<nettime> More Glossary Items

And more Glossary items from Eduardo Kac:

analog--a method of storing, representing or transmitting information
using continuous variations of a physical quantity that represents (via
analogy) the original; for example, the continuously changing voltage on a
standard telephone line representing the speaker's voice; by contrast,
digital storage, representation, or transmission relies on breaking down
that continuity into discrete numeric units (see digital). 

bandwidth--in broadcasting, it is the frequency range between upper and
lower limiting frequencies (measured in Herz - cycles per second); in
networking, the amount of data that can be carried by a channel (measured
in bits per second). 

Cu-SeeMe--videoconferencing software developed by Cornell University in
1992 and available both for Macintosh and PC platforms. 

freeware--software made available free of charge, usually downloadable
from the Internert. 

haptic feedback--same as tactile feedback; the kind of feedback received
by a remote operator of a device when this device enables him or her to
feel the actual physical texture and shape of tangible objects;  for
example, if the remote operator is wearing a robotic glove and he or she
uses the remote device--say, a robotic hand--and rubs it against
sandpaper, the operator would feel the flat sandpaper texture. 

mediascape--term coined in analogy with the word "landscape"; the term
suggests that we are surrounded no longer by a natural environment, but by
media; it implies that our experience of reality is mediated by mass media
and telecommunications systems; it may also imply that our reality has
become this new communications environment; while the word "landscape"
refers both to an expanse of scenery and its visual representation, the
term mediascape refers exclusively to the mediated environment we inhabit,
and not to any form of pictorial depiction. 

network topology--the spatial configurations and the connectivity systems
of a network. 

personal telepresence--in the Ornitorrinco project, where it originated,
the term is used in analogy with the personal computer, i.e., an
accessible telepresence system used by an individual on the desktop,
usually from one point to another (although multipoint personal
telepresence connections can also be made). 

real time--immediate transmission and reception of a signal as it is
produced by a device, without delays; live television is a common example
of real time transmissions. 

teleoperation--action executed at a distance under remote control.

telerobotics--the field dedicated to the study and development of mostly
non-autonomous robots designed to be remotely manipulated.
