Display deviceA display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). When the input information that is supplied has an electrical signal the display is called an electronic display. Common applications for electronic visual displays are television sets or computer monitors. Types of electronic displaysIn useThese are the technologies used to create the various displays in use today. Liquid-crystal display (L...
PeripheralA peripheral device, or simply peripheral, is an auxiliary hardware device that a computer uses to transfer information externally. A peripheral is a hardware component that is accessible to and controlled by a computer but is not a core component of the computer. It can communicate with a computer through wired or wireless connections. Many modern electronic devices, such as Internet-enabled digital watches, video game consoles, smartphones, and tablet computers, have interfaces for use as a peripheral. Mouses ...
Computer keyboardA computer keyboard is a built-in or peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input method for computers since the 1970s, supplemented by the computer mouse since the 1980s, and the touchscreen since the 2000s. Common designs follow a variety of standard keyboard layouts. Keyboa...
Computer-aided designComputer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software help protect products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or...
TaxiA taxi, also known as a taxicab or simply a cab, is a vehicle for hire that provides point-to-point transportation for passengers typically on an exclusive, non-shared basis. This differs from public transport, where pick-up and drop-off points are set by the service provider, although demand-responsive transport and share taxis provide hybrid bus/taxi modes. Types of vehicles, methods of regulation, hiring, dispatching, and negotiating payment differ from country to country. The main forms of taxi are: Hackney ...
Emergency serviceEmergency services and rescue services are organizations that ensure public safety, security, and health by addressing and resolving different emergencies. Some of these agencies exist solely for addressing certain types of emergencies, while others deal with ad hoc emergencies as part of their normal responsibilities. Many of these agencies engage in community awareness and prevention programs to help the public avoid, detect, and report emergencies effectively. Emergency services are often considered first res...
Package deliveryType of delivery service Package delivery from a UPS truck Package delivery, or parcel delivery, is the delivery of shipping containers, parcels, or high-value mail in single shipments. The service is provided by most postal systems, express mail, private courier companies, and less-than-truckload shipping carriers. Package delivery differs by country due to varying shipping costs and population size. In 2019, for example, China, the United States, and Japan were the top countries in terms of package delivery vo...
DispatcherA dispatcher is a communications worker who receives and transmits information to coordinate operations of other personnel and vehicles carrying out a service. Emergency organizations including police departments, fire departments, and emergency medical services departments as well as civilian organizations such as motorcycle couriers, taxicab providers, trucking companies, railroads, bus systems, and public utility companies, use dispatchers to relay information, direct personnel, and coordinate their operations.
Keyboard technologyModern computer keyboards are input devices designed to support human-machine interaction, where a human user can deliver their commands to a interactive program. The design and making of keyboards is a interdisciplinarity process where multiple fields of science are applied, including engineering, ergonomics, materials science, integrated circuit design, and more. Many different keyboard technologies have been developed to meet consumer demands and optimized for industrial applications. The standard full-size a...
LogisticsLogistics is the part of supply chain management that deals with the efficient forward and reverse flow of goods, services, and related information from the point of origin to the point of consumption according to the needs of customers, and a logistician is a professional working in the field of logistics management.
