A linked List is more efficient in terms of memory usage if a list has 180 integers. an array is more efficient than a linked list for a list that has 20 integers. An array and a linked list will require the same amount of memory if the list has 1 element.

(a) Linked List is more efficient in terms of memory usage if a list has 180 integers in it since an array of type int is defined to hold up to 200 ints. An array of size 200 x 4 bytes will consume 800 bytes of memory, whether we use all of the memory or not. While the linked list, which can use memory on a per-node basis, will consume just the right amount of memory that is required for the given number of nodes. Therefore, it will be more effective.

(b) In terms of memory use, an array is more efficient than a linked list for a list that has 20 integers. 20 x 4 bytes = 80 bytes are required for storing an array of 20 integers, whereas an array of 20 integers in the linked list will require 20 nodes x 8 bytes per node = 160 bytes, which is double the amount of memory required for an array.

(c) An array and a linked list will require the same amount of memory if the list has 1 element. A linked list with only one node will require 8 bytes of memory (4 bytes for data, 4 bytes for next reference), while an array with 1 integer element will require 4 bytes of memory.

Answer:

Your professor may be looking for something simple. I am not sure the caliber your professor is expecting. But for a basic. You could make a simple loop to improve the code.

function start() {

 for (var i = 0; i < 9; i++) {

   move();

 }

}

With less text, this code will do the same task as the original program. We can prevent repeatedly repeating the same code by utilizing a loop.

From there you could make the moves dynamic...

function start(numMoves) {

 for (var i = 0; i < numMoves; i++) {

   move();

 }

}

This passes the number of mes as an argument..the code will move forward a specified number of times based on the value of the numMoves parameter.

Then from there we could add error handling to have it catch and handle any errors that may occur. This of course is if the move() function displays an error.

function start(numMoves) {

 try {

   for (var i = 0; i < numMoves; i++) {

     move();

   }

 } catch (e) {

   console.error(e);

 }

}

BONUS

Here is a combined executable code...explanation below...

// Define the move function

function move() {

 console.log("Moving forward");

}

// Define the start function

function start(numMoves) {

 try {

   for (var i = 0; i < numMoves; i++) {

     move();

   }

 } catch (e) {

   console.error(e);

 }

}

// Call the start function with 9 as an argument

start(9);

Explanation for bonus:

The move() and start() functions are defined in the code.

A message indicating that the object is moving forward is logged to the console by the straightforward move() function. The start() function calls this function.

Start() only accepts one argument, numMoves, which defines how many times to advance the object. To deal with any errors that might arise when calling the move() method, the function employs a try...catch block.

Based on the value of numMoves, the move() method is called a given number of times using the for loop.

Lastly, the object is advanced nine times by calling the start() procedure with the value 9.

This code requires that the move() function is defined someplace else in the code, or is provided by the environment where the code is being executed (such as a browser or Node.js).

When this code is executed, the start() function is invoked with the input 9 and the object is advanced nine times. Every time the loop executes, the move() function is invoked, which reports a message to the console indicating that the object is moving ahead. Any mistakes that can arise when invoking the move() function are caught and recorded to the console thanks to the try...catch block.

The bus transmits a memory address when primary storage is the sending or receiving device.

Bus in Computer Science- A bus is a collection of wires used to transmit data from one component to another on a motherboard or other electronic circuit board. In modern computer systems, buses have become a significant component.

The primary purpose of a bus is to enable the computer's different components to communicate with one another. Each bus in a computer has a fixed number of wires dedicated to transmitting data to specific parts of the computer. These buses' capacity and design are determined by the type of computer being built and the components being used. A computer may have a number of buses, each performing a specific function.

The transmission of memory addresses when primary storage is the sending or receiving device is made possible by a bus. To put it another way, the bus makes it possible for the computer's central processing unit (CPU) and random access memory (RAM) to communicate efficiently. When the CPU is looking for information, it sends a request to RAM, and the address of the data is transmitted over the bus. Then, once the requested data is found, it is sent back over the bus to the CPU, which can now use it to execute the instructions required for the computer to complete a given task.

In object-oriented design, objects may know how to communicate with one another across well-defined interfaces, but normally they are not allowed to know how other objects are implemented. This is known as information hiding.

Object-oriented design is the design of software in which the software is constructed by defining objects and their relationships. The objects are independent units that can be used across multiple programs, reducing development time and increasing code reuse.

It is crucial to keep the objects independent and autonomous, meaning that they should be able to interact with one another without knowing how other objects are implemented. The objects communicate through interfaces that define the methods and properties that can be used by other objects. This allows the objects to be modified and improved without affecting the rest of the system.

The concept of information hiding is important in object-oriented design because it ensures that objects are encapsulated and that the system is modular. This makes the software easier to maintain, extend, and modify. Information hiding is achieved by defining clear interfaces for objects that separate the public interface from the implementation details. By keeping the implementation details hidden, objects can be changed and improved without affecting the rest of the system.

The correct answer is TCP and UDP are two transport layer protocols that are used for sending data over a network. The following three statements correctly describe their functions:

The TCP source port number identifies the sending host on the network: TCP uses a 16-bit source port field to identify the sending process or application on the host. This helps the receiving host to identify the source of the data. UDP segments are encapsulated within IP packets for transport across the network: UDP does not have any built-in error recovery mechanism, so it simply encapsulates its segments within IP packets and sends them over the network. The source port field identifies the running application or service that will handle data returning to the PC establishing a session with the server: Both TCP and UDP use the source and destination port fields to identify the applications or services that will handle the data. The source port field helps the server to identify the process or application that sent the data and establish a session with the PC. In summary, TCP and UDP are transport layer protocols that use source and destination port numbers to identify the sending and receiving hosts and the applications or services that will handle the data. UDP simply encapsulates its segments within IP packets, while TCP establishes a reliable, connection-oriented session between the hosts.

The retransmission policy should be adopted to help reduce the increasing congestion caused by devices attempting to resend lost packets too quickly or too often.

A retransmission policy is a technique that requires the sending of packets until an acknowledgment is received from the receiver. When a packet is sent, it is kept in the queue until an acknowledgment is obtained. If no acknowledgment is obtained, the packet is considered lost and is retransmitted.

This cycle of sending and resending packets causes congestion in the network. As a result, the retransmission policy should be implemented to reduce congestion caused by devices that attempt to resend lost packets too frequently or too quickly.

The issue of too many packets present in the network at the same time, slowing data transmission and affecting the quality of service, is known as congestion. Congestion causes packet loss, slows data transmission, and lowers service quality, which affects the user experience. The following are some common sources of network congestion:

Packet loss occurs when one or more packets of data traveling through a network do not reach their intended destination. It may be caused by network congestion, poor network design, hardware failure, or packet corruption. When packet loss occurs, the data contained in the packet must be resent, resulting in increased network traffic, delays, and poor service quality.
