...Windows, Linux and Mac Operating system Booting Process: a Comparative Study Prof. Amar Rajendra Mudiraj Assistant Professor MIT (E), Aurangabad,Maharashtra, India. Email:amarmudiraj@gmail.com Abstract This paper presents a comparative study of Booting Paradigm of Windows, Linux and Mac, the three popular operating systems. Booting process is the essential and first step perform by the OS after this process execution all other processes can get the chance to execute , so we may say that booting is the first process because of which all other OS processes can execute. This experimental study gives an overview on the similarity and difference in Booting Process. As every operating system have to initially do the booting and as every OS providing different feature of each others, the paper is highlighting those micro and essential similarities and differences having by the operating systems during the Booting Process. Keywords: Booting, Cold booting, Worm booting, Linux Booting, Windows Booting, Mac Booting. In Worm Booting the computer get restart without shutdown the system, in which the system application and memory just get cleared and then reloading the operating system in primary memory. With the above two booting types we also have some other flavor in the computer booting like Sleep, Hibernate. Power - ON Load Instruction from ROM Detect OS from HDD 1. Introduction Find Attached H/W Booting Process is the first step gets happened in the computer system when you switch on...

...Operating Systems most favored by fortune 500 companies are Windows, Red Hat Linux and AIX. Operating Systems perform basic task that supports the use of input, the printers, drivers, keyboard and the display screen. The operating systems support different programs and users running on it at the same time. It also supports the security and user abilities. Operating systems provide software platforms on top of applications, like Java, Visual Basic etc. These applications have to be written to run operating systems. There are several choices of operating systems DOS, OS/2, Windows, AIX, and Linux. The two main operating systems are Windows and Linux/Unix. “And they have a competitive history and future” (Haas). Before we get into the technicalities of either operating system, let’s examine the environment that these two systems evolved from, or the culture from whence they came, if you will. “Corporate culture pertains to the identity and personality of the company we work with, either in the private or public sectors. All companies have a culture; a way they behave and operate. They may be organized and disciplined or chaotic and unstructured. Either way, this is the culture the company has elected to adopt” Brice, (2012). “Microsoft may appear to some people as a company without culture, but that impression changes upon entering the Sigma Building, which houses Microsoft Research Asia. Chatting with the great minds at Microsoft Research Asia, one is reminded...

...Kristianne and an younger sister named Libby. Earlier in his life, Gates parents had a lawyer career in mind for him. But, that, dream went to side lines, when he was in the 8th grade. Bill Gates Education At the age of 13, bill enrolled for Lakeside school, an exclusively preparatory school, which is said to be a turning point. It all began to create a new page in the history, when the mothers club at the school used funds arisen out of profit from sale of some miscellaneous things collected in the club, to purchase an ASR-33 teletype terminal and also a block of General Electric computers for school students. Gates developed a special interest in GE terminal computer and went ahead to learn and develop programs using programming language BASIC. He was excused from attending the Maths classes, while doing so. He developed his first major program on his own, which is an implementation of game called as tic-tac-toe. This is, perhaps the turning point in his career. In fact, Gates was always thinking, how the machine could execute his program perfectly without giving any problems. I think, as a professional programmer, that also one way, helped Gates to understand computer programming better. Laying first foundation stones, for a great distinguished career Gates got a chance to work in Computer Center Corporation (CCC), along with three other Lakeside students banned by the same CCC for the summer, after it caught them exploring...

...configuring and administering a client Operating system Introduction The operating system is the most important program that runs on a computer. Computers rely on an operating system to supply the interface for interaction between the user, applications and hardware. The operating system is responsible for booting the computer and manages the file system. It is possible for an operating system to support more than one user task or even CPU (central Processing Unit). All computers must have an operating system it is the program that controls almost all of the functions on your computer. Any decisions that are made during the process of installation will have significant ramifications on how people will use that computer throughout its operational lifetime.

...The operating system that we use on our computers is the most important program that we have. Every computer used for home or business must have an operating system to run other programs. They perform basic tasks and recognize the input from the keyboard and output to the display screen. They keep track of files stored on your computer and control disk drives and printers. (Beal, N.D) There are five basic functions of an operating system. They are: * Booting the computer * Performing basic computer tasks like the mouse and keyboard * Provides a user interface such as a command line or a graphical user interface * Handles system resources such as a computer’s memory * Provides file management which is the way the operating system manipulates, stores, finds and saves data (N.A., N.D.) The difference between Windows, Linux and Mac OS is that windows is designed to run on PC’s. All three are operating systems, but the internal architectures are different in each. And PC’s are very inexpensive for a basic model. (Sinoun, 2011) The Windows operating system is pretty versatile, and can be installed on PCs having variable amounts of resources. There are versions of Windows that can be installed on PCs having as little resource as 233 MHz processor and 64 MB RAM. Windows users get good choices for their operating systems, based on the system resources they have. An even greater benefit of Windows users is the user-friendliness of the operating system.
