Layers of media design
According to the text, Inventing the medium, J. Murray describes three layers of media design. These include inscription, transmission and representation. Inscription is the engraving of a message or a code on a medium. Back in the day pen and paper were the common tools for inscription, but today it is done on a digital tablet. Transmission refers to the transfer of message or inscribed codes accross media from sender to receiver. However, in order for the codes to be meaninful to the receiver, it has to be within the context of language and culture of the receiver. This means that for information to achieve the desired result, the designer must consider the variety of his receivers.
