Answer:
The user needs to remove the hard drive and put the hard drive onto the other computer which have already any operating system and antivirus also.
Explanation:
- This gives the facility to extract the information on the other computer.
- Then the user needs to extract the information and files into some hard drive after scanned the files.
- Then the user needs to format the hard drive of the first computer and install the other operating system on it.
- Then the user needs to put any antivirus on his first computer.
- Then the user needs to put the file on the first computer
The above-described steps need to taken for that user if he has the scenario which the above question said. The first steps are to remove the hard drive because the user can not able to read or scan files on that computer so there is a need to transfer the hard disk on the other computer to read and scan files.
Answer:
Given that:
A= 40n^2
B = 2n^3
By given scenario:
40n^2=2n^3
dividing both sides by 2
20n^2=n^3
dividing both sides by n^2 we get
20 = n
Now putting n=20 in algorithms A and B:
A=40n^2
= 40 (20)^2
= 40 * (400)
A= 16000
B= 2n^3
= 2 (20)^3
= 2(8000)
B= 16000
Now as A and B got same on n = 20, then as given:
n0 <20 for n =20
Let us take n0 = 19, it will prove A is better than B.
We can also match the respective graphs of algorithms of A and B to see which one leads and which one lags, before they cross at n= 20.
Correctness is key. The other ones are optimizations at most. Although I would always include humor... ;-)
Answer:
The answers are: it is used to enable fast DNS queries and It can help reduce the amount of network traffic generated by DNS servers.
Explanation:
Because a DNS server can resolve a query from tis local data sends a recursive qyery to a root server.
