In Last class, We learned "what dose 'digital media' mean".


When the new media is come out, it based on the former media(old media).

For instance, the computer file icon, it simulate file shape in the real world.


We talk about tel nelson who is inventor of hypertext.


Hypertext is the way that digital media has been understood new form of writing,

reading, and thinkimg.

Also, we talk about engelbart who is inventer of the mouse, 2d display,

editing, hypermedia & hypermedia e- mail, outline processing,multiple

window displays, document version control, shared-screen teleconferencing,

computer-aided meetings, distributed client-server architecture, virtual terminal

that times people dosen't this creative thinks.

And in this summary, when a medium is new, it is often used to simulate old media.

From these words, I analogize "The old is mother of the news".
