Motorola MicroTAC
The Motorola MicroTAC is a cellular phone first manufactured as an analog version in 1989. GSM-compatible and TDMA/Dual-Mode versions were introduced in 1994. The MicroTAC introduced a new "flip" design, where the "mouthpiece" folded over the keypad, although on later production the "mouthpiece" was actually located in the base of the phone, along with the ringer. This set the standard and became the model for modern flip phones today. Its predecessor was the much larger Motorola DynaTAC and it was succeeded by the Motorola StarTAC in 1996. "TAC" was an abbreviation of "Total Area Coverage" in all three models. Model history MicroTAC 9800X The MicroTAC, released by Motorola on April 25, 1989, was the smallest and lightest phone available at the time. Upon its release, it made headlines across the world. The phone was released as the "MicroTAC Pocket Cellular Telephone." The first MicroTACs were known as the Motorola 9800X, a continuation of the numerical name Motorola gave ...

Jaguar XK8
The Jaguar XK8 (project code X100) is a grand tourer launched by Jaguar Cars in 1996, and was the first generation of a new XK series. The XK8 was available in two-door coupé or two-door convertible body styles with the new 4.0-litre Jaguar AJ-V8 engine. In 1998, the XKR was introduced with a supercharged version of the engine. In 2003, the engines were replaced by the new 4.2-litre AJ34 engines in both the naturally aspirated and supercharged variations. The first-generation of the XK series shares its XJS-derived platform with the Aston Martin DB7, with both cars tracing their history back to an abandoned Jaguar development study in the mid-1980s known as XJ41/XJ42, which had been mooted to be known as the F-Type. One of the revisions is the use of the second generation of Jaguar's independent rear suspension unit, taken from the Jaguar XJ (XJ40). Development began in 1992, with design work starting earlier in late 1991. By October 1992 a design was chosen and later froz ...

MicroDigital
Microdigital Eletrônica Ltda. was an influential Brazilian computer company in the 1980s, based in São Paulo. History Established in 1981 by the brothers George and Tomas Kovari (whose initials were the TK of the domestic computers line made by the company), its first product was the ''TK80'', a clone of the British microcomputer Sinclair ZX80. The company reached its height around 1985, with the launching of the TK90X (clone of the ZX Spectrum) and the ''TK-2000 II'', a personal computer partially compatible (at Applesoft BASIC level) with the Apple II+. At this time, it had approximately 400 employees in three plants (two in São Paulo and one in the Zona Franca de Manaus) and more than 700 peddlers spread for all Brazil. Although the logo of the company is identical to the earlier Microdigital Ltd of the United Kingdom the company is not related.

Madeleine Albright
Madeleine Jana Korbel Albright (born Marie Jana Korbelová; May 15, 1937 – March 23, 2022) was an American diplomat and political scientist who served as the 64th United States secretary of state from 1997 to 2001. A member of the Democratic Party, Albright was the first woman to hold that post. Born in Prague, Czechoslovakia, Albright immigrated to the United States after the 1948 communist coup d'état when she was eleven years old. Her father, diplomat Josef Korbel, settled the family in Denver, Colorado, and she became a U.S. citizen in 1957. Albright graduated from Wellesley College in 1959 and earned a PhD from Columbia University in 1975, writing her thesis on the Prague Spring. She worked as an aide to Senator Edmund Muskie from 1976 to 1978, before serving as a staff member on the National Security Council under Zbigniew Brzezinski. She served in that position until 1981, when President Jimmy Carter left office. After leaving the National Security Council, Alb ...

United States Secretary Of State
The United States secretary of state is a member of the executive branch of the federal government of the United States and the head of the U.S. Department of State. The office holder is one of the highest ranking members of the president's Cabinet, and ranks the first in the U.S. presidential line of succession among Cabinet secretaries. Created in 1789 with Thomas Jefferson as its first office holder, the secretary of state represents the United States to foreign countries, and is therefore considered analogous to a foreign minister in other countries. The secretary of state is nominated by the president of the United States and, following a confirmation hearing before the Senate Committee on Foreign Relations, is confirmed by the United States Senate. The secretary of state, along with the secretary of the treasury, secretary of defense, and attorney general, are generally regarded as the four most crucial Cabinet members because of the importance of their respective depa ...

StarTAC
The Motorola StarTAC, first released on January 3, 1996, is often assumed to be the first ever clamshell (flip) mobile phone. Technically, however, NEC had been releasing flip phones on NTT Docomo's PDC Mova network long before 1996, namely the TZ-804 and TZ-1501, both respectively launched in 1991 and late 1994. Another early precursor of this form factor was the Grillo, which was designed in Italy by Richard Sapper and Marco Zanuso in 1965. The StarTAC is the successor of the MicroTAC, a semi-clamshell design first launched in 1989. Whereas the MicroTAC's flip folded down from below the keypad, the StarTAC folded up from above the display. In 2005, '' PC World'' named the StarTAC as the ''6th Greatest Gadget of the Past 50 Years'' (out of a list of fifty). The StarTAC was among the first mobile phones to gain widespread consumer adoption; approximately 60 million StarTACs were sold. The StarTAC brand was revived in 2004 and 2007 for a series of flip phones exclusive to some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CDMA
Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference between the users, CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range. It is used as the access method in many mobile phone standards. IS-95, also called "cdmaOne", and its 3G evolution CDMA2000, are often simply referred to as "CDMA", but UMTS, the 3G standard used by GSM carriers, also uses "wideband CDMA", or W-CDMA, as well as TD-CDMA and TD-SCDMA, as its radio technologies. It can be also used as a channe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Telephony
Telephony ( ) is the field of technology involving the development, application, and deployment of telecommunication services for the purpose of electronic transmission of voice, fax, or data, between distant parties. The history of telephony is intimately linked to the invention and development of the telephone. Telephony is commonly referred to as the construction or operation of telephones and telephonic systems and as a system of telecommunications in which telephonic equipment is employed in the transmission of speech or other sound between points, with or without the use of wires. The term is also used frequently to refer to computer hardware, software, and computer network systems, that perform functions traditionally performed by telephone equipment. In this context the technology is specifically referred to as Internet telephony, or voice over Internet Protocol (VoIP). Overview The first telephones were connected directly in pairs. Each user had a separate telephone wired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
