Procedure SumEvenOdd(stdin: array [0..100] of integer)
var
i, sum_even, sum_odd: integer;
begin
for i := 0 to 100 do begin
if stdin[i] < 0 then
break;
if stdin[i] mod 2 = 0 then //even number
sum_even := sum_even + stdin[i]
else
sum_odd := sum_odd + stdin[i];
ShowMessage('sum of even is ' + IntToStr(sum_even) + ' ' + 'sum of odd is' + IntToStr(sum_odd) ) ;
end;
end
Answer:
1.) DHCP is sent over the message at UDP.
2.) The address of link-layer is Source: DellComp_4f:36:23 (00:08:74:4f:36:23)
3.) The message type of value to the discover message is 1, but the message type of value to the request packets is 3. This how you can be differentiate two.
4.) The Transaction ID in first four message is 0x3e5e0ce3
The transaction ID in second sets of messages is 0x257e55a3
The transaction ID is identifies if the message is a part of the set of the messages is related to the one transaction
Explanation:
DHCP is stands for the Dynamic Host Configuration Protocol which is the networks management protocol that is used on the UDP/IP networks where by the DHCP servers dynamically assign the IP address and the other networks configuration parameters to the each devices on the network so they can be communicate with the other IP network.
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 .
Answer: The statement implies that the hackers psychologically manipulate the human to access the information they need.
Explanation: The author states that the hacker does not only exploits technology to get system access or to gather information. But there is another pivotal part of hacking. He refers to this part as "social engineering".
Social engineering from information security perspective means manipulate human emotions and convincing them to disclose some confidential information. Hacker often hacks or defrauds after gaining confidence and trust of a person.
Phishing is an example. It is a fraudulent technique for getting some secret information. Phisher sends an email pretending to be from some reputable organization to persuade people to divulge private information like passwords and credit card numbers, ATM card pin etc.
