Asynchronous communication at the data link layer or higher protocol layers is known as statistical multiplexing, for example Asynchronous Transfer Mode (ATM). In this case, the asynchronously transferred blocks are called data packets, for example ATM cells.
In synchronous communications, the stream of data to be transferred is encoded as fluctuating voltage levels in one wire (the 'DATA'), and a periodic pulse of voltage on a separate wire (called the "CLOCK" or "STROBE") which tells the receiver "the current DATA bit is 'valid' at this moment in time".
In physics, the no-communication theorem (also referred to as the no-signaling principle) is a no-go theorem in quantum information theory.It asserts that during the measurement of an entangled quantum state, it is impossible for one observer to transmit information to another observer, regardless of their spatial separation.
The Sociedad Mexicana de Física (SMF) (or Mexican Physics Society) is an association of physicists and other collaborators dedicated to contributing to research in different areas of physics, as well as organizing important national events related to physics, such as the Olimpiadas de Física (Physics Olympics) and the Encuentros de enseñanza (Meetings on teaching).
