4: Gigabit Research
Gigabit Research 4 s was discussed in chapter 3, the limitations of current networks and advances in computer technology led to new ideas for applications and broadband network design. This in turn led to hardware and software developmentA for switches, computers, and other network compo- nents required for advanced networks. This chapter describes some of the research programs that are focusing on the next step-the development of test networks.1 This task presents a difficult challenge, but it is hoped that the test networks will answer important research questions, provide experience with the construction of high-speed networks, and demonstrate their utility. Several “testbeds” are being funded as part of the National Research and Education Network (NREN) initiative by the Advanced Research Projects Agency (ARPA) and the National Science Foundation (NSF). The testbed concept was first proposed to NSF in 1987 by the nonprofit Corporation for National Research Initiatives (CNRI). CNRI was then awarded a planning grant, and solicited proposals or white papers" from The HPCC prospective testbed participants. A subsequent proposal was then reviewed by NSF with a focus on funding levels, research program’s six objectives, and the composition of the testbeds. The project, cofunded by ARPA and NSF under a cooperative agreement with testbeds will CNRI, began in 1990 and originally covered a 3-year research program. The program has now been extended by an additional demonstrate fifteen months, through the end of 1994.

The Portable Computing Quest
Chapter 1 The Portable Computing Quest In This Chapter ▶ Understanding portable computing ▶ Reviewing laptop history ▶ Recognizing the Tablet PC variation ▶ Getting to know the netbook ▶ Deciding whether you need a laptop figure, sometime a long time ago, one early proto-nerd had an idea. IWearing his thick glasses and a white lab coat, he stared at the large, vacuum tube monster he was tending. He wondered what it would be like to put wheels on the six-ton beast. What if they could wheel it outside and work in the sun? It was a crazy idea, yet it was the spark of a desire. Today that spark has flared into a full-blown portable computing industry. The result is the laptop, Tablet PC, or netbook computer you have in your lap, or which your lap is longing for. It’s been a long road — this chapter tells you about the journey by explaining the history of the portable computing quest. Laptop History You can’t make something portable simply by bolting a handle to it. Sure, it pleasesCOPYRIGHTED the marketing folk who understand MATERIAL that portability is a desirable trait: Put a handle on that 25-pound microwave oven and it’s suddenly “por- table.” You could put a handle on a hippopotamus and call it portable, but the thing already has legs, so what’s the point? My point is that true portability implies that a gizmo has at least these three characteristics: ✓ Lightweight ✓ No power cord ✓ Practical 005_578292-ch01.indd5_578292-ch01.indd 7 112/23/092/23/09 99:11:11 PPMM 8 Part I: The Laptop Shall Set You Free The ancient portable computer Long before people marveled over (solar pow- kids now learn to use the abacus in elementary ered) credit-card-size calculators, there existed school. -

The following is a brief overview of the differences between standard desktops and workstations as well as the implications for overall performance and productivity as compiled from the editorial resources of CNET, TechRepublic and ZDNet.com. Think Inside the Box A lot of people tend to think of desktop computers and computer workstation as one and the same but that isn’t always the case in terms of power and performance. In fact, many of today’s most demanding workloads and applications for industries such as engineering, entertainment, finance, manufacturing, and science actually require much higher functionality than what traditional desktops have to offer. -
The Video Game Industry an Industry Analysis, from a VC Perspective
The Video Game Industry An Industry Analysis, from a VC Perspective Nik Shah T’05 MBA Fellows Project March 11, 2005 Hanover, NH The Video Game Industry An Industry Analysis, from a VC Perspective Authors: Nik Shah • The video game industry is poised for significant growth, but [email protected] many sectors have already matured. Video games are a large and Tuck Class of 2005 growing market. However, within it, there are only selected portions that contain venture capital investment opportunities. Our analysis Charles Haigh [email protected] highlights these sectors, which are interesting for reasons including Tuck Class of 2005 significant technological change, high growth rates, new product development and lack of a clear market leader. • The opportunity lies in non-core products and services. We believe that the core hardware and game software markets are fairly mature and require intensive capital investment and strong technology knowledge for success. The best markets for investment are those that provide valuable new products and services to game developers, publishers and gamers themselves. These are the areas that will build out the industry as it undergoes significant growth. A Quick Snapshot of Our Identified Areas of Interest • Online Games and Platforms. Few online games have historically been venture funded and most are subject to the same “hit or miss” market adoption as console games, but as this segment grows, an opportunity for leading technology publishers and platforms will emerge. New developers will use these technologies to enable the faster and cheaper production of online games. The developers of new online games also present an opportunity as new methods of gameplay and game genres are explored. -

TAXONOMY for MOBILE TERMINALS a Selective Classification Scheme

Abstract: There is a great number of different types of mobile computing devices like cellular phones, Handhelds and notebooks. However in literature so far there is no common accepted definition for these terminal types. Es- pecially the term “Smartphone” is used for very different types of mobile phones. In our article we therefore propose a comprehensive taxonomy for mobile terminals that clearly distinguishes between different classes of terminals. 1 MOBILE TERMINALS is that mobile computing is a rather new technology so a market consolidation like that for personal desk- Everyday life without mobile terminals is almost top computers didn't take place yet.
