of Math and Computer Science, University of Udine, Via delle Scienze 206, 33100 Udine, Italy Abstract Web3D open standards allow the delivery of interactive 3D virtual learning environments through the Internet, reaching potentially large numbers of learners worldwide, at any time. This paper introduces the educational use of virtual reality based on Web3D technologies. After briefly presenting the main Web3D technologies, we summarize the pedagogical basis that motivate their exploitation in the

5.2.5 Modifying Virtual Disks: By starting with the Windows Server 2012 operating system, Hyper-V will be defined within all of us which has the ability to expand or shrink decrease the size of a virtual hard disk while the virtual machine is still under the execution. This concept can create a virtual hard disk (attached to a SCSI Controller), that will add the virtual hard disk to the relevant virtual machine and it will explain the process for expanding and shrinking a virtual hard disk within

Memory Management: Memory management operations are one of the fundamental core components of an operating system. The memory management function is to organize and manage memory hierarchy of the random access memory, bulky address spaces, memory mapping, manage alternate memory devices, physical allocation, de-allocation of processes, and the computer’s hard drive. Physical address is the address perceived by the memory unit. Virtual memory is the necessity of memory by exploiting the hard drive

Memory Management Memory management is an important core part to any operating system. The basic function is to manage the RAM and hard disks on a computer. The tasks include allocating the memory and processes taking care of logistics and implementation of the virtual memory. It does this by utilizing the hard disks memory as more RAM. Optimization of the memory affects the overall performance and speed of the computer system. Windows uses an executive component known as Virtual Memory Manager

The 32-bits of address space converts into the 4GB of virtual memory. The 4GB is the amount that can be accessed by a process. The Windows operating system has Kernel-mode and User-mode memory ("Memory Management 101", 2007). If you exceed

PFCH DC Unification Project UNIX and Linux Advantages UNIX has been the cornerstone for infrastructure for the past decade with popular flavors such as Solaris (Craig, 2012). UNIX is a proprietary brand typically run in large organizational infrastructure. However, many of the UNIX variants are open source that allow users to customize their distribution as they see fit and making copies to install in an unlimited number of machines. UNIX offers a highly stable operating system (OS) that is ideal
