Answer:

Option B: DNS

Explanation:

Domain Name Server (DNS) is analogous to a phone book where people can look up a person name through numerical phone number. A DNS server is a database that host a database of public IP addresses (e.g. 64.233.160.0) and their associated hostname (e.g. google.com).

Whenever we type domain name in the address bar of our browser (e.g. google.com), that domain will be delivered to DNS server. Inside DNS server the URL will be mapped with its corresponding IP address making it possible for the web request to reach the the target server.

In python 3.17 LAB: Convert to dollars
krok68 [10]

To convert the inputs to dollars and cents, we make use of a combination of multiplication and addition.

The program written in Python where comments are used to explain each line is as follows:

<em />

<em>#This gets input for the number of quarters</em>

quarters = int(input("Quarters: "))

<em>#This gets input for the number of dimes</em>

dimes = int(input("Dimes: "))

<em>#This gets input for the number of nickels</em>

nickels= int(input("Nickels: "))

<em>#This gets input for the number of pennies</em>

pennies= int(input("Pennies: "))

<em>#This converts the amount to dollars and cents</em>

dollars = quarters * 0.25 + dimes * 0.10 + nickels * 0.05 + pennies * 0.01

<em>#This prints the amount to 2 decimal places</em>

print("Amount ${:.2f}".format(dollars))
