Illustrated Tutorial: Creating a Bootable USB Flash Drive for Windows XP
Illustrated tutorial: Creating a bootable Version 1.0 February 15, 2007 USB flash drive for Windows XP By Greg Shultz The ability to boot Windows XP from a USB Flash Drive (UFD) offers endless possibilities. For example, you might make an easy-to-use troubleshooting tool for booting and analyzing seemingly dead PCs. Or you could transport your favorite applications back and forth from home to work without having to install them on both PCs. However, before you can create a bootable UFD, you must clear a few hurdles. You saw that one coming didn’t you? The first hurdle is having a PC in which the BIOS will allow you to configure the USB port to act as a bootable device. The second hurdle is having a UFD that that will work as a bootable device and that’s large enough and fast enough to boot an operating system such as Windows XP. The third hurdle is finding a way to condense and install Windows XP on a UFD. If you have a PC that was manufactured in the last several years, chances are that its BIOS will allow you to configure the USB port to act as a bootable device. If you have a good qual- ity UFD that’s at least 512 KB and that was manufactured in the last couple of years, you’ve probably cleared the second hurdle. And once you’ve cleared those first two hur- dles, the third one is a piece of cake. All you have to do is download and run some free soft- ware to create the bootable UFD. -

Page 12.152.1 Page © American Society for Engineering Education, 2007 A Virtual Machine Environment for Real Time Systems Laboratories Abstract The goal of this project was to build a superior environment for a real time system laboratory that would allow users to run Windows and Linux embedded application development tools concurrently on a single computer. These requirements were dictated by real-time system applications which are increasingly being implemented on asymmetric dual-core processors running different operating systems. A real time systems laboratory curriculum based on dual- core architectures has been presented in this forum in the past.2 It was designed for a senior elective course in real time systems at the University of Texas at Tyler that combines lectures along with an integrated lab. -

Understanding Windows 10 – a Guide to Help Get You Started Settings
Understanding Windows 10 – A Guide to Help Get you Started By Jim Hillier – July 14, 2015 https://davescomputertips.com/understanding-windows-10-a-guide-to-help-get-you-started/ Following an initial perusal of Windows 10 it appeared that Microsoft included a lot of changes merely for the sake of change, presumably to help expand the gap between Windows 8 and Windows 10. However, after spending more time working with the new operating system you will realize that statement is incorrect, and here’s why. Settings – The Windows 10 Nerve Center At the very heart of Windows 10 is the ―Settings‖ menu which provides the interface for managing how the operating system displays and behaves. Consequently, a number of previously easily accessible settings/options have been moved into the Settings menus for the sake of centralization. While this may well now force users to dig a little deeper in order to locate a particular setting, I can appreciate the logic behind it, everything in one place, and no fragmentation. Finding “Screen Resolution in Windows 10 For example: Accessing ―Screen Resolution‖ settings has long been a simple matter of selecting the option from the desktop right click menu. Now, in Windows 10, one needs to take a rather more convoluted path: 1. Click Start and then Settings 2. Click System, then click Display(the Display tab should open by default) 3. Click ―Advanced display settings‖ There it is! Adding Desktop Shortcuts to System Locations in Windows 10 This is another setting location that has changed and integrated into the all, encompassing Settings menu. -

The Hypervisor is the one which provides the complete virtualization environment which will intend to virtualize as much as hardware and systems which will include the CPUs, Memory, network interfaces and so on. Because of the virtualization technologies such as the KVM and others such as ESXi, there has been a significant decrease in the usage if the resources and decrease in the costs involved. -
Hypervisors Vs. Lightweight Virtualization: a Performance Comparison
2015 IEEE International Conference on Cloud Engineering Hypervisors vs. Lightweight Virtualization: a Performance Comparison Roberto Morabito, Jimmy Kjällman, and Miika Komu Ericsson Research, NomadicLab Jorvas, Finland [email protected], [email protected], [email protected] Abstract — Virtualization of operating systems provides a container and alternative solutions. The idea is to quantify the common way to run different services in the cloud. Recently, the level of overhead introduced by these platforms and the lightweight virtualization technologies claim to offer superior existing gap compared to a non-virtualized environment. performance. In this paper, we present a detailed performance The remainder of this paper is structured as follows: in comparison of traditional hypervisor based virtualization and Section II, literature review and a brief description of all the new lightweight solutions. In our measurements, we use several technologies and platforms evaluated is provided. The benchmarks tools in order to understand the strengths, methodology used to realize our performance comparison is weaknesses, and anomalies introduced by these different platforms in terms of processing, storage, memory and network. introduced in Section III. The benchmark results are presented Our results show that containers achieve generally better in Section IV. Finally, some concluding remarks and future performance when compared with traditional virtual machines work are provided in Section V. and other recent solutions. Albeit containers offer clearly more dense deployment of virtual machines, the performance II. BACKGROUND AND RELATED WORK difference with other technologies is in many cases relatively small. In this section, we provide an overview of the different technologies included in the performance comparison. -
