Using a novel approach to consider the available literature and research, this book focuses on the psychology of social media based on the assumption that the experience of being in a social media has an impact on both our identity and social relationships. In order to ‘be online’, an individual has to create an online presence – they have to share information about themselves online. This online self is presented in different ways, with diverse goals and aims in order to engage in see more different social media activities and to achieve desired outcomes. Whilst this may not be a real physical presence, that physicality is becoming increasingly replicated through photos, video, and ever-evolving ways of defining and describing the self online. Moreover, individuals are using both PC-based and mobile-based social media as well as increasingly making use of photo and video editing tools to carefully craft and manipulate their online self. This book therefore explores current debates in Cyberpsychology, drawing on the most up-to-date theories and research to explore four main aspects of the social media experience (communication, identity, presence and relationships). In doing so, it considers the interplay of different areas of psychological research with current technological and security insight into how individuals create, manipulate and maintain their online identity and relationships. The social media are therefore at the core of every chapter, with the common thread throughout being the very unique approach to considering diverse and varied online behaviours that may not have been thus far considered from this perspective. It covers a broad range of both positive and negative behaviours that have now become integrated into the daily lives of many westernised country’s Internet users, giving it an appeal to both scholarly and industry readers alike.

The enterprise data center has evolved dramatically in recent years. It has moved from a model that placed multiple data centers closer to users to a more centralized dynamic model. The factors influencing this evolution are varied but can mostly be attributed to regulatory, service level improvement, cost savings, and manageability. Multiple legal issues regarding the security of data housed in the data center have placed security requirements at the forefront of data center architecture. As see more the cost to operate data centers has increased, architectures have moved towards consolidation of servers and applications in order to better utilize assets and reduce "server sprawl." The more diverse and distributed the data center environment becomes, the more manageability becomes an issue. These factors have led to a trend of data center consolidation and resources on demand using technologies such as virtualization, higher WAN bandwidth technologies, and newer management technologies.The intended audience of this book is network architects and network administrators.
In this IBM® Redbooks® publication we discuss the following topics:


The current state of the data center network
The business drivers making the case for change
The unique capabilities and network requirements of system platforms
The impact of server and storage consolidation on the data center network
The functional overview of the main data center network virtualization and consolidation technologies
The new data center network design landscape

For more than 40 years, IBM® mainframes have supported an extraordinary portion of the world's computing work, providing centralized corporate databases and mission-critical enterprise-wide applications. The IBM System z®, the latest generation of the IBM distinguished family of see more mainframe systems, has come a long way from its IBM System/360 heritage. Likewise, its IBM z/OS® operating system is far superior to its predecessors, providing, among many other capabilities, world-class, state-of-the-art, support for the TCP/IP Internet protocol suite.
TCP/IP is a large and evolving collection of communication protocols managed by the Internet Engineering Task Force (IETF), an open, volunteer, organization. Because of its openness, the TCP/IP protocol suite has become the foundation for the set of technologies that form the basis of the Internet. The convergence of IBM mainframe capabilities with Internet technology, connectivity, and standards (particularly TCP/IP) is dramatically changing the face of information technology and driving requirements for ever more secure, scalable, and highly available mainframe TCP/IP implementations.
The IBM z/OS Communications Server TCP/IP Implementation series provides understandable, step-by-step guidance about how to enable the most commonly used and important functions of z/OS Communications Server TCP/IP. This IBM Redbooks® publication explains how to set up security for your z/OS networking environment. With the advent of TCP/IP and the Internet, network security requirements have become more stringent and complex. Because many transactions come from unknown users and from untrusted networks such as the Internet, careful attention must be given to host and user authentication, data privacy, data origin authentication, and data integrity. Also, because security technologies are complex and can be confusing, we include helpful tutorial information in the appendixes of this book.
For more specific information about z/OS Communications Server base functions, standard applications, and high availability, refer to the other volumes in the series:


"IBM z/OS V1R11 Communications Server TCP/IP Implementation Volume 1: Base Functions, Connectivity, and Routing," SG24-7798
"IBM z/OS V1R11 Communications Server TCP/IP Implementation Volume 2: Standard Applications," SG24-7799
"IBM z/OS V1R11 Communications Server TCP/IP Implementation Volume 3: High Availability, Scalability, and Performance," SG24-7800
In addition, "z/OS Communications Server: IP Configuration Guide," SC31-8775, "z/OS Communications Server: IP Configuration Reference," SC31-8776, and "z/OS Communications Server: IP User's Guide and Commands," SC31-8780, contain comprehensive descriptions of the individual parameters for setting up and using the functions that we describe in this book. They also include step-by-step checklists and supporting examples.
It is not the intent of this book to duplicate the information in those publications, but to complement them with practical implementation scenarios that might be useful in your environment. To determine at what level a specific function was introduced, refer to "z/OS Communications Server: New Function Summary," GC31-8771.
