The Windows operating system architecture also allows for single sign-on and also relies on user name and password verification. The authentication process for a Windows operating system at the server level can also be configured to validate the identity of the person logging in at the Windows domain and Microsoft Active Directory Service levels as well. Certificates can be assigned to specific applications, databases and processes within a Windows sever-based architecture and operating system configuration (Vellalacheruvu, Kumar, 2011).
Another significant difference between UNIX and Windows security is the definition of the security model itself. UNIX defines permissions to the file level using user name and password, and can also assign security levels of a given process as well (Takeuchi, Nakayama, 2006). In many UNIX operating system versions a UID and GID-based session will be started when a user logs in and attempts a specific application or system-level process. It is possible to add on additional security layers to these UID and GID sessions using Kerberos login authentication technologies and processes, in addition to investing in secured file system architectures as well (Takeuchi, Nakayama, 2006). All of these functional improvements to UNIX however come at a high price and tend to increase the low Total Cost of Ownership (TCO) this operating system provides. The UNIX security model is not as adept at managing security on objects, complex, multi-threaded processes and interlinked TCP/IP commands as well (Vellalacheruvu, Kumar, 2011). Like the many variations of UNIX, the Windows operating system architecture is continually going through a series of modifications and enhancements to become more secure. The Windows Active Directory architecture is designed to eliminate the need for inter-domain trust controllers and the complexities of security on the previous generation Windows NT and 95 architectures (Son, Lee, Jeon, Chung, Lee, Lee, 2011). Instead the Active Directory uses authentication layering technologies and Kerberos algorithm to increase security resiliency, making the operating system more difficult to hack into.
Both UNIX and Windows operating system architectures are multiprocessing, multi-threaded in that both support multiple processes or threads at the same time. Both are also designed to support multitasking, multiuser commands and environments, and multithreading of applications. The Windows architecture continues to promote Win32 and Win64 multithreading of applications for greater performance.
Configuring process management within each operating system is often done with utilities and on occasion with shell scripting. In Windows the majority of these functions are driven by graphical user interfaces (GUI). In UNIX however process management is often handled through shell scripts. As the UNIX architecture in general is not as flexible as the Microsoft one at integration, it is common to find shell scripts that are used for File Transfer Protocol (FTP) and TELNET sessions from one system to another. A shell script is shown below for transferring file.txt to a computer center via FTP command. These types of shell scripts are so pervasive enterprise software vendors use them for moving files from one location to another on UNIX-based servers their software runs on (Iyer, Lee, Venkatramen, Vesset, 2007).

FILE='file.txt' ftp -n $HOST <

Comparing UNIX and Windows operating system architectures on the variations in their kernel architectures, application programmer interfaces (API), security, approaches to process management illustrates how vastly different the design and development philosophies of each of these systems are. UNIX has a strong legacy in the scientific and engineering community and the level of customization to the kernel level shows how pervasive support and customization of this operating system is. Windows' architecture is more focused on ease of customization and support for a broader base of integration support, a lesson Microsoft must have learned from speaking with their enterprise customers who have hundreds of legacy systems they want to use in conjunction with Windows. Both operating systems have kernel architectures capable of supporting enterprise-level applications, and both also have security models that have been proven over time in distribute order management, database and transaction-intensive applications
(Son, Lee, Jeon, Chung, Lee, Lee, 2011). Ultimately the judgment of which is best is more a function of the specific enterprise or organizational need that is needs to be met and how the unique strengths of each of these operating systems meet them.

operating system can be simply defined as a "program that manages a computer's resources, especially the allocation of those resources among other programs" ("operating system (OS) (computing) -- Encyclopedia Britannica"). There is no definitive answer to the question that which is the best operating system that has been produced till date. Windows and MAC OS X are two of the renowned operating systems that are used all over the
Storage management, creating and maintaining a file system, and integrating them into networks also share a common set of functions that allow for programmer flexibility in terms of their use and sequencing through an application. These functions are specifically called as part of the kernel of the Linux operating system, and as a result they can be selectively updated very quickly. A full recompile of the entire operating system
NET development platform, further accelerating performance on the Windows 7 desktop and server operating systems (Wildstrom, 2009). This strategy worked as it gave Microsoft the opportunity to create a highly differentiated system level of performance wills also ensuring backward compatibility to previous generation applications and their respective API calls (Bradley, 2009). Microsoft also took the added step of ensuring the MinWin kernel could also manage a high level of transaction
Macs and PC. A copy of this is outlined to show and contrast the difference between Macs and PCs. COMPARISON OF MACS AND PCS Which is better: MACS or PCS? Macintosh computers are elegant and easy to use, but PCs are cheaper and have a vast array of products with them. The Apple computer has been around for a long time, but PCs are found in more stores. The best way
Using this index, XP outperformed Windows 7 in almost every category. This test found that XP would be better for running games, but the author noted that newer games that require DirectX 10 or 11 will not run on XP. Of course, some newer software will not run on XP at all such as Windows Live Movie Maker. It would be unrealistic to expect newer software that was developed long
Microsoft has provided legacy API support in the latest WinHEC-delivered kit of the Microsoft Windows Vista Developer's SDK to ensure upward and backward compatibility. Having a more streamlined kernel is also going to give the user interface greater speed and ability to respond to more complex imaging tasks. As a result, Microsoft is planning to have Tablet PC technology and touch-screen support on all versions of Windows 7 in
As the RADIUS protocol is a connectionless protocol it is low-level in terms of its functionality and cannot support the more complex unmet needs of WLANs and ISPS today (Wirbel, 2004). Conversely, Diameter supports the Transmission Control Protocol (TCP) and the Stream Control Transmission Protocol (SCTP) have the functionality necessary to provide connection-oriented controls over flow control and arbitrating packets across the network. This is one the most significant
