  • laptop is a personal computer designed for mobile use that is small and light enough for a person to rest on their lap.
  • As the personal computer became feasible in the early 1970s, the idea of a portable personal computer followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968,[2] and described in his 1972 paper as the "Dynabook".[3]
  • The IBM SCAMP project (Special Computer APL Machine Portable), was demonstrated in 1973. This prototype was based on the PALM processor (Put All Logic In Microcode). The IBM 5100, the first commercially available portable computer, appeared in September 1975, and was based on the SCAMP prototype.[4] As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The Osborne 1, released in 1981, used the Zilog Z80 and weighed 23.6 pounds (10.7 kg). It had no battery, a 5 in (13 cm) CRT screen, and dual 5.25 in (13.3 cm) single-density floppy drives. In the same year the first laptop-sized portable computer, the Epson HX-20, was announced.[5] The Epson had a LCD screen, a rechargeable battery, and a calculator-size printer in a 1.6 kg (3.5 lb) chassis. Both Tandy/RadioShack and HP also produced portable computers of varying designs during this period.[6][7] The first laptops using the flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The $8,150 ($18,370 in current dollar terms) GRiD Compass 1100, released in 1982, was used at NASA and by the military among others. The Gavilan SC, released in 1983, was the first computer described as a "laptop" by its manufacturer[8] From 1983 onward, several new input techniques were developed and included in laptops, including the touchpad (Gavilan SC, 1983), the pointing stick (IBM ThinkPad 700, 1992) and handwriting recognition (Linus Write-Top,[9] 1987). Some CPUs, such as the 1990 Intel i386SL, were designed to use minimum power to increase battery life of portable computers, and were supported by dynamic power management features such as Intel SpeedStep and AMD PowerNow! in some designs. Displays reached VGA resolution by 1988 (Compaq SLT/286), and color screens started becoming a common upgrade in 1991 with increases in resolution and screen size occurring frequently until the introduction of 17"-screen laptops in 2003. Hard drives started to be used in portables, encouraged by the introduction of 3.5" drives in the late 1980s, and became common in laptops starting with the introduction of 2.5" and smaller drives around 1990; capacities have typically lagged behind physically larger desktop drives. Optical storage, read-only CD-ROM followed by writeable CD and later read-only or writeable DVD and Blu-Ray, became common in laptops soon in the 2000s.

  • A mobile phone (also called mobile, cellular phone, cell phone or handphone)[1] is an electronic device used for full duplex two-way radio telecommunications over a cellular network of base stations known as cell sites. Mobile phones differ from cordless telephones, which only offer telephone service within limited range through a single base station attached to a fixed land line, for example within a home or an office.
  • In addition to being a telephone, modern mobile phones also support many additional services, and accessories, such as SMS (or text) messages, e-mail, Internet access, gaming, Bluetooth and infrared short range wireless communication, camera, MMS messaging, MP3 player, radio and GPS. Low-end mobile phones are often referred to as feature phones, whereas high-end mobile phones that offer more advanced computing ability are referred to as smartphones.
  • A mobile phone (also called mobile, cellular telephone, or cell phone) is an electronic device used to make mobile telephone calls across a wide geographic area.

    "A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device which can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile network operator. The calls are to and from the public telephone network which includes other mobiles and fixed-line phones across the world. By contrast, a cordless telephone is used only within the short range of a single, private base station. In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these more general computing capabilities are referred to as smartphones. The first hand-held mobile phone was demonstrated by Dr Martin Cooper of Motorola in 1973, using a handset weighing 2 1/2 lbs (about 1 kg).[1] In 1983, the DynaTAC 8000x was the first to be commercially available. In the twenty years from 1990 to 2010, worldwide mobile phone subscriptions grew from 12.4 million to over 4.6 billion, penetrating the developing economies and reaching the bottom of the economic pyramid"

  • The term Web 2.0 is commonly associated with web applications that facilitate interactive information sharing, interoperability, user-centered design,[1] and collaboration on the World Wide Web. A Web 2.0 site gives its users the free choice to interact or collaborate with each other in a social media dialogue as creators (prosumer) of user-generated content in a virtual community, in contrast to websites where users (consumer) are limited to the passive viewing of content that was created for them. Examples of Web 2.0 include social-networking sites, blogs, wikis, video-sharing sites, hosted services, web applications, mashups and folksonomies.

  • Voice over Internet Protocol (VoIP, Voice over IP) is a general term for a family of methodologies, communication protocols, and transmission technologies for delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone. Internet telephony refers to communications services — voice, facsimile, and/or voice-messaging applications — that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.[1] VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream. Codec use is varied between different implementations of VoIP (and often a range of codecs are used); some implementations rely on narrowband and compressed speech, while others support high fidelity stereo codecs.

  • The World Is Flat: A Brief History of the Twenty-First Century is an international bestselling book by Thomas L. Friedman that analyzes globalization,
  • #1: Collapse of Berlin Wall--11/9/89: The event not only symbolized the end of the Cold War, it allowed people from other side of the wall to join the economic mainstream. #2: Netscape--8/9/95: Netscape and the Web broadened the audience for the Internet from its roots as a communications medium used primarily by 'early adopters and geeks' to something that made the Internet accessible to everyone from five-year-olds to ninety-five-year olds. The digitization that took place meant that everyday occurrences such as words, files, films, music and pictures could be accessed and manipulated on a computer screen by all people across the world. #3: Workflow software: The ability of machines to talk to other machines with no humans involved was stated by Friedman. Friedman believes these first three forces have become a "crude foundation of a whole new global platform for collaboration." #4: Uploading: Communities uploading and collaborating on online projects. Examples include open source software, blogs, and Wikipedia. Friedman considers the phenomenon "the most disruptive force of all." #5: Outsourcing: Friedman argues that outsourcing has allowed companies to split service and manufacturing activities into components which can be subcontracted and performed in the most efficient, cost-effective way. This process became easier with the mass distribution of fiber optic cables during the introduction of the World Wide Web. #6: Offshoring: The internal relocation of a company's manufacturing or other processes to a foreign land to take advantage of less costly operations there. China's entrance in the WTO allowed for greater competition in the playing field. Now countries such as Malaysia, Mexico, Brazil must compete against China and each other to have businesses offshore to them. #7: Supply-chaining: Friedman compares the modern retail supply chain to a river, and points to Wal-Mart as the best example of a company using technology to streamline item sales, distribution, and shipping. #8: Insourcing: Friedman uses UPS as a prime example for insourcing, in which the company's employees perform services--beyond shipping--for another company. For example, UPS repairs Toshiba computers on behalf of Toshiba. The work is done at the UPS hub, by UPS employees. #9: In-forming: Google and other search engines are the prime example. "Never before in the history of the planet have so many people-on their own-had the ability to find so much information about so many things and about so many other people", writes Friedman. The growth of search engines is tremendous; for example take Google, in which Friedman states that it is "now processing roughly one billion searches per day, up from 150 million just three years ago". #10: "The Steroids": Personal digital devices like mobile phones, iPods, personal digital assistants, instant messaging, and voice over Internet Protocol (VoIP).

  • The National Center for Supercomputing Applications (NCSA) is a state-federal partnership to develop and deploy national-scale cyberinfrastructure that advances science and engineering. NCSA operates as a unit of the University of Illinois at Urbana-Champaign but it provides high-performance computing resources to researchers across the country. Support for NCSA comes from the National Science Foundation, the state of Illinois, the University of Illinois, business and industry partners, and other federal agencies.
  • These centers were founded when a group of University of Illinois faculty, led by Larry Smarr, sent an unsolicited proposal to the National Science Foundation in 1983. The foundation announced funding for the supercomputer centers in 1985; the first supercomputer at NCSA came online in January 1986.
  • NCSA provides leading-edge computing, data storage, and visualization resources. NCSA computational and data environment implements a multi-architecture hardware strategy, deploying both clusters and shared memory systems to support high-end users and communities on the architectures best-suited to their requirements. Nearly 1,360 scientists, engineers and students used the computing and data systems at NCSA to support research in more than 830 projects. A list of NCSA hardware is available at NCSA Capabilities

  • Today NCSA is collaborating with IBM, under a grant from the National Science Foundation, to build [1] "Blue Waters," a supercomputer capable of performing 1 quadrillion calculations per second, a measure known as a petaflop. Blue Waters is due to come online in 2011.
  • The Mosaic web browser, the first popular graphical Web browser which played an important part in expanding the growth of the World Wide Web, was written by Marc Andreessen and Eric Bina at NCSA. Andreessen and Bina went on to develop the Netscape Web browser. Mosaic was later licensed to Spyglass,_Inc. which provided the foundation for Internet Explorer.
  • Initially, NCSA's administrative offices were in the Water Resources Building and employees were scattered across the campus. NCSA is now headquartered within its own building directly north of the Siebel Center for Computer Science, on the site of a former baseball field, Illini Field. NCSA's supercomputers remain at the Advanced Computation Building, but construction is now under way on a Petascale Computing Facility to house Blue Waters.

  • Radio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader. Radio-frequency identification involves interrogators (also known as readers), and tags (also known as labels). Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal. There are generally three types of RFID tags: active RFID tags, which contain a battery and can transmit signals autonomously, passive RFID tags, which have no battery and require an external source to provoke signal transmission, and battery assisted passive (BAP) RFID tags, which require an external source to wake up but have significant higher forward link capability providing greater range. There are a variety of groups defining standards and regulating the use of RFID, including: International Organization for Standardization (ISO), International Electrotechnical Commission (IEC), ASTM International, DASH7 Alliance, EPCglobal. (Refer to Regulation and standardization below.) RFID has many applications; for example, it is used in enterprise supply chain management to improve the efficiency of inventory tracking and management. Contents [hide]

Radio-frequency identification involves interrogators (also known as readers), and tags (also known as labels). Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal. There are generally three types of RFID tags: active RFID tags, which contain a battery and can transmit signals autonomously, passive RFID tags, which have no battery and require an external source to provoke signal transmission, and battery assisted passive (BAP) RFID tags, which require an external source to wake up but have significant higher forward link capability providing greater range. There are a variety of groups defining standards and regulating the use of RFID, including: International Organization for Standardization (ISO), International Electrotechnical Commission (IEC), ASTM International, DASH7 Alliance, EPCglobal. (Refer to Regulation and standardization below.) RFID has many applications; for example, it is used in enterprise supply chain management to improve the efficiency of inventory tracking and management.

  • Mosaic is the web browser credited with popularizing the World Wide Web. It was also a client for earlier protocols such as FTP, NNTP, and gopher. Its clean, easily understood user interface, reliability, Windows port and simple installation all contributed to making it the application that opened up the Web to the general public.[2] Mosaic was also the first browser to display images inline with text instead of displaying images in a separate window.[3] While often described as the first graphical web browser, Mosaic was preceded by the lesser-known Erwise[4] and ViolaWWW.
