Windows 7 Operating System Guide to Operating Systems The role of operating systems continues to be critical to the overall performance of enterprise information systems globally. In the majority of enterprises today there is a wide variation in the type of operating systems used, as the information needs vary significantly across organizations. The intent of this analysis is to evaluate the Microsoft Windows XP, Windows 7 and Linux operating systems. The architectures,

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

Network Operating Systems operate on servers, offering them the capacity of managing information, groups, users, applications, networking functions, security, etc. Network operating systems' key role is enabling sharing of printers and files among several computers within a given network (normally a LAN (local area network) or private network) (Sen, 2016, p. 5) The environment network operating systems manage, comprising of loosely interconnected machines, will be taken up for discussion in this

Linux Kernel Analysis Much has been written in praise of the Linux (Crandall, Wu, Chong, 359), (Parnas, 112), (Baliga, Iftode, Chen, 323), and its use of preemptive multitasking memory architectures to manage process control, file management, device management, information maintenance and communications subsystems securely and effectively. The Linux modular design, lack of reliance on Remote Procedure Calls (RPC), and use of UNIX-based system administration all are often cited as factors in how

Companies such as XYZ Widget Corporation are well situated to take advantage of burgeoning markets in developing nations, particularly in Asia and Africa. 2. XYZ can grow its business by expanding its operations to certain developing nations in ways that profit the company as well as the impoverished regions that are involved, particularly when marketing efforts are coordinated with nongovernmental organizations operating in the region. 3. Several constraints and challenges must

Assurance and Security (IAS) Digital forensics (DF) In this work, we take a look at three laboratory-based training structures that afford practical and basic knowledge needed for forensic evaluation making use of the latest digital devices, software, hardware and firmware. Each lesson has three parts. The duration of the first section of the three labs will be one month. These labs would be the largest labs. The Second section would
