Presentation of the data abstracted from the database must take one of two forms: graphs and tabular forms. True False
Answer:
False.
Explanation:
There is also a third way of presenting data. Data can be presented in textual form, using paragraph structures. The other two are using graphs and tabular forms. Presenting data in a graph or pie chart gives a pictorial representation of the data, making the numbers easier to visualize and understand. Using tables also makes data presentation to be easily communicated. Text remains the method for explaining findings, outlining trends, and providing context, a table represents both quantitative and qualitative information, while a graph displays data for comparison.
Write a program using a dictionary that reads in a single positive digit number [0 - 9] from the user at the keyboard. Your program will then be able to look up the digit key in the dictionary and print the digit value spelled out. If the user types in a number that is either more than one digit, negative, or a non int value, re-prompt the user for valid input. First, before demonstrating your test cases, print out a display copy of the key:value pairs in your dictionary in sorted order. Deliverable: yournameLab4.py Your source code solution and a copy of the run pasted into your source submission file. Be sure to comment out your run so that your .py file will still run in the grader test bed. Validate user input is a single positive digit [0 - 9].
Answer:
The program in Python is as follows:
dict = {0:"Zero",1:"One",2:"Two",3:"Three",4:"Four",5:"Five",6:"Six",7:"Seven",8:"Eight",9:"Nine"}
num = input("Number: ")
while(num.isdigit() == False or int(num)<0 or int(num)>9):
num = input("Number: ")
print(dict)
print(dict[int(num)])
Explanation:
#This initializes the dictionary
dict = {0:"Zero",1:"One",2:"Two",3:"Three",4:"Four",5:"Five",6:"Six",7:"Seven",8:"Eight",9:"Nine"}
#This gets input from the user
num = input("Number: ")
#This loop is repeated until the user enters a valid input
while(num.isdigit() == False or int(num)<0 or int(num)>9):
num = input("Number: ")
#This prints the dictionary
print(dict)
#This prints the value of the key
print(dict[int(num)])

describe what happens at every step of our network model, when a node on one network establishes a TCP connection with a node on another network. You can assume that the two networks are both connected to the same router.
Answer:
Each node on the network has an addres which is called the ip address of which data is sent as IP packets. when the client sends its TCP connection request, the network layer puts the request in a number of packets and transmits each of them to the server.

Explanation:
Suppose that TCP's current estimated values for the round trip time (estimatedRTT) and deviation in the RTT (DevRTT) are 350 msec and 10 msec, respectively (see Section 3.5.3 for a discussion of these variables). Suppose that the next three measured values of the RTT are 220 msec, 260 msec, and 390 msec respectively.
(Compute TCP's new value of DevRTT, estimatedRTT, and the TCP timeout value after each of these three measured RTT values is obtained. Use the values of α = 0.125, and β = 0.25. Round your answers to two decimal places after leading zeros.)
What is the estimatedRTT after the first RTT?

GDP measures the production levels of
any nation. Which of the following
automatically improves if a nation's
production improves?
A. Standard of Living
B. Inflation
C. High unemployment
Answer:
A. Standard of Living
Explanation:
Gross Domestic Products (GDP) is a measure of the total market value of all finished goods and services made within a country during a specific period.
Simply stated, GDP is a measure of the total income of all individuals in an economy and the total expenses incurred on the economy's output of goods and services in a particular country. Also, Gross Domestic Products (GDP) is a measure of the production levels of any nation.
Basically, the four (4) major expenditure categories of GDP are consumption (C), investment (I), government purchases (G), and net exports (N).
Hence, the standard of living of the people living in a particular country automatically improves if a nation's level of productivity or production improves; they are able to easily pay for goods and services, as well as save and invest their money.
In contrast, inflation and high unemployment rate are indications of economic downturn, recession and low level of productivity (output) in a country; this would automatically affect the standard of living within such countries.
IN C++
A. Create an abstract base class called Currency with two integer attributes, both of which are non-public. The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part.
B. Create one derived class - Money - with two additional non-public string attributes which will contain the name of the currency note (Dollar) and currency coin (Cent) respectively. DO NOT add these attributes to the base Currency class.
C. In your base Currency class, add public class (C++ students are allowed to use friend methods as long as a corresponding class method is defined as well) methods for the following, where appropriate:
Default Construction (i.e. no parameters passed)
Construction based on parameters for all attributes - create logical objects only, i.e. no negative value objects allowed
Copy Constructor and/or Assignment, as applicable to your programming language of choice
Destructor, as applicable to your programming language of choice
Setters and Getters for all attributes
Adding two objects of the same currency
Subtracting one object from another object of the same currency - the result should be logical, i.e. negative results are not allowed
Comparing two objects of the same currency for equality/inequality
Comparing two objects of the same currency to identify which object is larger or smaller
Print method to print details of a currency object
All of the above should be instance methods and not static.
The add and subtract as specified should manipulate the object on which they are invoked. It is allowed to have overloaded methods that create ane return new objects.
D. In your derived Money class, add new methods or override inherited methods as necessary, taking care that code should not be duplicated or duplication minimized. Think modular and reusable code.
E. Remember -
Do not define methods that take any decimal values as input in either the base or derived classes.
Only the print method(s) in the classes should print anything to console.
Throw String (or equivalent) exceptions from within the classes to ensure that invalid objects cannot be created.
F. In your main:
Declare a primitive array of 5 Currency references (for C++ programmers, array of 5 Currency pointers).
Ask the user for 5 decimal numbers to be input - for each of the inputs you will create one Money object to be stored in the array.
Once the array is filled, perform the following five operations:
Print the contents of the array of objects created in long form, i.e. if the user entered "2.85" for the first value, it should be printed as "2 Dollar 85 Cent".
Add the first Money object to the second and print the resulting value in long form as above.
Subtract the first Money object from the third and print the resulting value in long form as above.
Compare the first Money object to the fourth and print whether both objects are equal or not using long form for object values.
Compare the first Money object to the fifth and print which object value is greater than the other object value in long form.
All operations in the main should be performed on Currency objects demonstrating polymorphism.
Remember to handle exceptions appropriately.
There is no sample output - you are allowed to provide user interactivity as you see fit.

2.13 LAB: Branches: Leap Year
A year in the modern Gregorian Calendar consists of 365 days. In reality the earth takes longer to rotate around the sun. To account for the
difference in time every 4 years a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The
requirements for a given year to be a leap year are:
1) The year must be divisible by 4
2) If the year is a century year (1700 1800. etc.), the year must be evenly divisible by 400
Some example leap years are 600712 and 2016
Wirte a program that takes n a year and determines whether that year is a leap year.
Exif the inputs
1712
Answer:
The program in Python is as follows:
year = int(input("Enter a year: "))
print(year,end=" ")
if year % 4 == 0:
if year % 100 == 0:
if year % 400 == 0: print("is a leap year")
else: print("is not a leap year")
else: print("is a leap year")
else: print("is not a leap year")
Explanation:
This gets input for year
year = int(input("Enter a year: "))
This prints year, followed by a blank
print(year,end=" ")
If year is divisible by 4
if year % 4 == 0:
If yes, check if year is divisible by 100
if year % 100 == 0:
If yes, check if year is divisible by 400; print leap year if true
if year % 400 == 0: print("is a leap year")
print not leap year if year is not divisible by 400
else: print("is not a leap year")
print leap year if year is not divisible by 100
else: print("is a leap year")
print leap year if year is not divisible by 4
else: print("is not a leap year")
Answer:
def is_leap_year(user_year):
if(user_year % 400 == 0):
return True
elif user_year % 100 == 0:
return False
elif user_year%4 == 0:
return True
else:
return False
if __name__ == '__main__':
user_year = int(input())
if is_leap_year(user_year):
print(user_year, "is a leap year.")
else:
print(user_year, "is not a leap year.")

In cell K8, create a formula using the SUM function that calculates the total of range D17:D20 and subtracts it from the value in J8
Answer:
=(J8 - SUM(D17:D20))
Explanation:
Required
Add D17 to D20
Subtract the result from J8
Save the result in K8
To do this, we make use of a nested bracket.
The innermost bracket is to add up D17 To D20 using the sum function.
i.e. SUM(D17:D20)
While the outermost bracket will subtract the calculated sum from J8.
=(J8 - SUM(D17:D20))
The SUM function is used to Adds values, in which users can add different values, in cells or range references or a mix of each of them, and the further calculation can be defined as follows:
In this question, we use the "=(J8 - SUM(D17:D20))" function that's description can be defined as follows:
D17 to D20 AddSubtract the J8 resultSave K8 resultsWe use a nested bracket to do this.D17-D20 is added to the innermost bracket with the sum function.SUM, i.e. (D17:D20)The calculated amount from J8 is taken from the outermost bracket.Therefore the final answer is "=(J8 - SUM(D17:D20))".

Answer:
anywhere in the world
Explanation:
Employee can access information from anywhere in the world. That is the main upside of using cloud-based enterprise system. They run completely remote and are accessible from anywhere as long as you have an internet connection and authorized access to the system. This increased accesibility is crucial for companies that have employees that move from place to place solving problems and solves many of the problems with on-site systems.
Write a function, named FileLineCount(), that returns an integer and accepts a string. Pass the function the file name. It should then use a while loop to return the number of lines in a file. Hint: The function will be reading the file you just created above. g
Answer:
Explanation:
The following code is written in Python. It is a function that accepts a file string and uses that string to read the file in that location. Then it uses a while loop that keeps going until there are no more lines in the file. Each iteration it adds 1 to the count variables. Finally, it prints the count variable which contains the total number of lines in the file. The code has been tested and the output can be seen in the attached image below.
def countLines(file):
file = open(file, 'r')
count = 0
while file.readline():
count += 1
print(str(count) + " total lines")
Argue your points as to wether i.c.t tools in Africa is harmful or helpful to students
Answer: It is helpful.
Explanation:
Access to more information.
ICT tools such as computers and laptops are able to connect to the internet which has a lot more information on most subjects than a student can find in school.
ICT tools will therefore broaden the information base for African students to enable them acquire more knowledge that could aid the continent in catching up to the west.
Skills acquisition.
The world is increasing moving online and this means that those capable of designing online tools and services will be very successful. This is why Jeff Bezos is so rich.
ICT tools in Africa will enable the students learn about these things from a younger age so that they would be able to launch their own online services for the benefit of the continent and the world.
Making schooling more accessible.
For a long time, there has been a shortage of teachers and schools in certain parts of Africa which has led to a lot of children going without education.
Like the Coronavirus pandemic showed us, with ICT tools, a teacher would be able to reach students that are far from them thereby increasing the number of children who can be educated in Africa even with a shortage of teachers and schools.

Explanation:
Variable x will not be in stack as is it a global variable.
Variable i will not be in stack as is it a static variable.
Variable j will be in stack as is it a local variable in the function.
Variable m will be in stack as is it a local variable in the function.
Variable k , a pointer will be in stack as it is in the function bar locally.
What is the difference between ROM and RAM
Answer:
ROM : Read Only Memory.
RAM : Random Ascess Memory.
Answer:
RAM is the random access memory of your computer and ROM, which is a read-only memory.
RAM is a volatile storage memory that temporarily saves your files. ROM is non-volatile memory, which stores your computer instructions permanently.
Explanation:
RAM:-
RAM is a volatile memory that can store data while power is delivered.
It is possible to retrieve and modify data saved on RAM.
It is used to store data that must be processed temporarily by the CPU.
The CPU is able to access the saved data.
It's a memory of high speed.
ROM:-
ROM is a non-volatile memory that can retain information even when power is off.
ROM data can be read-only.
During computer bootstrap, it saves the necessary instructions.
The data stored on it cannot be accessed by the CPU without data being stored in RAM.
It's a lot lighter than RAM.
A school’s administration stores the following data for each student in an online system: name, class, and five electives. Select the data type that the school should use to store information on the electives.
Answer:
Array of Strings
Explanation:
I believe the best data type for this information would be an Array of Strings. This array would have a fixed size of 5 elements. One for each one of the five electives that the student will have. Then the individual electives will be String elements that are saved in the 5 indexes of the Array. This would allow all of the electives to be bundled into a single variable and accessed together or individually by the user. This would be the best and most efficient data type to store this information.

Which tool, first introduced in Windows Server 2008 but remains in Windows Server 2019, provides one location to set up, deploy, and manage servers and server roles
Answer:
Server Manager
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM, Windows Server 2008, Windows Server 2009, etc.
Windows Server 2008 is a Microsoft Windows Server operating system and released to the general public on the 27th of February, 2008, as part of the Windows NT family.
Server Manager is a tool that was first introduced in Windows Server 2008 (OS) but remains in Windows Server 2019 (OS). It was designed and developed by Microsoft to provide end users with one location to set up, deploy, and manage servers and server roles.
On the 14th of January, 2020, Microsoft stopped providing online technical content update, free support options, non-security and free security updates on-premises for Windows Server 2008 and Windows Server 2008 R2, as they have reached the end of their support lifecycle.
