A Digital Systemtakes a set of discrete input information
inputs
and discrete internal information
system state
to generates a set of discrete output information

But, what do we mean by discrete elements of information? Any set that is restricted to a finite number of elements contains discrete information.
Examples of discrete sets: The decimal digits
The English alphabet
A
B
Z
The
squares of a chessboard
Discrete elements of information are represented in a digital system by physical quantities called signals.
Electrical signals such as voltages and currents are the most common.
Electronic devices called transistorspredominate in the circuits that implement and manipulate these signals.
The signals in most present
day electronic digital systems use just two discrete values and are therefore said to be binary.
A binary digit, called a bit, has two values:
and
A digital system can be defined as a system that manipulates discrete elements of information
represented internally in binary form." give with solution
