this capability use two modes: protected mode and supervisor mode, which allow certain CPU functions to be controlled and affected only by the operating system kernel. Here, protected mode does not refer specifically to the 80286 (Intel's x86 16-bit microprocessor) CPU feature, although its protected mode is very similar to it. Memory management: Among other things, a multiprogramming operating system kernel must be responsible for managing all system memory which is currently in use by programs. www.bsscommunitycollege.in www.bssnewgeneration.in www.bsslifeskillscollege.in 2 www.onlineeducation.bharatsevaksamaj.net www.bssskillmission.in Key Points: 1.

    IJMEIT// Vol.04 Issue 08//August//Page No:1729-1735//ISSN-2348-196x 2016 Investigation into Gang scheduling by integration of Cache in Multi core processors Authors Rupali1, Shailja Kumari2 1Research Scholar, Department of CSA, CDLU Sirsa 2Assistant Professor, Department of CSA, CDLU Sirsa, Email- [email protected] ABSTRACT Objective of research is increase efficiency of scheduling dependent task using enhanced multithreading. gang scheduling of parallel implicit-deadline periodic task systems upon identical multiprocessor platforms is considered. In this scheduling problem, parallel tasks use several processors simultaneously. first algorithm is based on linear programming & is first one to be proved optimal for considered gang scheduling problem. Furthermore, it runs in polynomial time for a fixed number m of processors & an efficient implementation is fully detailed. second algorithm is an approximation algorithm based on a fixed- priority rule that is competitive under resource augmentation analysis in order to compute an optimal schedule pattern. Precisely, its speedup factor is bounded by (2−1/m). In computer architecture, multithreading is ability of a central processing unit (CPU) or a single core within a multi-core processor to execute multiple processes or threads concurrently, appropriately supported by operating system. This approach differs from multiprocessing, as with multithreading processes & threads have to share resources of a single or multiple cores: computing units, CPU caches, & translation lookaside buffer (TLB). Multiprocessing systems include multiple complete processing units, multithreading aims to increase utilization of a single core by using thread-level as well as instruction-level parallelism. Keywords: TLP, Response Time, Latency, throughput, multithreading, Scheduling threaded processor would switch execution to 1.

  • Research Methodologies for Multitasking Studies
    329 Chapter 17 Research Methodologies for Multitasking Studies Lin Lin University of North Texas, USA Patricia Cranton University of New Brunswick, Canada Jennifer Lee University of North Texas, USA ABSTRACT The research on multitasking is scattered across disciplines, and the definitions of multitasking vary according to the discipline. As a result, the research is not coherent nor consistent in the approaches taken to understanding this phenomenon. In this chapter, the authors review studies on multitasking in different disciplines with a focus on the research methodologies used. The three main research paradigms (empirical-analytical, interpretive, and critical) are used as a framework to understand the nature of the research. The strengths and weaknesses of the research in each of the paradigms are examined, and suggestions are made for utilizing different research methodologies to bring clarity to the research in this field. Such an endeavour will help to build interdisciplinary and multidisciplinary research and help guide future research and theory building. INTRODUCTION all times of the day in millions of households be- came an all too familiar sight. Families ate, played, Research on multitasking has a long history.

Personal computers: - This is the most common type found in homes, schools, Business offices etc., It is the most common type of desk top computers with processing and storage units along with various input and output devices. 2. Note book computers: - These are compact and portable versions of PC 3. Work stations: - These have high resolution input/output (I/O) graphics capability, but with same dimensions as that of desktop computer. These are used in engineering applications of interactive design work. 4. Enterprise systems: - These are used for business data processing in medium to large corporations that require much more computing power and storage capacity than work stations. Internet associated with servers have become a dominant worldwide source of all types of information. 5. Super computers: - These are used for large scale numerical calculations required in the applications like weather forecasting etc., 1.2 Functional unit A computer consists of five functionally independent main parts input, memory, arithmetic logic unit (ALU), output and control unit.
