Human communication was initiated with the origin of speech approximately 100,000 BCE. [1] Symbols were developed about 30,000 years ago. The imperfection of speech allowed easier dissemination of ideas and eventually resulted in the creation of new forms of communication, improving both the range at which people could communicate and the longevity of the information.

The history of electrical signal processing is closely tied to the development of electronic communications technology, beginning in the mid-18th century with the invention of the capacitor, which allowed for the capture and storage of electrical charges.
Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications [1] and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and ...
The history of motion graphics is closely related to the history of computer graphics, as the new developments of computer-generated graphics led to wider use of motion design not based on optical film animation. The term motion graphics originated with digital video editing in computing, perhaps to keep pace with newer technology. Graphics for ...
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
The earliest basic forms of optical communication date back several millennia, while the earliest electrical device created to do so was the photophone, invented in 1880. An optical communication system uses a transmitter , which encodes a message into an optical signal , a channel , which carries the signal to its destination, and a receiver ...
