concept of open systems (Dunphy 1991, 44). POSIX® Portable Operating System Interfaces for Computing Environment, POSIX for short and it also known as, IEEE Std 1003.1. The standard was originally developed, in order to improve the portability of UNIX environment applications. It is a programmatic level interface core standard for portable operating systems and was created by a number of a different committees organized through the aegis of the IEEE. The POSIX standard provides source-level C language
Linux Networking Capabilities Linux is a Unix clone written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX compliance. It has all the features expected in a modern fully-fledged Unix, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management and TCP/IP networking. It runs mainly on 386/486/586-based PCs, using the hardware facilities of the
Windows XP vs. Mac OS X Architecture When looking at the interface of the Mac OS X Operating System and the Microsoft Windows XP operating system many similarities can be seen. The most obvious is the use of blue in the interface. In the core of the systems they both have a micro kernel which addresses thread management, space management and other communications at the system level and is more resistant to attacks from a virus. Mac OS X is a powerful development platform; it supports multiple
making its impact on the server industry? This paper will answer these questions. Linux – What is it? Linux is a free Unix-type operating system originally created by Linus Torvalds along with other developers in the industry. Linux is an independent POSIX (Portable Operating System Interface) implementation and includes true multi-tasking, virtual memory, shared libraries, TCP/IP networking and other features consistent with Unix-type systems. Linux was developed under the GNU General Public Licensing
A PHP is a hypertext preprocessor and it is widely used scripting language, which was designed for the purpose of web development for producing dynamic web pages. For this same purpose, a PHP code will beis embedded inside the HTML source document. The web server along with a processor module, which generates web page, will interpret this document. Knowing how to run PHP can be useful for people using the scripting language. PHP is a general-purpose programming language, a PHP code will be processed
MenuetOS: Bringing Old PCs Back to Life MenuetOS: Bringing Old PCs Back to Life MenuetOS is an extremely obscure operating system. It has a very low system requirement, and is mostly only used for outdated computers. It can run smoothly on a 50MHz processor with only 32MB of RAM (MenuetOS, 2010). MenuetOS also has desktop effects, such as transparent windows and three dimensional previews while switching programs. While MenuetOS is designed to run on older hardware, it’s a new operating
Linux is a trademark owned by Linus Torvalds [1]. It is an operating system which is powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux
Windows XP File Processing Within Windows there are two methods that a user or administrator can obtain access to files stored on the hard drive or media source. In the Windows operating system, files that are operating system specific (files needed in order for the operating system to work) are normally on the primary drive which is usually the C: drive. On a Windows based PC during the setup process, a user has the choice of where the operating system files are stored and what file system Windows
Abstract—High Performance Computing (HPC) provides support to run advanced application programs efficiently. Java adaptation in HPC has become an apparent choice for new endeavors, because of its significant characteristics. These include object-oriented, platform independent, portable, secure, built-in networking, multithreading, and an extensive set of Application Programming Interfaces (APIs). Consequently multi-core systems and multi-core programming tools are becoming popular. However, today
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
Introduction This paper discusses about the historical event that takes place within the operating system and their recent development and progression. Therefore it is essential to have a clear comprehension on the operating system that is still accessible to recognize its fundamental strengths and weaknesses. Hence, it is imperative to evaluate the operating system we are reviewing to distinguish between them. Meanwhile, this paper also inspects on the difference between the open source and proprietary

Linux is an OS for PC workstations that fully functional using graphical user interface (GUI). Linux is a Unix-like and POSIX-compliant computer. OS assembled on this platform is under the model of free and open source software development and distribution. Linus Torvalds was defining component of Linux as Linux kernel, the operation system kernel first released on 5th of
Simultaneous Multithreading Simultaneous multithreading ¡ª put simply, the shar-ing of the execution resources of a superscalar processor betweenmultiple execution threads ¡ª has recently become widespread viaits introduction (under the name ¡°Hyper-Threading¡±) into IntelPentium 4 processors. In this implementation, for reasons of ef-ficiency and economy of processor area, the sharing of processorresources between threads extends beyond the execution units; ofparticular concern is that the threads
