how to identify the significant accounts, disclosures, and relevant assertions in auditing long-lived assets.
Answers
To identify the significant accounts, disclosures, and relevant assertions in auditing long-lived assets are as follows:
How do you calculate the Long-Lived assets?
Upon recognition, a long-lived asset is either reported under the cost model at its historical cost less accumulated depreciation (amortisation) and less any impairment or under the revaluation model at its fair value.
Why are long-lived assets are depreciated?
Long-term assets must be depreciated throughout the period of their useful lives, much like most other types of assets. It is because a long-term asset is not anticipated to produce benefits indefinitely.
The long-lived assets are also called Non-current assets, and they contain both tangible and intangible assets and are utilised throughout several operational cycles.
-Tangible assets are things with a physical shape. • Equipment, structures, and land.
-Intangible assets have a form that is not physical. • Copyrights, patents, trademarks, and brand recognition.
Hence, the significant accounts, closures and relevant assertions are identified by the above steps.

How does a computer go through technical stages when booting up and navigating to the sample website? Answer the question using Wireshark screenshots.
Answers
When a computer is turned on, it goes through several technical stages before it can navigate to a sample website. The following are the basic steps involved in booting up a computer and accessing a website:
How to explain the informationPower On Self Test (POST): When a computer is turned on, it undergoes a Power On Self Test (POST) process, which checks the hardware components such as RAM, hard drive, CPU, and other peripherals to ensure they are functioning properly.
Basic Input/Output System (BIOS) startup: Once the POST process is complete, the BIOS program stored in a chip on the motherboard is loaded. The BIOS program initializes the hardware components and prepares the system for booting.
Boot Loader: After the BIOS startup is complete, the boot loader program is loaded. This program is responsible for loading the operating system into the computer's memory.
Operating System (OS) startup: Once the boot loader program has loaded the operating system, the OS startup process begins. During this process, the OS initializes the hardware, loads device drivers, and starts system services.
Web browser launch: After the OS startup is complete, the user can launch a web browser. The web browser program is loaded into the memory, and the user can navigate to a sample website.
DNS Lookup: When the user types in the website address, the computer performs a Domain Name System (DNS) lookup to translate the website name into an IP address.
HTTP Request: After the IP address is obtained, the web browser sends an HTTP request to the web server that hosts the website.
Website content delivery: Once the web server receives the HTTP request, it sends back the website content to the web browser, and the website is displayed on the user's screen.

In Coral Code Language - A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given the caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 18 hours.
Ex: If the input is 100, the output is:
After 6 hours: 50.0 mg
After 12 hours: 25.0 mg
After 18 hours: 12.5 mg
Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg.
Answers
To calculate the caffeine level after 6, 12, and 18 hours using the half-life of 6 hours, you can use the formula:
Caffeine level = Initial caffeine amount * (0.5 ^ (time elapsed / half-life))
Here's the Coral Code to calculate the caffeine level:
function calculateCaffeineLevel(initialCaffeineAmount) {
const halfLife = 6; // Half-life of caffeine in hours
const levelAfter6Hours = initialCaffeineAmount * Math.pow(0.5, 6 / halfLife);
const levelAfter12Hours = initialCaffeineAmount * Math.pow(0.5, 12 / halfLife);
const levelAfter18Hours = initialCaffeineAmount * Math.pow(0.5, 18/ halfLife);
return {
'After 6 hours': levelAfter6Hours.toFixed(1),
'After 12 hours': levelAfter12Hours.toFixed(1),
'After 18 hours': levelAfter18Hours.toFixed(1)
};
}
// Example usage:
const initialCaffeineAmount = 100;
const caffeineLevels = calculateCaffeineLevel(initialCaffeineAmount);
console.log('After 6 hours:', caffeineLevels['After 6 hours'], 'mg');
console.log('After 12 hours:', caffeineLevels['After 12 hours'], 'mg');
console.log('After 18 hours:', caffeineLevels['After 18 hours'], 'mg');
When you run this code with an initial caffeine amount of 100 mg, it will output the caffeine levels after 6, 12, and 18 hours:
After 6 hours: 50.0 mg
After 12 hours: 25.0 mg
After 18 hours: 12.5 mg
You can replace the initialCaffeineAmount variable with any other value to calculate the caffeine levels for different initial amounts.

int main() { // start of main() function body
char personName[100]; //char type array that holds person name
char searchChar; //stores character to be searched in personName
char* searchResult = nullptr; // pointer. This statement is same as searchResult = NULL
cin.getline(personName, 100); //reads the input string i.e. person name
cin >> searchChar; // reads the value of searchChar which is the character to be searched in personName
/* Your solution goes here */
searchResult = strchr(personName, searchChar); //find the first occurrence of a searchChar in personName
if (searchResult != nullptr) //if searchResult is not equal to nullptr
{cout << "Character found." << endl;} //displays character found
else //if searchResult is equal to null
{cout << "Character not found." << endl;} // displays Character not found
return 0;}
For example the user enters the following string as personName
Albert Johnson
and user enters the searchChar as:
J
Then the strchr() searches the first occurrence of J in AlbertJohnson.
The above program gives the following output:
Character found.
As you know computer system stores all types of data as stream of binary digits (0 and 1). This also includes the numbers having fractional values, where placement of radix point is also incorporated along with the binary representation of the value. There are different approaches available in the literature to store the numbers having fractional part. One such method, called Floating-point notation is discussed in your week 03 lessons. The floating point representation need to incorporate three things:
• Sign
• Mantissa
• Exponent
A. Encode the (negative) decimal fraction -9/2 to binary using the 8-bit floating-
point notation.
B. Determine the smallest (lowest) negative value which can be
incorporated/represented using the 8-bit floating point notation.
C. Determine the largest (highest) positive value which can be
incorporated/represented using the 8- bit floating point notation.

Answer:
A. Encode the (negative) decimal fraction -9/2 to binary using the 8-bit floating-point notation.
First, let's convert -9/2 to a decimal number: -9/2 = -4.5
Now, let's encode -4.5 using the 8-bit floating-point notation. We'll use the following format for 8-bit floating-point representation:
1 bit for the sign (S), 3 bits for the exponent (E), and 4 bits for the mantissa (M): SEEE MMMM
Sign bit: Since the number is negative, the sign bit is 1: 1
Mantissa and exponent: Convert -4.5 into binary and normalize it:
-4.5 in binary is -100.1. Normalize it to get the mantissa and exponent: -1.001 * 2^2
Mantissa (M): 001 (ignoring the leading 1 and taking the next 4 bits)
Exponent (E): To store the exponent (2) in 3 bits with a bias of 3, add the bias to the exponent: 2 + 3 = 5. Now, convert 5 to binary: 101
Now, put the sign, exponent, and mantissa together: 1101 0010
So, the 8-bit floating-point representation of -9/2 (-4.5) is 1101 0010.
B. Determine the smallest (lowest) negative value which can be incorporated/represented using the 8-bit floating-point notation.
To get the smallest negative value, we'll set the sign bit to 1 (negative), use the smallest possible exponent (excluding subnormal numbers), and the smallest mantissa:
Sign bit: 1
Exponent: Smallest exponent is 001 (biased by 3, so the actual exponent is -2)
Mantissa: Smallest mantissa is 0000
The 8-bit representation is 1001 0000. Converting this to decimal:
-1 * 2^{-2} * 1.0000 which is -0.25.
The smallest (lowest) negative value that can be represented using the 8-bit floating-point notation is -0.25.
C. Determine the largest (highest) positive value which can be incorporated/represented using the 8-bit floating-point notation.
To get the largest positive value, we'll set the sign bit to 0 (positive), use the largest possible exponent (excluding infinity), and the largest mantissa:
Sign bit: 0
Exponent: Largest exponent is 110 (biased by 3, so the actual exponent is 3)
Mantissa: Largest mantissa is 1111
The 8-bit representation is 0110 1111. Converting this to decimal:
1 * 2^3 * 1.1111 which is approximately 1 * 8 * 1.9375 = 15.5.
The largest (highest) positive value that can be represented using the 8-bit floating-point notation is 15.5.
