Text documents that use hypertext markup language allow a user with a web browser to point the mouse arrow to a word that is color highlighted or underlined. 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. For example, a click on these words will send you to the top of this document. Also see this topic elsewhere in the Techno-babble Guide.
Input devices are things like the keyboard or mouse.
Output devices are printers or monitors. A modem is both an input and an output device. A macro is a command that stands for several other commands, thereby condensing a multi-step process into a single step. 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.
