Susan performs a full backup of her server every Sunday at 1:00 a.m. and differential backups on Mondays through Fridays at 1:00 a.m. Her server fails at 9:00 a.m. on Wednesday. How many backups does Susan need to restore
The number of files Susan needs to restore is three because she has full backup and the three files have crashed.
What is differential backup?The most recent, previous complete data backup is used to create a differential backup. Only the data that has changed since the last full backup is captured in a differential backup. The basis of the differential is the full backup that a differential backup is based on.
Susan performs a full backup of her server every Sunday at 1:00 a.m. and differential backups on Mondays through Fridays at 1:00 a.m.
The server crashed on Wednesday at 9:00 am.
Since the Susan has full backup of her data which she did on Sunday at 1:00 am
Differential backups on Monday through Fridays at 1:00 a.m
So the number of files Susan needs to back up is three because the backup file which is taken on Wednesday at 1:00 am has also failed.

If you aren’t familiar with the idea of a leap year, read “Why Is There a Leap Day?” before continuing with the lab.
Your friend is writing a program that will allow the user to input a year and then print “LEAP!” if that year is a leap year or print “not a leap year” if it is not. However, the program isn’t working properly, and your friend asked you for help in debugging.
Before you take a look at the program, you should know these rules for leap years:
A year is a leap year if it can be divided by 400 without a remainder.
A year is a leap year if it can be divided by 4 without a remainder, unless it can also be divided by 100 without a remainder; if that is the case, it is not a leap year.
All other years are not leap years.
Here is your friend’s code:
year=int(input()
if year%400=0:
print("LEAP!")
else:
print(not a leap year")
elseif year%4==0 and year%100!=0
print(“not a leap year")
Note: You may not have seen the % symbol used this way before. It calculates the remainder of the number to the left of it when it is divided by the number to the right of it. So, 10%3 is 1, because when you divide 10 by 3, the remainder is 1.
The correct debugged code is attached below
What is a leap yearA leap year is a year with 366 days and this year occurs once every 4 years. The debugged code line of code of the program written, is as attached below. because the line of code in the question lacks some functions and symbols

Explanation:
This problem has been solved! From the IT Administrator workstation (named ITAdmin), use the tracert command to identify the devices in the path between itself and a remote computer
An IP address is an application programming interface connected to a computer network. There are six routers in the path between IT admin and remote computer.
What is a router?A router is a device that brings the internet service to your linked devices. It is used to forward the data packets on the network channel and also, maintain the traffic of the data on the server.
The default gateway is the IP of the local router that is not routed somewhere else but can be used to manage the router. The default gateway serves as the forwarding host.
Therefore, six routers are placed between the IT admin and the remote computer.

Design, implement and test a Java class that processes a series of triangles. The triangle specification will be identical to that in Programming Assignment #2 (part A). As in that assignment, you will read in the three sides of the triangle, check the input for errors (and handle them if found), classify the triangle and compute its area. For this assignment, triangle data will be read from an input file and the program’s output will be written to another file. The output file will also include a summary of the data processed. You must use at least one dialog box in this program.
The data for each triangle will be on a separate line of the input file, with the input data echoed and the results referred to by the line number (see example).
Some things to note:
• All input data lines must be processed.
• A new line with triangle data always starts with the ‘#’ marker.
• If an error is encountered on a given line, it must be handled. Afterwards, the program will continue on the next line without processing the triangle. An example of such an error is a non-integer appearing in the first three values of a given line.
• Extraneous data must be discarded. This is data that appears after the first three triangle sides are found, but before a new triangle marker is found.
• If the end of file (EOF) is found, a message should be printed out
• There shall be no unhandled file related exceptions and an end-of-file exception must be avoided.
On initialization, the program will prompt the user for both an input and an output file. If a non-existent input file is specified, the appropriate exception must be handled, resulting in an error message. For the exception case, re-prompt the user for the correct input file [Extra credit if you implement a JFileChooser type dialog box]. Once the I/O file is specified, the program will read in and process all the entries in the file. The output of the program will be written to the specified output file and echoed to the console.
The program will evaluate each line and determine the validity of the triangle. If valid, the program will output summary line for the triangle calculation (see Programming Assignment #2A). If invalid, the program will output a description of the error found in the entry. Your program must be robust and handle situations where all the triangle inputs are not proper and/or present.
Once all the entries are processed, a summary will be generated providing the following information:
• Pathname of the input file
• Number of lines processed
• Number of valid triangles
• Number of invalid triangles
You should be able to reuse much of your Programming Assignment #2A code for this project. However, strongly recommend that you rewrite your code and put this functionality in separate method(s). Likewise, any residual problems from #2A should be fixed in this version. The main features you will be adding are:
• Multiple methods
• Exception handing
• File I/O
• Dialog box

When you are trying to anticipate user errors, which do you think is better to use—an if else statement or a try except statement? Why? Can you think of a rule that you could follow to determine which you should use?
Answer:
try except
Explanation:
You shouldn't use an if else statement for anticipating user errors since try-except was made for executing statements until encountering an error, while if-else is checking for a condition and if its not met, it will do an else.

(Python coding)4.3 Code Practice: Question 2
instructions:
Write a program that uses a while loop to calculate and print the multiples of 3 from 3 to 21. Your program should print each number on a separate line.
Expected Output:
3
6
9
12
15
18
21
Answer:
i = 3
while i <= 21:
print(i)
i+=3
Explanation:
First, we will declare i as 3 because otherwise Python will yell at you and say there is no variable with i, we set it to 3 because we will print then increment in the while loop instead of increment then print
Next the while loop, it will go until i is less than or equal to 21 to print from 3 to 21
Then we will print i as an output. The print command will print each number on a separate line
After that we will increment i by 3 to find the next multiple of 3
This solution will print the following:
3
6
9
12
15
18
21
