Transmit

Transmit is a verb with several related meanings centered on sending or causing something to pass from one place or person to another. It can refer to conveying a message, signal, or energy, or to the act of sending data or information through a channel.

In communications and information technology, to transmit means to send information through a channel using a transmitter. The process involves encoding, modulation, and transmission through media such as air, copper, or fiber, with reception by a receiver. Transmission is described by data rate, bandwidth, latency, and error rates, and can be point-to-point or broadcast, wired or wireless.

In biology and medicine, transmission refers to the spread of an infectious agent from one host to another, or the inheritance of traits from parent to offspring in genetics. Routes include direct contact, droplets, airborne spread, vectors, and fecal–oral routes. Public health aims to reduce transmission through vaccination, hygiene, quarantine, and behavior change.

In physics and engineering, transmission characterizes the passage of energy or waves through a medium or across a boundary. The transmission coefficient quantifies the fraction that passes, and concepts such as impedance matching are used to maximize energy transfer.

In social and cultural contexts, transmission describes the spread of knowledge, beliefs, or practices through teaching, imitation, or media.

Originating from Latin transmittĕre, literally across and to send, transmit has broad application across technology, biology, physics, and society.
