Nokia Lumia 2520
The Nokia Lumia 2520 is a Windows RT tablet computer originally developed by Nokia. It is Nokia's first and only Windows-based tablet, and the company's first tablet since its Nokia Internet Tablet line. Sharing its design and marketed with the Nokia Lumia series of Windows Phone products, the device incorporates a quad-core Snapdragon 800 chip with 4G LTE support, along with a 10.1-inch (26 cm) 1080p display and an optional "Power Keyboard" dock adding additional battery capacity, USB ports, and a physical hardware keyboard. Following a period of speculation and leaks, the Lumia 2520 was officially unveiled on 22 October 2013, and released in North America on 21 November 2013. The 2520 was met with mostly positive reviews, praising its design, display, and for being the first Windows RT tablet to offer cellular data (although Microsoft's own Surface 2 was soon available with such an option). However, the device also received criticism for the lack of available so ...

Bluetooth V4
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet Blue ...

1080p
1080p (1920×1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the ''p'' stands for progressive scan, ''i.e.'' non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes informally referred to as 2K, these terms reflect two distinct technical standards, with differences including resolution and aspect ratio. 1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movies, consumer-grade televisions and projector ...

LTE (telecommunication)
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is also called 3.95G and has been marketed as "4G LTE" and "Advanced 4G"; but it does not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. The requirements were set forth by the ITU-R organisation ...

Windows Phone
Windows Phone (WP) is a discontinued family of mobile operating systems developed by Microsoft for smartphones as the replacement successor to Windows Mobile and Zune. Windows Phone featured a new user interface derived from the Metro design language. Unlike Windows Mobile, it was primarily aimed at the consumer market rather than the enterprise market. It was first launched in October 2010 with Windows Phone 7. Windows Phone 8 succeeded it in 2012, replacing the Windows CE-based kernel of Windows Phone 7 with the Windows NT kernel used by the PC versions of Windows (and, in particular, a large amount of internal components from Windows 8). Due to these changes, the OS was incompatible with all existing Windows Phone 7 devices, although it still supported apps originally developed for Windows Phone 7. In 2014, Microsoft released the Windows Phone 8.1 update, which introduced the Cortana virtual assistant, and Windows Runtime platform support to create cross-platform apps betwee ...

Nokia Lumia
Microsoft Lumia (previously the Nokia Lumia) is a discontinued line of mobile devices that was originally designed and marketed by Nokia and later by Microsoft Mobile. Introduced in November 2011, the line was the result of a long-term partnership between Nokia and Microsoft—as such, Lumia smartphones run on Microsoft software, the Windows Phone operating system; and later the newer Windows 10 Mobile. The Lumia name is derived from the partitive plural form of the Finnish word ''lumi'', meaning "snow". On 3 September 2013, Microsoft announced its purchase of Nokia's mobile device business, with the deal closing on 25 April 2014. As a result, the Lumia line's maintenance was transferred to Microsoft Mobile. As part of the transition, Microsoft continued to use the Nokia brand on Lumia devices until October 2014, when it began to officially phase out the Nokia name in its promotion and production of smartphones in favor of Microsoft branding. In November 2014, Microsoft announced ...

Microsoft Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, do what other personal computers do, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops which have traditionally run off operating systems usually designed for desktops, tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classifie ...

Microsoft Surface 3
Surface 3 is a 2-in-1 detachable from the Microsoft Surface series, introduced by Microsoft in 2015. Unlike its predecessor, the Surface 2, Surface 3 utilizes an x86 Intel Atom system-on-chip architecture, or SoC, rather than a processor with ARM architecture such as the Nvidia Tegra that powered the Surface 2, and runs standard versions of Windows 8.1 or Windows 10. History The older, original Surface (also known as Surface RT) and Surface 2, with their ARM-based processors and Windows RT operating system, were designed to compete with the iPad and other tablets. The first Surface was criticized for performance issues, which were reduced in the succeeding Surface 2. Due to the differing processors, these devices were incompatible with the vast number of Windows programs written for x86-based computers, running only those written and compiled for Windows RT, loaded from Microsoft's application store. Released prior to Surface 3, the Surface Pro 3 – featuring ...

IEEE 802
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LAN), personal area network (PAN), and metropolitan area networks (MAN). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active. The IEEE 802 standards are restricted to computer networks carrying variable-size packets, unlike cell relay networks, for example, in which data is transmitted in short, uniformly sized units called cells. Isochronous signal networks, in which data is transmitted as a steady stream of octets, or groups of octets, at regular time intervals, are also outside the scope of the IEEE 802 standards. The number 802 has no significance: it was simply the next number in the sequence that the IEEE used for standards projects. ...
