Answer:
C. He can trace the keystrokes used by his friend to log into his account, and then hack it.
Explanation:
A keylogger can be defined as a software program or hardware device designed for monitoring and recording the keystrokes entered by an end user through the keyboard of a computer system or mobile device. A keylogger can be installed as a software application or plugged into the USB port of a computer system, so as to illegally keep a record of all the inputs or keys pressed on a keyboard by an end user.
In this scenario, Ramsay sent a keylogger spyware to his friend's computer. Thus, the likely consequence of this is that he can trace the keystrokes used by his friend to log into his account, and then hack it.
In order to prevent cyber hackers from gaining access to your keystrokes, you should install an anti-malware software application such as Avira, McAfee, Avast, Bitdefender, Kaspersky etc.

Answer:
Robocopy
Explanation:
The newer and most used command to accomplish this is Robocopy. This code does exactly what is described in the question, it copies the entire structure of the volume in question but still maintains all of its permissions and attributes. It also allows you to copy large datasets at an extremely fast speed, roughly 150 MB/sec. Robocopy can even resume interrupted file transfers without loss of data.
The following example demonstrates a program that uses 3 levels of nested dictionaries to create a simple music library. The following program uses nested dictionaries to store a small music library. Extend the program such that a user can add artists, albums, and songs to the library. First, add a command that adds an artist name to the music dictionary. Then add commands for adding albums and songs. Take care to check that an artist exists in the dictionary before adding an album, and that an album exists before adding a song.
music = {
'Pink Floyd': {
'The Dark Side of the Moon': {
'songs': [ 'Speak to Me', 'Breathe', 'On the Run', 'Money'],
'year': 1973,
'platinum': True

is_platinum = bool(input("Is it platinum? True/False"))
music[artist][album] = {}
music[artist][album]['songs'] = song_list
music[artist][album]['year'] = year
music[artist][album]['platinum'] = is_platinum
def add_artist():
artist = input("enter name of artist: ")
if music.get(artist, "no") == "no":
music[artist] = {}
else:
print("artist already exist in dictionary.")
is_album = input("add album? ")
if is_album == "yes":
album_name = input("Enter album name: ")
add_album(artist,album_name)
for _ in iter(dict, 0):
is_exist = input("Do you want to end the program? yes/no: ")
if is_exist == "yes":
break
elif is_exist == "no":
is_art = input("Add artist? ")
if is_art == "yes":
add_artist()
else:
print("enter yes/no")
else:
print("make a decision, yes/no")
Explanation:
The python program defines an "add_artist" and "add_album" function that references the dictionary "music". The functions prompt for user inputs of the artist name, album, year, and platinum record.
The functions use the bracket notation to access and update the dictionary in the memory.
_________ is a variety of mechanisms used to assure the integrity of a data unit or stream of data units.
Answer:
Data integrity.
Explanation:
Data integrity is a variety of mechanisms used to assure the integrity of a data unit or stream of data units.
In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.
Basically, there are four (4) types of integrity constraints and these are;
1. Key constraints.
2. Domain constraints.
3. Entity integrity constraints.
4. Referential integrity constraints.
For example, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.
Hence, any integrity constraint ensures that the relationship between the data in a table is consistent and valid.

In a study to add a new feature to a software program, the programmer introduced two categories, men and women, in the survey she conducted. Is the study observational or experimental
Answer:
Observational
Explanation:
In an observational study, the researcher simply conducts the observation of certain factors without intervening. This is unlike an experimental study where the researcher introduces controls in the research so as to compare the changes between the treated and the untreated groups.
The study above is an observational study because only two groups were surveyed and no control was used in the experiment to compare changes.

Answer:
Server virtualization
Explanation:
The facility or technology which enables multiple types of operating systems to be run together in a virtualized environment with varying types of hardware is called server virtualization.
Just as the name suggests, it involves a server (ie a computer that serves or allows the exchange of data between computers) allowing several different Operating systems (OS) to have their own different configurations.
The fact that the various operating systems will need their individual system configuration presents difficulties and challenges. Also, as the partitioning of the hardware resources has to be done, the server computer memory may become overused.

Modify your previous exercise to determine if the user can ride a rollercoaster. To ride the rollercoaster, you must be at least 42 inches tall. You must also be at least 9 years old. Ask the user how tall and how old they are. Use ONE if-else to determine if the user can ride the rollercoaster. Note how much cleaner this is and how much less repetition this method has.
Answer:
In Python:
age = int(input("How old are you? "))
height = float(input("How tall are you (inches)? "))
if age>=9 and height >= 42:
print("You can ride the roller coaster")
else:
print("You ca'nt ride the roller coaster")
Explanation:
The code segment of the "previous exercise" is not given; so, I rewrite the program from scratch using python.
And using the solution I provided, you'll have an idea of how to write the expected code If the "previous exercise" is not written in python,
This line prompts user for age
age = int(input("How old are you? "))
This line prompts user for height
height = float(input("How tall are you (inches)? "))
This checks if user is at least 9 years old and at least 42 inches tall
if age>=9 and height >= 42:
If true, the user gets to ride the roller coaster
print("You can ride the roller coaster")
else:
If otherwise, the user will not ride the roller coaster
print("You ca'nt ride the roller coaster")

the cause of french revolution and anayze the reason for significane out come
Answer:
The French Revolution, which occurred from 1789 to 1799, was a time in French history when republicans overthrew the monarchy and the Roman Catholic Church went through a period of fundamental restructuring in France. While France swapped back and forth between republic, empire and kingship for 75 years following the fall of the First Republic into the hands of Napoleon Bonaparte, the revolution nevertheless marked the end of the ancient regime and put its followers in the shadows of the imagination of the French people.
The French Revolution began as a protest by the aristocrats against Louis XVI, the king of France and his absolute monarchy, and evolved as a major revolution that changed Europe's history and outlook.
A group called the Girondins, from the Bordeaux area, came to power but was opposed by the Jacobins group. The Jacobins were replaced by the Directoire, a middle-class group that had merged with the Girondins, and a new moderate government was formed. They came to power in 1794 but by 1799 they were considered corrupt and Napoleon took over. Napoleon came to the power with the support of the army and ruled as a tyrant. It was the need for stability and the disposition of the corrupt revolution that made the people willing to accept Napoleon even though he was a dictator. Napoleon brought a new order but many old institutions were also re-established.
In a systems development life cycle (SDLC) model, the purpose of the _____ is to create a physical model that will satisfy all documented requirements for the system.
Answer:
systems design phase.
Explanation:
In a systems development life cycle (SDLC) model, the purpose of the systems design phase is to create a physical model that will satisfy all documented requirements for the system.
This ultimately implies that, that system design involves determining the overall system architecture, which is typically comprised of hardware, end users, physical processing components, software, and the communication channel that will effectively and efficiently satisfy the essential requirements of the system.
The system inputs and outputs will be designed along with a plan of the way the system's features will be navigated.
Basically, system design is divided into two groups;
I. Logical design.
II. Physical design.
The design of service systems is the process involved in planning, creating infrastructure, building communication, organizing staffs and standardization of a system so as to improve its quality and business relationships between the service provider and its clients. A characteristic that can be used to guide the design of service systems is to ensure services cannot be inventoried.
What is true about the process of converting analog data into digital data?
a
To make the digital version be a more accurate representation of the analog data, the process should use fewer bits to represent each sample.
b
The digital version is a representation of the analog data but cannot include all of the details.
c
A longer interval between measured samples means more details will be captured in the conversion from analog to digital
d
The digital version contains all of the details of the analog data, as long as enough storage capacity is available.
Answer:
b. The digital version is a representation of the analog data but cannot include all of the details.
Explanation:
Analog data are continuous infinite stream of data but since the computer has finite memory, these data could only be represented on the computer by converting them to finite data. This process is called analog to digital conversion.
The following are some of the things that should be noted when doing this conversion:
1. Since the digital version is a finite representation of the analog which is infinite, it (the digital version) cannot include all of the details in the analog.
2. For the digital version to be a more accurate version of the analog data it represents, as much bit as possible should be used to represent each sample.
3. Short intervals between measured samples means more details will be captured in the conversion from analog to digital.
Analog to digital conversion of data simply involves the converting an infinite stream of data into a Finite version of the same data.
Digital data are Finite representation of the infinite data typical of analog representation. Hence, a Finite sequence, will not habor all the data or information contained in an analog record.
Therefore, the digital data representation will only be a Finite representation of the analog data and will not contain all of the details.
