The report should include sections covering introduction, problems and proposed solutions, projectlysis. . Specific planning, feasibility study, requirements determination, and system analysis. Specifically, the project planning section should outline the System Development Life Cycle (SDLC), present a Gantt Chart, and provide a Workload Matrix. The feasibility study section should address operational, technical, economic, and schedule feasibility. Requirements determination should involve interviews and document review. System analysis should include design diagrams like ERD, context diagram, and Level-0 DFD.
The group assignment involves creating a comprehensive report for a selected system, focusing on various aspects of the development process. The introduction section should provide an overview of the chosen system and its importance. The problems and proposed solutions section should identify the challenges or issues faced by the current system and propose solutions to address them effectively.
The project planning section plays a crucial role in outlining the development process. It should include an explanation of the chosen SDLC methodology, a Gantt Chart to illustrate the project timeline and milestones, and a Workload Matrix to distribute tasks and responsibilities among group members.
The feasibility study section evaluates the feasibility of implementing the proposed system. Operational feasibility can be assessed using the PIECES framework, which stands for Performance, Information, Economy, Control, Efficiency, and Service. Technical feasibility examines the technological requirements and constraints. Economic feasibility considers the financial viability of the project. Schedule feasibility analyzes whether the project can be completed within the given time frame.
Requirements determination involves gathering requirements through interviews with stakeholders and reviewing relevant documents to understand the system's functionalities and user needs.
System analysis includes designing various diagrams to understand the system's structure and flow. This may involve creating an Entity-Relationship Diagram (ERD) to represent the database structure, a context diagram to visualize the system's boundaries and interactions with external entities, and a Level-0 Data Flow Diagram (DFD) to illustrate the overall flow of data and processes.
By following these guidelines, the group can create a comprehensive report that covers all the necessary aspects of system development, ensuring a structured and well-planned approach to the project.

To make the sprite move in the opposite direction, change the code that updates its position by using subtraction instead of addition.
We have,
To change the block input so that the sprite moves in the opposite direction, you can modify the code that controls the sprite's movement.
Specifically, you need to change the value of the variable that determines the direction of movement.
For example, if you have a block of code like this in a programming environment:
sprite.x += speed
To make the sprite move in the opposite direction, you can change it to:
sprite.x -= speed
This will reverse the direction of movement along the x-axis.
Similarly, you can apply the same concept to other axes or dimensions, depending on the specific movement you want to reverse.
Remember, the exact implementation might vary depending on the programming environment you're using, but the general idea is to modify the code that updates the sprite's position to change the direction of movement.
Thus,

9. List the three frequency bands mostly used in satellite communications and explain for each band, the followings:
a. Attenuation
b. Interference with terrestrial systems
c. Bandwidth
d. Antenna size
The three frequency bands commonly used in satellite communications are L-band, Ku-band, and Ka-band. Each band has different characteristics regarding attenuation, interference with terrestrial systems, bandwidth, and antenna size.
1. L-band:
- Attenuation: L-band signals experience moderate attenuation due to rain, foliage, and atmospheric conditions. They can penetrate buildings and provide reliable communication in adverse weather conditions.
- Interference with terrestrial systems: L-band signals have a lower probability of interference with terrestrial systems because they operate at lower frequencies and are less susceptible to interference from terrestrial transmitters.
- Bandwidth: L-band provides a relatively narrow bandwidth, typically around a few hundred megahertz, limiting the data transmission capacity.
- Antenna size: L-band systems require larger antennas compared to higher frequency bands due to the longer wavelength. This is necessary to achieve sufficient gain and link quality.
2. Ku-band:
- Attenuation: Ku-band signals experience higher attenuation compared to L-band, particularly in heavy rain conditions. This can lead to a degradation in signal quality.
- Interference with terrestrial systems: Ku-band signals can potentially experience interference from terrestrial systems, such as microwave links and wireless communication networks operating in similar frequency ranges.
- Bandwidth: Ku-band offers a wider bandwidth, typically several gigahertz, allowing for higher data transmission rates.
- Antenna size: Ku-band systems require smaller antennas compared to L-band due to the shorter wavelength. Smaller antennas are more manageable and cost-effective for satellite communication.
3. Ka-band:
- Attenuation: Ka-band signals experience higher attenuation due to rain, which can cause significant signal degradation during heavy rainfall.
- Interference with terrestrial systems: Ka-band signals have a higher potential for interference from terrestrial systems, including wireless networks, due to their increasing use for broadband communication.
- Bandwidth: Ka-band provides a wide bandwidth, typically multiple gigahertz, enabling high-speed data transmission and supporting bandwidth-intensive applications.
- Antenna size: Ka-band systems require even smaller antennas compared to Ku-band due to the shorter wavelength. This allows for compact and lightweight antenna designs, suitable for applications such as consumer broadband services.
In summary, the three frequency bands used in satellite communications, namely L-band, Ku-band, and Ka-band, exhibit different characteristics regarding attenuation, interference with terrestrial systems, bandwidth, and antenna size.
L-band offers moderate attenuation and interference resistance, with a relatively narrow bandwidth and larger antenna size. Ku-band experiences higher attenuation and potential interference, provides a wider bandwidth, and requires smaller antennas.
Ka-band faces higher attenuation and interference risks, offers a wide bandwidth, and requires even smaller antennas for effective communication.

Which is self incrementing looping statement
The self-incrementing looping statement in programming is usually called a for loop. A for loop allows you to execute a block of code repeatedly for a fixed number of times or until a certain condition is met.
What is the looping statement?In most programming languages, the for loop includes an index variable that is incremented or decremented automatically as the loop iterates. This is what makes it a self-incrementing looping statement.
For example, in Python, the following for loop counts from 0 to 4 and prints the value of the index variable at each iteration:
scss
for i in range(5):
print(i)
Therefore, In this example, i is the index variable, and range(5) specifies the range of values for i to take on. As the loop iterates, i will be automatically incremented by 1 at each iteration until it reaches the maximum value of 4.

What action(s) from the CRUD method should be used to describe the required data usage in the case of the function name is "Take delivery of a new goods" for the entity types: GOODS and DELIVERY?
The CREATE and UPDATE actions from the CRUD method should be used to describe the required data usage in the case of the function name "Take delivery of new goods" for the entity types GOODS and DELIVERY.
This is because CREATE is the action used for generating and inserting data into the database, whereas UPDATE is used for changing the existing data. A CRUD (Create, Read, Update, and Delete) is an acronym for database operations to enable the storage and management of data.
It is a standard and widely recognized method of performing database operations. The CREATE action involves adding a new item to the database, which is what happens when a new delivery of goods arrives. This operation stores new data in the database to allow the records to be retrieved when required. Similarly, the UPDATE operation allows the records in the database to be updated if new information becomes available or data errors occur. Therefore, the CREATE and UPDATE actions from the CRUD method should be used to describe the required data usage in the case of the function name "Take delivery of new goods" for the entity types GOODS and DELIVERY.
