In a selective-reject automatic repeat request (ARQ) error control protocol, the bit error rate (BER) is assumed to be BER= 10 ^-8 and the frames are assumed to be 1000 bits long.
The probability that it will take exactly 11 attempts to transmit a frame successfully is 0.0265. The probability of receiving a frame in error is approximately 0.000125.
Answer: Probability that it will take exactly 11 attempts to transmit a frame successfully= (n-k+1) Pn k (1-P)k-1 where n = 11, k = 1, P = probability of success = (1 - bit error rate) = (1 - 10-8) = 0.99999999.
For 11 attempts, probability that the frame will be transmitted successfully is (11-1) P11 1 (1-P)10= 10 (0.99999999)11-1 (10-8)10= 0.0265Hence, the probability that it will take exactly 11 attempts to transmit a frame successfully is 0.0265.
Probability of receiving a frame in error is given by: P = BER= 10^-8 = 0.00000001.The length of the frame is 1000 bits.
P(Frame has an error) = 1 - P(Frame has no error)= 1 - (1 - P)1000= 1 - (1 - 0.00000001)1000= 1 - 0.99999999^1000= 1 - 0.9048x10^-5≈ 0.000125Thus, the probability of receiving a frame in error is approximately 0.000125.

Explain why the following code snippet is equivalent to that given in the previous problem. x=75 print(x & 1) X = X >> 1 print(x & 1) X = X >> 1 print(x & 1) x= x >> 1 print(x & 1) X = X >> 1 print(x & 1) X = X >> 1 print(x & 1) X = X >> 1 print(x & 1) X = X >> 1 print(x & 1)
The code snippet in the given problem is equivalent to the code snippet in the previous problem because both code snippets are used to calculate the parity of a number in binary form. That is, they are both used to determine if the number has an even or odd number of 1s in its binary representation.
In the code snippet, the following operations are performed:
x=75
print(x & 1) #This line of code uses a bitwise AND operator to check if the least significant bit of x is 1 or 0. If it is 1, then the number is odd; if it is 0, then the number is even.
X = X >> 1 #This line of code shifts all the bits in x one position to the right, effectively dividing it by 2. This is done so that the next least significant bit can be checked.
print(x & 1) #This line of code checks the next least significant bit of x to see if it is 1 or 0.
X = X >> 1 #This line of code shifts all the bits in x one position to the right again.
print(x & 1) #This line of code checks the next least significant bit of x to see if it is 1 or 0.
x= x >> 1 #This line of code is equivalent to the previous line of code and it shifts all the bits in x one position to the right.
print(x & 1) #This line of code checks the next least significant bit of x to see if it is 1 or 0.
X = X >> 1 #This line of code shifts all the bits in x one position to the right again.
print(x & 1) #This line of code checks the next least significant bit of x to see if it is 1 or 0.
X = X >> 1 #This line of code shifts all the bits in x one position to the right again.
print(x & 1) #This line of code checks the next least significant bit of x to see if it is 1 or 0.
The reason why this code snippet is equivalent to the previous problem is that the previous problem also calculated the parity of a number in binary form. The only difference is that the previous problem did not use bit manipulation operators to perform the calculation. Instead, it used a loop and division by 2 to shift the bits to the right.

Explain differences between registers and RAM and why we have
them separated.
Registers are faster than RAM, hold smaller amounts of data, and are located in the CPU, while RAM is larger, slower, and holds more data, and is separate from the CPU.
Registers and Random Access Memory (RAM) are both types of computer memory with unique functions. Registers are small amounts of memory located inside the Central Processing Unit (CPU), while RAM is a much larger, slower type of memory, located outside the CPU. Registers can hold data or instructions that the CPU needs to access quickly, making them much faster than RAM.
They are used to store temporary data that is frequently used by the CPU, such as the memory address of an instruction in RAM. They also hold the CPU's current state, including the value of all of its registers and program counters. RAM, on the other hand, is much slower than registers, but can hold much larger amounts of data. RAM is used to store programs and data that are not currently being used by the CPU, but may be needed in the near future.
This allows the CPU to access the information quickly when it is needed, rather than having to retrieve it from slower storage devices like hard drives. Having registers and RAM separated is necessary because of their different purposes and speeds. Registers are used to quickly access frequently used data and instructions, while RAM is used to store larger amounts of data that is not currently in use. Having separate memory types allows for more efficient use of the CPU's resources.

Total active pressure,
P = Ka . . H² = 0.5 . . H² . (1 + sin )² . tan²(45° + '/2)
Here, Ka = Active earth pressure coefficient
P = 0.5 × 18 × 8.5² × (1 + sin 10)² × tan² (45 + 33/2)P
= 264.5264 kN/m
The resultant pressure will be perpendicular to the back of the wall. Let’s calculate the location of the resultant pressure by taking moments about point A on the back of the wall, where the base of the wall meets the ground:
[tex]\tan{\theta} = \dfrac{1 - \sin{\varphi}}{1 + \sin{\varphi}}[/tex]
= (1 - sin 35) / (1 + sin 35)
= 0.36345
∴ = tan⁻¹ 0.36345 = 20.7°
Now, let’s calculate the distance of the line of action of the resultant pressure from point A:
Ka = (tan²(45° + '/2)) / (tan²(45° + w/2))
= (tan²(45° + 33/2)) / (tan²(45° + 20/2))
= 2.297
∴ [tex]\frac{1 - \sin{\theta}}{1 + \sin{\theta}}[/tex]
= Ka / (2 + Ka)
= 0.5263
∴ sin = (1 - 0.5263) / (1 + 0.5263)
= 0.2103
∴ = sin⁻¹ 0.2103 = 12.2°
∴ d = (8.5 / 3) (1 + 2 / Ka) sin d
= (8.5 / 3) (1 + 2 / 2.297) sin 12.2°d
= 2.2258 m

Please explain why Von-Neumann architecture adopts separated memory and processor as its programming model. (6 points)
The Von-Neumann architecture adopts separated memory and processor as its programming model due to several reasons. This architecture is designed to function using a series of instructions, which are processed by the computer.
There are three critical parts of a Von-Neumann machine: the central processing unit (CPU), the memory, and the input/output devices. The CPU is the central hub of a Von-Neumann machine, responsible for interpreting and executing instructions that have been stored in the memory. The CPU can fetch an instruction from memory, process it, and then store the result back in memory.
One of the primary reasons that the Von-Neumann architecture uses a separate memory and processor is to allow for more efficient use of resources.
By separating the memory and processor, the computer can dedicate its processing power solely to executing instructions, while the memory stores all of the instructions and data necessary for the program to run. This allows the computer to perform more tasks in a shorter amount of time, as the CPU is not bogged down by memory management tasks.
Another important reason for the separation of memory and processor in Von-Neumann architecture is to make the programming model more accessible and easier to use.
The Von-Neumann architecture uses a sequential programming model, which means that instructions are processed one at a time, in the order they are received. This makes it easier for programmers to write and debug code since they do not have to worry about complex memory management or other low-level details.
In conclusion, the Von-Neumann architecture adopts separated memory and processor as its programming model due to its efficiency and simplicity. The separation of memory and processor allows for more efficient use of resources and makes the programming model more accessible to developers.

In your dorm room, you have two 100W lights, a 150W Q-LED TV, a 540W refrigerator, a 1200 W dishwasher, and a 50W laptop computer. If there is a 15A circuit breaker in the 120V power line, the breaker will trip. We need to find the total current through the circuit so we can check that the circuit will trip or not.
A circuit breaker is an automatically operated electrical switch that is designed to protect an electrical circuit from damage due to excess current from an overload or short circuit. A 15A circuit breaker is capable of handling a maximum of 15 Amperes of current. For it to trip, the current through the circuit must exceed 15 A.To determine whether the 15A circuit breaker will trip, add the power ratings of all the devices in the room:
Total power= 2 x 100W + 150W + 540W + 1200W + 50W= 2090W
Since the power rating is given in watts, we can convert watts to amperes using the formula below:
P = VI.
where P is power, V is voltage, and I is current.
I = P/V = 2090/120 = 17.42 A
This means the current through the circuit is 17.42 A, which exceeds the capacity of the circuit breaker. Therefore, the circuit breaker will trip.

int recWidth
int recHeight
Calculate the areas of each shape and store the values in the following variables:
sqArea
recArea
Output the dimensions and areas of each shape as shown in the Example Run.
Formulas:
Square: Remember that since all sides of a square are the same length, the area of a square is any of its sides multiplied by itself.
Rectangle: The area for a rectangle is width * height.
Example Run
Please enter the width of the square:
5
Please enter width of the rectangle:
4
Please enter height of the rectangle:
10
The area of a square with a width of 5 is 25.
The area of a rectangle with a width of 4 and a height of 10 is 40.
The given task requires writing a program that prompts the user for the width of a square, the width of a rectangle, and the height of a rectangle. The program should calculate the areas of each shape and output the dimensions and areas.
Here is a possible implementation in Java:
```java
import java.util.Scanner;
public class ShapeAreaCalculator {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Please enter the width of the square:");
String input = scanner.nextLine();
int sqWidth = Integer.parseInt(input);

Use recursive functions only
Python only**
transcriptionErrors - Given two sequences, one of RNA and one of DNA, looks for transcription errors where the base in the RNA sequence doesn't match the base in the DNA sequence. Each RNA base is supposed to be transcribed from a particular DNA base (for example, the DNA base 'A' becomes the RNA base 'U'), but sometimes errors occur in this process. Given an RNA sequence and the DNA it came from, any place where the corresponding bases aren't paired (according to the templateBase function) is a transcription error. This function must return the number of transcription errors evident in the given RNA and DNA pair. For this function, you may NOT assume that the two strings provided will always be the same length, and if one is longer, in addition to counting errors in the portion where they overlap, each extra base in the longer string should count as an error, although we will only test this as an extra goal.
Define transcriptionErrors with 2 parameters
Use def to define transcriptionErrors with 2 parameters
Do not use any kind of loop
Within the definition of transcriptionErrors with 2 parameters, do not use any kind of loop.
Use a return statement
Within the definition of transcriptionErrors with 2 parameters, use return _ in at least one place.
Call transcriptionErrors
Within the definition of transcriptionErrors with 2 parameters, call transcriptionErrors in at least one place.
example:
In [ ]: transcriptionErrors('AAA','TTC')
Out[ ]: 1
Given two sequences, one of RNA and one of DNA, the transcription errors occur where the base in the RNA sequence does not match the base in the DNA sequence. Each RNA base is supposed to be transcribed from a particular DNA base, but sometimes errors occur in this process. .Finally, we return the error count obtained from the recursive calls.
The function transcriptionErrors has to return the number of transcription errors evident in the given RNA and DNA pair.For this function, we have to use recursive functions only. Python only. Here's the implementation of the transcriptionErrors function:
Firstly, we define the template base function. It takes a base from the DNA sequence and returns the corresponding base from the RNA sequence. This function is used to check if the RNA sequence is transcribed correctly from the DNA sequence.Next, we define the transcriptionErrors function that takes two arguments - dna_seq and rna_seq. This function recursively counts the number of transcription errors in the given DNA and RNA sequences. If the length of the rna_seq is 0, we return 0. If the length of the dna_seq is 0, we return the length of the rna_seq multiplied by 2, as every extra base in the rna_seq should count as an error.

If a MicroBit requires taking 68ms to do analog-to-digital conversion and 32ms to calculate and display the mean value of 5 consecutive samples before performing the next sampling, determine the maximum sampling frequency that the MicroBit can perform? 5kHz 10kHz 20kHz 2.5kHz
the maximum sampling frequency that the MicroBit can perform is 10kHz.
In order to determine the maximum sampling frequency that the MicroBit can perform, it is essential to determine the total time required by each sample, including the analog-to-digital conversion and the calculation and display of the mean value of five consecutive samples before performing the next sampling.
This time is equal to the sum of the analog-to-digital conversion time and the time required to calculate and display the mean value of five consecutive samples.
Using the information given, we can calculate the time required for each sample as follows:
Time per sample = Analog-to-digital conversion time + Time to calculate and display the mean value of five consecutive samples
Time per sample = 68ms + 32ms
Time per sample = 100ms
The sampling frequency is given by the inverse of the time per sample, so we have:
Sampling frequency = 1/Time per sample
Sampling frequency = 1/0.1s
Sampling frequency = 10kHz
Therefore, the maximum sampling frequency that the MicroBit can perform is 10kHz.

Using the Backward Chaining method, we will demonstrate that KB implies a. This question is related to artificial intelligence and requires the following terms: Backward Chaining method, KB, entails, diagram,
KB = {(p^q) ⇒r, (r^s) ⇒t, (r^x) ⇒g ,p,q, s};
a = t
To determine whether KB entails a, we'll use the backward chaining approach. We begin by considering a and applying the rule to the first clause in the KB, which specifies (r^s) ⇒t. Because t is true, r and s must both be true. Since r is true, p and q must both be true. Therefore, a is true
.KB = {a, ß, (anß) ⇒y, (and) ⇒y, (B^y) ⇒ 0, (y^0) ⇒ 8, 8⇒ µ};
We begin with α = µ and use the rule to identify the premises that must be true for α to be true.
According to (8⇒ µ), 8 must be true. S
ince 8 is true, (y^0) ⇒ 8 must also be true, which implies that y is false.
As a result, (B^y) ⇒ 0 must be correct because B is true. Similarly,
(and) ⇒y must be correct since y is false and both a and ß are true.
Finally, (anß) ⇒y must be correct since y is false and both a and ß are true. As a result, α is correct because all the premises are correct. Drawing the relevant diagram for each problem is the next step, which will be provided in the following solution.

While seamlessly autonomous weapons systems can be a source of alarm, a key challenge might well be their possible failure. Some claim that autonomous weapons can never be fully liable and dependable, and that a level of doubt will always remain. For this task, investigate the above subject by answering the following questions: a. What types of autonomous weapons might be developed within 10 years from now? b. What are the possible deployments of autonomous weapons? c. How likely is the development of relatively cheap autonomous weapons that are approachable and destructive in the hands of civilians? d. What sorts of regulatory actions might be required to head off this kind of possibility, and when would such actions be suitable?
While seamlessly autonomous weapons systems can be a source of alarm, a key challenge might well be their possible failure.
The United States, China, Russia, Israel, the United Kingdom, and South Korea are among the countries developing these systems. The following are some of the various autonomous weapons that may be developed within 10 years.
The development of autonomous weapons is ongoing, and there is no limit to the types that can be created. Nevertheless, there are several categories of autonomous weapons that might be developed within ten years:
- Lethal autonomous weapons: Lethal autonomous weapons are robotic systems that can detect, choose, and destroy targets without human intervention.
- Autonomous cyber weapons: Autonomous cyber weapons can be programmed to automatically discover, scan, and exploit systems on their own, without human intervention.
- Non-lethal autonomous weapons: Non-lethal autonomous weapons are self-governing systems that can control crowds, conduct surveillance, and perform other tasks without human intervention.
Autonomous weapons can be deployed in a variety of settings, including military, law enforcement, and private security. Military deployments are the most common, with unmanned aerial vehicles and unmanned ground vehicles being the most prevalent types. In law enforcement, autonomous weapons can be used to control crowds, monitor public spaces, and conduct surveillance. Private security companies can also use autonomous weapons to patrol private property and respond to security threats.
While it is possible that relatively cheap autonomous weapons will be developed in the future, it is unlikely that they will be widely available to civilians. Governments will probably control the development and distribution of autonomous weapons, ensuring that they remain in the hands of authorized personnel. However, it is still a concern because of the ease with which they can be accessed and utilized, causing damage and disruption in the hands of criminals and terrorists.
To prevent the misuse of autonomous weapons, regulatory action is required. The following are some of the potential regulations that could be put in place:
- Licensing requirements: Autonomous weapons could be subject to licensing requirements that limit their distribution to authorized personnel only.
- Technical safeguards: Autonomous weapons could be designed with technical safeguards to prevent unauthorized access and usage.
- Criminal penalties: Criminal penalties could be introduced for individuals who misuse autonomous weapons.
- International agreements: International agreements could be established to regulate the development and use of autonomous weapons. Such regulations would be suitable now before the weapons are put into use.
Autonomous weapons systems can be a source of alarm due to the level of uncertainty associated with their operation and failure. The autonomous weapon is a type of self-governing machine that can select and engage targets without human intervention. To prevent the misuse of autonomous weapons, regulatory action is required. Licensing requirements, technical safeguards, criminal penalties, and international agreements are potential regulations that could be put in place. Such regulations would be suitable now before the weapons are put into use.
