What is a WAN circuit?
Wide Area Network (WAN) is a communication network that covers a large geographic area, such as cities, states and even countries. This type of connection is usually the result of joining smaller networks, such as several LANs (Local Area Networks).
While LANs are able to integrate devices, documents, data, software and hardware in a geographically small space, to facilitate the exchange of information wide area networks (WAN) are able to integrate multiple local area networks. In this way, the integration between devices, documents and important data of a company or institution can take place even between geographically very distant regions.
That being said, to calculate the load it is necessary to multiply users, packets and bits. So:
[tex]5.10.1024 = 51200bps[/tex]
And to calculate the utilization it is necessary to divide load per transmission. So:
[tex]51200/561000 = 0,914[/tex] or 91,4%

Write the function definition for a function called list_total that accepts a list of integers
as a parameter. The function should sum all the numbers in the list and return the total.
Answer:
def list_total(numbers):
sum_of_numbers = 0
for number in numbers:
sum_of_numbers += number
return sum_of_numbers
Explanation:
So, to define a function, the syntax is simply:
def functionName(arguments here):
# code
So to define a function called "list_total" which accepts a list of integers, you write:
"
def list_total(numbers):
# code
"
any the "numbers" is a parameter, and it's just like any variable, so you can name it anything besides keywords. I just named it "numbers" since it makes sense in this context, you could also write "integers" instead and it would be just as valid, and may be a bit more specific in this case.
Anyways from here, the initial sum should be equal to 0, and from there we add each number in the list to that initial sum. This can be done by initializing a variable to the value "0" and then traversing the list using a for loop. This can be done as such:
"
def list_total(numbers):
sum_of_numbers = 0
for number in numbers:
# code
"
So for each element or integer in the list "numbers" the for lop will run, and the variable "number" will contain the value of the current element it's on.
So we can add the "number" to the sum_of_numbers as such:
sum_of_numbers = sum_of_numbers + number
but there is a shorter way to do this, and it's represented as:
sum_of_numbers += sum_of_numbers
which will do the same exact thing. In fact this works for any mathematical operation for example:
a *= 3
is the same thing as
a = a * 3
and
a /= 3
is the same thing as
a = a / 3
It's the same thing, but it's a much shorter and more readable notation.
Anyways, this code will go in the for loop to almost finish the code
"
def list_total(numbers):
sum_of_numbers = 0
for number in numbers:
sum_of_numbers += number
"
The last thing is to return this value, and this is simply done by using the syntax:
"return {value here}"
and since the sum_of_numbers has the value, we write
"return sum_of_numbers"
at the end of the function, which is very very important, because when you use the return keyword, you end the function, and return whatever value is next to the return to the function call
So to finish the code we just add this last piece to get:
"
def list_total(numbers):
sum_of_numbers = 0
for number in numbers:
sum_of_numbers += number
return sum_of_numbers
"
Find a regular grammar that generates the language L(aa*(ab+a)*)
Answer:
S → aAB
A → a | ɛ
B → abB | aB | ɛ
Explanation:
Long time ago I did this, but I think this does the job?
Regular grammar for language L(aa*(ab+a)*):
S -> aA, A -> aA | B, B -> ab | a | ε.
We have,
To construct a regular grammar that generates the language
L(aa*(ab+a)*), we need to break it down into its basic components and then define the production rules for each part.
The language L(aa*(ab+a)) consists of strings that start with one or more 'a's (aa), followed by either the string "ab" or just "a" (ab+a)*.
Note that the "ab+a" part can repeat zero or more times.
Here is the regular grammar:
- Start with the initial non-terminal S.
- The production rules are as follows:
S -> aA
A -> aA | B
B -> ab | a | ε
- Explanation of the production rules:
S -> aA: The string starts with an 'a', followed by A.
A -> aA: If the string contains more 'a's, it remains in A and continues adding 'a's.
A -> B: If the string contains "ab" or just "a", it goes to B.
B -> ab: The string contains "ab".
B -> a: The string contains only "a".
B -> ε: The string is empty.
This grammar generates strings in the language L(aa*(ab+a)*).
The notation "ε" represents an empty string (i.e., the production rule does not add any symbols to the string).
Thus,
Regular grammar for language L(aa*(ab+a)*):
S -> aA, A -> aA | B, B -> ab | a | ε.

In python please:
Assume the variable definitions references a dictionary. Write an ig statement that determined whether the key ‘marsupial’ exist in the dictionary. If so, delete ‘marsupial’ and it’s associated value. If the key is not the dictionary, display a message indicating so.
Answer:
"
if 'marsupial' in dictionary:
del dictionary['marsupial']
else:
print("The key marsupial is not in the dictionary")
"
Explanation:
So you can use the keyword "in" to check if a certain key exists.
So the following code:
"
if key in object:
# some code
"
will only run if the value of "key" is a key in the object dictionary.
So using this, we can check if the string "marsupial' exists in the dictionary.
"
if 'marsupial' in dictionary:
# code
"
Since you never gave the variable name for the variable that references a dictionary, I'm just going to use the variable name "dictionary"
Anyways, to delete a key, there are two methods.
"
del dictionary[key]
dictionary.pop(key)
"
Both will raise the error "KeyError" if the key doesn't exist in the dictionary, although there is method with pop that causes an error to not be raised, but that isn[t necessary in this case, since you're using the if statement to check if it's in the dictionary first.
So I'll just use del dictionary[key] method here
"
if 'marsupial' in dictionary:
del dictionary['marsupial']
else:
print("The key marsupial is not in the dictionary")
"
The last part which I just added in the code is just an else statement which will only run if the key 'marsupial' is not in the dictionary.
In cell N2, enter a formula using the IF function and structured references as follows to determine which work tier Kay Colbert is qualified for:
a. The IF function should determine if the student's Post-Secondary Years is greater than or equal to 4, and return the value 2 if true or the value 1 if false.
The IF Function based formula that can be entered into cell N2 that will return 2 if true, and 1 if false is =IF(M2 >=4, 2, 1).
How is the IF function used?An IF function allows us to be able to sort through data by analyzing data to find out if it conforms to a certain characteristic that we are looking for.
If the data corresponds, the IF function will return a value that means True, but if it doesn't, the value returned would be false.
After typing in the IF function, the next thing to do is specify the cell where the data you want to analyze is. In this case that data is in cell M2. You immediately follow this up by the parameter being compared.
In this case, we want to know if the figure in cell M2 is greater or equal to 4 so the next entry is M2>=
The next entry is the return if the comparison is true. In this case, the number for true is 2 and the one for false is 1. The full formula becomes:
=IF(M2 >=4, 2, 1).
In conclusion, the function is =IF(M2 >=4, 2, 1).
