Both Deterministic Finite Automata (DFA) and Nondeterministic Finite Automata (NFA) can be represented using transition tables and state diagrams.

1. Transition Tables:

   a. DFA Transition Table:

   In a DFA transition table, each row represents a state of the DFA, and each column represents a symbol from the alphabet. The entries in the table indicate the next state the DFA transitions to when it reads a particular symbol in a particular state.

   Example DFA Transition Table:

   State	0	1
   q0	q1	q2
   q1	q2	q1
   q2	q0	q2

   This table indicates, for example, that if the DFA is in state q0 and reads the symbol ‘0’, it transitions to state q1.

   b. NFA Transition Table:

   In an NFA transition table, each row represents a state of the NFA, and each column represents a symbol from the alphabet. However, unlike in a DFA transition table, the entries in an NFA transition table can contain multiple next states or even sets of next states for each state-symbol combination.

   Example NFA Transition Table:

   State	0	1
   q0	q0,q1	q1
   q1	q2	q1
   q2	q0,q2	q2

   This table indicates, for example, that if the NFA is in state q0 and reads the symbol ‘0’, it could transition to either q0 or q1.

2. State Diagrams:

   State diagrams visually represent the states, transitions, and accept states of finite automata. In a state diagram:

   • States are represented by circles or nodes.
   • Transitions between states are represented by arrows labeled with input symbols.
   • Accept states (final states) are typically denoted by double circles or some other distinguishing feature.

   a. DFA State Diagram:

   

   In this DFA state diagram:

   • Circles represent states (q0, q1, q2).
   • Arrows represent transitions labeled with input symbols (0, 1).
   • The double circle indicates the accept state (q2).

   b. NFA State Diagram:

   In this NFA state diagram:

   • Circles represent states (q0, q1, q2).
   • Arrows represent transitions labeled with input symbols (0, 1).
   • The double circle indicates the accept state (q2).
   • Note that there are ε-transitions (epsilon transitions) represented by unlabeled arrows. These transitions don’t consume any input symbol and are allowed to take the machine from one state to another.
