In the given scenario, if we use "InputStream" class object that inputs value from the user-end, in which we use "readInt" keyword. In Java, this function of the DataInputStream class reads 4 input bytes and returns an integer value. This method takes the next 4 bits from the input stream, transforms them to integers, and would then returns.
And the wrong choice can be defined as follows:
For choice 1, it use the "readLine" method which inputs the string value.For choice 2, it use the "println" method which prints value.For choice 4, the "nextInt" method is the part of "Scanner" class.Therefore, the answer is "Option 3", which is "var applesToBuy - readInt("How many apples would you like?");".

The objective of this task is to use Scapy to estimate the distance, in terms of number of routers, between your VM and a selected destination. This is basically what is implemented by the traceroute tool. In this task, we will write our own tool. The idea is quite straightforward: just send an packet (any type) to the destination, with its Time-To-Live (TTL) field set to 1 first. This packet will be dropped by the first router, which will send us an ICMP error message, telling us that the time-to-live has exceeded. That is how we get the IP address of the first router. We then increase our TTL field to 2, send out another packet, and get the IP address of the second router. We will repeat this procedure until our packet finally reach the destination. It should be noted that this experiment only gets an estimated result, because in theory, not all these packets take the same route (but in practice, they may within a short period of time). The code in the following shows one round in the procedure. a = IP() a.dst = ’1.2.3.4’ a.ttl = 3 b = ICMP() send(a/b) If you are an experienced Python programmer, you can write your tool to perform the entire procedure automatically. If you are new to Python programming, you can do it by manually changing the TTL field in each round, and record the IP address based on your observation from Wireshark. Either way is acceptable, as long as you get the result.

Why do the optical signals used in optical fibre cables have a
very short wavelength?
Answer:
Optical signals have very high frequencies. A high frequency means a short wave length because the wave length is inversely proportional to the frequency (λ = v/f), where v is the propagation speed in the media.
Explanation:
Since optical signals have a greater frequency, measured in nanometers, their wavelengths are shorter (10-9 meter). A billionth of a meter is equal to one nanometer (nm), a unit of length.
What are optical signals?An electromagnetic signal is an optical signal. It has oppositely polarised magnetic and electric fields.
The frequency of this EM pulse is typically very high (in the order of THz). As a result, measuring it in terms of wavelength is more practical.
The frequency of optical communications are very high. Since the wave length and frequency are inversely related, a high frequency implies a short wavelength.
To a receiving end, where the light signal is processed as data, the fiber transfers "data" by light.
As a result, fiber optics serves as a "pipe" or transmission medium for signals that need to travel vast distances quickly.
Thus, the optical signals used in optical fiber cables have a very short wavelength.

In Reinforcement Learning, algorithms that learn from trial and error are called
Answer:
Explanation:Reinforcement Learning(RL) is a type of machine learning technique that enables an agent to learn in an interactive environment by trial and error using feedback from its own actions and experiences.
In Reinforcement Learning, algorithms that learn from trial and error are called as long term reward.
What are reinforcement learning?Reinforcement learning are defined as a branch of machine learning that looks at how intelligent agents should behave in a given situation to maximize the idea of cumulative reward. In order to optimize the "reward function" or other user-provided reinforcement signal that builds up from the immediate rewards, the agent uses reinforcement learning to develop an optimal or nearly optimal strategy.
Long term rewards are defined as a corporate policy that pays staff for achieving defined objectives that boost shareholder value. Without using a world model, learn how to plan out scenarios and behaviors to maximize long-term gain.
Thus, in Reinforcement Learning, algorithms that learn from trial and error are called as long term reward.

Write a Java program that asks the user to enter an array of integers in the main method. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap
Answer:
In Java:
import java.util.*;
class Main {
public static void minGap(int intArray[], int arrlength) {
if(arrlength <2){return;}
int minm = Math.abs(intArray[1] - intArray[0]);
for (int i = 2; i < arrlength; i++)
minm = Math.min(minm, Math.abs(intArray[i] - intArray[i - 1]));
System.out.print("Minimum Gap = " + minm);
}
public static void main(String arg[]) {
Scanner input = new Scanner(System.in);
int arrlength;
System.out.print("Array Length: ");
arrlength = input.nextInt();
int[] intArray = new int[arrlength];
for(int i = 0;i<arrlength;i++){
intArray[i] = input.nextInt();
}
minGap(intArray, arrlength);
} }
Explanation:
The minGap method begins here
public static void minGap(int intArray[], int arrlength) {
This checks if array length is 1 or 0. If yes, the program returns nothing
if(arrlength <2){return;}
If otherwise, this initializes the minimum gap to the difference between the 0 and 1 indexed array elements
int minm = Math.abs(intArray[1] - intArray[0]);
This iterates through the array elements
for (int i = 2; i < arrlength; i++)
This checks for the minimum gap
minm = Math.min(minm, Math.abs(intArray[i] - intArray[i - 1]));
At the end of the iteration, the minimum gap is printed
System.out.print("Minimum Gap = " + minm);
}
The main method begins here
public static void main(String arg[]) {
Scanner input = new Scanner(System.in);
This declares the length of the array
int arrlength;
This prompts the user for array length
System.out.print("Array Length: ");
This gets the user input
arrlength = input.nextInt();
This declares the array
int[] intArray = new int[arrlength];
The following iteration gets input for the array
for(int i = 0;i<arrlength;i++){
intArray[i] = input.nextInt();
}
This calls the minGap method
minGap(intArray, arrlength);
}
Our tests will run your program with input 2, then run again with input 5. Your program should work for any input, though.
Write code that outputs variable numDays. End with a newline
Answer:
In Python:
numDays = int(input("Days: "))
print("Number of days: "+str(numDays)+"\n")
Explanation:
The program was written in Python and the explanation is as follows;
First, get the input for the number of days from the user
numDays = int(input("Days: "))
Next, print string "Number of days: " followed by the number input from the user and then newline
print("Number of days: "+str(numDays)+"\n")
The character \n represents new line
The following code will not display the results expected by the programmer. Can you find the error? Declare Real lowest, highest, average Display "Enter the lowest score." Input lowest Display "Enter the highest score." Input highest Set average = low + high / 2 Display "The average is ", average, "."
Based on the information given, the first error in the code is that the Variable name is lowest, NOT low, and Set average = low + high / 2.
How to find the error in the code.For Error 2: Variable name is highest, NOT high and Set average = low + high / 2
For Error 3 : Set average = low + high / 2. Thus, you will need to add the lowest and highest, then perform the division by 2
Set average = (lowest + highest) / 2 is the the correct statement.

If there’s one topic that trips people up (both new and experienced) in the networking industry, it is that of Subnetting.
One of the reasons this happens is that one has to perform (mental) calculations in decimal and also binary. Another reason is that many people have not had enough practice with subnetting.
In this article, we will discuss what Subnetting is, why it came about, its usefulness, and how to do subnetting the proper way. To make this article as practical as possible, we will go through many examples.
Note: While subnetting applies to both IPv4 and IPv6, this article will only focus on IPv4. The same concepts explained here can be applied to IPv6. Moreover, subnetting in IPv6 is more of a want rather than a necessity because of the large address space.
IP address network
For example, any traffic with a destination IP address of 192.168.1.101 will be delivered to PC1, while traffic addressed to 192.168.1.250 will be delivered to SERVER.
Note: This is an oversimplification of things just for understanding sake and refers to Unicast (one-to-one) IPv4 addresses. Traffic sent to Multicast (one-to-many) and Broadcast (one-to-all) IP addresses can be delivered to multiple devices. Also, features like Network Address Translation (NAT) allow one IP address to be shared by multiple devices.
To help your understanding of IP addresses and subnetting, you need to resolve the following fact in your head: Computers think in binary, that is, 0s and 1s. Therefore, even though we see an IP address represented like 192.168.1.250, it is actually just a string of bits – 32 bits in total for IPv4 addresses.
To make them more readable for humans, IPv4 addresses are represented in dotted decimal notation where the 32 bits are divided into 4 blocks of 8 bits (also known as an octet), and each block is converted to a decimal number.
For example, 01110100 in binary is 116 in decimal:
A unicast IPv4 address such as 192.168.1.250 can be divided into two parts: Network portion and Host ID. So what does this mean? Well, IPv4 addresses were originally designed based on classes: Class A to Class E. Multicast addresses are assigned from the Class D range while Class E is reserved for experimental use, leaving us with Class A to C:
Class A: Uses the first 8 bits for the Network portion leaving 24 bits for host IDs. The leftmost bit is set to “0”.
Class B: Uses the first 16 bits for the Network portion leaving 16 bits for host IDs. The two leftmost bits are set to “10”.
Class C: Uses the first 24 bits for the Network portion leaving 8 bits for host IDs. The three leftmost bits are set to “110”.
Note: The range of Class A is actually 1-126 because 0.x.x.x and 127.x.x.x are reserved.
With these classes, a computer/device can look at the first three bits of any IP address and determine what class it belongs to. For example, the 192.168.1.250 IP address clearly falls into the Class C range.
Looking at the Host ID portion of the classes, we can determine how many hosts (or number of individual IP addresses) a network in each class will support. For example, a Class C network will ideally support up to 256 host IDs i.e. from 00000000 (decimal 0) to 11111111 (decimal 255). However, two of these addresses cannot be assigned to hosts because the first (all 0s) represents the network address while the last (all 1s) represents the broadcast address. This leaves us with 254 host IDs. A simple formula to calculate the number of hosts supported
Explanation: Final answer is Start address: 192.168.58.0 + 1 = 192.168.58.1
End address: 192.168.58.16 – 2 = 192.168.58.14
Broadcast address: 192.168.58.16 – 1 = 192.168.58.15

Suppose end system A wants to send a large file to end system B. At a very high level, describe how end system A creates packets from the file. When one of these packets arrives to a packet switch, what information in the packet does the switch use to determine the link onto which the packet is forwarded
Answer:
The answer is below
Explanation:
Suppose end system A wants to send a large file to end system B, the large file is first divided into smaller chunks. Each chunk is then assigned a header forming a packet. Multiple packets are being generated with each of the packet containing a unique destination address in its header.
When a packet arrives at the packet switch, the switch uses the unique destination address that is attached in the header of the packet to determine the link onto which the packet is to be forwarded.
