Question

1. Discuss some of the technical and nontechnical issues that might come up in trying to establish a large grid computing project such as the World Computing Grid. 2. How does Microsoft envision the future for Windows 10? Do you support this vision? Why or why not? 3. You have been asked to develop a user interface for a person with limited sight—someone without the ability to recognize letters or shapes on a computer screen. Describe the user interface you would recommend

Answer 1

1. issues that might come up in trying to establish a large grid computing project.

Grid follows the challenges that need to be resolved to harness the full power of grid:-

(A) Limited Area & Applications:-Grid computing is used to solve for large and complex problems. Its area is limited such as scientists, developer, analysis and researchers. Grid computing is used in Hollywood flickers, industrial research, and biometric research and engineering research. A grid cannot use for common problems by common persons.

(B) Management and Administration: - Many institutes and organizations used grid computing. It distributes the resources on large geographically distributed environments and accesses the heterogeneous devices and machines. So it is a major challenge to manage the administration of grid computing.

(C)Lack of grid-enabled software: - The software, which is enabled the grid computing is less, It has limited software on Grid. Much software has no copyright issues and source code of the license. It is needed for more company developing grid-enabled version, need more developers on grid development and need to develop open-source software.

(D)Distributed computing Vs Grid computing: - Grid computing involves dynamic virtual organization, resource sharing and peer to peer computing. The Grid intends to make access to computing power, scientific data repositories and experimental facilities as easy as the Web makes access to information. Same all facilities provide grid computing. So it is a challenge for grid computing.

2 Microsoft's latest Windows 10 preview offers up a good look at what the company is planning for the future of laptops and PCs. While Windows 8 was never received well by consumers or businesses, Windows 10 aims to make things a lot more familiar. We saw the new Start Menu when Microsoft released its first Windows 10 preview back in October, but things are changing rapidly. There's more built-in apps, user interface changes, and a whole new touch mode designed for 2-in-1 laptops and tablets.

Windows 10 is still a work in progress, but Microsoft is soliciting feedback and changing parts of its operating system before it ships later this year. While the company demonstrated a number of new features and apps during its Windows 10 event last week, not everything is in preview straight away. A number of new apps will debut in the coming months, and Microsoft plans to more rapidly roll out new builds of Windows 10 to testers.

Until then, let's take a look at what's new in the second major Windows 10 preview

To deliver impressive GUIs, remember – users are humans, with needs such as comfort and low cognitive loads. Follow these guidelines:

1. Make elements such as buttons and other common elements perform predictably (including responses such as pinch = zoom) so users can unconsciously use them everywhere. Form should follow function.
2. Maintain high discoverability. Clearly label icons and include well-indicated affordances.
3. Keep interfaces simple and create an “invisible” feel. Every element must serve a purpose.
4. Respect the user’s eye and attention regarding layout; focus on hierarchy and readability:
   • Alignment – minimize your number of alignment lines (think justified text); typically choose edge (over center) alignment.
   • Draw attention to key features using:
     • Color, brightness and contrast. Avoid including colors or buttons excessively.
     • Text via font sizes, bold type/weighting, italics, capitals and distance between letters. Users should pick up meanings just by scanning.
5. Minimize the number of actions for performing tasks but focus on one chief function per page; guide users by indicating preferred actions. Ease complex tasks by using progressive disclosure.
6. Put controls near objects users want to control.
7. Keep users informed vis-à-vis system responses/actions with feedback.
8. Consider defaults to reduce user burdens (e.g., pre-fill forms).
9. Use reusable design patterns to guide behavior regarding navigation and search functions.
10. Concentrate on maintaining brand consistency.
