Palm Zire 71
The Zire Series was Palm, Inc's "consumer-grade" brand of Personal Digital Assistant. Background/Overview The lower-end models emphasized value â Palm's original Zire model was the first PDA under $100 from a major manufacturer â and the higher-end models emphasized multimedia capability, including features like cameras and audio playback functions suitable for listening to MP3s. Models Palm Zire & Palm Zire 21 The Palm Zire and Palm Zire 21 were inexpensive and are differentiated from the rest of Palm's line by having monochrome screens without backlighting, having only two application buttons instead of the typical four, and traditional up/down scroll buttons instead of the then-standard 5-way navigator found in other models. Both of these entry-level models are lightweight (3.8oz or 108g) and sport a white plastic face with a matte gray plastic back. The Zire (also known as the m150), released in the fourth quarter of 2002 and is the handheld responsible for starting the ...

PalmOne
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 LÊo 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 ...

Gigabyte
The gigabyte () is a multiple of the unit byte for digital information. The prefix ''giga'' means 109 in the International System of Units (SI). Therefore, one gigabyte is one billion bytes. The unit symbol for the gigabyte is GB. This definition is used in all contexts of science (especially data science), engineering, business, and many areas of computing, including storage capacities of hard drives, solid state drives, and tapes, as well as data transmission speeds. However, the term is also used in some fields of computer science and information technology to denote (10243 or 230) bytes, particularly for sizes of RAM. Thus, prior to 1998, some usage of ''gigabyte'' has been ambiguous. To resolve this difficulty, IEC 80000-13 clarifies that a ''gigabyte'' (GB) is 109 bytes and specifies the term ''gibibyte'' (GiB) to denote 230 bytes. These differences are still readily seen for example, when a 400 GB drive's capacity is displayed by Microsoft Windows as 372 G ...

SanDisk
SanDisk is a brand for flash memory products, including memory cards and readers, USB flash drives, solid-state drives, and digital audio players, manufactured and marketed by Western Digital. The original company, SanDisk Corporation was acquired by Western Digital in 2016. Western Digital was the fourth-largest manufacturer of flash memory having declined from third-largest in 2014. History SanDisk was founded in 1988 by Eli Harari, Sanjay Mehrotra, and Jack Yuan, incorporated at the time as SunDisk. SanDisk co-founder Eli Harari developed the Floating Gate EEPROM which proved the practicality, reliability and endurance of semiconductor-based data storage. In 1991 SanDisk produced the first flash-based solid-state drive (SSD) in a 2.5-inch hard disk drive form factor for IBM with a 20 MB capacity priced at about $1,000. In 1992, SanDisk (then SunDisk) introduced FlashDisk, a series of memory cards made for the PCMCIA or PC card form factor, so they could be inserted int ...

Wi-Fi
Wi-Fi () is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks in the world, used globally in home and small office networks to link desktop and laptop computers, tablet computers, smartphones, smart TVs, printers, and smart speakers together and to a wireless router to connect them to the Internet, and in wireless access points in public places like coffee shops, hotels, libraries and airports to provide visitors with Internet access for their mobile devices. ''Wi-Fi'' is a trademark of the non-profit Wi-Fi Alliance, which restricts the use of the term ''Wi-Fi Certified'' to products that successfully complete interoperability certification testing. the Wi-Fi Alliance consisted of more than 800 companies from around the world. over 3.05 billion ...

Zire 72
The Zire 72 is Palm, Inc.'s second Personal Digital Assistant with an integrated digital camera. Introduced in 2004, it is the replacement for the Zire 71, having a 1.2 megapixel camera, 32 MB of memory, built-in Bluetooth wireless communication, video recording and playback capability, a built-in microphone, hi-res hi-color screen, SecureDigital smartcard slot, and a 312 MHz Intel PXA270 processor. Users have complained about several problems, most notably *Blue paint peels off (a "special edition" version has been released that has no blue paint, just silver.) *Camera quality (broken pixels, uncovered lens etc.) *Screen whining *Battery life Palm, Inc. released a second version of the Zire 72, the Zire 72s, which is silver. This change fixed the problem with the paint. They subsequently released a version of the blue Zire 72, which used a different paint, and does not peel. As with other Bluetooth enabled devices, turning that connectivity off when not required, exten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SD Card
Secure Digital, officially abbreviated as SD, is a proprietary non-volatile flash memory card format developed by the SD Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCards (MMCs), and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. History 1999â2003: Creation In 1999, SanDisk, Panasonic (Matsushita), and Toshiba agreed to develop and market the S ... [...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] |

Non-Volatile File System
Non-Volatile File System (NVFS) is a flash memory file system introduced in the release of Palm's Personal Digital Assistant handheld models Tungsten T5, Tungsten E2, Palm TX, Z22, Treo 650/700/ 680/ 755p, and Palm Centro. Background Overview of NVFS The NVFS, as claimed by palmOne, is a file system designed to keep all information safe should the battery run out of power. Previous non-flash memory designs would lose all stored data in the event of a power loss. ''NVFS'' is a derivative of Flash Memory, which continually stores all data even when no power is applied. palmOne invented NVFS in response to complaints that a handheld's data was destroyed when the battery power ran out. In the past, it was necessary to keep the handheld continuously charged to avoid losing data, since all information was stored in volatile memory. A similar feature has been adopted by PDAs running the Windows Mobile 5.0 operating system, and is named "Persistent Storage". Architecture and specific ...

NVRAM
Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data indefinitely without electric power. Read-only memory devices can be used to store system firmware in embedded systems such as an automotive ignition system control or home appliance. They are also used to hold the initial processor instructions required to bootstrap a computer system. Read-write memory can be used to store calibration constants, passwords, or setup information, and may be integrated into a microcontroller. If the main memory of a computer system were non-volatile, it would greatly reduce the time required to start a system after a power interruption. Current existing types of semi ...
