There is also the essence of flexibility and effectiveness in addressing protective needs and obligations in the context of the operating systems. Access matrix has the ability to address diverse needs through implementation of the concept of the subject and objects in the development of interactive operations (Besson et al
The main advantage is the ability to the mechanism to limit the operations or actions of the legitimate user effectively and efficiently. This is through constraining what the users can do directly and programs the operating system can execute on behalf of the user while exploiting the essential resources or systems (Shakya et al
It refers to the concept of the resource protection or a model for the purposes of protection of the operating system. The mechanism was first applied in 1971 under the influence of an American computer scientist known as Butler Lampson (Tripunitara et al
The second objective is to offer quality allocation of the scarce resources among the competing processes with the aim of maximizing the performance of the system under the influence of minimal overhead or operational costs. The development of the systems in the modern society has let to the realization of more powerful, specific, and specialized protection systems and mechanisms in the form of language-based protection (Harrison et al
This is vital for the purposes of effectiveness and efficiency in service delivery. It is also ideal to note that the developer does not need to provide the means of enforcement directly hence beneficial towards operation by the user (Rossbach et al
This occurs even if the underlying operating system fails in the provision of advanced protection mechanisms. The security of the compiler relates to the integrity of the system (Sharairi 2011)
The concept of user authenticity is weak and susceptible to numerous attacks. The protection mechanism also relates to the ability of the user to maintain the user ID and password secret for the purposes of minimizing threats and attacks (Weber 2010)
Another benefit is the ability of the user to manage change of passwords in the context of each user's computer or domain level. This is ideal for effectiveness and efficiency in the exploitation of the resources towards protection of the operating system (Cheswick 2013)
Still, the reduction in volunteerism for the armed services necessitates continued development of the Smart Ship concept, preferably with secure yet compatible elements with commercial software. (Slabodkin, 1998) Works Cited Intergraph Solutions Group
Both Microsoft Windows XP and Windows 7 share a common legacy of kernel-based design that completely changes the dynamics of how applications are created on these platforms relative to Linux (Sliwa, 53). Comparing the kernel architectures of Windows XP and Windows 7 to Linux shows how the latter evolved from the basis of UNIX operating system design criterion, while the latter is a progression from the Windows operating environment Figure 1: The Windows XP and Windows 7 Kernel Source: (Antoniol, et
The architectures, pros and cons or advantages and disadvantages of these operating systems, pricing, and feature analysis is included in this analysis. Architectural Differences All three of these operating systems vary most significantly at the architectural levels, as the design philosophies of the architects Microsoft vary significantly from Linus Torvalds' initial designs in the early 1990s to today (Foley, 36)
al). In the BSD-based versions of Linux, the security levels can also be defined down to the object-by-object level with significantly streamlines programming and development (Kennedy, 46)

Unless parents work on Macs, the logical choice is the PC. If the application is heavily design oriented and price is no object, the Mac is the choice (Frakes, 2006)
However, one manufacturer of Pcs never really dominants the entire market year after year, but instead, the Windows OS and Office 2010 from Microsoft, are the dominant programs in the global marketplace with over 92% market share. Mac's crash less, have superior electronics overall (one company controls QC and manufacturing, assembly and distribution), but Macs are quite a bit more expensive than PCs, even ones that are similarly configured (Mills, 2010)
Gone were the days in the late 1980s in which the popular view was that one would never ever need to use a Megabyte of memory; now we are seeing standard Gigabytes and inexpensive Terabytes. New chip design also contributed to quad and greater core processing systems, particularly in memory allocation and types of graphics available (Willington, 2010)
It is based on OSX's UNIX and UNIX security which makes it more stable as compared to the Microsoft Windows operating system. There are no problems like spyware and virus in the Mac OS X which use to occur in Microsoft Windows (Lewis)
Microsoft made the decision to create the MinWin kernel architecture as it is configurable prior to run-time in an attempt to compete with the functionality of Apple's OS X, the many variations of UNIX and the greatest threat to Microsoft, open-source Linux operating systems as well (Wildstrom, 2009). Another factor Microsoft took into account in moving to a more kernel-based architecture in their latest operating system was the need to emulate virtualization across multiple process streams while retaining compatibility for the previous generation Win16 and Win32 API development architectures (Bradley, 2009)
Another factor Microsoft took into account in moving to a more kernel-based architecture in their latest operating system was the need to emulate virtualization across multiple process streams while retaining compatibility for the previous generation Win16 and Win32 API development architectures (Bradley, 2009). Microsoft also embraced the kernel concept due to the need to stabilize the rapidly changing nature of its IRQ interrupt structure which had for well over a decade served as the means for the operating system to arbitrate for resources in order to complete I/O tasks (Forgione, Smith 1993)
The use of APIs and advanced security routines for managing the overall performance of .NET and ASP-based applications will continued to dominate the Windows 7 operating system roadmap as well (Lamb, 2006)
