Answer:
David L. Smith
Explanation:
Around March 26, 1999, the Melissa virus was released by David L. Smith
‘Melissa.A’ used social engineering techniques, since it came with the message “Here is the document you asked me for… do not show it to anyone”. In just a few days, she starred in one of the most important cases of massive infection in history, causing damage of more than 80 million dollars to American companies. Companies like Microsoft, Intel and Lucent Technologies had to block their Internet connections due to its action.
How it Works
When opening a document infected with the ‘Melissa.A’, the virus creates an e-mail with the following features:
Subject: Important Message From “sender name”
Text: Here is that document you asked for … do not show anyone else
Attachments: a file with a DOC.
The recipients of this message were the first 50 addresses ‘Melissa.A’ found in the address book in Outlook. This was the first macro virus that used this technique, until this moment there hadn’t been a virus that affected users by sending a Word document within an email.
What Happened
The creator of ‘Melissa.A’, David L. Smith, pleaded guilty but said he did not expect such high economic damage. This malware was created in memory of a topless dancer in Florida with whom he had fallen in love with.
Smith was sentenced to 10 years in prison.
If you print the binary digits just like that, they'll be in the wrong order (lsb to msb). Below program uses recursion to print the digits msb to lsb. Just for fun.
void printBits(unsigned int n)
{
if (n > 1) {
printBits(n >> 1);
}
printf((n & 1) ? "1" : "0");
}
int main()
{
unsigned int number;
printf("Enter an integer number: ");
scanf_s("%d", &number);
printBits(number);
}
Answer:
1)
n = int(input("Please enter the length of the sequence: "))
print("Please enter your sequence")
product = 1
for i in range(n):
val = int(input())
product *= val
print("The geometric mean is: %.4f"%pow(product,1/n))
2)
print("Please enter a non-empty sequence of positive integers, each one is in a separate line. End your sequence by typing done:")
product = 1
val = input()
n = 0
while(val!="done"):
product *= int(val)
n += 1
val = input()
print("The geometric mean is: %.4f"%pow(product,1/n))
Explanation:
This is a question with a much simpler answer given its open ended ness - a representation merely means, given binary data, we can determine what 'thing' that binary data corresponds to.
<span>That makes the question unanswerable, because words can all be represented in binary data, and the question cannot be answered without those. Thus, all answers we can convey have a binary representation of some form (that form being the translation of the words we used to communicate the answer into binary data).</span>
