Wireless Application Protocol
Wireless Application Protocol (WAP) is an obsolete technical standard for accessing information over a mobile cellular network. Introduced in 1999, WAP allowed users with compatible mobile devices to browse content such as news, weather and sports scores provided by mobile network operators, specially designed for the limited capabilities of a mobile device. The Japanese i-mode system offered a competing wireless data standard. Before the introduction of WAP, mobile service providers had limited opportunities to offer interactive data services, but needed interactivity to support Internet and Web applications. Although hyped at launch, WAP suffered from criticism. However the introduction of GPRS networks, offering a faster speed, led to an improvement in the WAP experience. WAP content was accessed using a ''WAP browser'', which is like a standard web browser but designed for reading pages specific for WAP, instead of HTML. By the 2010s it had been largely superseded by mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business-to-business
Business-to-business (B2B or, in some countries, BtoB) refers to trade and commercial activity where a business sees other businesses as its customer base. This typically occurs when: * A business sources materials for its production process for output (e.g., a food manufacturer purchasing salt), i.e. providing raw material to the other company that will produce output. * A business needs the services of another for operational reasons (e.g., a food manufacturer employing an accountancy firm to audit their finances). * A business re-sells goods and services produced by others (e.g., a retailer buying the end product from the food manufacturer). Business-to-business activity is thought to allow business segmentation. B2B is often contrasted with business-to-consumer (B2C) trade. Organization Successful B2B operations depend upon sales personnel understanding the purchasing behaviour and outlook of the types of business they wish to work with. B2B involves specific challenges a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business-to-consumer
Direct-to-consumer (DTC or D2C) or business-to-consumer (B2C) is the business model of selling products directly to customers and thereby bypassing any third-party retailers, wholesalers, or middlemen. Direct-to-consumer sales are usually transacted online, but direct-to-consumer brands may also operate physical retail spaces as a complement to their main e-commerce platform in a clicks-and-mortar business model. In the year 2021, direct-to-customer e-commerce sales in the United States were over $128 Billion. Examples of DTC brands currently in business include: Allbirds, Away, Dollar Shave Club, Everlane, Glossier, and Warby Parker. History Direct-to-consumer became immensely popular during the dot-com bubble of the late 1990s when it was mainly used to refer to online retailers who sold products and services to consumers through the Internet.

Point Of Sale
The point of sale (POS) or point of purchase (POP) is the time and place at which a retail transaction is completed. At the point of sale, the merchant calculates the amount owed by the customer, indicates that amount, may prepare an invoice for the customer (which may be a cash register printout), and indicates the options for the customer to make payment. It is also the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. After receiving payment, the merchant may issue a receipt, as proof of transaction, which is usually printed but can also be dispensed with or sent electronically. To calculate the amount owed by a customer, the merchant may use various devices such as weighing scales, barcode scanners, and cash registers (or the more advanced "POS cash registers", which are sometimes also called "POS systems"). To make a payment, payment terminals, touch screens, and other hardware and software options are avail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secure Electronic Transaction
Secure Electronic Transaction (SET) is a communications protocol standard for securing credit card transactions over networks, specifically, the Internet. SET was not itself a payment system, but rather a set of security protocols and formats that enabled users to employ the existing credit card payment infrastructure on an open network in a secure fashion. However, it failed to gain attraction in the market. Visa now promotes the 3-D Secure scheme. Secure Electronic Transaction (SET) is a system for ensuring the security of financial transactions on the Internet. It was supported initially by Mastercard, Visa, Microsoft, Netscape, and others. With SET, a user is given an electronic wallet (digital certificate) and a transaction is conducted and verified using a combination of digital certificates and digital signatures among the purchaser, a merchant, and the purchaser's bank in a way that ensures privacy and confidentiality History and development SET was developed by the SE ...

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet Union, Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996. ''The Economist'' has called DARPA "the agency that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TCP/IP
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). Early versions of this networking model were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to highest, the layers are the li ...

Open System Interconnection
The Open Systems Interconnection (OSI) model is a reference model developed by the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection." In the OSI reference model, the components of a communication system are distinguished in seven abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. The model describes communications from the physical implementation of transmitting bits across a transmission medium to the highest-level representation of data of a distributed application. Each layer has well-defined functions and semantics and serves a class of functionality to the layer above it and is served by the layer below it. Established, well-known communication protocols are decomposed in software development into the model's hierarchy of function calls. The Internet protocol suite as defined in and is a model of net ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
