Often defined in engineering as the instrument from which power is distributed in a motor vehicle, transmission is more broadly understood as something that is transferred or shared. The processes and media of transmission vary: information, knowledge, messages, or sound may be delivered through written and oral communication, or speakers and telecommunication networks (see Avasilichioaei; Boetzkes in SDUK01; Chiang in SDUK08). While transmitted speech has the power to incite social change, and to preserve knowledge and communal identities, it also holds the capacity to spread misinformation (see Okunseinde; Hockaday in SDUK08; Dodd, James, Rosella in SDUK10).
