Form Factor (mobile Phones)
The form factor of a mobile phone is its size, shape, and style, as well as the layout and position of its major components. With one non-movable section Bar A bar (also known as a slab, block, candybar) phone takes the shape of a cuboid, usually with rounded corners and/or edges. The name is derived from the rough resemblance to a chocolate bar in size and shape. This form factor is widely used by a variety of manufacturers, such as Nokia and Sony Ericsson. Bar-type smartphones commonly have the screen and keypad on a single face. Sony had a well-known 'Mars Bar' phone model CM-H333 in 1993. Bar phones without a full keyboard tend to have a 3×4 numerical keypad; text is often generated on such systems using the Text on 9 keys algorithm. Keyboard bars These are variants of bars that have a full QWERTY keyboard on the front. While they are technically the same as a regular bar phone, the keyboard and all the buttons make them look significantly different. Devices like these we ...

Cuboid
In geometry, a cuboid is a hexahedron, a six-faced solid. Its faces are quadrilaterals. Cuboid means "like a cube", in the sense that by adjusting the length of the edges or the angles between edges and faces a cuboid can be transformed into a cube. In mathematical language a cuboid is a convex polyhedron, whose polyhedral graph is the same as that of a cube. Special cases are a cube, with 6 squares as faces, a rectangular prism, rectangular cuboid or rectangular box, with 6 rectangles as faces, for both, cube and rectangular prism, adjacent faces meet in a right angle. General cuboids By Euler's formula the numbers of faces ''F'', of vertices ''V'', and of edges ''E'' of any convex polyhedron are related by the formula ''F'' + ''V'' = ''E'' + 2. In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges. Along with the rectangular cuboids, any parallel ...

BlackBerry Q10
The BlackBerry Q10 is a touchscreen-based QWERTY smartphone developed by BlackBerry, previously known as RIM (Research In Motion). The BlackBerry Q10 is the second of two BlackBerry smartphones unveiled at the BlackBerry 10 event on January 30, 2013. Hardware The device has the company's distinctive QWERTY keyboard similar to that found on the BlackBerry Bold series and a 3.1-inch square Super-AMOLED capacitive multi-touch display (built on 77 µm pixel size). The screen displays at 720x720 px resolution at 328 ppi. This is the first device based on new BlackBerry 10 OS to have physical keyboard; another first is a HDMI port to connect a TV or monitor to the cellphone.

Paperweight
A paperweight is a small solid object heavy enough, when placed on top of papers, to keep them from blowing away in a breeze or from moving under the strokes of a painting brush (as with Chinese calligraphy). While any object, such as a stone, can serve as a paperweight, decorative paperweights of glass are produced, either by individual artisans or factories, usually in limited editions, and are collected as works of fine glass art, some of which are exhibited in museums. First produced in about 1845, particularly in France, such decorative paperweights declined in popularity before undergoing a revival in the mid-twentieth century. Basic features Decorative glass paperweights have a flat or slightly concave base, usually polished but sometimes frosted, cut in one of several variations (e.g. star-cut bases have a multi-pointed star, while a diamond cut base has grooves cut in a criss-cross pattern), although a footed weight has a flange in the base.

AC Adapter
An AC adapter or AC/DC adapter is a type of external power supply, often enclosed in a case similar to an AC plug. Other common names include wall wart, power brick, wall charger, and power adapter. Adapters for battery-powered equipment may be described as chargers or rechargers (see also battery charger). AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power. The internal circuitry of an external power supply is very similar to the design that would be used for a built-in or internal supply. External power supplies are used both with equipment with no other source of power and with battery-powered equipment, where the supply, when plugged in, can sometimes charge the battery in addition to powering the equipment. Use of an external power supply allows portability of equipment powered either by mains or battery without the added bulk of internal power components, ...

Brick
A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term ''brick'' denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks. Bricks can be joined using mortar, adhesives or by interlocking them. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. ''Block'' is a similar term referring to a rectangular building unit composed of similar materials, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate. Fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since circa 4000 BC. Air-dried bricks, also known as mud-bricks, have a history older than fired bricks, and have an addit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Hardware
Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware. Hardware is so-termed because it is " hard" or rigid with respect to changes, whereas software is "soft" because it is easy to change. Hardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware. Von Neumann architecture The template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic log ...

Firmware
In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems (running embedded software), home and personal-use appliances, computers, and computer peripherals. Firmware is held in non-volatile memory devices such as ROM, EPROM, EEPROM, and flash memory. Updating firmware requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Some firmware memory devices are permanently installed and cannot be changed after manufactu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Router (computing)
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions between networks and on the global Internet. Data sent through a network, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node. A router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. The most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. More sophisticated routers, ...

Game Console
A video game console is an electronic device that outputs a video signal or image to display a video game that can be played with a game controller. These may be home consoles, which are generally placed in a permanent location connected to a television or other display devices and controlled with a separate game controller, or handheld consoles, which include their own display unit and controller functions built into the unit and which can be played anywhere. Hybrid consoles combine elements of both home and handheld consoles. Video game consoles are a specialized form of a home computer geared towards video game playing, designed with affordability and accessibility to the general public in mind, but lacking in raw computing power and customization. Simplicity is achieved in part through the use of game cartridges or other simplified methods of distribution, easing the effort of launching a game. However, this leads to ubiquitous proprietary formats that creates competit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consumer Electronics
Consumer electronics or home electronics are electronic ( analog or digital) equipment intended for everyday use, typically in private homes. Consumer electronics include devices used for entertainment, communications and recreation. Usually referred to as black goods due to many products being housed in black or dark casings. This term is used to distinguish them from " white goods" which are meant for housekeeping tasks, such as washing machines and refrigerators, although nowadays, these would be considered black goods, some of these being connected to the Internet. In British English, they are often called brown goods by producers and sellers. In the 2010s, this distinction is absent in large big box consumer electronics stores, which sell entertainment, communication and home office devices, light fixtures and appliances, including the bathroom type. Radio broadcasting in the early 20th century brought the first major consumer product, the broadcast receiver. Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brick (electronics)
A brick (or bricked device) is a mobile device, game console, router or other consumer electronic device that is no longer functional due to corrupted firmware, a hardware problem, or other damage. The term analogizes the device to a brick's modern technological usefulness. Cause and prevention Bricking a device is most often a result of interrupting an attempt to update the device. Many devices have an update procedure which must not be interrupted before completion; if interrupted by a power failure, user intervention, or any other reason, the existing firmware may be partially overwritten and unusable. The risk of corruption can be minimized by taking all possible precautions against interruption. Installing firmware with errors, or for a different revision of the hardware, or installing firmware incompetently patched such as DVD firmware which only plays DVDs sold in a particular region, can also cause bricking. Devices can also be bricked by malware ( malicious sof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
H2g2
The h2g2 website is a British-based collaborative online encyclopedia project. It describes itself as "an unconventional guide to life, the universe, and everything", in the spirit of the fictional publication '' The Hitchhiker's Guide to the Galaxy'' from the science fiction comedy series of the same name by Douglas Adams. It was founded by Adams in 1999 and was run by the BBC between 2001 and 2011. The intent is to create an Earth-focused guide that allows members to share information about their geographic area and the local sites, activities and businesses, to help people decide where they want to go and what they may find when they get there. It has grown to contain subjects from restaurants and recipes, to quantum theory and history. Explicit advertising of businesses was forbidden when the site was run by the BBC, but customer reviews were permitted. – ''No Spitting.
