Answer:
True
Explanation:
If s=abcd is a string defined over {a,b,c,d}, it corresponds to a regular expression which can be represented using a finite automata. Then the reverse of the string essentially corresponds to another finite automata where the starting state becomes the accepting state and vice versa.Moreover all the directions of state transitions will be reversed for each of the transitions in the original automata.
With these modifications, the new finite automata will accept a string which is reverse of the original string ,namely, dcba and this string will ne part of the reverse language.
Answer:
The proof is in the explanation
Explanation:
is
if
for
.
So, basically, we have to solve the following inequality


Dividing everything by
to simplify, we have

I am going to use
. So


There is a solution for the inequality, which proves that
is 
Answer:PART A
(1) Virus attack
(2) Fraud achieved by manipulating records by hackers
(3) Intellectual property theft.
PART B
COMPUTER SYSTEM
PART C
It will hurt the company in the following ways
(1) Loss business opportunities
(2) Increase in cost of operation as it will result in making certain expenses for it to be restored
(3) Loss of work time.
Explanation: Harm is any unanticipated eventualities that are capable of adversely affecting a person or an organisation. Harm can be as a result of theft or loss of certain resources which includes the COMPUTER SYSTEM.
When this loss takes place it can lead to Virus attack,fraud can be achieved by harkers through the manipulation of records, intellectual property theft.
THROUGH THIS HARM THE COMPANY WILL LOSS WORK TIME, LOSS SOME AMOUNT OF MONEY AND SOME BUSINESS OPPORTUNITIES.
Answer:
One's complement = 1 1 0 1 0 0 0 1.
To detect errors, the receiver adds the four words (the three original words and the checksum). If the sum contains a zero, the receiver knows there has been an error. All one-bit errors will be detected, but two-bit errors can be undetected (e.g., if the last digit of the first word is converted to a 0 and the last digit of the second word is converted to a 1).
