Treo 680
The Palm Treo 680 is a combination hybrid PDA/cellphone, or smartphone as the successor to the company's Treo 650. It was the first-ever Palm OS Treo with no external antenna. The Treo 680 is older, larger, and heavier than the Palm Centro. But the Treo 680 has a larger keyboard which is more comfortable to type on. There are other differences between the Treo 680 and the Centro. An article on the Treonauts weblog includes a good comparison chart and some in-depth commentary.

Palm, Inc
Palm, Inc. was an American company that specialized in manufacturing personal digital assistants (PDAs) and various other electronics. They were the designer of the PalmPilot, the first PDA successfully marketed worldwide, as well as the Treo 600, one of the first smartphones. Palm developed several versions of Palm OS for PDAs and smartphones. The company was also responsible for the first versions of webOS, the first multitasking operating system for smartphones, and enyo (software), enyo.js, a framework for HTML5 apps. In July 2010, Palm was purchased by Hewlett-Packard (HP) and in 2011 announced a new range of webOS products. However, after poor sales, HP CEO Léo Apotheker announced in August 2011 that it would end production and support of Palm and webOS devices, marking the end of the Palm brand after 19 years. In October 2014, HP sold the Palm trademark to a shelf corporation tied to the Chinese electronics firm TCL Corporation. Shortly afterward, TCL confirmed its plans ...

Infrared Data Association
The Infrared Data Association (IrDA) is an industry-driven interest group that was founded in 1994 by around 50 companies. IrDA provides specifications for a complete set of protocols for wireless infrared communications, and the name "IrDA" also refers to that set of protocols. The main reason for using the IrDA protocols had been wireless data transfer over the "last one meter" using point-and-shoot principles. Thus, it has been implemented in portable devices such as mobile telephones, laptops, cameras, printers, and medical devices. The main characteristics of this kind of wireless optical communication are physically secure data transfer, line-of-sight (LOS) and very low bit error rate (BER) that makes it very efficient. Specifications IrPHY The mandatory IrPHY (Infrared Physical Layer Specification) is the physical layer of the IrDA specifications. It comprises optical link definitions, modulation, coding, cyclic redundancy check (CRC) and the framer. Different data r ...

StrataFlash
StrataFlash is a NOR flash memory technology first developed by Intel. It stores two or more bits of information per cell rather than just one, in an architecture called multi-level cell In electronics, a multi-level cell (MLC) is a memory cell capable of storing more than a single bit of information, compared to a single-level cell (SLC), which can store only one bit per memory cell. A memory cell typically consists of a single ... (MLC). This is accomplished by storing intermediate voltage levels instead of using only the two levels (discharged = "0" and charged = "1") of traditional binary memories. The StrataFlash technology evolved out of Intel's ETOX flash memory products. Two bits per cell are achieved with four levels of voltage, while three bits per cell can be achieved with eight levels. Research of this technology began in 1992 and the first commercial products were released in 1997. Further developments allowed faster read speeds by offering synchronous burst mode ...

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers and other co ...

Smartphone
A smartphone is a portable computer device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile Phone
A mobile phone, cellular phone, cell phone, cellphone, handphone, hand phone or pocket phone, sometimes shortened to simply mobile, cell, or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called ''cellular telephones'' or ''cell phones'' in North America. In addition to telephony, digital mobile phones ( 2G) support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games and digital photography. Mobile phones offering only those capabilities are known as fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Digital Assistant
A personal digital assistant (PDA), also known as a handheld PC, is a variety mobile device which functions as a personal information manager. PDAs have been mostly displaced by the widespread adoption of highly capable smartphones, in particular those based on iOS and Android. A PDA has an electronic visual display. Most models also have audio capabilities, allowing usage as a portable media player, and also enabling many of them to be used as telephones. Nearly all modern PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless WANs, letting them include a web browser. Sometimes, instead of buttons, PDAs employ touchscreen technology. The first PDA, the Organiser, was released in 1984 by Psion, followed by Psion's Series 3, in 1991. The latter began to resemble the more familiar PDA style, including a full keyboard. The term ''PDA'' was first used on January 7, 1992 by Apple Inc. CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
