Answer:

B. Ram

Explanation:

A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer. Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS), machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).

Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.

There are two (2) main types of random access memory (RAM) and these are;

1. Static Random Access Memory (SRAM).

2. Dynamic Random Access Memory (DRAM).

Given a physical host machine that has four quad-core central processing units (CPUs), 16GB of random access memory (RAM), 1TB of hard drive space, and two 1Gbps network interface cards (NICs). Therefore, if we need to create four Windows 2008 servers, the first bottleneck we should upgrade is the random access memory (RAM) because it is typically the working memory that would be used by the server to store data, so they can be accessed easily and rapidly by the central processing unit (CPU).

Hence, the random access memory (RAM) may be increased from 16GB to 64GB or more depending on the client's requirements.

Answer:

import numpy as np

word = input("Enter a word: ")

acc = []

with open("Downloads/record-collection.txt", "r") as file:

   lines = file.readlines()

   for line in lines:

       if word in line:

           line = line.strip()

           acc.append(int(line[0]))

   if np.mean(acc) >= 2:

       print(f"The word {word} is a positive word")

       print(f"{word} appeared {len(acc)} times")

       print(f"the review of the word {word} is {round(np.mean(acc), 2)}")

   else:

       print(f"the word {word} is a negative word with review\

{round(np.mean(acc), 2)}")

Explanation:

The python program gets the text from the review file, using the user input word to get the definition of reviews based on the word, whether positive or negative.

The program uses the 'with' keyword to open the file and created the acc variable to hold the reviews gotten. The mean of the acc is calculated with the numpy mean method and if the mean is equal to or greater than 2 it is a positive word, else negative.

Answer:

- Iterate over the Bellman-Ford algorithm n-1 time while tracking the parent vertex and store in an array.

- Do another iteration and if no relaxation of the edges occurs in the nth iteration then print of return "There are no negative cycle".

- Else, store the vertex of the relaxed edge at the nth iteration with a variable name.

- Then iterate over the vertexes starting from the store vertex until a cycle is found then print it out as the cycle of negative weight.

Explanation:

The Bellman-Ford algorithm can be used to detect a negative cycle in a graph. The program should iterate over the algorithm, in search of a relaxed edge. If any, the vertex of the specified edge is used as a starting point to get the target negative cycle.

d.) black-box testing

Explanation:

Software testing can be regarded as procedures/process engage in the verification of a system, it helps in detection of failure in the software, then after knowing the defect , then it can be corrected. Black Box Testing can be regarded as a type of software testing method whereby internal structure as well as design of the item under test is not known by one testing it. In this testing internal structure of code/ program is unknown when testing the software, it is very useful in checking functionality of a particular application. Some of the black box testing techniques commonly used are; Equivalence Partitioning, Cause effect graphing as well as Boundary value analysis. It should be noted that the purpose of black-box testing is to isolate the behavior of a given component of software.

Answer:

Explanation:

We start from the bottom-most and rightmost internal node of min Heap and then heapify all internal modes in the bottom-up way to build the Max heap.

To build a heap, the following algorithm is implemented for any input array.

BUILD-HEAP(A)

   heapsize := size(A)

   for i := floor(heapsize/2) downto 1

       do HEAPIFY(A, i)

   end for

Convert the given array of elements into an almost complete binary tree.

Ensure that the tree is a max heap.

Check that every non-leaf node contains a greater or equal value element than its child nodes.

If there exists any node that does not satisfy the ordering property of max heap, swap the elements.

Start checking from a non-leaf node with the highest index (bottom to top and right to left).

Answer: a replay attack, a replay attack is used so that the attacker can go sniff out the hash, and get whatever they are trying to get, then once it goes to the attacker it will go back to the original connection after replaying the hash

Hackers use packet sniffing attacks to intercept or steal potentially unprotected data from networks. A network-generated threat is a sniffing attack, also known as a packet sniffing assault. Thus, option D is correct.

Snooping gives ethical hackers a lot of information about how a network functions and how its users behave, which can be used to improve a company's cybersecurity.

Sniffing can, however, be utilized by unscrupulous hackers to conduct catastrophic attacks against gullible targets.

A network sniffer can detect someone using excessive bandwidth at a college or commercial organization and hunt them down.

Therefore, replay attacks are employed so that the attacker can find the hash and obtain the desired object. Once the attacker has received the object, the replay attack causes the object to return to the original connection.

D) Static method

Explanation:

A static method is a method that is created only for the class and not it's instance variables or objects. Such methods can only be accessed by calling them through the class's name because they are not available to any class instance. A static method is created by prefixing the method's name with the keyword static.

A static method cannot be overridden or changed. You create a static method for a block of code that is not dependent on instance creation and that can easily be shared by all instances or objects.

Answer:

A

Explanation:

Vector graphics consist of mathematical descriptions of shapes as a combination of these numerical vectors. Because the vector graphics define the path that the lines should take, rather than a set of points along the way, they can be used to calculate any number of points, and so can be used at any image resolution.

The characteristics of vector graphics are they are based on mathematical/geometric expression. The correct option is A.

Vector graphics are mathematical descriptions of shapes created by combining these numerical vectors. Because vector graphics indicate the course that the lines should travel rather than a set of locations along the way, they may be used to calculate any number of points and thus work at any image resolution.

Raster images generate commonly used image files such as gif, jpeg, jpg, and so on. These can be made with picture editing software such as "Photoshop." Because these work on pixels, when we zoom the image, we can see tiny squares that are nothing more than pixels.

Therefore, the correct option is A, they are based on mathematical/geometric expression.

Explanation:

SQL or structured query language is a database querying language used to communicate or interact with databases. A database query could be as simple as returning all the columns from a database table to complex like joining several query results which in turn forms an algebra expression.

Every query statement or expression is executed with time, execution time needs to be minimized for efficiency, so, a well-arranged and reduced joining in the query improves the efficiency of the query.
