Answer:

DNS server

Explanation:

The Domain name system (DNS) server is a database containing IP addresses and their respective host names. IP addresses are difficult to memorize but domain or host names like srv.myserver are more easy to remember, the DNS servers eliminate the need to memorize this IP addresses. DNS servers are used to translate host names to IP address for web browers because web browsers interact using internet protocol (IP) addresses.

A group of students take hundreds of digital photos for a science project about weather patterns. Each photo file contains data
lesya [120]

Analyzing the metadata would be more appropriate than analyzing the data when: determining the likelihood that the photo was taken at a particular public event.

<h3>What is a data?</h3>

A data can be defined as a representation of instructions or information in a formalized manner, especially as a series of binary digits (bits).

<h3>What is a metadata?</h3>

A metadata can be defined as the data that provides information about one or more aspects of a given data, so as to provide a structured reference that helps to sort and identify all of its attributes such as:

  • Author
  • Date created
  • Date modified
  • File type
  • File size

In this scenario, analyzing the metadata would be more appropriate than analyzing the data when determining the likelihood that the photo was taken or created at a particular public event.

class Customer

class Acco  unt

2) Refine the list to include only the necessary class names for this problem

the class customer is not necessary to solve the problem itself, therefore the only class could be the account class

3) Identify the responsibilities of the class or classes.

The responsibilities of the class account will be

* determination of the type of account--> Acc  ount . type(char)

*  deposit money into the account --> Acc  ount . de posit(float)

* withdraw money into the account --> Acc  ount . with draw(float)

* show balance of the account --> Acc  ount . bal ance()

* generate interest --> Acc  ount . int erest()

Write a pyhton program to calculate area of a circle?
marta [7]

Answer:

The code to calculate the area of a circle is:

from math import pi

def circleArea(radius):

 if radius > 0:

   return pi * (radius ** 2)

 else:

   return None

if __name__ == '__main__':

 radius = 5

 print("Radius: {} Area: {}".format(radius,circleArea(radius)))

Explanation:

A detailed explanation of each line of code is given below.

#Define the number pi used to calculate the area

from math import pi

#We define a function that calculates the area of a circle

def circleArea(radius):

#Check if the radius is valid ( radius > 0) since there aren´t negative radius

 if radius > 0:

#Compute the area formula for a circle \pi * radius^{2}

   return pi * (radius ** 2)

 else:

#Return None if the radius is invalid

   return None

#Run the function we´ve defined

if __name__ == '__main__':

#Define a radius

 radius = 5

#Call the function and parse the radius through it, then print the result

 print("Radius: {} Area: {}".format(radius,circleArea(radius)))
