Open Programming Language
Open Programming Language (OPL) is a programming language for embedded systems and mobile devices that run the operating systems EPOC and Symbian. It was released by the British company Psion in 1984. Use Originally designed for use on their classic Psion PDAs such as the Series 3, 5/5mx, Series 7, and netBook–netPad, and the Psion produced MC218, OPL was provided as part of the standard application suite. It can also be installed on the Nokia 9200, 9300 and 9500 Communicator series mobile telephone and personal digital assistant (PDA) and the Sony Ericsson P800, P900, P910 series. OPL is also included in Psion Teklogix industrial handhelds such as the Workabout mx, and it also appeared in the lesser known Oregon 'Osaris' organiser, a broadly compatible EPOC32 device that uniquely used version 4 of the OS. OPL is an interpreted language similar to BASIC. A fully Visual Basic-compatible language OVAL has been also developed. History The language was originally named ' ...

Imperative Programming
In computer science, imperative programming is a programming paradigm of software that uses statements that change a program's state. In much the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform. Imperative programming focuses on describing ''how'' a program operates step by step, rather than on high-level descriptions of its expected results. The term is often used in contrast to declarative programming, which focuses on ''what'' the program should accomplish without specifying all the details of ''how'' the program should achieve the result. Imperative and procedural programming Procedural programming is a type of imperative programming in which the program is built from one or more procedures (also termed subroutines or functions). The terms are often used as synonyms, but the use of procedures has a dramatic effect on how imperative programs appear and how they are constructed ...

Psion Series 5
The Psion Series 5 was a personal digital assistant (PDA) from Psion. It came in two main variants, the ''Series 5'' (launched in 1997) and the ''Series 5mx'' (1999), the latter having a faster processor, clearer liquid crystal display (LCD), and updated software. There was also a rare ''Series 5mx Pro'', which differed only in having the operating system (OS) loaded into random-access memory (RAM) and hence upgradeable. Ericsson marketed a version of the Series 5mx renamed as ''MC218''. The Psion Series 5 was a major upgrade from the Psion Series 3. A Psion Series 4 does not exist, due to Psion's concern of tetraphobia in their Asian markets. The external appearance of the Psion Series 5 and the Psion Series 5mx are broadly similar, but their mainboards and other internal components were different and not interchangeable. The screens are not interchangeable because of different screen cables. The Series 5 was the first to feature a unique sliding clamshell design, whereby the ...

Interpreted Language
In computer science, an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program. An interpreter generally uses one of the following strategies for program execution: # Parse the source code and perform its behavior directly; # Translate source code into some efficient intermediate representation or object code and immediately execute that; # Explicitly execute stored precompiled bytecode made by a compiler and matched with the interpreter Virtual Machine. Early versions of Lisp programming language and minicomputer and microcomputer BASIC dialects would be examples of the first type. Perl, Raku, Python, MATLAB, and Ruby are examples of the second, while UCSD Pascal is an example of the third type. Source programs are compiled ahead of time and stored as machine independent code, which is then linked at run-time and executed by ...

Sony Ericsson P910
The Sony Ericsson P910 is a smartphone by Sony Ericsson introduced in 2004 and the successor of the Sony Ericsson P900. The P910 has a full QWERTY keyboard on the back of the flip (the flip can also be removed completely, allowing for a 'traditional' PDA form-factor). The biggest change from the P900 to the P910 is that the P910 supports Memory Stick PRO Duo and the phone's internal memory has been upped from 16 MB to 64 MB. Although Memory Stick PRO Duo comes in larger capacities, the maximum supported by the P910i is 2 GB. It is powered by an ARM9 processor clocked at 156 MHz and runs the Symbian OS with the UIQ graphical user interface. Also, the touchscreen displays 262,144 colours (an 18-bit colour depth), as opposed to the P900's 65,536 (16-bit). It comes in three versions: * P910i (GSM 900/1800/1900) * P910c (GSM 900/1800/1900 for China mainland) * P910a (GSM 850/1800/1900 for North America and Latin America) One of the key aspects of the P910 is its ab ...

Sony Ericsson P900
The Sony Ericsson P900 is a Symbian OS v7.0 based smartphone from Sony Ericsson. It was introduced in 2003 and is the successor of the Sony Ericsson P800; like the P800, the P900 uses the UIQ platform. Like other Symbian-based smartphones of its time, but unlike Ericsson R380, the P900 is an open phone. This means that it is possible to develop and install third party applications without restrictions. A UIQ 2.1 SDK based upon Symbian C++ is freely available from the Sony Ericsson developer website. Additionally, the P900 supports applications written in Java. Because of this openness, many third-party applications exist that can be used on the P900 and other UIQ phones (such as the Motorola A1000 and BenQ P30). Many are shareware and freeware. As the P900 uses UIQ version 2.1, it is backwards compatible with UIQ 2.0 as found in the P800. Applications made for the P800 will normally work on a P900 as well. It, like the P800 and P910i, has an ARM9 processor clocked at 156 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sony Ericsson P800
The Sony Ericsson P800 is a smartphone introduced in 2002 based upon UIQ version 2.0 (which itself is based upon Symbian OS v7.0) from Sony Ericsson. The P800 is considered the successor of the Ericsson R380, and initial design work was done within Ericsson, but it was produced after Sony & Ericsson merged their mobile phone businesses. The P800 uses the UIQ (version 2.0) user interface and has a touch screen much like a PDA. It is powered by an ARM9 processor running at 156MHz, which was also used for the successive models Sony Ericsson P900, Sony Ericsson P910. It came with a 16MB Memory Stick Duo but supports up to 128MB. The touchscreen displays 4,096 colours (12-bit colour depth). It was succeeded in 2003 by the Sony Ericsson P900. A long awaited updated version of the "P" series phones, the Sony Ericsson P990 was launched at the Symbian Smartphone Show in September 2005. It is based upon the UIQ3 platform (utilizing Symbian OS v9.1). The latest successor is the Sony Ericsso ... [...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] |
Mobile Telephone
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 featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
