It is designed and developed in order to support personal computer system or workstation of the organization by connecting to a local area network known as LAN. Network operating system allows the organization to share files and documents and access printer among numerous computer system connected within a network either on a private network or local area network. Computing and system development helps to establish diverse range of skills in relation to modern computing and networking technologies. The concept of computing and system development helps to give an in- depth knowledge and understanding about different aspects of networking and computing discipline. The objective of the study is to provide detailed information about computing and system development. Based on given case scenario, requirements of network operating system of the company will be identified and depending on that appropriate network operating system will be recommended. 1 LO1: Evaluation of Network operating System Principles 1.1 Evaluations of various types of NOS 1.1.1 Network services requirements Based on the case scenario, the company for its new branch in Manchester will be required ● Infrastructure services: it covers the necessities requirements of the company to be present online. It includes VPN configuration, service design and installation, network design and configuration, window as well as exchange server configurations (Simsarian, 2018). ● Wireless networks: it enables the company to use internet over a private network or local area network. Robust as well as reliable wireless network servers will be designed. ● Managed support: the support team comprising of IT professional and technician will be developed to provide system support and help manage computer systems. ● Data Backup and disaster recovery: data backup services will be implemented to keep the company data secure. Besides, data recovery plan will be designed to eradicate business failure issues in case of worst happen (Huang, 2017). 1.1.2 Appropriate network for the case scenario After assessing the needs of the company new venture and seeking into its future requirements of computing and networking system, it is critical to develop a virtual environment to support remote computer system, data security, and print services as well as print server. Along with that, network management tools, firewall protection for network project, antivirus software will be employed to eradicate the threats of system failure and redundancy(Shin et al. 2014). In Figure 1 such principles of operating system have been reflected. However, all of those are not interdependent; but somehow, an efficient networking system should include all of these principles. In the following picture this aspect has been included. Figure 1: Network operating system principles, (Source: Santamaria, 2016) In figure 1, In the above picture,anefficient networking system has been reflected. On the other hands, it has also instructed the relationship between each other. It is important to understand the relationship as well as applications of network communication. Network managementand firewall protection (Santamaria, 2016). There are many vendors available in the market those are engaged to provide a support of a network centric approach. It is the service standard of the vendors that establish the efficiency of networking in a small organization as well as a group of network. Such vendors are discussed below as per availability and features. Stratum: Stratum provides open advanced while box switches along with advanced technology of SDN interfaces. Switch networking solutions are mainly supported by faster communication and high speed data transfer. On the other hand, it also provides software oriented programming as well as featured aspects of security. Cumulus Network: Cumulus networking is an open ended network and it is framed on Linux. Having an open channel networking, the security measure of this vendor is restricted. It connects the ease of OCP following updown 2. Big switch light: Big Switch light is based on open network and having some features of Stratum. It is built on Linux and there are several implications of SDN. The open networking channel establishes faster data center approach having restricted security standards. Linux Network: Having flash memory and bare channels of switching have made this vendor easier to use. On the other hand, Linux establishes opem computing project and open flow centric operations. 1.1.3 Comparison and evaluation of various NOS Technical windows Linux Mac Osx Characteristics Security Window operating system is Linux has less level of Security Vulnerability highly vulnerable to cyber- vulnerability in and threats on Mac attacks.

  • Chapter 1. Origins of Mac OS X
    1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years.

  • 1. Introduction
    Network Operating Systems Partha Dasgupta Department of Computer Science and Engineering Arizona State University Tempe AZ 85287-5406 USA [email protected] [Note: Written in 1997, Appeared in Encyclopedia of Electrical Engineering] 1. Introduction Network Operating Systems extend the facilities and services provided by computer operating systems to support a set of computers, connected by a network. The environment managed by a network operating system consists of an interconnected group of machines that are loosely connected. By loosely connected, we mean that such computers possess no hardware connections at the CPU – memory bus level, but are connected by external interfaces that run under the control of software. Each computer in this group run an autonomous operating system, yet cooperate with each other to allow a variety of facilities including file sharing, data sharing, peripheral sharing, remote execution and cooperative computation. Network operating systems are autonomous operating systems that support such cooperation. The group of machines comprising the management domain of the network operating system is called a distributed system. A close cousin of the network operating system is the distributed operating system. A distributed operating system is an extension of the network operating system that supports even higher levels of cooperation and integration of the machines on the network (features include task migration, dynamic resource location, and so on) (1,2). An operating system is low-level software controlling the inner workings of a machine. Typical functions performed by an operating system include managing the CPU among many concurrently executing tasks, managing memory allocation to the tasks, handling of input and output and controlling all the peripherals.

  • The Era of Microsoft? Technological Innovation, Network Externalities, and the Seattle Factor in the US Software Industry
    The Era of Microsoft? Technological Innovation, Network Externalities, and the Seattle Factor in the US Software Industry Edmund A. Egan Working Paper 87 January 1996 Edmund A. Egan is a Doctoral Candidate in the Department of City and Regional Planning at the University of California at Berkeley. - 1 - Abstract Microsoft Corporation, the largest company in the US software industry, has been under anti-trust scrutiny from the Department of Justice for most of the 1990s. In 1995, its planned acquisition of Intuit, Inc. prompted a Silicon Valley law firm, on behalf of unnamed complainants, to submit a White Paper to the DOJ, on the subject of Microsoft's long-term strategy. The White Paper, relying on the theoretical concepts of network externalities and lock- in effects, argues that Microsoft will use Intuit's products to attain monopolistic positions in network operating systems, on-line services, and electronic commerce, and will eventually be in a position to affect the content transmitted over electronic networks. This paper disputes that claim. First, an analysis of Microsoft's growth vs. the US packaged software industry a whole is presented, indicating that Microsoft actually has a fairly small share of total employment and sales. Secondly, a detailed review of the White Paper's argument is followed by a discussion of Microsoft's competitors, whose products also benefit from network externalities and lock-in effects. Ultimately, innovation will be more important than leverage for Microsoft. However, the paper argues that Microsoft's location in Seattle may prove to be a liability when it comes to rapid innovation; the corporation has grown much more rapidly than the Seattle software industry as a whole.
