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.

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.

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.

Explanation:

Algorithm is a software which enables the users to solve complex problems with input of commands. The software runs the command inserted and then output is generate. The algorithms can be run parallel and sequentially on more computers.

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.      

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")

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.

Answer:

1. Weaponization.

2. Delivery.

3. Exploitation.

4. Installation.

5. Command and Control (C2).

6. Actions on Objectives.

Explanation:

1. Weaponization: Coupling a remote access trojan with an exploit into a deliverable payload,typically by means of an automated tool (weaponizer). Increasingly, client application data files such as Adobe Portable Document Format (PDF) or Microsoft Office documents serve as the weaponized deliverable.

2. Delivery: Transmission of the weapon to the targeted environment. The three most prevalent delivery 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. Exploitation: 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 also more simply exploit the users themselves or leverage an operating system feature that auto-executes code.

4. Installation: Installation of a remote access trojan or backdoor on the victim system allows the adversary to maintain persistence inside the environment.

5. Command and Control (C2): Typically, compromised hosts must beacon outbound to an Internet controller server to establish a C2 channel.APT malware especially requires manual interaction rather than conduct activity automatically. Once the C2 channel establishes, intruders have "hands on the keyboard" access inside the target environment.

6. Actions on Objectives: only now, after progressing through the first six phases, can intruders take actions to achieve their original objectives. Typically, this objective is data exfiltration which involves collecting, encrypting and extracting information from the victim environment; violations of data integrity or availability are potential objectives as well. Alternatively, the intruders may only desire access to the initial victim box for use as a hop point to compromise additional systems and move laterally inside the network.
