A DHCP server receives a request for an IP address from a device when it wants to connect to a network that uses the protocol.
What is DHCP and how does it work?Assigning IP addresses to stationary and mobile hosts that are wired or wirelessly linked is automated using DHCP, a covert process.
A DHCP server receives a request for an IP address from a device when it wants to connect to a network that uses the protocol.
When a device requests help, the server responds by sending an IP address to it. It then keeps track of how the address is being used and returns it after a set amount of time or when the device shuts down.
After that, the IP address is returned to the pool of addresses that the DHCP server manages so that it can be allocated to a different device when it requests network connectivity.
While assigning IP addresses is the protocol's primary role, DHCP also assigns a number of other networking-related settings, such as subnet mask, default gateway, and domain name server (DNS). BOOTP (bootstrap protocol), a predecessor to DHCP that can only be used on IPv4 networks, has been replaced by an IEEE standard called DHCP.

Explanation:
List all of the permutations of {a, b, c} no replacement and length 3
Proof
If subsets, then the answer is correct.Notice that Part 4 * Part 5 = Part 1 6 * 10 = 60
What is permutation example?An arrangement of things in a precise order is called to as a permutation. Here, the members of sets are arranged in a linear or relation to a matter. For illustrate, the set A=1,6 has a permutation of 2, which is 1,6,1. There is no other method for organizing the pieces of set A, as you can see.
1. That would be 5*4*3 = 60
Part 2 is the same as part 3,
just replace every "e" with a "c".
Part 3: correct
For enumerations, it's a good idea to be systematic in doing them,
so you don't miss any.
Alphabetical order would be good
a _ _, d _ _, e _ _
a(de, ed), d (ae, ea), e (ad, da)
ade, aed, dae, dea, ead, eda
Part 4: count the number of permutations in
part 2 or part 3: ? six.
Part 5: "subjects" ? or "subsets"
If subsets, then the answer is correct.

count = count + 1
print("#" + str(count) +": You entered the word " + data)
data = input("Please enter the next word: ")
print("A total of "+ str(count) + " words were entered.")
Explanation:
So the code is asking us to put in words from the user and then it will count those words in total.
so first we want the code to start from 0 to get an accurate count
count = 0
boom, first line.
second you will ask the user to input a word with a data string on it to then have it stored
data = input('Please enter the next word: ')
now if the user enters DONE the code will know to stop and give the total
while data != "DONE":
then we will have the code count the words we inputed,
count = count + 1
next we want to know how many words we put in "the whole point of the code.
print("#" + str(count) +": You entered the word " + data)
the data is very important
if the user didnt enter DONE we want the code to continue so we ask the user to enter another word
data = input("Please enter the next word: ")
now we do the same thing as the code before, now we show how many words were entered in total
print("A total of "+ str(count) + " words were entered.")
