Palm Centro
The Palm Centro is a smartphone marketed by Palm, Inc. beginning its release on October 14, 2007 offering the functionality of the larger Treo 755p in a smaller size. The Centro is one of the last devices to run the Palm OS operating system. The successor to Palm OS is webOS, which debuted on the Palm Pre in June 2009. Currently, the Centro still works with some carriers, but not with others. 2G GSM devices, such as the AT&T Centro, can no longer connect to the AT&T network. Once Verizon's 3G network is shut down, Verizon Centro devices will only work offline. Specifications With a weight of 119 g, and dimensions of 4.2″ (h), 2.1″ (w) and 0.7″ (d), the Centro was the smallest-ever Palm smartphone at the time of its introduction. It includes a 1.3-megapixel digital camera with video capture capabilities, microSD card slot (officially supporting up to 8 GB microSD cards, though in practice, microSD cards up to 64 GB work), touch screen navigation and a QWERTY keyboard.

Touchscreen
A touchscreen or touch screen is the assembly of both an input ('touch panel') and output ('display') device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size. The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or other such devices (other than a stylus, which is opt ...

Palm Pre
The Palm Pre , styled as palm prē, is a multitasking smartphone that was designed and marketed by Palm with a multi-touch screen and a sliding keyboard. The smartphone was the first to use Palm's Linux-based mobile operating system, webOS. The Pre functions as a camera phone and a portable media player, and has location and navigation capabilities.

A revised model, the Palm Pre Plus, which doubled the available memory and internal storage, was launched on January 25, 2010, for Verizon Wireless and later released on AT&T Mobility on May 16, 2010. The third generation of Palm P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Claus
Santa Claus, also known as Father Christmas, Saint Nicholas, Saint Nick, Kris Kringle, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring children gifts during the late evening and overnight hours on Christmas Eve of toys and candy or coal or nothing, depending on whether they are "naughty or nice". In the legend, he accomplishes this with the aid of Christmas elves, who make the toys in his workshop, often said to be at the North Pole, and flying reindeer who pull his sleigh through the air. The modern figure of Santa is based on folklore traditions surrounding Saint Nicholas, the English figure of Father Christmas and the Dutch figure of '' Sinterklaas''. Santa is generally depicted as a portly, jolly, white- bearded man, often with spectacles, wearing a red coat with white fur collar and cuffs, white-fur-cuffed red trousers, red hat with white fur, and black leather belt and boots, carrying a bag full of gifts for ...

Telecommunications Network
A telecommunications network is a group of nodes interconnected by telecommunications links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals. Multiple nodes may cooperate to pass the message from an originating node to the destination node, via multiple network hops. For this routing function, each node in the network is assigned a network address for identification and locating it on the network. The collection of addresses in the network is called the address space of the network. Examples of telecommunications networks include computer networks, the Internet, the public switched telephone network (PSTN), the global Telex network, the aeronautical ACARS network, and the wireless radio networks of cell phone telecommunication providers. Network structure In general, every telecommunications network conceptu ... [...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] |

Backward Compatibility
Backward compatibility (sometimes known as backwards compatibility) is a property of an operating system, product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system, especially in telecommunications and computing. Modifying a system in a way that does not allow backward compatibility is sometimes called " breaking" backward compatibility. A complementary concept is forward compatibility. A design that is forward-compatible usually has a roadmap for compatibility with future standards and products. A related term from programming jargon is hysterical reasons or hysterical raisins (near-homophones for "historical reasons"), as the purpose of some software features may be solely to support older hardware or software versions. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM radio in stereo. FM radio was initially mono, with only one audio channel repre ...

Stock-keeping Unit
In inventory management, a stock keeping unit (abbreviated as SKU and pronounced or ) is the unit of measure in which the stocks of a material are managed. Or to put it another way; is a distinct type of item for sale, purchased, or tracked in inventory, such as a product or service, and all attributes associated with the item type that distinguish it from other item types. (For a product, these attributes can include manufacturer, description, material, size, color, packaging, and warranty terms.) When a business records the inventory of its stock, it counts the quantity it has of each unit, or SKU. SKU can also refer to a unique identifier or code, sometimes represented via a barcode for scanning and tracking, that refers to the particular stock keeping unit. These identifiers are not regulated or standardized. When a company receives items from a vendor, it has a choice of maintaining the vendor's SKU or creating its own. This makes them distinct from Global Trade Item Number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
