engagement without someone there to interact with visitors. Tikkanen et al. (2009) also found in a survey of 200 Second Life users that “72 % of respondents were disappointed with the marketing activities in Second Life and only 7% considered current virtual world marketing activities to be having a positive influence on brand image and on their buying behavior" (p. 1364). Another study of Second Life by Mackenzie, Buckby & Irvine (2009) surveyed 20 businesses on Second Life and found there was an “apparent

sprung from the ability to run several virtual machines on one physical computer resulting in saving companies the cost of having to purchase additional computer systems or servers. Just like their physical counterparts, the task of securing a virtual computer environment poses many challenges for IT technical personnel. The benefits of server virtualization have been touted over and over again to include load balancing, lower power consumption, ease of management, isolation from attackers and malware

a physical address and a virtual address? Answer: By physical address, we refer to the actual address of hardware physical memory (RAM). That means when a variable is stored at a physical address, that's the place where it's really stored in the RAM chip. If we are using physical addressing, a process also “knows” the entire layout of the physical memory. With virtual addressing, all process memory accesses go to the Memory Management Unit, which then maps the virtual address to a physical one

Virtualization Virtualization is “the process of creating a virtual, rather than physical, version of something” (Virtualization, 2015). In the IT industry this refers to technology that utilizes software to imitate hardware and create virtual computer systems. One example of this is to use a single physical device such as a server and logically divide up its resources (Processor, memory, and storage) to create smaller , separate “virtual machines” (VM), each with their own tailored set of reserved

partitions. It was first developed in the 1960’s by IBM Corporation in order to partition a large mainframe computer into several logical instances running on one mainframe computer as a host .The main (and only) computer is called a host and multiple Virtual Machines can be created within the host. The VMs live independently of one another and different operating systems and applications can be loaded on each VM. Hypervisors play a significant role as far as resource allocation is concerned. Virtualization
