BlackBerry Evolve
The following is a partial list of BlackBerry products. BlackBerry is a line of wireless Mobile device, handheld devices first introduced in 1996 and manufactured by the Canadian company BlackBerry (company), BlackBerry, formerly known as Research In Motion (RIM). Early pager models These two-way pager models had thumb keyboards, with a thumbwheel for scrolling its monochrome text display. The first model, the Inter@ctive Pager, was announced on September 18, 1996. Within a year, Yankee Group was estimating that devices like the Inter@ctive Pager were in use by fewer than 400,000 people and expected two-way wireless messaging services to attract 51 million users by 2002. They provided e-mail and Wireless Application Protocol, WAP services, with limited HTML access provided via third party software such as PocketGenie, WolfeTech PocketGenie or GoAmerica browser. They were built for use with two 1G data-only packet switched networks: Mobitex and DataTAC. They did not support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BlackBerry
BlackBerry is a discontinued brand of handheld devices and related mobile services, originally developed and maintained by the Canadian company Research In Motion (RIM, later known as BlackBerry Limited) until 2016. The first BlackBerry device launched in 1999 in North America, running on the Mobitex network (later also DataTAC) and became very popular because of its "always on" state and ability to send and receive email messages wirelessly. The BlackBerry pioneered push notifications and popularized the practise of " thumb typing" using its QWERTY keyboard, something that would become a trademark feature of the line. In its early years, the BlackBerry proved to be a major advantage over the (typically) one-way communication pagers and it also removed the need for users to tether to personal computers. It became especially used in the corporate world in the US and Canada. RIM debuted the BlackBerry in Europe in September 2001, but it had less appeal there where text mess ...

Java Virtual Machine
A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation. Having a specification ensures interoperability of Java programs across different implementations so that program authors using the Java Development Kit (JDK) need not worry about idiosyncrasies of the underlying hardware platform. The JVM reference implementation is developed by the OpenJDK project as open source code and includes a JIT compiler called HotSpot. The commercially supported Java releases available from Oracle are based on the OpenJDK runtime. Eclipse OpenJ9 is another open source JVM for OpenJDK. JVM specification The Java virtual machine is an abstract (virtual) computer defined by a specification. It is a part of the Java runtime environment. The garbage collection ...

GPRS
General Packet Radio Service (GPRS), also called 2.5G, is a mobile data standard on the 2G cellular communication network's Global System for Mobile Communications, global system for mobile communications (GSM). Networks and mobile devices with GPRS started to roll out around the year 2001; it offered, for the first time on GSM networks, seamless data transmission using Packet switching, packet data for an "always-on" connection (eliminating the need to "dial-up"), so providing improved Internet access for World Wide Web, web, email, Wireless Application Protocol, WAP services, Multimedia Messaging Service (MMS) and others. Up until the rollout of GPRS, only circuit switched data was used in cellular networks, meaning that one or more radio channels were occupied for the entire duration of a data connection. On the other hand, on GPRS networks, data is broken into small packets and transmitted through available channels. This increased efficiency also gives it theoretical data ...

Global System For Mobile Communications
The Global System for Mobile Communications (GSM) is a family of standards to describe the protocols for second-generation ( 2G) digital cellular networks, as used by mobile devices such as mobile phones and mobile broadband modems. GSM is also a trade mark owned by the GSM Association. "GSM" may also refer to the voice codec initially used in GSM. 2G networks developed as a replacement for first generation ( 1G) analog cellular networks. The original GSM standard, which was developed by the European Telecommunications Standards Institute (ETSI), originally described a digital, circuit-switched network optimized for full duplex voice telephony, employing time division multiple access (TDMA) between stations. This expanded over time to include data communications, first by circuit-switched transport, then by packet data transport via its upgraded standards, GPRS and then EDGE. GSM exists in various versions based on the frequency bands used. GSM was first implemented in Fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Niche Market
A niche market is the subset of the market on which a product is appealed to a small group of consumers. The market niche defines the product features aimed at satisfying specific market needs, as well as the price range, production quality and the demographics that it is intended to target. It is also a small market segment. Sometimes, a product or service can be entirely designed to satisfy a niche market. Not every product can be defined by its market niche. The niche market is highly specialized, and aiming to survive among the competition from numerous super companies. Even established companies create products for different niches; Hewlett-Packard has all-in-one machines for printing, scanning and faxing targeted for the home office niche, while at the same time having separate machines with one of these functions for big businesses. In practice, product vendors and trade businesses are commonly referred to as ''mainstream providers'' or ''narrow demographics niche market pr ...

Mobile Phone
A mobile phone or cell phone is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones ( landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America. Beyond traditional voice communication, digital mobile phones have evolved to support a wide range of additional services. These include text messaging, multimedia messaging, email, and internet access (via LTE, 5G NR or Wi-Fi), as well as short-range wireless technologies like Bluetooth, infrared, and ultra-wideband (UWB). Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flash Memory
Flash memory is an Integrated circuit, electronic Non-volatile memory, non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR gate, NOR and NAND gate, NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level, depending on whether the state of the bit line or word lines is pulled high or low; in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented by Fujio Masuoka at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than the entire devi ...
