Phablet
A phablet (, ) is a mobile device combining or straddling the size formats of smartphones and tablets. The word is a blend word of ''phone'' and ''tablet''. The term was largely unused by the late 2010s, since average phone sizes eventually morphed into small tablet sizes, up to , with wider aspect ratios. Appearance Phablets feature large displays that complement screen-intensive activity such as web browsing, video gaming, and multimedia viewing. They may also include software optimized for an integral self-storing stylus to facilitate sketching, note-taking, drawing and annotation. Phablets were originally designed for the Asian market where consumers could not afford both a smartphone and tablet as in North America; phones for that market are known for having "budget-specs-big-battery" with large low resolution screens and midrange processors, although other phablets have flagship specifications. Since then, phablets in North America have also become successful for several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Home Automation
Home automation or domotics is building automation for a home. A home automation system will monitor and/or control home attributes such as lighting, climate, entertainment systems, and appliances. It may also include home security such as access control and alarm systems. The phrase smart home refers to home automation devices that have internet access. Home automation, a broader category, includes ''any'' device that can be monitored or controlled via wireless radio signals, not just those having internet access. When connected with the Internet, home sensors and activation devices are an important constituent of the Internet of Things ("IoT"). A home automation system typically connects controlled devices to a central smart home hub (sometimes called a " gateway"). The user interface for control of the system uses either wall-mounted terminals, tablet or desktop computers, a mobile phone application, or a Web interface that may also be accessible off-site through ...

Distributed Computing
Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. The components of a distributed system communicate and coordinate their actions by passing messages to one another in order to achieve a common goal. Three significant challenges of distributed systems are: maintaining concurrency of components, overcoming the lack of a global clock, and managing the independent failure of components. When a component of one system fails, the entire system does not fail. Examples of distributed systems vary from SOA-based systems to microservices to massively multiplayer online games to peer-to-peer applications. Distributed systems cost significantly more than monolithic architectures, primarily due to increased needs for additional hardware, servers, gateways, firewalls, new subnets, proxies, and so on. Also, distributed systems are prone to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Form Factor (design)
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard. It may also define an entire system, as in a computer form factor. Evolution and standardization As electronic hardware has become smaller following Moore's law and related patterns, ever-smaller form factors have become feasible. Specific technological advances, such as PCI Express, have had a significant design impact, though form factors have historically evolved slower than individual components. Standardization of form factors is vital for hardware compatibility between different manufacturers. Trade-offs Smaller form factors may offer more efficient use of limited space, greater flexibility in the placement of components within a larger assembly, reduced use of material, and greater ease of transportat ...

Smart Glasses
Smartglasses or smart glasses are eye or head-worn wearable computers. Many smartglasses include displays that add information alongside or to what the wearer sees. Alternatively, smartglasses are sometimes defined as glasses that are able to change their optical properties, such as smart sunglasses that are programmed to change tint by electronic means. Alternatively, smartglasses are sometimes defined as glasses that include headphone functionality. A pair of smartglasses can be considered an augmented reality device if it performs pose tracking. Superimposing information onto a field of view is achieved through an optical head-mounted display (OHMD) or embedded wireless glasses with transparent heads-up display (HUD) or augmented reality (AR) overlay. These systems have the capability to reflect projected digital images as well as allowing the user to see through it or see better with it. While early models can perform basic tasks, such as serving as a front end display f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smart Keychain
A keychain () (also keyring) is a small ring or chain of metal to which several keys, or fobs can be attached. The terms keyring and keychain are often used interchangeably to mean both the individual ring, or a combined unit of a ring and fob. The length of a keychain or fob may also allow an item to be used more easily than if connected directly to a keyring. Some keychains allow one or both ends to rotate, keeping the keychain from becoming twisted, while the item is being used. Use of keychains Advertising & Souvenirs Keychains are one of the most common souvenir and advertising items. In the 1950s and 1960s, with the improvement of plastic manufacturing techniques, promotional items including keychains became unique. Businesses could place their names and logos on promotional keychains that were three-dimensional for less cost than the standard metal keychains. Keychains are small and inexpensive enough to become promotional items for larger national companies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
