Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm (1 1 ⁄ 2 in) or less. NFC offers a low-speed connection through a simple setup that can be used to bootstrap more-capable wireless connections. Like other "proximity card" technologies, NFC is based on …

A universal asynchronous receiver-transmitter (UART / ˈ juː ɑːr t /) is a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable. It sends data bits one by one, from the least significant to the most significant, framed by start and stop bits so that precise timing is handled by the communication channel.

Total Communication (TC) is an approach to communicating that aims to make use of a number of modes of communication such as signed ... History. The term "Total Communication", though, and its specific philosophy, was first used by Roy Holcomb in California. It was adopted by the Maryland school as the official name for their educational ...

In cryptography, a certificate authority or certification authority (CA) is an entity that stores, signs, and issues digital certificates.A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions made about the private key that corresponds to the certified public key.

Publication. The article was the founding work of the field of information theory. It was later published in 1949 as a book titled The Mathematical Theory of Communication (ISBN 0-252-72546-8), which was published as a paperback in 1963 (ISBN 0-252-72548-4).The book contains an additional article by Warren Weaver, providing an overview of the theory for a more general …

Philosophy of history is the philosophical study of history and its discipline.The term was coined by French philosopher Voltaire.. In contemporary philosophy a distinction has developed between speculative philosophy of history and critical philosophy of history, now referred to as analytic.The former questions the meaning and purpose of the historical process whereas the …

Terminology. In the United States, the form World's Record was formerly more common. The term The World's Best was also briefly in use. The latter term is still used in athletics events, including track and field and road running to describe good and bad performances that are not recognized as an official world record: either because it is not an event where the IAAF tracks the record …

The term chat room, or chatroom (and sometimes group chat; abbreviated as GC), is primarily used to describe any form of synchronous conferencing, occasionally even asynchronous conferencing.The term can thus mean any technology ranging from real-time online chat and online interaction with strangers (e.g., online forums) to fully immersive graphical social …

Voice over Long-Term Evolution (VoLTE) is an LTE high-speed wireless communication standard for mobile phones and data terminals, including Internet of things (IoT) devices and wearables. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM.It uses less bandwidth because VoLTE's packet headers are smaller …
