Describe the facility that allows multiple types of operating systems to run in a virtualized environment with varying types of hardware. Include why this is so difficult and what challenges are overcome.
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.
Which of the following is not true?A. An organization may express its cybersecurity state through a Current Profile to report results or to compare with acquisition requirements.B. Only critical infrastructure agencies may establish a Target Profile that can be used among their constituents as an initial baseline Profile to build their tailored Target Profiles.C. An organization may utilize a Target Profile to express cybersecurity risk management requirements to an external service provider (for example, a cloud provider to which it is exporting data).D. A critical infrastructure owner/operator, having identified an external partner on whom that infrastructure depends, may use a Target Profile to convey required categories and subcategories.
Answer: B. Only critical infrastructure agencies may establish a Target Profile that can be used among their constituents as an initial baseline Profile to build their tailored Target Profiles.
Explanation:
Of the options given in the question, the option that is false is option B "requirements.B. Only critical infrastructure agencies may establish a Target Profile that can be used among their constituents as an initial baseline Profile to build their tailored Target Profiles".

2. Transmission of the weapon to the targeted environment. The three most prevalentdelivery vectors for weaponized payloads by APT actors, as observed by the Lockheed MartinComputer Incident Response Team (LM-CIRT) for the years 2004-2010, are email attachments,websites, and USB removable media.
3. After the weapon is delivered to victim host, exploitation triggers intruders’ code.Most often, exploitation targets an application or operating system vulnerability, but it could alsomore simply exploit the users themselves or leverage an operating system feature that auto-executescode.
4. Installation of a remote access trojan or backdoor on the victim system allows theadversary to maintain persistence inside the environment.
5. Typically, compromised hosts must beacon outbound to anInternet controller server to establish a C2 channel.APT malware especially requires manualinteraction rather than conduct activity automatically. Once the C2 channel establishes, intrudershave "hands on the keyboard" access inside the target environment.

Answer:
Explanation:
This probably means that your browser has saved your username and password into the browser's password manager. This usually occurs the first time you enter your username and password into a new website. The browser will detect this and request to save this information into the password manager. If you agree to do so it will save it and automatically enter this information when opening the site in the future.
If you often purchase items at the same e-tailer and do not have to type in your username and/or password, this probably means your username/password was stored as a COOKIE.
Cookies are small pieces of text (e.g., username/password, website logins, shopping carts, etc) used to identify a computer when using a computer network.Cookies are useful to save you from having to type your own username or password every time.However, these cookies may represent a vulnerability to privacy, although they cannot be used for obtaining personal information from your device.In conclusion, if you often purchase items at the same e-tailer and do not have to type in your username and/or password, this probably means your username/password was stored as a COOKIE.

Pls help I really don’t know
Answer:
Routine decisions are nothing complicated. They are simply decisions that you make everyday, sometimes without thinking, because you've been making them for a long time.
Just relax and think of decisions you made today that you've been making for a long time.
For instance:
Waking up and checking to see if someone texted you. Brushing your teethWhat footwear to wear. What breakfast to have.What time to sleep.Write a function that accepts two pointers; one to the first element and one to the last element of an integer array. The function returns how many numbers are negative in the array. Use only pointer notation.
Answer:
The code to this question can be defined as follows:
int count(int *first, int *last)//defining a method count that accepts two integer pointer
{
int c=0;//defining integer variable c
while (first <= last)//defining a while loop that counts first to last value
{
if (*first < 0)//use if block to check negative value
c++;//increment variable value
first++;//increment first parameter value
}
return c;//return c value
}
Explanation:
In this code, a method "count" is declared that accepts two pointer variable "first and last" as the parameter, inside the method an integer variable "c", and a while loop is declared that counts values, and inside this an if block is used that counts the negative value and increment its value, and also increments the first parameter value, and return c value.

l = Letter("Cain", "Abel")
l.addLine("I am very happy to be writing to you at this joyful moment of my life.")
I.addLine("I am really sorry i killed you, I was a saddist back then.")
print(l.getText())
Explanation:
The Letter class a used to write a letter. The magic method "__init__" is used as a constructor to accept the sender and the recipient of the letter. The addLine method is called on an instance of the class to add string lines to the object while the getText method returns the entire written letter.
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.

Explanation:
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")

_________ 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.
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.
