The operating system (OS) is a collection of software to control the computer tasks and manage proper utilization of the hardware resources. The basic operating systems are the Linux, UNIX, Mac and Microsoft Windows. There are several and diverse components of an operating system that include but not limited to the file management, security, memory and process management. The following paragraphs present the comparison of basic operating systems with respect to the above given features (Solomon, Russinovich & Polze, 2006). The file management system refers to the organization, management and manipulation of computer data in documents and files that is provided by the file manager through a graphical user interface. The computer documents and files can be created, edited, viewed and deleted from the computer memory as well as the files can be arranged in computer directories. The process of file management differs with respect to the operating system as presented in the following paragraphs. There are several file managers used by Microsoft Windows only that include but not limited to the Altap Salamander, FAR Manager, File Manager, Windows Explorer etc. The files are placed in the folders and the index contains the file information known as File Allocation Table (FAT). One of the latest file management systems of the Windows is the New Technology File System (NTFS). The NTFS store owner name, it provides POSIX file permissions, creation timestamps, last access timestamp, and last content modification timestamp. The Mac operating system uses the file managers that include: the Disk Order, Finder, Path Finder, and Xfile. The Disk order file manager provides the graphical user interface and shows the files as list view and tw... ... middle of paper ... ...Murphy, P. (2004). What Differentiates Linux from Windows?.

1.1 Describe Systems and Procedures for Storing and Retrieving Information Collect documents to be filed, sort in to alphabetical, numerical or chronological order, find the relevant file and place the document inside after it’s divider, and return the file to its original place. Confidential files should be kept in a lockable cabinet and old documents should be shredded after the length of time outlined by the organisation. Electronic filing is similar but on the computer. It is important to name files so that they are easily recognisable by everyone who may need to access it. If the information is confidential it should be encrypted with a password to prevent unauthorised access.
No DBMS can do without this. If there is no file manager interaction then nothing stored in the files can be retrieved.
Develop a common sense file-saving system where the location of files with specific purposes is very intuitive.
The NTFS file system is used in all critical Microsoft Windows systems. It is an advanced file system that makes it different from the UNIX file systems that the original TCT was designed for. This document gives a quick overview of NTFS and how it was implemented. The biggest difference is the use of Alternate Data Streams (ADS) when specifying a meta data structure.
As the internet is becoming faster and faster, an operating system (OS) is needed to manage the data in computers. An Operating system can be considered to be a set of programed codes that are created to control hardware such as computers. In 1985 Windows was established as an operating system and a year earlier Mac OS was established, and they have dominated the market of the computer programs since that time. Although, many companies have provided other operating systems, most users still prefer Mac as the most secured system and windows as it provides more multiple functions. This essay will demonstrate the differences between windows
Then came Linus Benedict Torvalds. At the time he was a sophomore majoring in Computer Science at the University of Helsinki, his hobby also included computer programming. At 21 he found himself spending most of his time toying with computer systems, trying to see what he could do in order to push their limits and increase their functionality. The key missing in his tests was an operating system that had the flexibility craved for by professionals. MINIX was available, though it was still just a stu...
This document describes the final project for the course COEN 283 – Operating System. The project is team oriented, main goal is to select a topic related the Operating System concepts that should be either theoretical, in which new algorithm is analysis and simulate, in which subsystem/driver of an OS is prototyped. Provide the simulation/implementation code and explain the detail design in this report. This project will provide opportunity for students to perform research on topic of interest of operating system.
Linux has long been one of many operating systems that have been out to prove its worth in all types of environment. It is currently being considered for enterprise network purposes as well as data centers where it implies servers, workstations and any mainframes as needed. Choosing what operating system to use, whether it is open source or not, can be difficult, though. This paper projects the advantages and concerns of choosing an open source solution like Linux as administrators and users are becoming more aware of Linux running on both server and desktop systems. It is quickly being adopted in an ever increasing number of global corporations and government agencies.
The Linux file system does things a lot more differently than the Windows file system. For starters, there is only a single hierarchal directory structure.
The significance of the role of the Operation System (OS) in the overall Information Technology employment sector cannot be undervalued. Indeed, it is hard to talk about technical skill-sets or the practical application of such skill-sets without at least some underlying understanding of their context within a computer operating system environment. From hardware specifications and requirements, user technical support, system administration and security, to software development and system implementation, operating systems are an integral part of the information technology and computing world in all its aspects, and it is difficult to form a concrete demarcation between specialized careers in this industry and the concept of the computer operating system.

Both operating systems however diverge from each other in various ways, their question isn’t necessary which one is better but rather what makes them so different. When comparing two operating systems a user should take the following categories in for consideration, cost, user, user interface, usage, file system support, and security. The cost of a Linux operating is completely free versus a windows operating system which can range from prices such as $50.00 to $450.00. Even though Linux operating system is free however according to diffren.com their customer support is available for a
Linux or Windows? Open Software versus Proprietary software? When most people think of the best operating system, they first think of Windows and the OSX. However, Linux and many of its open source software are becoming more predominantly emerging in the current day and age. Linux widely touted for its small user base but Cost free, High Security, flexible user control and stability. Windows for it’s largely user base and wide customer range and support. In this paper, I will be discussing and doing a comparison of the advantages and disadvantages between Windows and Linux Servers.
