Answer:
d -A
Explanation:
The -S switch is used to use a fake source address, and it can mask your ip.
The -p switch is used to indicate which ports you want to scan, because then it searches for all open ports it searches for that one specifically
The -F switch is used as the quick scan mode, scanning the surface
The -A switch is used to check the operating system.
To achieved a document that is evenly spaced so that they look neat and readable, the option in a word processing program will help to achieve this is the home setting. In the home of the word, you can see there various tabs, one of the tabs is the paragraph. You will click symbol of "justify". And there is simple code to do that, just press the "Ctrl" and "J" on your keyboard at the same time.
Answer:
Explanation:
The dual of a function means replace AND with OR and replace OR with AND.
XOR gate of A , B is

So, Dual of A XOR B is ( replace AND with OR and OR with AND)
Complement of A XOR B is
(In finding compliment AND becomes OR and OR becomes AND ).
By inter changing the above product of terms
Complement of 
So, Dual of A XOR B = Complement of A XOR B.
Answer:
a. 255.255.255.0 (class C)
b. 255.255.255.224
Explanation:
Here, we want to give the implied subnet mask of the given classful IPV4 address
We proceed as follows;
Given IPv4 address: 200.200.200.200
Classes
Class A : 0.0.0.0 to 127.255.255.255
Class B: 128.0.0.0 to 191.255.255.255
Class C: 192.0.0.0 to 223.255.255.255
Class D: 224.0.0.0 to 239.255.255.255
so 200.200.200.200 belongs to Class C and it's subnet mask is 255.255.255.0
In CIDR(Classless Inter Domain Routing)
subnet /27 bits means 27 1s and 5 0s. so subnet
i.e 11111111.11111111.11111111.11100000 which in dotted decimal format is 255.255.255.224 .
