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. -

Implementing Tablet Computers for Investigators at the Pinellas County Sheriff’S Office
Implementing Tablet Computers for Investigators at the Pinellas County Sheriff’s Office Jim Main Abstract With the exception of a few specialized fields, like cybercrimes, most law enforcement investigators do the majority of their crime solving in the field. Research was conducted to see what other government agencies are doing to make their investigators more efficient in the field. Surveys were conducted with the detectives with the Pinellas County Sheriff’s Office to see what their views are in using tablet computers in the field. The findings of this research show that tablet computers should be implemented in several of the sections for use by the detectives in the field. Introduction Over the past several years, tablet computers have become very prevalent in society. With entry models priced in the range of just a couple hundred of dollars, they have become very affordable to the average person. In 2012, more tablets were sold than laptop computers and by 2014, one in five United States consumers will own a tablet (Horton, 2011). Like civilians, many law enforcement employees have acquired tablet computers. Because tablets can be used for much more than just checking email or browsing the web, law enforcement employees are starting to consider ways that tablets can be used for improving their performance at work. Detectives in the Knox County (Tennessee) Sheriff’s Office Major Crimes and Family Crisis units began using tablets after a detective bought one for personal use and found it useful on the job. One example of how a tablet is useful in law enforcement is when interviewing a witness to a crime involving a car, the tablet has been used to show photos of particular cars to the witness to more accurately report the correct information (Nadeau, 2001). -

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. -
Good Reasons to Use a Desktop Computer
Good reasons to use a desktop computer Why would anyone possibly need a desktop? For most, it goes against all common sense to use a desktop because they're not as convenient and portable as a lap- top, and a laptop does what you need it to do just fine. At the same time, the good ol' bulky, stationary desktop still has a place for many people. Here are good reasons why you might want to use desktop computer. You can upgrade the parts, which is cheaper than buying a new laptop. When a laptop starts to slow down, your only option is to buy a whole new one. Depending on what you need a com- puter for, a new laptop could cost thousands of dollars. That's because you have to buy every single part inside the laptop brand new — the processor, motherboard, RAM, hard drive, and everything else. But most of the parts in your old laptop are probably still fine, and it's usually only the processor (and the motherboard it sits on) that needs upgrading. With a desktop you can easily replace an aging processor (and motherboard) for around $300. That said, all-in-one desktops like the iMac can be a little difficult to upgrade. You get more bang for your buck. Depending on the brand, desktops and laptops with similar specs can often cost the same. Yet, the main differences between the two are the processor and the graphics processor. Most Laptops use the smaller mobile version of a processor model, which often aren't quite as powerful as the full-size desktop versions. -
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. -
Today Computers Are All Around Us. from Desktop Computers To
Today computers are all around us. From desktop computers to smartphones, they're changing the way that we live our lives. But have you ever asked yourself what exactly is a computer? A computer is an electronic device that manipulates information or data. The computer sees data as ones and zeros but it knows how to combine them into more complex things such as a photograph, a movie, a website, a game and much more... Computers use a combination of hardware and software. Hardware is any physical part of the computer which includes all of the internal components and also the external parts like the monitor and keyboard. Software is any set of instructions that tells the hardware what to do such as a web browser, media player or word processor. Now when most people say computer, they're talking about a personal computer. This can be a desktop computer or a laptop computer which has basically the same capabilities but in a more portable package. Personal computers come in two main styles, PC and Mac. PCs are the most common types, there are many different companies that make them and they usually come with the Microsoft Windows operating system. Macs or Macintosh computers are all made by one company, Apple, and they come with the Mac OS 10 operating system. Computers come in many other shapes and sizes, mobile phones, tablets, game consoles and even TVs have built-in computers, although they may not do everything a desktop or laptop can. There is another type of computer that plays an important role in our lives, servers. -

Classification of Computers
Chapter-2 Classification of Computers Computers can be classified many different ways -- by size, by function, or by processing capacity. Functionality wise 4 types a) Micro computer b) Mini Computer c) Mainframe Computer d) Super Computer Microcomputers Microcomputers are connected to networks of other computers. The price of a microcomputer varies from each other depending on the capacity and features of the computer. Microcomputers make up the vast majority of computers. Single user can interact with this computer at a time. It is a small and general purpose computer. Mini Computer Mini Computer is a small and general purpose computer. It is more expensive than a micro computer. It has more storage capacity and speed. It designed to simultaneously handle the needs of multiple users. Mainframe Computer Large computers are called Mainframes. Mainframe computers process data at very high rates of speed, measured in the millions of instructions per second. They are very expensive than micro computer and mini computer. Mainframes are designed for multiple users and process vast amounts of data quickly. Examples: - Banks, insurance companies, manufacturers, mail-order companies, and airlines are typical users. Super Computers The largest computers are Super Computers. They are the most powerful, the most expensive, and the fastest. They are capable of processing trillions of instructions per second. It uses governmental agencies, such as:- Chemical analysis in laboratory Space exploration National Defense Agency National Weather Service Bio-Medical research Design of many other machines Limitations of Computer Computer cannot take over all activities simply because they are less flexible than humans. It does not hold intelligence of its own. -
