RAZR V9
The Motorola Razr2, stylized as Motorola RAZR2, is a clamshell mobile phone designed and developed by Motorola, announced on May 16, 2007. The Razr2 is the second-generation Razr, succeeding the Motorola Razr V3 and its derivatives and also the Motorola Razr Maxx V6. The Razr2 was released in 2G EDGE (model no. V8), 3G HSDPA (V9) and 3G EV-DO (V9m) variants. The most prominent feature in the Razr2 is the large external display with touch-sensitive buttons and haptic feedback. It allows users to use some functions of the phone without opening up the flip. Compared to the previous Razrs, Razr2 also has Motorola's CrystalTalk technology to improve call quality and help reduce background noise. While the Razr2 V9 and V9m run on Motorola's previous software platform called P2K (based on Versatile Real-Time Executive), the Razr2 V8 runs MotoMagx, based on the MontaVista Linux OS. Release and versions The GSM version of the Razr2, the Motorola Razr2 V8, was released in July 2007 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola
Motorola, Inc. () was an American multinational telecommunications company based in Schaumburg, Illinois. It was founded by brothers Paul and Joseph Galvin in 1928 and had been named Motorola since 1947. Many of Motorola's products had been radio-related communication equipment such as two-way radios, consumer walkie-talkies, cellular infrastructure, mobile phones, satellite communicators, pagers, as well as cable modems and semiconductors. After having lost $4.3 billion from 2007 to 2009, Motorola was split into two independent public companies: Motorola Solutions (its legal successor) and Motorola Mobility (spun off), on January 4, 2011. Motorola designed and sold wireless network equipment such as cellular transmission base stations and signal amplifiers. Its business and government customers consisted mainly of wireless voice and broadband systems (used to build private networks), and public safety communications systems like Astro and Dimetra.

Linux OS
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses and recommends the name "GNU/Linux" to emphasize the use and import ...

Thin-film Transistor
A thin-film transistor (TFT) is a special type of field-effect transistor (FET) where the transistor is made by thin film deposition. TFTs are grown on a supporting (but non-conducting) substrate, such as glass. This differs from the conventional bulk metal-oxide-semiconductor field-effect transistor (MOSFET), where the semiconductor material typically ''is'' the substrate, such as a silicon wafer. The traditional application of TFTs is in TFT liquid-crystal displays. Design and manufacture TFTs can be fabricated with a wide variety of semiconductor materials. Because it is naturally abundant and well understood, amorphous or polycrystalline silicon were (and still are) used as the semiconductor layer. However, because of the low mobility of amorphous silicon and the large device-to-device variations found in polycrystalline silicon, other materials have been studied for use in TFTs. These include cadmium selenide, metal oxides such as indium gallium zinc oxide (IGZO) or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrari
Ferrari S.p.A. (; ) is an Italian luxury sports car manufacturer based in Maranello. Founded in 1939 by Enzo Ferrari (1898–1988), the company built Auto Avio Costruzioni 815, its first car in 1940, adopted its current name in 1945, and began to produce its current line of road cars in 1947. Ferrari became a public company in 1960, and from 1963 to 2014 it was a subsidiary of Fiat S.p.A. It was Corporate spin-off, spun off from Fiat's successor entity, Fiat Chrysler Automobiles, in 2016. The company currently offers a large model range which includes several supercars, grand tourers, and one SUV. Many early Ferraris, dating to the 1950s and 1960s, count among the List of most expensive cars sold at auction, most expensive cars ever sold at auction. Throughout History of Ferrari, its history, the company has been noted for its continued participation in Auto racing, racing, especially in Formula One, where its team, Scuderia Ferrari, is the series' single oldest and most su ...

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. Many carriers (such as AT&T, U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alltel
Alltel was a landline, wireless service provider, wireless and general Telephone company, telecommunications services provider, primarily based in the United States.
