QUESTION: 1

### If two sets, R and T has no elements in common i.e. RÇT=Æ, then the sets are called

Solution:

Two sets are called disjoint if they have no elements in common i.e. RÇT=Æ.

QUESTION: 2

### Which among the following is not a part of the Context free grammar tuple?

Solution:

The tuple definition of context free grammar is: (V, T, P, S) where V=set of variables, T=set of terminals, P=production, S= Starting Variable.

QUESTION: 3

### A context free grammar is a ___________

Solution:

Context free grammar is the set which belongs to the set of context free grammar. Similarly, Regular grammar is a set which belongs to the the set of Context free grammar.

QUESTION: 4

The closure property of context free grammar includes :

Solution:

Context free grammars are closed under kleene operation, union and concatenation too.

QUESTION: 5

Which of the following automata takes stack as auxiliary storage?

Solution:

Pushdown Automaton uses stack as an auxiliary storage for its operations. Turing machines use Queue for the same.

QUESTION: 6

Which of the following automata takes queue as an auxiliary storage?

Solution:

Pushdown Automaton uses stack as an auxiliary storage for its operations. Turing machines use Queue for the same.

QUESTION: 7

A context free grammar can be recognized by

Solution:

A linearly bounded automata is a restricted non deterministic turing machine which is capable of accepting ant context free grammar.

QUESTION: 8

A null production can be referred to as:

Solution:

Null production is always taken as a string in computational theory.

QUESTION: 9

The context free grammar which generates a Regular Language is termed as:

Solution:

Regular grammar is a subset of Context free grammar. The CFGs which produces a language for which a finite automaton can be created is called Regular grammar.

QUESTION: 10

NPDA stands for

Solution:

NPDA stands for non-deterministic push down automata whereas DPDA stands for deterministic push down automata.
