Explanation:

One of the basic notions of the software development process is SDLC models which stands for Software Development Life Cycle models. SDLC – is a continuous process, which starts from the moment, when it’s made a decision to launch the project, and it ends at the moment of its full remove from the exploitation. There is no one single SDLC model. They are divided into main groups, each with its features and weaknesses. The most used, popular and important SDLC models are given below:

1. Waterfall model

2. Iterative model

3. Spiral model

4. V-shaped model

5. Agile model

Stage 1. Planning and requirement analysis

Each software development life cycle model starts with the analysis, in which the stakeholders of the process discuss the requirements for the final product.

Stage 2. Designing project architecture

At the second phase of the software development life cycle, the developers are actually designing the architecture. All the different technical questions that may appear on this stage are discussed by all the stakeholders, including the customer.  

Stage 3. Development and programming

After the requirements approved, the process goes to the next stage – actual development. Programmers start here with the source code writing while keeping in mind previously defined requirements. The programming by itself assumes four stages

• Algorithm development

• Source code writing

• Compilation

• Testing and debugging

Stage 4. Testing

The testing phase includes the debugging process. All the code flaws missed during the development are detected here, documented, and passed back to the developers to fix.  

Stage 5. Deployment

When the program is finalized and has no critical issues – it is time to launch it for the end users.  

SDLC MODELS

Waterfall – is a cascade SDLC model, in which development process looks like the flow, moving step by step through the phases of analysis, projecting, realization, testing, implementation, and support. This SDLC model includes gradual execution of every stage completely. This process is strictly documented and predefined with features expected to every phase of this software development life cycle model.

ADVANTAGES  

Simple to use and understand

DISADVANTAGES

The software is ready only after the last stage is over

ADVANTAGES

Management simplicity thanks to its rigidity: every phase has a defined result and process review

DISADVANTAGES

High risks and uncertainty

Iterative SDLC Model

The Iterative SDLC model does not need the full list of requirements before the project starts. The development process may start with the requirements to the functional part, which can be expanded later.  

ADVANTAGES                                        

Some functions can be quickly be developed at the beginning of the development lifecycle

DISADVANTAGES

Iterative model requires more resources than the waterfall model

The paralleled development can be applied Constant management is required

Spiral SDLC Model

Spiral model – is SDLC model, which combines architecture and prototyping by stages. It is a combination of the Iterative and Waterfall SDLC models with the significant accent on the risk analysis.

Explanation:

The main reason why is because regular users don't have permission to write to /etc. Assuming this is Linux, it is a multi-user operating system. Meaning if there are user-application configuration files within /etc, it would prevent users from being able to customize their applications.

Answer:

It reduces the cost of multiple subscription, but the cost of management is applied.

Explanation:

Cloud computing is the use of online resources like storage infrastructure available on database servers to hold company resources on a central level. There are various platforms available in adopting cloud services and they are SaaS or software as a service, PaaS, or platform as a service, IaaS or infrastructure as a service etc.

SaaS is a cloud computing services where software applications are made centrally available for an organisation. It reduces the cost of purchasing multiple activation keys for software traditionally installed. But it requires a skilled personnel and annual or monthly subscription, which when added together, might spike the cost of deployment.

Final answer:

To replace the original main program with a function, define the function mph_and_minutes_to_miles() that prompts the user to enter miles per hour and minutes traveled, calculates the miles traveled, and displays the result.

Explanation:

To replace the original main program with the function mph_and_minutes_to_miles(), you can define the function as follows:

Then, you can simply call the mph_and_minutes_to_miles() function in your main program:

This will prompt the user to enter the miles per hour and minutes traveled, and then calculate and display the miles traveled.

Final answer:

To simplify the main program, define a function called mph_and_minutes_to_miles() that takes two inputs: miles_per_hour and minutes_traveled. Inside the function, calculate the hours_traveled by dividing minutes_traveled by 60.0. Then, calculate the miles_traveled by multiplying hours_traveled by miles_per_hour. Finally, print the result using the format() function.

Explanation:

To simplify the main program, you can define a function called mph_and_minutes_to_miles() that takes two inputs: miles_per_hour and minutes_traveled. Inside the function, you can calculate the hours_traveled by dividing minutes_traveled by 60.0. Then, you can calculate the miles_traveled by multiplying hours_traveled by miles_per_hour. Finally, you can print the result using the format() function to display the miles_traveled.

Here's an example of the function:

If you run the above code and enter the values 70.0 and 100.0 when prompted, it will output: Miles: 116.6666667

Answer:

widgets=float(input("Enter number of widgets you want to buy"))

if widgets<0:

print("Can't compute negative number")

else:

if widgets<100:

cost=widgets*25

else:

cost=widgets*20

print("The total cost of widgets is", cost,"cents")

Explanation:

First I made a variable called widgets to take input of the number of widgets the customer wants to buy. I use the first comditional statement to test if the number of items typed in is not less than zero.

The else statement computed the prices of widgets based on number of widgets greater than zero.

Another conditional statement to check if the widgets is lower that 100 or greater. The cost represents the total amount, in terms of cost it will take for some nuber of widgets.

The last line prints the total cost and some statments

Final answer:

A Python program to calculate the total cost of widgets takes the number of widgets as input, determines the price per widget based on order quantity, and calculates the total cost.

Explanation:

Python Program for Calculating Total Cost of Widgets

If a store sells widgets at 25 cents each for small orders or 20 cents each for orders of 100 or more, the following Python program will calculate the total cost based on the number of widgets ordered:

# Ask the user for the number of widgets ordered
number_of_widgets = int(input("Enter the number of widgets you want to order: "))
# Determine the price per widget based on the quantity
if number_of_widgets < 100:
   price_per_widget = 0.25
else:
   price_per_widget = 0.20
# Calculate the total cost
total_cost = number_of_widgets * price_per_widget
# Display the total cost
print(f"The total cost for {number_of_widgets} widgets at ${price_per_widget:.2f} each is: ${total_cost:.2f}")

This program first asks the user to enter the quantity of widgets they wish to order. It then uses a conditional statement to determine the price per widget based on the quantity. Finally, it calculates the total cost and prints the result.

Answer:

The lossy compression method is also known as irreversible compression and is beneficial if the quality of the data is not your priority. It slightly degrades the quality of the file or data but is convenient when one wants to send or store the data. This type of data compression is used for organic data like audio signals and images. The algorithm use in Lossy compression include: Transform coding, DCT, DWT, fractal compression, RSSMS.

The Lossless compression method is also known as reversible compression and is capable of reconstituting the original form of the data. The quality of the data is not compromised. This technique allows a file to restore its original form. Lossless compression can be applied to any file format can improve the performance of the compression ratio. The algorithm use in Lossless compression include: RLW, LZW, Arithmetic encoding, Huffman encoding, Shannon Fano coding.

Advantage of Lossy compression: Lossy compression can achieve a high level of data compression when compared to lossless compression.

Advantage of Lossless compression: Lossless compression doesn’t degrade the quality of data during compression

Disadvantage of Lossy compression: Lossy compression degrades the quality of the data during compression

Disadvantage of Lossless compression: Lossless compression has less data holding capacity when compared to lossy method

Example of type of data for Lossless compression: Text

Example of type of data for Lossy compression: Audio

Explanation:

Answer:

Lossless retains the file size while lossy algorithm discards excess files size or parts.

Explanation:

Compression algorithms are algorithms used to minimise the file size of a large file format. It is handy for maximising available disk space and reduce upload and download time of these files. Lossless and lossy are two types of compression algorithms.

Lossless algorithm is used to compress a file, but yet retains the structure of the original file or data. It is used where an identical file from the original is favourable and is used in archives.

Lossy is the opposite of lossless because it discards excess parts of a file. It is used in compressing audio files like MP3.

Final answer:

To calculate the cost of shipping a package based on weight, you can use the formula: 'shipCostCents' = FLAT_FEE_CENTS + (CENTS_PER_POUND * shipWeightPounds).

Explanation:

To calculate the cost of shipping a package that weighs 'shipWeightPounds', we can use the formula:
'shipCostCents' = FLAT_FEE_CENTS + (CENTS_PER_POUND * shipWeightPounds)

For example, if the flat fee is 75 cents and the weight of the package is 5 pounds, the calculation would be:
shipCostCents = 75 + (25 * 5) = 75 + 125 = 200 cents.

Final answer:

The problem involves calculating the shipping cost using a constant price per pound plus a flat fee. It exemplifies the importance of understanding unit conversions and shipping rate calculations for mailing packages.

Explanation:

The given problem requires creating a simple program that calculates the shipping cost based on the weight of a package. To begin the process:

Applying this to a real-world scenario helps understand why it matters. According to the information provided, understanding how to calculate shipping costs based on weight is essential for sending mail. For instance, if you had a package weighing 2 pounds, you would convert the weight to ounces (since there are 16 ounces in a pound), resulting in 32 ounces. Using the shipping rates mentioned (where the first 3 ounces cost $1.95, and each additional ounce costs $0.17), the cost for a 32-ounce package would be calculated as shown by LibreTexts™.

Answer:

A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.

Explanation:

We can calculate the channel capacity using Shannon's Capacity formula:

C = B + log₂ (1 + SNR)

Where C = Channel Capacity

           B = Bandwidth of the Channel

           SNR = Signal to Noise Ratio

We are given SNR in dB so we need to convert it into a ratio.

[tex]SNR_{dB}[/tex] = 10log₁₀ (SNR)

10 = 10log₁₀ (SNR)

1 = log₁₀ (SNR)

SNR = 10¹

SNR = 10

So, using Shannon Channel Capacity formula:

C = 10 x 10⁶ log₂ (1 + 10)

C = 34.5 MHz

Total amount of time required to transmit a 1MB file:

1MB = 1 x 8 Mbytes = 8Mb

C = 34.5 MHz = 34.5 Mb/s

Time required = 8Mb/34.5Mb/s = 0.23 seconds

A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.

To calculate the number of hours since a birthdate, multiply the number of days by 24 and insert the result in cell C15.

Explanation:

To calculate the number of hours since the birthdate, you need to first determine the number of days that have passed since that date. Once you have the number of days in cell C14, you multiply it by 24 to convert the number of days to a number of hours. For example, if cell C14 contains 10 days, then you would calculate the hours as follows:

You would then insert the result, 240 hours, into cell C15 to complete the calculation.

The number of hours since the birthdate is calculated by multiplying the number of days in cell C14 by 24.

To determine the duration in hours since the birthdate, the process involves converting the number of days provided in cell C14 into hours. As there are 24 hours in a day, multiplying the number of days by 24 yields the total number of hours.

This formulaic approach accounts for the full span of days indicated, translating it accurately into an hourly representation.

Act on converting different time units to facilitate precise calculations for varied temporal requirements. Understanding these conversions aids in transforming durations to the most fitting unit, catering to specific contexts and calculations.

void Shape :: member ( Shape s1, Shape s2 ) ; // pass by value

void Shape :: member ( Shape *s1, Shape *s2 ) ; // pass by pointer

void Shape :: member ( Shape& s1, Shape& s2 ) const ; // pass by reference

void Shape :: member ( const Shape& s1, const Shape& s2 ) ; // pass by const reference

void Shape :: member ( const Shape& s1, const Shape& s2 ) const ; // plus the function is const

Explanation:

void Shape :: member ( Shape s1, Shape s2 ) ; // pass by value

The s1 and s2 objects are passed by value as there is no * or & sign with them. If any change is made to s1 or s2 object, there will not be any change to the original object.

void Shape :: member ( Shape *s1, Shape *s2 ) ; // pass by pointer

The s1 and s2 objects are passed by pointer as there is a * sign and not & sign with them. If any change is made to s1 or s2 object, there will be a change to the original object.

void Shape :: member ( Shape& s1, Shape& s2 ) const ; // pass by reference

The s1 and s2 objects are passed by reference  as there is a & sign and not * sign with them. If any change is made to s1 or s2 object.

void Shape :: member ( const Shape& s1, const Shape& s2 ) ; // pass by const reference

The s1 and s2 objects are passed by reference  as there is a & sign and not * sign with them. The major change is the usage of const keyword here. Const keyword restricts us so we cannot make any change to s1 or s2 object.

void Shape :: member ( const Shape& s1, const Shape& s2 ) const ; // plus the function is const

The s1 and s2 objects are passed by reference  as there is a & sign and not * sign with them. const keyword restricts us so we cannot make any change to s1 or s2 object as well as the Shape function itself.
