Once the mouse button is clicked, the system pulls up the document or site to which the highlighted word was linked. Sometimes this will just move you elsewhere within the same site or it may transfer you across the world to another computer entirely.

It functions like a little program except that it cannot perform any functions that the word processing program or spread sheet program cannot also do. Dummy terminals do not contain the hardware necessary to run the software on the computer but use the mainframe computer's capabilities. Generally mainframes are only used by large organizations or companies that need very sophisticated and extensive computing power.
