Introduction to Operating Systems

Brief history of triad different Operating frames (OS). For the collar OS I chose Windows, Linux and apple placements. Windows 1. 0 The truly early transformation of Windows, Windows 1. 0, elementary interface that used thingummys, equivalent the calendar and calculator, however it gained little popularity. Released in 1985, the arranging of rules had elemental functionality, introduced the first adaptation of MS paint and a primitive word mainframe. Windows 2. 0 Released in 1987, was non much best(p) than the first.While 2. 0 introduced devil original staples Excel and Word to users 2. went under cease when mackintoshintosh sued Microsoft for mimicking the look and feel of their menstruation operating(a)(a)(a) strategy. The lawsuit was dropped. Windows 3. 0 The trigger of realistic memory, meliorate graphics, and the ability to multitask assisted be active Windows to sell 10 million copies. In fact, while it was released in 1990, Windows 3. 0 wasnt c ease until 2001. Windows 3. 1 A pseudo-release for Microsoft, Windows 3. 1 contained fixes and improve font functionality. Microsoft continued to develop a novel release, Windows NT, hoping it could be released as a continuation of Windows 3. and 3. 1. Unfortunately, issues with driver support and bundle program system meant it was time for a new version alto claimher.Windows 95 The change from 16-bit to 32-bit, Windows 95 was intentional for increased compatibility and ultimate user-friendliness. Became clear that consumer computing machines would bring about the future, Windows 95 was offered on newer figurers all because it lacked or so backwards compatibility at first. Newer releases and patches make the version easier to use on older machines, by 1995, Microsoft had achieved a widespread interest in home computers.Windows 4. The follow-up to Windows 3. 0, Windows 4. 0 released in 1996 with minor improvements and is not considered a major Windows release. Windows 98 As consumer computers became widespread, Windows 98 improved hardw ar and hardw are drivers, Internet Explorer, and at last Internet connection sharing. Released in 1998, with a new release in 1999, Microsoft 98 was the first release designed specific exclusivelyy for consumers, as opposed to the business or technology set. Windows 2000 Windows 2000 do everyones lives easier increasing the bout of plug and play devices compatible with the OS.Windows ME (Millennial Edition) was excessively released, crack the system recovery puppet to tending return a crashed computer to its last known operating settings. Windows XP The system designed for ease and stability, Windows XP was released in 2001, offering plenty of ease and functionality for laptop and scope users. The OS was designed to offer users help by means of a comprehensive help center, gave users the ability to consume a derive of different types of media. Windows conniption Widely considered a flop in technology circ les, Windows Vista was released in 2006.Vista had high system requirements and suffered issues with carrying into action and security. The OS also tended to bolt laptop batteries. The version lasted only three years, during which some users downgraded back to XP avoiding the pitfalls of Vista. Windows 7 For this present-day(prenominal) release of Windows, Microsoft learned its mistakes with Vista and take a crapd an OS with speed, stability and minimal system requirements. Microsoft ditched the gadget bar from Vista, replacing with a spick-and-span feel. This version was released in 2009. Windows 8 This current Windows release is getting a jalopy of attention.With redesigned Metro-style user interface and Windows Store, this version is, one time again, redefining what Windows is. It also comes with integrated antivirus protection, a virtual hard disk and a new platform based on HTML5 and JavaScript. Windows 8 promises faster boot time, touchscreen compatibility and the abili ty to create a bootable USB flash drive. It may not be enough to get sight to switch from Windows 7, but at least(prenominal) its a glimpse into the future of the Windows operating system. Linux is an OS for your computer.Like the macintosh and Windows systems, it provides the basic computer services needed for soul to do things with a computer. It is the middle point between the computer hardware and the software applications you run. Full applications keep up capabilities resembling bold face type and picture editing tools. no(prenominal) of this is on hand(predicate) through the OS. Yet all of it is done by communicating with the machinery of the computer through the OS. You may highlight a word in word processor and tell it that you want that word in bold type, but the OS tells the computer which pixels (or part of the screen) to darken.Linux was demonstrable by Linus Torvalds and a band of programmers who voluntarily developed the marrow program of the system (aka, the kernel). That program was in the beginning compatible for an early(a) operating system called Minix, but later development made it usable with wildebeest software. wildebeest is marked like the animal and stands for GNUs Not Unix. It was a project conceived by Richard Stallman in 1983 in response to the increasing tendency of software companies to copyright their software under impairment that prohibited sharing. GNUs purpose to develop a wholly free system.It had achieved significant hand toward this goal by the time that Linus and another(prenominal)s had developed their kernel in the 1990s. While umteen another(prenominal) people refer to the combination of the two as Linux, this is not correct. The kernel feature with GNUs free software is properly called GNU/Linux. Both the kernel and the software are freely easy under licensing that is sometimes called copyleft. Where traditional copyright was meant to restrict physical exercise and ownership of a copyrighted particular to as few people as possible, inhibiting development and growth, GNU/Linux is different.It is released under scathe designed to en certain(a) that as m some(prenominal) people as possible are allowed to receive, use, share, and modify the software. That license is called the GPL (GNU Public License). Ubuntu depends on the Linux kernel and includes many GNU applications. So, when psyche speaks of the Ubuntu kernel for a computer, they are actually talking about a novel version of the Linux kernel. Most of the applications that are available for Ubuntu are either part of the GNU collection or are released under the GPL. For apple not much schooling was found.However, they provide a timeline of the OS. 1978 In June of 1978 orchard apple tree introduces apple DOS 3. 1, the first operating system for the apple computers. 1984 Apple introduces body 1. 1985 Apple introduces governing body 2. 1986 Apple introduces System 3. 1987 Apple introduces System 4. 1988 Apple in troduces System 6. 1991 Apple introduces System 7 operating system May 13, 1991. 1995 Apple allows other computer companies to clone its computer by announcing it is licensed the Macintosh operating system rights to Radius on January 4. 1997 Apple introduces Mac OS 8. 997 Apple buys NeXT software program Inc. for $400 million and acquires Steve Jobs, Apples cofounder, as a consultant.1999 Apple introduces Mac OS 9. 2001 Apple introduces Mac OS X 10. 0 mark named Cheetah and becomes available process 24, 2001. 2001 Apple introduces Mac OS X 10. 1 inscribe named Puma and becomes available on September 25, 2001. 2002 Apple introduces Mac OS X 10. 2 code named Jaguar and becomes available on lordly 23, 2002. 2003 Apple introduces Mac OS X 10. 3 code named Panther October 25, 2003. 2004 Apple introduces Mac OS X 10. code named Tiger at the WWDC on June 28, 2004. 2007 Apple introduces Mac OS X 10. 5 code named Leopard October 26, 2007. 2008 Apple introduces Mac OS X 10. 6 code named hundred Leopard and MobileMe at the WWDC on June 9, 2008. Factors that may suggestion users to upgrade the OS they use is stability, performance and security. Windows Vista had many issues in these areas make users switch back to XP. For other OS not quite sure if any had serious issues, though the newer versions gave more resolve to upgrade. My soulfulnessal use of OS has only been with Windows and Apple IOS on a cell resound.Never a fan of Apple but Windows I like. It has been so big since I used XP that I am unsure of why I switched other than I had to because my new PC had a different version. Despite the problems with Vista I was like Sheldon when using 7 the first time, 7 is too user friendly. However, I love Windows 7 and do not intend on upgrading until I have no choice. For Apple use on a cell phone in that location may be a guess I do not like this IOS because it is only through a phone and they have not yet made phones run just like PCs.I do plan on buying an Ap ple computer presently so I can get more experience with the OS. Linux is an OS I am not even sure if I ever used, it is possible I did when computers first came out because my neighbor was a computer fan and was also the person that got me into technology. That was so long ago that I barely recall anything I did through her computers, all I remember is I had to tell the PC what to do like command prompts. If Linux OS is the same, than I do enjoy this system.
