you are an it technician for your company. one of the employees has a computer that continually reboots when it's powered on. he has asked you to fix it. you suspect that the power supply may be failing. which of the following is the best initial step to determine whether the power supply is causing the reboots?
Answers
It is important to address the issue promptly to prevent further damage and ensure the employee's computer is functioning properly.
As an IT technician for the company, the best initial step to determine whether the power supply is causing the continuous reboots is to perform a power supply diagnostic test. This test involves disconnecting all peripherals and components from the computer except for the power supply, motherboard, and CPU. Then, the power supply is connected to a power supply tester, and the voltages are checked to ensure they are within the acceptable range. If the voltages are not within the acceptable range, then the power supply is most likely failing and needs to be replaced.
Alternatively, if a power supply tester is not available, you can try swapping out the power supply with a known good one to see if the issue persists. This will help to confirm whether or not the power supply is the root cause of the problem.
It is important to note that power supply issues can cause various problems with a computer, including unexpected reboots, data loss, and hardware damage. Therefore, it is important to address the issue promptly to prevent further damage and ensure the employee's computer is functioning properly.

two stations running tcp/ip are engaged in transferring a file. this file is 100k long, the payload size is 100 bytes, and the negotiated congestion window size is 300 bytes. the sender receives an ack 1500 from the receiver. • which bytes will be sent next? • answer: bytes 1500 through 1599
Answers
The number of bytes that will be sent or transmitted next is; 1620 bytes
How to find the number of bytes?We are given that:
The file size = 100 KB
The payload size = 100 bytes
The negotiated window size = 300 bytes.
This tells us that the sliding window can only accommodate a maximum number of 300/100 = 3 payloads
The sender receives an ACK 1500 from the receiver.
Total byte of the file is :
1000 KB = 1024000 bytes
The TCP header requires 20 bytes and IPV4 header requires 20 bytes.
Total TCP/IP header is composed of 40 bytes.
Sender receives an ACK 1500 from the receiver and as such the overhead which represents the bytes that will be sent next is;
1500 + (3 * 40)
= 1500 + 120
= 1620 bytes

when both the original file with no hidden message and the converted file with the hidden message are available, what analysis method is recommended by johnson and jajodia?
Answers
Johnson and Jajodia are two renowned researchers who have made significant contributions to the field of steganography. They have proposed various techniques for hiding messages in digital data, such as images, videos, and audio files. In this context, one crucial aspect is to determine whether a given file contains a hidden message or not.
When both the original file with no hidden message and the converted file with the hidden message are available, Johnson and Jajodia recommend using the difference analysis method. This method involves calculating the difference between the original and the converted file and examining the statistical properties of the resulting values. If the values show a deviation from the expected pattern, it is likely that a hidden message is present. The difference analysis method is generally more reliable than other techniques, such as visual inspection or checksum verification.
In conclusion, Johnson and Jajodia's recommendation for analyzing a file with a hidden message when both the original and the converted files are available is to use the difference analysis method. This method can help to detect the presence of a hidden message by comparing the statistical properties of the original and the converted file. It is a reliable technique that can be applied to various types of digital data.

Consider a deep neural net applied to decide between the following four categories: cat, tiger, human face, lion The neural net uses a softmax unit at the output layer. Consider the case where the values fed into the output layer are:cat 0.5 tiger 0.8 human face -3 lion 0.6The softmax converts these values into a probability vector.1. Compute the probabiity vector.2. Which outcome is the most likely?3. Which outcome is the least likely?4. What is the result of cross-entropy cost function if the target output is lion?
Answers
This is how to compute the probability vector using the softmax function, identify the highest and least likely outcomes, and calculate the cross-entropy cost function with a target output.
1. To compute the probability vector, we first apply the softmax function to the input values:
cat: e^0.5 / (e^0.5 + e^0.8 + e^-3 + e^0.6) = 0.239
tiger: e^0.8 / (e^0.5 + e^0.8 + e^-3 + e^0.6) = 0.416
human face: e^-3 / (e^0.5 + e^0.8 + e^-3 + e^0.6) = 0.00021
lion: e^0.6 / (e^0.5 + e^0.8 + e^-3 + e^0.6) = 0.345
So the probability vector is [0.239, 0.416, 0.00021, 0.345].
2. The outcome with the highest probability is tiger, with a probability of 0.416.
3. The outcome with the least likely probability is human face, with a probability of 0.00021.
4. To calculate the cross-entropy cost function with a target output of lion, we first convert the target output to a one-hot vector:
cat: 0
tiger: 0
human face: 0
lion: 1
Then we use the formula for cross-entropy:
-(0*log(0.239) + 0*log(0.416) + 0*log(0.00021) + 1*log(0.345)) = 1.06
So the result of the cross-entropy cost function with a target output of lion is 1.06.

range-based loops are not possible in which of the following languages?
Answers
In a CPU with a k-stage pipeline, each instruction is divided into k sequential stages, and multiple instructions can be in different stages of execution simultaneously. The minimum number of cycles needed to completely execute n instructions depends on the pipeline efficiency and potential hazards.
In an ideal scenario without any hazards or dependencies, each instruction can progress to the next stage in every cycle. Therefore, the minimum number of cycles required to execute n instructions is n/k.However, pipeline hazards such as data hazards, control hazards, and structural hazards can stall the pipeline and increase the number of cycles needed to complete the instructions. These hazards introduce dependencies and conflicts, forcing the processor to wait for certain conditions to be resolved.Therefore, in a real-world scenario with pipeline hazards, the minimum number of cycles required to execute n instructions on a k-stage pipeline would generally be greater than n/k, depending on the specific hazards encountered during execution.
