Answer:

Network scan

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.

Generally, a security assessment is carried out by network security experts on a regular basis to determine potential loopholes or vulnerabilities in the information and technology (IT) infrastructure. One of the techniques or approach used in security assessment is a network scan.

A network scan is a security assessment technique used for the automatic detection of host systems on a network. Although a network scan isn't capable of discovering or detecting all the weaknesses on a network, it avails users information about the computer systems that are active on the network and what services the computer systems offer or what ports are available on them.

Write a function named enterNewPassword. This function takes no parameters. It prompts the user to enter a password until the en
zloy xaker [14]

Answer:

def enterNewPassword():

 while True:

   password = input("Enter password: ")

   has_digit = False

   for i in password:

     if i.isdigit():

       has_digit = True

       break

   

   if not has_digit or (len(password) < 8 or len(password) > 15):

     if len(password) < 8 or len(password) > 15:

       print("The password length must be between 8 and 15!")

     if not has_digit:

       print("The password must include at least one digit!")

   else:

     return password

print(enterNewPassword())

Explanation:

*The code is in Python.

Create a function named enterNewPassword that takes no parameter

Create an indefinite while loop. Inside the loop, ask the user to enter the password. Initialize the has_digit as False, this will be used to check if password contains a digit or not. Create a for loop, that that iterates through the password, if one character is digit, set the has_digit as True and stop the loop (Use isdigit() to check if the character is digit or not).

After the for loop, check if has_digit is false or the length of the password is not between 8 and 15. If the length of the password is not between 8 and 15, print the error. If has_digit is false, again print the error.

Otherwise, password met the requirements and return the password

Call the enterNewPassword() function and print the result

Who develop punch card​
monitta

Explanation:

The standard punch card (for computers) was invented and developed by Herman Hollerith. But the idea of punch cards was already long invented, used to control Jacquard looms.

Jacquard looms were looms that used punch cards to control the pattern a loom weaves.

The idea of punch cards in Jacquard looms also influenced Charles Babbage, who decided to use punched cards to control the sequence of computations in his proposed analytical engine. Unlike Hollerith's cards of 50 years later, which were handled in decks like playing cards, Babbage's punched cards were to be strung together.

What is the difference between concrete language and abstract language? give an example of each.
saul85 [17]

The difference between abstract language and abstract language is that abstract language is known through the intellect and concrete language is known through the senses.

<h3>What are abstract and concrete languages?</h3>

The abstract language uses the words like kind, truth, grace, etc. It is a form of language that indicates the intellectual, but concrete language can be known by the senses.

Thus, the distinction between concrete and abstract language is that concrete language is understood via the senses, whereas abstract language is understood through the mind.

Write a program to draw a text-based graph of a mathematical function f(x)
Makovka662 [10]
I have a very good example of the program you need written on Python. You can use this (sorry for bad tabulation):
import math import math def main(): function = input("Enter a function f(x):\n") x = 0 y = 0 for rows in range(10,-11,-1): for col in range(-10,11,1): x=col roundfx = round(eval(function)) if roundfx == rows: print("o", end="") if rows==0 and col==0 and not rows == roundfx: print("+", end="") if col == 0 and not rows == 0 and not rows == roundfx: print("|", end="") if rows==0 and not col==0 and not rows == roundfx: print("-", end="") else: if not rows == 0: if not col == 0: if not rows == roundfx: print(" ", end="") print() main()
