For example, E-learning, cloud computing, social networking, virtual laboratories, virtual realities, virtual worlds, massive open online courses (MOOCs), and bring your own device (BYOD) are all new concepts of immersive and global education that have emerged in educational literature. One of the greatest challenges presented to e-learning solutions is the reproduction of the benefits of an educational institution’s physical laboratory. For a university without a computing lab, to obtain hands-on IT training with software, operating systems, networks, servers, storage, and cloud computing similar to that which could be received on a university campus computing lab, it is necessary to use a combination of technological tools. Such teaching tools must promote the transmission of knowledge, encourage interaction and collaboration, and ensure students obtain valuable hands-on experience.

  • Oracle Virtualbox Installation, Setup, and Ubuntu Introduction
    ORACLE VIRTUALBOX INSTALLATION, SETUP, AND UBUNTU INTRODUCTION • VirtualBox is a hardware virtualization program. • Create virtual computers aka virtual machines. • Prototyping, sandboxing, testing. • The computer that VirtualBox is installed on is called the “host”, and each virtual machine is called a “guest”. PREREQUISITES Since virtual machines share resources with the host computer, we need to know what resources we have available on our host. • Click “Type here to search”. • Search for “System Information”. • Note the number of processor cores and the amount of RAM installed in your host. PREREQUISITES • Expand “Components”. • Expand “Storage”. • Select “Drives”. • Note the amount of free space available on your host. Every computer is different, so how we will need to balance these resources between our host and guest systems will differ. DOWNLOADING VIRTUALBOX • VISIT VIRTUALBOX.ORG • SELECT THE CORRECT PACKAGE • CLICK THE DOWNLOAD LINK. FOR YOUR HOST. INSTALLING VIRTUALBOX • Browse to where you downloaded VirtualBox and run the installer. • All default options will be fine. Simply follow the prompts. INSTALLING VIRTUALBOX • CLICK “FINISH”. • VIRTUALBOX INSTALLED! SETTING THINGS UP Before we build our first virtual machine, we need to download an operating system to install as our “guest”. • Visit Ubuntu.com • Click “Download”. • Select the current Ubuntu Desktop “LTS” release. • LTS releases focus on stability rather than cutting edge features. SETTING THINGS UP • IN VIRTUALBOX, CLICK “NEW”. • NAME THE VIRTUAL MACHINE. SETTING THINGS UP Here’s where we will need the system resources information that we looked up earlier. Each virtual machine functions like a separate computer in and of itself and will need to share RAM with the host.
