Scanning technology |
When you need to get a picture or other data into a computer, a
scanner is an excellent way of doing so. But there are other
scanners besides image scanners.
For example, professionals in law enforcement, fire departments
and other organisations use radio and citizen band (CB) scanners to
communicate. The medical profession uses ultrasound and magnetic
resonance image (MRI) scanners. Stores, shops and supermarkets use
barcode scanners.
The science community uses infra red, spectrometry and other
scanners in astronomy,
chemistry and other disciplines.

Image scanner software
To get the image into a computer you need software.
The scanner usually comes with installation software which takes
care of connecting the scanner to the computer. This involves
installing the TWAIN drivers. To work on the image you can use
almost any graphics or drawing package commercially available. Often one
will be included with the scanner.

Multifunctional scanners
As technology advances with rapid strides, it is
still miniaturising. And we are not talking about
nanotechnology even, but office equipment. Where once we needed
a separate room, then a separate table for a copier, a scanner, a
printer and a fax machine, we now need just the corner of the desk
for all four. Here's a top of the line example.
