A sender is an entity, system, or individual that initiates and transmits information, signals, or messages to one or more recipients through a communication channel.

Sender

In communication theory, a sender (also known as the source or transmitter) represents the origin point of any communicative act. This fundamental component initiates the communication process by encoding and transmitting information intended for one or more receiver.

Core Functions

The sender performs several essential functions:

Message Creation
- Formulating the intended content
- Selecting appropriate encoding
- Structuring information for clarity
Channel Selection
- Choosing appropriate communication channel
- Considering medium constraints
- Evaluating environmental factors
Transmission
- Converting thoughts into signals
- Initiating the communication sequence
- Managing transmission timing
