Answers
The given key in the previous problem is an involutory key, which is true. What is the Involutory Key? The definition of an involutory key is as follows: If an encryption function is identical to the decryption function function, then the key k is said to be an involutory key.
So, if you use the same key to encrypt and decrypt the message, the key becomes an involutory key. In other words, suppose that the encryption function is E() and the decryption function is D(). Then, for any value of x, the following equation must hold true:
D (E (x)) = x Since the key used for encryption is the same as the key used for decryption, the equation can be expressed as: D (E (x, k)) = x, where k is the key used for both E() and D().
Therefore, the statement "The key given in the previous problem is an involutory key" is true as the key used in the previous problem has been identified as an involutory key.

FILL IN THE BLANK. one task of the ____ layer in a lan is to handle error detection using a crc.
Answers
One task of the data link layer in a lan is to handle error detection using a crc.
When data is transmitted between devices in a LAN, it is broken down into smaller frames at the data link layer. Each frame contains a header, data, and a trailer. The trailer includes a CRC, which is a mathematical calculation of the data in the frame.
When the receiving device receives the frame, it calculates its own CRC and compares it to the CRC in the trailer. If the two CRCs match, the data is assumed to be error-free and is passed up to the next layer. However, if the CRCs do not match, an error is assumed to have occurred during transmission and the frame is discarded.

Answers
Shoshana's rule allows TCP traffic from any source port within the IP address range 192.168.42.0/24 to reach destination port 443, enabling secure web Communication within her organization. Shoshana, as a network technician, is configuring firewall rules for her organization
Shoshana, as a network technician, is configuring firewall rules for her organization. The rule she has set is organized in the following order:
1. Protocol: The rule specifies the Transmission Control Protocol (TCP) as the communication protocol being used. This protocol ensures reliable and ordered delivery of data between devices.
2. Source Addresses: The rule defines the source IP addresses as 192.168.42.0/24. This notation represents an IP address range from 192.168.42.0 to 192.168.42.255, using a 24-bit subnet mask.
3. Source Ports: The rule allows for any source port to initiate communication. By using "any," Shoshana ensures that the source port number is not restricted, allowing traffic from a variety of applications.
4. Destination Ports: The rule specifies the destination port as 443. This is the default port for HTTPS traffic, ensuring secure web communication.
5. Action: Finally, the rule sets the action as "allow," permitting traffic that matches the specified protocol, source address range, source ports, and destination port to pass through the firewall.
In summary, Shoshana's rule allows TCP traffic from any source port within the IP address range 192.168.42.0/24 to reach destination port 443, enabling secure web communication within her organization.

Out of the given scheduling algorithms, option (a) First-come-first-served, (c) Priority, and (e) Shortest remaining time first may cause starvation. Therefore, the correct option is (a) a, c and e.What is starvation?
Starvation is a phenomenon where a process is prevented from receiving the resources it needs for a prolonged period due to the resource allocation algorithm's design. When a process is in a starving state, it waits indefinitely for the resources to be available, but the system can't provide them. The process is never allowed to proceed. Starvation can be defined as a situation in which a process is indefinitely postponed or delayed due to resource allocation errors. If there is insufficient memory space or insufficient CPU time to allocate to a process, starvation may occur.
Thus, starvation is a resource allocation issue. What are Scheduling Algorithms?A scheduler, also known as a dispatcher, is a mechanism used by an operating system (OS) to control how and when various processes are run. The scheduling algorithm decides which processes are given priority to the CPU based on various scheduling criteria.A scheduling algorithm is a procedure that selects a process from a ready queue and allocates the CPU to that process.
When a new process is generated or a previously blocked process becomes ready, the operating system uses a scheduling algorithm to select a process from the ready queue to be executed by the CPU. There are various scheduling algorithms used in operating systems to perform this process. These scheduling algorithms include:First-Come-First-Serve (FCFS)Shortest Job Next (SJN)Priority SchedulingRound Robin (RR)Shortest Remaining Time First (SRTF)The following is a list of the scheduling algorithms that can cause starvation:First-come-first-servedPriorityShortest remaining time first

remove the last element, then add a 2 to the end of the array.
Answers
Removing the last element and adding 2 to the end of an array can be done using various programming languages. However, regardless of the programming language, the basic procedure to remove the last element of an array is to identify the last element using its index and then delete it.
Here is how you can remove the last element and add 2 to the end of the array in Python using some example code: ``` python #creating an array arr = [1, 2, 3, 4, 5] #removing the last element del arr[-1] #adding 2 to the end of the array arr.append(2) #printing the updated array print(arr) ```The output of the above code will be: `[1, 2, 3, 4, 2]`This code first creates an array `arr` and initializes it with values 1, 2, 3, 4, and 5.
Then, the last element of the array is removed using the `del` statement and the `arr[-1]` expression. Finally, the number 2 is added to the end of the array using the `append()` method.

Answers
The statement "print moves to the beginning of the next line after displaying the string, but println does not advance to the next line when completed." is false.
The difference between print and println is that print moves to the beginning of the same line after displaying the string, while println moves to the beginning of the next line when completed. This means that if you use print multiple times, the output will be displayed on the same line, while if you use println multiple times, each output will be displayed on a new line. Here is an example: System.out.print("Hello"); System.out.print("World"); System.out.println("!"); // Output: HelloWorld!
