...Running head: UNIX vs. MS vs. MAC 1 CIS-155 Final - UNIX vs. MS vs. MAC UNIX vs. MS vs. MAC 2 Abstract This paper will explore the history of UNIX, Microsoft (MS), and Macintosh (MAC) operating systems. Not only will I discuss the history of these systems, but I will also dive into the pros and cons of each. The benefits of each over its rivals will also be discussed. Keywords: open source, UNIX, Windows, UNIX vs. MS vs. MAC 3 The topic of what operating system is best has been a long and heated one. But, in the long run, UNIX will beat its rivals in most categories hands down. As the reader will see throughout this paper, undisputed evidence will be presented that will detail exactly how UNIX based operating systems are superior. Operating systems (OS‘s) are a means for users to communicate with the computer. Each OS provides a set of commands for directing the operation of the computer. Without these operating systems to help as interfaces, each user would have to learn the command syntax, which can be very difficult. These operating systems can be menu-driven, which provides a set of menus and lets users choose desired functions from then, or they can be icon-driven, known as a graphical user interface (GUI). GUIs are very common these days and with them, users can choose an icon, usually with a mouse, to activate...

...Abstract Linux and Microsoft operating systems have been developed and marketed in two very different ways. Microsoft has become synonymous with monopoly and substandard software, while Linux is based on free, open source and the concept of open standards, full disclosure and sharing. Microsoft attempts to discourage consumers from using the Linux solution by suggesting that the operating system is less than perfect, yet it remains blind to its own operating system's problems existent within Windows 95/98 and Windows NT. It's a well-known fact that Microsoft dominate the software market despite these facts. Are they operating within legal and ethical boundaries? And is it possible that they could fall from grace because of this? `When you say "I wrote a program that crashed Windows", people just stare at you blankly and say "Hey, I got those with the system, *for free*".' (Linus Torvalds) Introduction Linux and Microsoft operating systems have been marketed very differently. The objectives of the two factions are very different indeed. One seems to be oriented towards market domination, market cornering and making the most amount of money it can, and the other towards creating a free, open source operating system. This may sound too simplistic with the two extremities, and may be a bit more complicated. This report will investigate into the differences in the way that the Linux and Microsoft operating systems have been developed and marketed, and how Microsoft...

...Windows® vs. Linux It was inevitable that operating systems—and computer system in general—at least in the year 2012, are not anything like those envisioned by science fictionists, novelists, and screen writers of the early and mid 20th century. For the most part, they saw computers as a single entity one system controlling everything, like a giant brain reaching out and serving each end-user anonymously. And there were surely no “blue screens of death.” Computers today come in hundreds of flavors. Let’s say you want a tablet instead of a keyboard, no problem. Need to run a multi-million dollar company with an extensive database from home? No problem. Interfaces and operating systems and software applications and hardware upgrades and I/O devices provide each and every person on the planet a customized computer experience. We should thank capitalism for many of the technological advances that have come about over the past fifty years. After all, money has a tendency to flow to the products that make our lives the most enjoyable. Three of the most notable advances in computer history are servers (formerly known as mainframes), Microsoft Windows, and the Linux operating system. Each one in its own right could fill volumes. However, the objective of this paper is to simply highlight a few of the most prominent features each of these advances has to offer. We will start with the most notorious MS Windows®. Microsoft has been in the computer industry...

...TCP Timestamping can be used to retrieve information about your system that you may not wish to be public. I started investigating this after some discussion of NetCraft's (http://www.netcraft.com/) server uptime stats, and their reliability. Ant Mitchell was very polite in telling me NetCraft would not disclose how they obtain these figures, only that he feels they are reliable. So I started looking into how they could get this information. What I discovered was TCP Timestamping is equal to the uptime (after a fashion) of many systems, and as such can give you extra information about the running system. What is Timestamping? How can it be used to gain information about a running system? Timestamping is a TCP option, which may be set, and if set takes 12 bytes in the header (for each packet) in addition to the 20 bytes a TCP header normally takes. This is exclusive of any other options. What good is this overhead? According to RFC1323: "The timestamps are used for two distinct mechanisms: RTTM (Round Trip Time Measurement) and PAWS (Protect Against Wrapped Sequences).". I suggest that anyone interested in TCP Timestamps read RFC1323 (these are not the IP timestamping options). The fact that timestamping exists isn't anything special in itself, but how the value is populated and how the value is set is somewhat interesting. 4.4BSD increments the timestamp clock once every 500ms and this timestamp clock is reset to 0 on a reboot...

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...

...Android vs iPhone Junyao Zhang April 12, 2010 This is a complete analysis and comparison between Android and iPhone OS. The rest of this report is organized as follows. Section ?? outlines the system architecture, history and detail management configuration. Section ?? discusses the iPhone system. In Section ??, a comparison between these two systems is presented. 1 Android Android, originally meaning “robot”, is a mobile operating system using a modified version of the Linux kernel. It was initially developed by Android Inc., a firm later purchased by Google,[?]and lately by the Open Handset Alliance[?]. It allows developers to write managed code in the Java language, controlling the device via Google-developed Java libraries.[8] It empolys the software stack architecture, as shown in Figure 1. • Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack. It is implemented by programming language C. • The middleware level includes Runtime and Libraries. The Runtime includes core libraries, providing most of the functionality available in the core libraries of the Java programming language, and Dalvik virtual machine which allows every Android application runs in its own process. The Libraries is used by various components of the Android system, such as Media Libraries, 3D libraries...
