A Comprehensive Study of Kernel (Issues and Concepts) in Different Operating Systems
Asian Journal of Research in Computer Science, 2021
Various operating systems (OS) with numerous functions and features have appeared over time. As a result, they know how each OS has been implemented guides users' decisions on configuring the OS on their machines. Consequently, a comparative study of different operating systems is needed to provide specifics on the same and variance in novel types of OS to address their flaws. This paper's center of attention is the visual operating system based on the OS features and their limitations and strengths by contrasting iOS, Android, Mac, Windows, and Linux operating systems. Linux, Android, and Windows 10 are more stable, more compatible, and more reliable operating systems. Linux, Android, and Windows are popular enough to become user-friendly, unlike other OSs, and make more application programs. The firewalls in Mac OS X and Windows 10 are built-in. The most popular platforms are Android and Windows, specifically the novelist versions. It is because they are low-cost, dependable, compatible, safe, and easy to use. Furthermore, modern developments in issues resulting from the advent of emerging technology and the growth of the cell phone introduced many features such as high-speed processors, massive memory, multitasking, high-resolution displays, functional telecommunication hardware, and so on. This review thesis is presented through two distinct perspectives: detailing several concerns related to the types of kernels and merits used and evaluating how novel technologies are evaluated, and assessing underperformance.
Micro kernel construction and architecture
Modular architecture based on a micro kernel are suitable platform for the design and implementation of operating systems. Prototype system using micro kernel architecture are achieving the levels of functionality and performance expected and required of commercial products. This paper describes the architecture and construction of mach microkernel,its use to support imlemntaions of other operating systems and the status of these efforts. Performance and flexibility of micro kernel is also analysed in the following paper.
On the development of a distributed operating system kernel for real-time applications
Annual Review in Automatic Programming, 1981
The operating system kernel of a multiprocessor system based on 16 bit microcomputers is described. The multiprocessor system constitutes a node of a local computer network dedicated to the control of continuous or discontinuous industrial processes. The kernel makes available a virtual machine where processes allocatedon dif ferent processors are executed in parallel, while processes which reside on the same processor are executed in a multitasking environment. The processes can cooperate by means of synchronization and message passing primitives; furthermore they can interact by means of short-term scheduling primitives which perform the creation, destruction, activation and termination of a process. The interprocessor communication mechanisms allow the primitives to make all the process interactions transparent to the physical allocation of the interacting processes. The system has been completely implemented in the PASCAL language, excepting only few functions of the lowest level, coded in the assembler language. The distributed kernel has been developed and tested on a conventional machine (a DEC PDP11/34 computer under RSXll-M Operating System). The processes allocated on the same processor have been implemented as a sil gle RSXll task, and interprocessor communications have been simulated by means of intertask system primitives.

The paper compares core kernel architecture and functionality of four modern operating systems. The subsystems examined are process / thread architecture, scheduling and interrupt handling. Linux, Solaris and FreeBSD have a lot of similarities, owning Unix roots, but also have some notable differences. However, Windows is significantly different, being a radical non-Unix design. The paper compares some aspects of the Unix-like approaches of Linux/Solaris/FreeBSD with Windows, emphasizing the consequences of their different design decisions, and presents some comparative performance results, using Java benchmarks.
Chapter 1: Operating System Models 2 Operating System Models 2.1 Introduction
Over the past several years, a number of trends affecting operating system design are witnessed and foremost among them is a move towards modularity. Operating systems such as Microsofts Windows, IBMs OS/2, C-DACs PARAS and others are splintered into discrete components, each having a small, well defined interface, and each communicating with others via inter-task message interface. The lowest level is the microkernel, which provides only essential OS services, such as context switching. Windows NT, for example, also includes a hardware abstraction layer (HAL) beneath its microkernel which enables the rest of the OS to perform irrespective of the processor underneath. This high level of OS portability is a primary driving force behind the modular, microkernel-based push.
Recent Trends in Operating Systems and their Applicability to
In this paper we consider recent trends in operating systems and discuss their applicability to high performance computing systems. In particular, we will consider the relationship between lightweight kernels, hypervisors, microkernels, modular kernels, and approaches to building systems with a single system image. We then describe how the Catamount lightweight kernel can be extended to support the Xen hypervisor API. This will, in turn, support use of Linux on the compute nodes of a large scale parallel system while minimizing the effort needed to support both, a lightweight OS and a full-featured OS.
ROAD MAP FOR PART ONE Chapter 1 Computer System Overview Chapter 2 Operating System Overview
An operating system mediates among application programs, utilities, and users, on the one hand, and the computer system hardware on the other. To appreciate the functionality of the operating system and the design issues involved, one must have some appreciation for computer organization and architecture. Chapter 1 provides a brief survey of the processor, memory, and Input/Output (I/O) elements of a computer system. The topic of operating system (OS) design covers a huge territory, and it is easy to get lost in the details and lose the context of a discussion of a particular issue. Chapter 2 provides an overview to which the reader can return at any point in the book for context. We begin with a statement of the objectives and functions of an operating system. Then some historically important systems and OS functions are described. This discussion allows us to present some fundamental OS design principles in a simple environment so that the relationship among various OS functions is clear. The chapter next highlights important characteristics of modern operating systems. Throughout the book, as various topics are discussed, it is necessary to talk about both fundamental, well-established principles as well as more recent innovations in OS design. The discussion in this chapter alerts the reader to this blend of established and recent design approaches that must be addressed. Finally, we present an overview of Windows, UNIX, and Linux; this discussion establishes the general architecture of these systems, providing context for the detailed discussions to follow.

This paper presents a comparative survey of three well known operating systems which are Windows, Linux, and Macintosh. The basic criteria for studying them are mostly focusing on the fundamental memory and file management, architecture, security, versatility and other topics. These topics are being compared in this paper. This research study gives us an overview of the main topics and on the various similarities and differences in the basic use of operating systems. Every operating system has its own set of differences in the composition and structure of the operating system and this study focuses on the underlying strengths and weaknesses of each operating system.
