Number of states of the FSM required to simulate behaviour of a computer with a memory capable of storing "m" words, each of length 'n'
A.  m x 2^{n} 
B.  2^{mn} 
C.  2^{m+n} 
D.  all of these 
Option: B Explanation :
For every data here length is ‘n’ and memory's states are defined in terms of power of 2, Click on Discuss to view users comments. vikki gound said: (11:06am on Thursday 23rd May 2013)
total length m nso required memory=2^m n

An FSM with
A.  1 stack is more powerful than an FSM with no stack 
B.  2 stacks is more powerful than a FSM with 1 stack 
C.  both (a) and (b) 
D.  None of these 
Option: C Explanation : Click on Discuss to view users comments. 
If two finite states machine M and N are isomorphic, then
A.  M can be transformed to N, merely relabelling its states 
B.  M can be transformed to N, merely relabelling its edges 
C.  Both (a) and (b) 
D.  None of these 
Option: A Explanation : Click on Discuss to view users comments. 
Power of
A.  DFSM and NDFSM are same 
B.  DFSM and NDFSM are different 
C.  DPDM and NDPDM are diferent 
D.  Both (A) and (C) 
Option: D Explanation : Click on Discuss to view users comments. Aman said: (8:52pm on Wednesday 26th July 2017)
Because there is an algorithm to convert DFSM to NDFSM and there may or may not be possible DPDM for every NDPDM so both are different

Which of the folowing pairs of regular expressions are equivalent ?
A.  1 (01)* and (10)* 1 
B.  x (xx) * and (xx) * x 
C.  x^{+} and x^{+}x*^{+} 
D.  All of these 
Option: D Explanation : Option (a) and option (b) are similar deriving expressions using rule : (pq)*p = p(qp)* Option (c) will also be valid since: (x+x*+) will be >(xx*)(x*x**) >(xx*)(x*x*) (Using x** = x*) >(xx*)(x*) (Using x*x* = x*) >(xx*) (Using x*x* = x*) >x+ So, the answer will be all of these (Option d) Click on Discuss to view users comments.

I think this ans is wrong as all are true as we expand each and every one all seems are true

As property(PQ)*P = P(QP)* option A and B are also correct... So answer should be D !!!

from the identity rules (PQ)*P=P(QP)* So option A and B also correct so final Option is D.
