Zenmap is the graphical User Interface representation for
NMAP Security Scanner. It is an open-source program designed to make NMAP easy
for starters to use. Typically, it is used to collect and identify a list of
hosts, OS, as well what services are running on them by using a port scanning
tool. It is used specifically for the scanning and vulnerability phase of
ethical hacking.
A network administrator who wishes to audit all the devices
on a specific IP scheme in a network can use NMAP. The admin can go ahead and
scan the ports to know exactly which ports are closed and which
are opened.
Answer:
Following are the program in the Python Programming Language.
#define function
def Transfer(S, T):
#set for loop
for i in range(len(S)):
#append in the list
T.append(S.pop())
#return the value of the list
return T
#set list type variable
S = ["a","b","c","d"]
#print the values of the list
print(S)
#set the list empty type variable
T=[]
#call the function
T = Transfer(S, T)
#print the value of T
print(T)
<u>Output:</u>
['a', 'b', 'c', 'd']
['d', 'c', 'b', 'a']
Explanation:
Here, we define the function "Transfer()" in which we pass two list type arguments "S" and "T".
- Set the for loop to append the values in the list.
- Then, we append the value of the variable "S" in the variable "T".
- Return the value of the list variable "T" and close the function.
- Then, set the list data type variable "S" and initialize the elements in it and print that variable.
- Finally, we set the empty list type variable "T" and store the return value of the function "Transfer()" in the variable "T" then, print the value of the variable "T".
The correct answer would be Forums
Figure 1: An image — an array or a matrix of pixels arranged in columns and rows.
In a (8-bit) greyscale image each picture element has an assigned intensity that
ranges from 0 to 255. A grey scale image is what people normally call a black and
white image, but the name emphasizes that such an image will also include many
shades of grey.
Figure 2: Each pixel has a value from 0 (black) to 255 (white). The possible range of the pixel
values depend on the colour depth of the image, here 8 bit = 256 tones or greyscales.
A normal greyscale image has 8 bit colour depth = 256 greyscales. A “true colour”
image has 24 bit colour depth = 8 x 8 x 8 bits = 256 x 256 x 256 colours = ~16
million colours.
Answer:
Because of the newly developed biometric technology, the FBI was able to
quickly identify two suspects.
The blurry photos released by the FBI after the bombing prompted
researchers to improve their early biometric software.
Because biometric technology was unavailable at the time, the Boston
Marathon bomber remains at large.
The Boston Marathon bombing made researchers aware of how biometric
technology is sometimes useless and ineffective.
