A computer is presenting a user with a screen requesting payment before the user data is allowed to be accessed by the same user. What type of malware is this?
Answer:
Ransomware
Explanation:
commonly encrypts data on a computer and makes the data unavailable until the computer user pays a specific sum of money.
Final answer:
Ransomware is the type of malware that encrypts user data and requests payment, typically in Bitcoin, to allow the user to regain access. It can affect individuals and businesses, causing significant losses and privacy breaches.
Explanation:
The type of malware described in the question is known as ransomware. This kind of malicious software restricts access to the user's data by encrypting it and then demands payment, usually in the form of cryptocurrencies like Bitcoin, for the decryption key.
Ransomware not only affects individuals but also businesses and can lead to significant financial losses and breach of privacy. Vigilance when clicking on links and managing emails, as well as implementing strong security practices, are critical in preventing such attacks. Once infected, recovery can be difficult and there is no guarantee that paying the ransom will actually restore access to the encrypted data.
What type of IPv6 address should you use when you have multiple routers on a subnet and want hosts to use the nearest router for packets that should be delivered to remote networks?
-Unicast
-Anycast
-Multicast
-Broadcast
Answer:
Anycast
Explanation:
Anycast is linked with the BGP protocol which ensures that all of a router’s neighbors are aware of the networks that can be reached through that router and the topographical distance to those networks. The main principle of anycast is that an IP address range is advertised in the BGP messages of multiple routers. As this propagates across the Internet, routers become aware of which of their neighbors provides the shortest topographical path to the advertised IP address.

a. Try an external device before replacing the motherboard.
b. Make sure you have the correct processor for the motherboard.
c. Verify that the laptop is not under warranty.
d. Determine whether a teardown procedure is available.
Answer: Option(b), (c) and (d) are correct.
Explanation:
According to the question,Sherri should check that process is right for motherboard as incorrect processor may not be able to process instruction and operation successfully and rapidly.
She should also check the warranty of the laptop.If in case , laptop is under warranty then she can get it repaired or replaced as per the policy of laptop company. Tear-down process can be verified so that laptop can be dismantled to investigate the components of processor that is causing issue in processing or other part is responsible for slow execution.Option (a) is incorrect because external devices is attached with motherboard with help of ports and cables.Processor is the actual unit that can cause slow execution and external devices are not responsible for it.Thus, the correct options is option(b),(c) and(d).Final answer:
Sherri should check if her laptop is still under warranty, ensure she has a compatible processor for her motherboard, and locate a guide for the proper teardown procedure before attempting to replace her laptop's processor.
Explanation:
Sherri should consider several factors before attempting to replace the processor on her laptop to address its slow performance. Firstly, she should verify that the laptop is not under warranty. Tampering with the hardware can void the manufacturer's warranty, and if the laptop is still covered, it might be more beneficial to seek professional repairs.
Secondly, it is essential to make sure you have the correct processor for the motherboard. Not all CPUs are compatible with every motherboard due to socket type, chipset, and power requirements. Lastly, Sherri should determine whether a teardown procedure is available to guide her through disassembling and reassembling her laptop safely.
Missing this step could lead to damage to the laptop components or render it completely inoperable when done incorrectly.
Which is true about TCP and UDP? Choose two answers.
TCP is a connection-oriented protocol
TCP is often used in video streaming apps
UDP is often used for sending documents
UDP does not acknowledge a receipt of data
Answer:
TCP is a connection-oriented protocol
UDP does not acknowledge a receipt of data
Explanation:
TCP (Transmission Control Protocol) is a protocol to transfer data, this is one of the most important protocols on the entire internet, this method was implemented from the beginning of the network.
UDP (User Datagram Protocol) this is a protocol faster than TCP because this method doesn't establish a connection to sent data, in this case, always sent data, but TCP is more secure than UDP, and for that UDP is used to transfer music or videos, and TCP websites and database.
UDP doesn't need acknowledgment is done by UDP, is only concerned with speed.
A technician is training a new hire on sealing an RJ-45 connector to the end of an Ethernet cable. Which tool is the technician handing the new hire in order to perform this task?
Cable striper
Crimper
Loopback plug
Punchdown tool
The answer is Crimper.
Crimper is a networking device that would allow RJ-45 pins to get attached to UTP(Unshielded Twister Pair), CATs (Category Ns) and STPs (Shielded Twisted Pair) Cables. These are common type of cables used in computer networking. A crimper looks like a pliers only it has narrow ends with a hole where you would put RJ-45 devices together with the cables. In order to make the cable hold on to the RJ-45, the two hands must be squeezed together with an exact force (not too much force). Once the crimper made a sound, that means, your RJ-45 is now locked with the cables inside.
You must be very careful when using this device. Sometimes crimpers has blades that could peel off cables or cut them for alignment and proper attachments. A pair of gloves and googles are also advisable to wear when you use this device for safety measures.

What is the output of the program below? public class Java1234 { public static void main(String args[ ]) { int matrix[ ][ ]; matrix = new int[3][4]; for(int p = 0; p < 3; p++) { for(int q = 0; q < 4; q++) System.out.prin
Given the complete question to be:
What is the output of the program below?
public class Java1234 {
public static void main(String args[ ]) {
int matrix[ ][ ];
matrix = new int[3][4];
for(int p = 0; p < 3; p++) {
for(int q = 0; q < 4; q++)
System.out.print(matrix[p][q]);
}
}
}
Answer:
000000000000
Explanation:
The output of program will be 0's in twelve places since the line " int matrix[ ][ ];" declared an array of unknown size which will consist of zeros as it's element.
The line "matrix = new int[3][4];" declared the size of the matrix to be 3 by 4 while the for loop printed the elements of the arrays by looping through it.
Actual Question:
What is the output of the program below?
public class Java1234 {
public static void main(String args[ ]) {
int matrix[ ][ ];
matrix = new int[3][4];
for(int p = 0; p < 3; p++) {
for(int q = 0; q < 4; q++)
System.out.print(matrix[p][q]);
}
}
Answer:
000000000000
Explanation:
Going through the code line after line;
=> Line 1
public class Java1234 {
This is just a class declaration where the class name is Java1234. Every program in Java is run in a class
=> Line 2
public static void main(String args [ ] ) {
This is the main method declaration. Execution in Java starts at the main method.
=> Line 3
int matrix [ ][ ];
This is a declaration of a 2 dimensional array matrix to hold integer variables.
=> Line 4
matrix = new int[3][4];
Here the array variable matrix has been initialized to be an array of 3 rows and 4 columns. Therefore, it can hold 12 integer variables.
In Java, when an array is initialized this way, its values assume their default values. And since it is an array of integers, integer variables have a default value of zero(0). Therefore, the array matrix contains 12 integer variables with each value set to 0.
=> Lines 5 through 8
for (int p = 0; p < 3; p++) {
for (int q = 0; q < 4; q++)
System.out.print(matrix[p][q]);
}
This is a nested for loop that cycles through each of the element in the array.
The outer loop goes from 0 to 2 (less than 3). And at each cycle, the inner loop goes from 0 to 3 (less than 4) and prints the array element at the index determined by p and q. i.e
when p = 0, q will go from 0 to 3
=> at p = 0, q = 0, 1, 2, 3
=> for each value of q, the matrix[p][q] will be calculated as follows
matrix[0][0] = 0
matrix[0][1] = 0
matrix[0][2] = 0
matrix[0][3] = 0
when p = 1, q will go from 0 to 3
=> at p = 1, q = 0, 1, 2, 3
=> for each value of q, the matrix[p][q] will be calculated as follows
matrix[1][0] = 0
matrix[1][1] = 0
matrix[1][2] = 0
matrix[1][3] = 0
when p = 2, q will go from 0 to 3
=> at p = 2, q = 0, 1, 2, 3
=> for each value of q, the matrix[p][q] will be calculated as follows
matrix[2][0] = 0
matrix[2][1] = 0
matrix[2][2] = 0
matrix[2][3] = 0
Therefore, the loop will run 12 times altogether and at each cycle, it prints 0 since the array has not been actually initialized with any value and so it assumes its default value which is 0 for an integer.
Output:
000000000000

If your computer requires that you install memory in pairs, it doesn't matter if the two memory modules are the same type, size, or speed.True / False.
Answer:
False
Explanation:
If your computer requires that you install memory in pairs you should always keep in mind that
1. Both are the same type(DDR4+DDR4, DDR3+DDR3, DDR2+DDR2...)
2. Both are the same size (2GB+2GB, 4GB+4GB, 8GB+8GB...)
3. Both are the same speed (800MHz+800MHz, 1666MHz+1666MHz, 3200MHz+3200MHz...)
This is important, because of the predefined slots that are located on the Motherboard.
Although you can change the RAM speed from the BIOS you can not change the predefined slot values
In the Remote Access Domain, if private data or confidential data is compromised remotely, you should set automatic blocking for attempted logon retries.A) True B) False
Answer:
B, False.
Explanation:
Remote access is the ability of a device in a network to achieve a remote connection and control of another system. Its connection is not physical but uses telecommunication or the internet to access systems that cannot be accessed physically.
The RDP or remote desktop protocol is an example of protocols used to remotely access other computers in a network. It connects to the graphical interface of the other computer. When private data is compromised in a remote access, automatic blocking cannot be used to cancel an already established connection, but the system should be shutdown to prevent further exposure.

What is a type of application that allows users to interact with certain stimuli by projecting a realistic graphical representation, often in three dimensions?
Answer:
The application that allows users to do what is stated in the question is known as "Visual Simulation"
Explanation:
Visual simulation otherwise referred to as computer simulation projects a realistic graphical representation as it interacts with a particular stimuli. A very clear example is the popular flight simulator. It can be also used in the medical field and in business.
Going further, visual simulation has been expanded to virtual reality devices that are being used in many ways. Even though, the use of virtual reality devices for visual simulations is on the increase, many people still relate to visual simulation through games. These games project a two-dimensional image to look like a three-dimensional image using advanced graphics.
Individuals who work on visual simulation have some form of degree in engineering precisely, computer engineering. This is because it projects the basics in programming and engineering.
Most programming languages allow you to ask two or more questions in a single comparison by using a(n) ____ operator that joins decisions in a single statement.
Answer:
And is the correct answer for the above question.
Explanation:
And operator is an operator in the programming language which described two decisions in a single statement and it gives true if both the condition defined in the statement is true and it gives false if any of the conditions defined in the statement gives the false result.The above question-statement asked about that operator by which the user can write the two conditions in a single statement. Then the answer is And operator. One example for And operator in c language with if statement is-- if(a>=5&&a<=10), in which && symbols represents AND operator.Logical operators like AND and OR in programming languages allow you to ask two or more questions in a single comparison. The AND operator requires both conditions to be met, while the OR operator requires at least one of the conditions to be met.
Explanation:Most programming languages allow you to ask two or more questions in a single comparison by using a logical operator that joins decisions in a single statement. Logical operators include AND and OR operators. The AND operator (often symbolized as & or &&) allows for two conditions to be met, whereas the OR operator (often symbolized as | or ||) stipulates that at least one of the conditions be met. For example, in the statement if (age > 18 && citizenship == 'American'), both conditions (the age being greater than 18 and the citizenship being American) have to be satisfied due to the AND operator.
