LOW TECH- A low-tech
device is relatively inexpensive and does not use any electrical components.
Little, training, if any, is needed for low-tech devices.
MID TECH- A mid-tech
device is typically electronic in its nature, and although the cost is
increased, it is still not highly expensive; they too require less training
than high-tech devices.
HIGH TECH- A high-tech
is based on computer technology. These devices are more complicated to operate,
require more training, and are more expensive.
