Divide a network 10.10.0.0 with subnet mask 255.255.0.0 into 62 subnets.
10.10.0.0
0000 1010. 0000 1010 . 0000 0000 . 0000 0000
255.255.0.0
1111 1111. 1111 1111 . 0000 0000 . 0000 0000
Required:
a. How many bits do we need to borrow from the host portion?
b. List the lowest and the highest IP address of the first usable subnet.
c. How many usable hosts are there in total before and after subnetting?
Answer:
A. 6 bits
B. lowest IP address is 10.10.0.1 and the highest IP address is 10.10.3.254
C. total number of usable hosts before subnetting = 65534
total number of usable hosts after subnetting = 65408
Explanation:
The IP address 10.10.0.0 with the subnet mask 255.255.0.0 is a class B address with 16 bits of the network address portion and 16 bits of the host portion.
To subnet the address to use 62 subnets (and to reduce the host IP address wasted) 6 bits are borrowed from the host portion of the address to give 2^6 = 64 subnets with two usable host addresses.
The first network address is 10.10.0.0 and the first usable host address of the subnet is 10.10.0.1 making it the lowest address, while the broadcast address is 10.10.3.255 and the address before it becomes the higher address in the network which is 10.10.3.254
The number of usable host of the network before subnetting is 2^16 -2 = 65534, while after subnetting is (2^(16-6) - 2) x 64 = 65408.
What is the last usable host IP address on the 192.168.32.9/30 network?
Answer:
192.168.32.10

which data representation system is based on the digits 0-9 and is mostly easily interpreted In real wrold situations
Answer:
Hexadecimal data representation system is based on the digits 0-9 and is mostly easily interpreted In real word situations .
Explanation:
Hexadecimal manages sixteen different figures: most often the numbers 0–9 to describe values zero to nine, and (A–F) to describe values ten to fifteen. The modern hexadecimal system was first launched into the domain of computing by IBM in 1963. An older description, with 0-9 and u-z, was practiced in 1956 by the Bendix G-15 computer.

Given positive integer num_insects, write a while loop that prints that number doubled up to, but without exceeding 100. Follow each number with a space.
Sample output with input: 8
8 16 32 64
Here's what I havenum_insects = 8 # Must be >= 1print(num_insects, '', end='')while num_insects <= 100 : num_insects = num_insects * 2 print(num_insects,'', end="")This code prints the number 128 even thought the loop is set to end after 100? Why is that?
Answer:
The while loop is executed one more time when num_insects is 64. It gets doubled and 128 gets printed. Then the while loop is not executed anymore since 128 exceeds 100.
So the reason you see 128 is because the multiplication by 2 happens inside the loop before you print. You enter it with 64, but by the time you get to the print statement, it was already multiplied.
The solution is to switch the print and the multiply:
num_insects = 8 # Must be >= 1
while num_insects <= 100 :
print(num_insects,'', end="")
num_insects = num_insects * 2
This has one added advantage that the very first print statement outside the loop can be removed.
Write a function contains_at() that accepts two sequences (e.g., lists, strings, etc), s and q, and an integer p
Answer:
Following are the method to this question:
def contains_at (s, q, p):#defining a method contains_at that accepts a list string and an integer.
Explanation:
In the above-given question, some of the data missing, that's why we define this question as follows:
program for the above the given method:
def contains_at (s, q, p):#defining a method contains_at
return s,q,p #use return keyword to return parameter value
s="data base"#defining string variable
q=[1,2,3,4,5]#defining a list
p=3#defining integer variable
print(contains_at(s,q,p))#use print method to call contains_at method
Output:
('data base', [1, 2, 3, 4, 5], 3)
In the above program, a method contains_at is declared, which accepts a list, string, and an integer value in its parameters, and use the return keyword to return the above parameter value.
In the next step, a parameter variable is declared, which accepts a value, and use a print method to call the method.
The ________ function deletes all elements of the list.
Answer:
clear
clear() :- This function is used to erase all the elements of list.
Explanation:
The clear function deletes all elements of the list. The clear method removes all the elements from a list.
What is a function?Simply said, a function is a “chunk” of code that you may reuse repeatedly rather than having to write it out several times. Programmers can divide an issue into smaller, more manageable parts, each of which can carry out a specific task, using functions.
A list's whole contents are cleared via the clear() method. It returns an empty list after removing everything from the list. No parameters are required, and if the list is empty, no exception is raised. The clear function is present in all languages of computers but has different codes and functions.
Therefore, the list's whole contents are removed by the clear function. All of the elements in a list are removed by the clear method.

Write a program that reads a string from the user containing a date in the form mm/dd/yyyy. If the user entered 12/10/2019, then it should print the date in the form December 10, 2019. solution in python.
Answer:
months = ["January","February","March","April","May","June","July","August","September","October","November","December"]
date = input("mm/dd/yyyy: ")
splitdate = date.split("/")
print(months[int(splitdate[0])-1]+" "+splitdate[1]+", "+splitdate[2]+".")
Explanation:
This line initializes a list of all 12 months
months = ["January","February","March","April","May","June","July","August","September","October","November","December"]
This prompts the user for date
date = input("mm/dd/yyyy: ")
This splits the date into three parts; mm with index 0, dd with index 1 and yy with index 2
splitdate = date.split("/")
The following prints the required output
print(months[int(splitdate[0])-1]+" "+splitdate[1]+", "+splitdate[2]+".")
Analyzing the print statment
splitdate[1] represents the day of the date
splitdate[2] represente the month of the date
However, in months[int(splitdate[0])-1]
First: splitdate[0] represents the month of the year as a string in numeric form e.g. "12", "01"
It is first converted to an integer as: int(splitdate[0])
Then the corresponding month is derived from the month list

Cell address $A$4 in a formula means it is a ___________. *
A. All of the above
B. Mixed cell reference
C. Relative cell reference
D.Absolute cell reference
Answer:
The answer to this question is given below in the explanation section
Explanation:
Cell address $A$4 in a formula means it is an Absolute Cell Reference.
Absolute cell reference does not change when you copy the formula to other cells. when the $ symbol added in the front of the column and row, makes it absolute. It stops the row and column numbers from changing when you copy to other cells. The given $A$4 cell address contains the value in column A and row 4. It does not change the value when you copy the formula that has mentioned ($A$4) into other cells. For example, if you have value 10 at row 4 and column A. Then you multiple column B with A4 cell value and you want that A4 value will not change while copying formula from C1 to C10. You can use in column C1 as =B1*$A$4. Then you copy the formula to cell 10. The value of $A$4 will not change.
while the other options are not correct because:
In the relative cell reference values get changed in the formula, while in the mixed cell reference you can either locked the row or column while the row or column changes when the formula is copied respectively.

Justify Alignment
When you click the Justify button, it displays four options, justify, justify low, justify high and justify medium. You need to select only the justify option. The difference between these options is that low justify creates little space between two words, medium creates a more space than low justify and high creates maximum space between two words to justify the text.
