A DLL is Dynamic Link Library which really is a library of functions that is
shared by multiple programs in Windows. If a programmer writes more than one
program and uses some of the same code it is easier to place the redundant
code in a library member rather than in the individual program. So a DLL
really is a piece of code that can be shared between multiple applications
(programs) at the same time.
Each and every device (peripheral, i.e., keyboard, monitor, printer, CD,
sound card, etc.) connected to a computer needs to be able to communicate
with the CPU (Central Processing Unit) in order that it can function. This
functionality is required in a either one direction or the other called I/O
(input/output). e.g., the keyboard is an input device and the printer is an
output device. Neither can function in the opposite direction. To control
this functionality, each device needs a program (called a driver) that
controls signals (and/or data) sent to/from the CPU and to/from the device.
