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]

NTT Docomo, Inc.[1] (株式会社エヌ・ティ・ティ・ドコモ, Kabushiki Gaisha Enu Ti Ti Dokomo?, TYO: 9437, NYSE: DCM, LSE: NDCM) is the predominant mobile phone operator in Japan. The name is officially an abbreviation of the phrase, "do communications over the mobile network", and is also from a compound word dokomo, meaning "everywhere" in Japanese. Docomo provides phone, video phone (FOMA and Some PHS), i-mode (internet), and mail (i-mode mail, Short Mail, and SMS) services. The company has its headquarters in the Sanno Park Tower, Nagatachō, Chiyoda, Tokyo.[2] Docomo was spun off from Nippon Telegraph and Telephone (NTT) in August 1991 to take over the mobile cellular operations. It provides 2G (mova) PDC cellular services on the 800 MHz band, and 3G FOMA W-CDMA services on the 2 GHz (UMTS2100) and 800 MHz(UMTS800(Band VI)) and 1800 MHz(UMTS1800(Band IX)) bands. Its businesses also included PHS (Paldio), paging, and satellite. Docomo ceased offering a PHS service on January 7, 2008.

Bing (formerly Live Search, Windows Live Search, and MSN Search) is the current web search engine (advertised as a "decision engine")[2] from Microsoft. Bing was unveiled by Microsoft CEO Steve Ballmer on May 28, 2009 at the All Things Digital conference in San Diego. It went fully online on June 3, 2009,[3] with a preview version released on June 1, 2009.

Eric Emerson Schmidt (born April 27, 1955(1955-04-27))[3] is an engineer, Chairman/CEO of Google and a former member of the Board of Directors of Apple Inc.[4] He is the author of the lex lexical analyzer software for Unix. He has also sat on the boards of trustees for Carnegie Mellon University[5] and Princeton University.[6]

Schmidt was born in Washington, D.C. After graduating from Yorktown High School,[7] Schmidt attended Princeton University where he earned a BSEE in 1976.[8] At the University of California, Berkeley, he earned an MS in 1979 for designing and implementing a network linking the campus computer center, the CS and the EECS departments,[9][10] and a PhD in 1982 in EECS with a dissertation about the problems of managing distributed software development and tools for solving these problems.[11] He was joint author of lex (a lexical analyzer and an important tool for compiler construction). He taught at Stanford Business School as a part time professor.[12] He lives in Atherton, California, with his wife Wendy.[13] He is also on the list of ARTnews 200 top art collectors.[14]

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.
