   input, stationary, and output.
   input, output, and monitors.
   CPU, monitors, and processing.
   keyboards, monitors, and mice.
Input devices like keyboards, mice, light pens, scanners, bar
code readers, and microphones are used to enter
information. Processing devices transform inputs into
outputs, and output devices like monitors and printers
deliver the information in a usable format

Ergonomics is the science of designing both computer
hardware and work environments to minimize health risks
like repetitive stress injuries. This science has led to a
number of design changes in desks, chairs, monitor size and
angles, and keyboard heights and positions

Binary code or digital data consists of data that has been
converted to a series of 0s and 1s. Each individual 0 or 1 is
a bit, and 8 bits equal a byte, about one typed character.
Petabytes are one quadrillion bytes, exabytes are one
quintillion bytes, and a brontobyte is one sextillion bytes
