Sample Essay

OpenSuse 11.1 features are a new version of Kernel and New KDE environment, both giving it fast booting and system taking speed while providing an overall acceptable level of performance to the user (Müller, 2008).

Mac OS X (Snow Leopard)

In a performance review of Snow Leopard, Mac Performance Guide Website states that “… Snow Leopard booted into the 64-bit kernel shows a consistent performance advantage over Leopard, and even more advantage over 32-bit Snow Leopard as well. Performance gains of up to 30% were observed, making Snow Leopard by far the best value for the money in a long, long time.” (Chambers, 2009).

Features

Windows Vista

Regarding the enhanced user experience of Vista, Vista Sense website says “Microsoft has been learning from user feedback about the usability of their operating systems and now most of the suggested features are loaded in Windows Vista ” (Vista Sense, 2006). Talking about User Account Protection security feature of Vista, Paul Thurrott of Supersite for Windows says “The problem with UAP is that it throws up an unbelievable number of warning dialogs for even the simplest of tasks. That these dialogs pop up repeatedly for the same action would be comical if it weren’t so amazingly frustrating. It would be hilarious if it weren’t going to affect hundreds of millions of people in a few short months. It is, in fact, almost criminal in its insidiousness.” (Thurrott, 2006).

OpenSuse 11.1

OpenSuse 11.1 has been further refined from its predecessors. It now uses Sudo to allow its users to control the administrative task which makes it easier for newcomers to use OpenSuse.  The graphical software manager is faster than ever.   Downloads and installations from the repository are also much faster than before (OpenSuse, 2009).

Mac OS X (Snow Leopard)

Snow Leopard has most of its OS part rewritten in order to speed up the working of the operating system. It also takes less space on hard disk. Benchmarks have suggested that the system tasks such as shutdown, sleep, and wake up as well as copying to and from the external drives are faster. Most impressive is how Safari browser sandboxes the plug-ins. Under the hood changes show Apple attempting to make a clean break from the past, finally mothballing the grey-bearded QuickTime API from 1991. In its place, the new QuickTime is well capable of the demands of modern video. Except that due to legacy support, QuickTime 7 exists behind the scenes and the system calls the relevant back-end as and when it needs to. Exchange support is now built directly into the OS, supporting Exchange 2007 (SP 1) or later (TechRadar, 2009).

Technology

Windows Vista

Vista has a new feature called the Windows Mobile Device Center which looks nicer. Vista gives you some basic support like file explorer for Windows Mobile systems and it allows you to upload or download files or pictures. Vista’s Movie Maker now also supports DVD burning capabilities (Active Network, 2009).
