Answer:
b. lock screen
Explanation:
Lock screen is a security feature provided by many mobile operating systems in mobile devices. This feature prevents unauthorized access to the device. This feature does not allow the mobile to be used unless the user performs a specific action rightly in order to get access of the mobile device. This action can be entering the correct password, pin-code, pattern. These days, the lock screen with new enhanced security features enables the users to unlock the mobile device using gestures like face recognition and also provides fingerprint lock feature that locks and unlocks the mobile device with the fingerprint of that device user. Its a good practice to set the lock screen in a way that it locks the device if it remains idle for specific time and the user is required to enter the password etc to unlock it. Lock screen is a beneficial feature when it comes to the security of the device and the data stored in it.What type of object is a GUI widget the user can click to select an option, and allows for any number of these objects to be selected at the same time?

Consider an application that transmits data at a steady rate (for example, the sender generates an N-bit unit of data every k time unit, where k is small and fixed). Also, when such an application starts, it will continue running for a relatively long period of time. Answer the following questions, briefly justifying your answer: Would a packet-switched network or a circuit-switched network be more appropriate for this application? Why?
A circuit-switched network would be more appropriate for this application.
Explanation:
The method of Circuit switching helps in the establishment of a network with the nodes that are in communication. The network will be established in the earlier stages before the two nodes starts to communicate with each other. The bandwidth that is essential fro the communication will be reserved and the communication will take place without any interruption.
The example that is given in the question requires a circuit switched network suiting its need. This is because long sessions are essential and there are some needs of bandwidth too. Circuit switched networks helps in this scenario reserving bandwidth for each session of the application and there wont be any wastage. There is also an advantage of ignoring he costs that are related with the setting and disconnecting the circuit connection even if an application has a session with longer time duration.
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

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.

Answer:
Malware
Explanation:
It has the following characteristics:
• They are the most common in the network, and the difference with computer viruses is that they do not need user intervention.
• has the characteristic of replicating itself to expand through the networks to which a device is connected.
• When entering a computer, the worm tries to obtain the addresses of other computers through your contact lists, to infect them as well.
• They do not have to manipulate any program or make the computer malfunction, which makes them a little more difficult to detect.
• Take into account that Malware is "malicious software".
Final answer:
A cyber attack can launch various threats, such as worms and denial-of-service attacks, and involves remote attacks by adversaries accessing devices to steal or exploit data. Botnets are networks of infected computers used for these malicious tasks, while confirmation attacks match web traffic to prove service usage.
Explanation:
A cyber attack is a security threat that may launch a worm through a Trojan horse or launch a denial-of-service attack at a targeted IP address. Cyber attacks are any type of offensive maneuver that targets computer information systems, infrastructures, computer networks, or personal computer devices.
Remote attacks involve adversaries accessing data on devices like phones or laptops through an internet or data connection, often using malware to gain remote access to information. Furthermore, botnets, which are networks of infected computers controlled by a command and control server, can be used to perform malicious tasks such as exploiting network weaknesses or mining for personal data.
When you install an app on one computer or device, it will install automatically on any other computers and devices on the same subscription plan.
This is FALSE.
When you install an app on one computer, you are saving it on a single hard drive. Therefore, only that drive wherein you put and install the application will use and run the application. Otherwise, when you INSTALL IT TOO the whole network, meaning you have to copy and make installation to each computer one by one, then you can distribute the app.
In a relational database, a primary key is sometimes made up of multiple fields. What is this known as?
Answer:
Foreign key is the correct answer for the above question.
Explanation:
A foreign key is a key that is used to extract the information of a foreign table with the help of primary key value. When there is a normalized table then it needs to split on two or more tables to overcome the problem of normalization. So is there is a two table then the primary key is used for the first table and the combination of the primary key and foreign key is used to identify the record of the foreign table. The foreign key is made up of multiple fields because there is no single field in the foreign which can not be null for any instance of the primary table. It happens when there is data for the primary table but there is no record for the foreign table.The above question wants to ask about the term which is made up of multiple fields which is a foreign key which is described as above. Hence Foreign key is the correct answer for the above question.This organization is the largest developer of international standards in the world for a wide variety of products and services.

You and your co-workers are struggling to learn a new software program at work, and you are on a tight deadline to get a report to a major client when your boss decides to step in. Which of the following uses of power by your boss would run counter to the common goals at work?
Answer:
The correct answer is letter "D": announcing that anyone who is not proficient by Friday will be replaced.
Explanation:
In front of problematic situations at work, managers should find a way to solve them even employees' are at fault and they represent the reason for the issue. Putting pressure on them is unlikely to help. In fact, pressing employees will only create a tense environment which could lead to workers making mistakes.
Thus, letting employees know that some of them will be replaced if they are not efficient at doing something at work is counterproductive while pursuing achieving the organization's goals.
The announcing for that anyone who is not proficient till Friday will be a replaced. This option D is correct.
What does a replacement for the Friday mean.?As per the question the coworkers are straggling to learn the new software and work as the deadline reaches the report on the common goals at work.

With this power saving state, open programs and work are saved, and the computer is placed in a state where only the memory and sufficient system files required to start back up are ready to be restored quickly by pressing the power button
Answer:
Sleep mode
Explanation:
Windows stores the data and system settings in temporary memory and then suspends operations when they reach a state that saves power. The screen is blank, and no operations are carried out by the computer.Sometimes referred to as standby or suspend mode, this is a power-saving state that a machine may enter when it is not in use. The systems state is maintained in RAM (random access memory)
memory is a small unit of ultra-fast memory that is used to store recently accessed or frequently accessed data so that the CPU does not have to retrieve this data from slower memory circuits such as RAM.
Answer:
The answer is "Cache memory".
Explanation:
Cache memory, which is specifically created for the circuits of the CPU, that is also called the primary cache, and the secondary cache is called the memory cache contained on an external circuit.

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.
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
"Humans can only hear frequencies up to about 20,000 Hz. To capture audio frequencies that humans can hear, an audio sample rate should be at least double that frequency. Thus, music audio frequency sampling rates should be at least"
Answer:
40,000Hz
-common audio sampling rate is 44,100Hz
Explanation:
the human ear can detect a vibration when it is around 20 Kilo Hertz but could not necessary make meaning out of it, but for the ear to make meaning out the sound the frequency must be up to 40 Kilo Hertz. Music audio frequency sampling rates is at least about 44.1 kilo Hertz this is the common rates for music.
Final answer:
To capture audio frequencies within human hearing range, music audio frequency sampling rates should be at least 40,000 Hz.
Explanation:
Music audio frequency sampling rates should be at least 40,000 Hz to capture audio frequencies that humans can hear. The industry standard for CD recordings is 44.1 kHz (44,1000 Hz), while music studios typically use 48 kHz or higher sample rates.
