Answer:
Attached to the keyboard
Explanation:
Touch pad is the type of the mouse that is located on the laptop just near the keyboard or we can say that it is attached to the keyboard of the laptop. It has almost two buttons that are used for the purpose of Left and Right Click.
The touch pad is used to move the cursor to the required position on the screen of the laptop. This will work by just moving figure on the touch pad as the cursor move on the screen in the same direction of the finger..
Analyze the following code:
public class Test {
public static void main(String[] args) {
A a = new A();
a.print();
}
}
class A {
String s;
A(String newS) {
s = newS;
}
void print() {
System.out.println(s);
}
}
Answer:
Constructor issue
Explanation:
When you look at the Class A, the constructor takes one argument as a parameter, a String.
A(String newS) {
s = newS;
}
However, in the main, the constructor does not take any argument as a parameter.
A a = new A();
That's why the code does not compile.
Consider the following sequence of items 10, 36, 25, 54, 37, 12, 75, 68, 42, 86, 72, 90. Insert these items in the order above, into an initially empty implicit binary max-heap. Show the heap throughout the process but write down the heap as an answer after every 3 INSERT() operations. (Just hand-simulate the behavior of the implicit binary max-heap, and draw the resulting heap, both throughout the entire process and the ones after every 3 INSERT() operations as answers (note that the former is to show all your work so that partial credits can be given in case you make mistakes, while the latter (answers) are the ones to be graded). Draw them in the form of a tree rather than an array.)

What attack cracks a password or encryption key by trying all possible valid combinations from a defined set of possibilities (a set of characters or hex values)?
Answer:
Brute Force attack.
Explanation:
A network is a platform where end user devices like computers are connected to communicate and share resources. There are public networks and private networks.
A public network has its end devices and servers configured with a public IP address, which is routable on the internet, while private networks uses private IP addresses which can be used on the internet.
Private networks can be made accessable to public users by configuring an authentication and authorization policy, which could be one or a multi factor authentication. These requires a password and other factors to access the services of a private network.
An attacker can easily access a one factor or a password accessible user account, if the password is weak by using the process called a brute Force attack.
The brute Force attack exploits the vulnerability of weak passwords by entering possible valid combination from a defined set of possibilities.

Explanation:
Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 80 MHz and M2 has a clock rate of 100 MHz. The average number of cycles for each instruction class and their frequencies (for a typical program) are as follows:______
a. Calculate the average CPI for each machine, M1, and M2.
b. Which implementation (M1 or M2) is faster?
c. Find the clock cycles required for both processors.
Answer:
a) the average CPI for machine M1 = 1.6
the average CPI for machine M2 = 2.5
b) M1 implementation is faster.
c) the clock cycles required for both processors.52.6*10^6.
Explanation:
(a)
The average CPI for M1 = 0.6 x 1 + 0.3 x 2 + 0.1 x 4
= 1.6
The average CPI for M2 = 0.6 x 2 + 0.3 x 3 + 0.1 x 4
= 2.5
(b)
The average MIPS rate is calculated as: Clock Rate/ averageCPI x 10^6
Given 80MHz = 80 * 10^6
The average MIPS ratings for M1 = 80 x 10^6 / 1.6 x 10^6
= 50
Given 100MHz = 100 * 10^6
The average MIPS ratings for M2 = 100 x 10^6 / 2.5 x 10^6
= 40
c)
Machine M2 has a smaller MIPS rating
Changing instruction set A from 2 to 1
The CPI will be increased to 1.9 (1*.6+3*.3+4*.1)
and hence MIPS Rating will now be (100/1.9)*10^6 = 52.6*10^6.
You have configured a VPN between your gateway router and another gateway router of the partner organization. You need to ensure that the communication between both the router is encrypted using IPSec. Which type of IPSec configuration are you doing
Answer:
network-to-network
Explanation:
A network-to-network connection requires the setup of IPsec routers on each side of the connecting networks to transparently process and route information from one node on a LAN to a node on a remote LAN.
The information needed for a network-to-network connection include:
• The externally-accessible IP addresses of the dedicated IPsec routers.
• The network address ranges of the LAN/WAN served by the IPsec routers (such as 192.168.1.0/24 or 10.0.1.0/24).
• The IP addresses of the gateway devices that route the data from the network nodes to the Internet.
Final answer:
In configuring a VPN with IPSec for encrypted communication between gateway routers, you are setting up an in-transit encryption using Tunnel mode. This ensures data security from one endpoint to the other and protects against eavesdropping while potentially concealing metadata.
Explanation:
When configuring a VPN between two gateway routers with the requirement of encrypting the communication, you are setting up what is known as an IPSec (Internet Protocol Security) VPN. IPSec ensures that in-transit encryption is applied to the data packets traveling between the routers. This kind of configuration encrypts the data from one VPN endpoint to another, thereby securing the data across the internet or any other intermediary networks.
IPSec can operate in two modes: Transport mode, which encrypts only the payload of each packet leaving the header untouched, and Tunnel mode, which encrypts both the payload and the header which is used in VPNs. In this scenario, you are likely implementing a Tunnel mode configuration to secure the data between the two gateways. This form of encryption ensures that sensitive information being transmitted is hidden from potential eavesdroppers and conceals metadata to a certain extent as well.
Furthermore, end-to-end encryption, or E2EE, is another form of security where only the communicating users can read the messages. In contrast to in-transit encryption, E2EE ensures that the communication provider also cannot access the content. While relevant, E2EE is not specifically about the transport of data between routers in a VPN context.

A 1-line script can be written that counts the number of words in two text files and compares the counts: IF [WC -w f1 -eq WC -w f2] THEN ECHO "equal" ELSE ECHO "not equal" Show the order in which the different tasks below must be performed to accomplish the same goal using a GUI.
Answer:
Hi Salhumad! A GUI for comparing 2 files would have select buttons for choosing the 2 files and a "Compare" button to compare the 2 files once they have been selected.
Explanation:
Your question is giving you most of the answer itself. The 1-line script counts the number of words in two text files and compares the results. Using a GUI, you would have a "select file" chooser button on one side of the screen to allow user to select the first file, and another "select file" button for the user to select the second file for comparison. Another button would be on the screen that would say "Compare files", which once you click, can invoke the one-line script already provided to you in the question. You can put error handling to only call the compare files code once both files are selected.
Assume that a variable hoursWorked has been initialized. Write a statement that assigns the value True to the variable workedOvertime if hoursWorked is greater than 40 and False otherwise.
Answer:
Following are the statement which is given below:
workedOvertime= hoursWorked > 40 //assigns the value to workedOvertime
Explanation:
In this above statement, there is hoursWorked variable which is already initialized There is also another variable "workedOvertime" which assigns the value of the TRUE if the "hoursWorked" is greater then the 40 otherwise it initializes the value FALSE in the "workedOvertime" variable.
The > operator is used for checking the condition that variable "hoursWorked" is greater than 40 or not.
Final answer:
To assign the correct boolean value to the variable workedOvertime, use the statement workedOvertime = hoursWorked > 40; if hoursWorked is greater than 40, workedOvertime is True, otherwise, it is False.
Explanation:
To determine whether an employee has worked overtime and assign the correct boolean value to the variable workedOvertime, you can use a simple conditional statement. Here is how you would write this statement in most programming languages:
workedOvertime = hoursWorked > 40
This statement checks if hoursWorked is greater than 40. If it is, workedOvertime is set to True; otherwise, it is set to False. This is a common task in programming when dealing with pay computations that include overtime pay.
Which one of the following statements is true?
a. In one’s complement format, the leftmost bit is saved for the sign where 1 indicates a negative number and 0 indicates a positive number.
b. The smallest integer that can be represented by a sign-and-magnitude binary number is always 0.
c. It is impossible to store 1610 in 4-bits because overflow will occur. d. The two’s complement representation of +6710 in 8-bits is 1000011.
Answer:
a. In one’s complement format, the leftmost bit is saved for the sign where 1 indicates a negative number and 0 indicates a positive number.
Explanation:
In binary numbers, 1's complement is used to represent the signed binary numbers. In unsigned numbers, there is no need of sign. But in signed binary numbers a signed bit is required. To add the bit that is represent the sign of the number in binary, 0 represents the positive number while 1 represents the negative number.
If we have a number and want to convert it in signed binary number, we just takes it 1's complement and add the signed bit at the left of the number.
E.g.
1 = 0001
is the binary of 1, if we want to add sign, we just add the zero at left most side of the binary which make it positive as given below:
+1 = 0 0001
Now of we want to convert it into negative than, we take 1's complement in which all bits are inverted.
-1 = 1 1110
Final answer:
The correct answer is a. In one's complement format, the leftmost bit indicates the sign, with 1 for negative and 0 for positive numbers.
Explanation:
The true statement among the ones provided is a. In one's complement format, the leftmost bit is indeed saved for the sign where 1 indicates a negative number and 0 indicates a positive number.
b is incorrect because the smallest integer that can be represented by a sign-and-magnitude binary number is -0, which is considered distinct from +0 in this representation method.
c is incorrect because it is certainly possible to store the decimal number 16 (1610) in a 4-bit binary format, specifically as 10000, which does indeed cause overflow if only 4 bits are available, but the claim itself is not expressed as a true standalone statement considering normal binary representations.
d is incorrect because the two's complement representation of +67 (6710) in 8 bits is actually 01000011, not 1000011.

_____ maintains consistency among a set of DFDs by ensuring that input and output data flows align properly. A. Terminating B. Functioning C. Leveling D. Balancing
Answer:
D. Balancing
Explanation:
The concept of balancing states that all the incoming flows to a process and all the outgoing flows from a process in the parent diagram should be preserved at the next level of decomposition. Process decomposition lets you organize your overall DFD in a series of levels so that each level provides successively more detail about a portion of the level above it.
The goal of the balancing feature is to check your system internal consistency, which is particularly useful as different levels of expertise are generally involved in a project.

Always required. b. Necessary when the device would otherwise be the only source of hard-to-replace data, but the backup mechanism must also be secure. c. Never necessary. d. Always detrimental to security, so universally discouraged.
Answer:
The answer is "Option b".
Explanation:
A data backup is a mechanism of generating a duplicate copy from your sensitive files and data like your photos, video clips, documents, and links, for example — so your data is safe and accessible when something occurs to your device, it would be the first to the provider of tough-to-replace data, and it is essential, but its recovery method must be safe, and other choices were wrong that can be described as follows:
In option a, It does not require always, that's why it is wrong. In option c, It is wrong because data backup is necessary. In option d, It doesn't provide detrimental security, that's why it is wrong.The correct answer is b. Necessary when the device would otherwise be the only source of hard-to-replace data, but the backup mechanism must also be secure.
Backing-up is a crucial process to protect data from loss due to deletion, corruption, theft, or viruses. Here are some basic principles:
Back up your data as soon as possible to avoid relying on a single copy for too long.Identify where your primary dataset will be held and develop a strategy for backing up your data to other hard drives or via electronic transmission.Always ensure backups are stored in secure, separate locations to safeguard the data effectively.Utilize cloud storage as an additional backup measure but ensure the data is encrypted to prevent unauthorized access.For portable devices like laptops and smartphones, back up data regularly due to the significant amount of critical information they store.Invest in reliable external hard drives, preferably SSD models, for better reliability and reduced physical damage risk. Ensure compatibility with project computers and never entrust the day's data to anyone without copying it to a secure place first. By following these practices, you can minimize the risk of data loss and ensure that your backups are both reliable and secure.

Other options are not correct according to the following scenario.
This morning when Paul turned on his computer at work, it would not boot. Instead, Paul reported that he heard a loud clicking noise coming from inside his computer.What might be the problem with Paul's computer? Magnetic hard drive failed. hard drive failed. Magnetic hard drive crashed None of these
Answer:
The problem with Paul's computer is that the magnetic hard drive failed.
Explanation:
A magnetic hard drive or hard disk is a non-volatile storage device, which is used to store different information on a computer.
The magnetic disk is made up of numerous magnetic plates, these plates are divided into sectors and tracks. A spindle is present in the middle to rotate the combined plates or the whole unit.
When there is a clicking noise coming from the magnetic disk, it could mean that one of the plates is damaged or if the power to the computer is inconsistent. This can greatly affect the performance of your computer.
Time (non-statistical) division multiplexing differs from frequency division multiplexing because it:
a. does not share a communication circuit
b. splits the communication circuit vertically (with time slots) instead of horizontally
c. increases the wavelength and phase angles of the baseband frequency used for transmission
d. moves the baseband of a circuit by shifting it to a higher frequency
e. reduces baseband signal velocity more than frequency division multiplexing
Explanation:
We can divide the multiplex in different categorize, for example:
FREQUENCY DIVISION MULTIPLEXERS (FDM) TIME DIVISION MULTIPLEXERS (TDM) STATISTICAL TIME DIVISION MULTIPLEXERS (STDM).But in this case, we're going to explain about the time and frequency, because the time division multiplex differ to frequency, because the circuit is divided horizontally, and the time is vertically
b. splits the communication circuit vertically (with time slots) instead of horizontally
