Your community has established a community policing forum (CPF) - NSC Computer Application Technology - Question 9 - 2017 - Paper 2

To troubleshoot the non-working mouse, I would take the following steps:

1. Check Physical Connections: Ensure that the mouse is properly plugged into the computer (check the cord for damage).

2. Test the Mouse: Use another mouse to see if the issue persists. This helps determine if the problem is with the mouse or the computer.

3. Battery Check (for Wireless Mouse): If it's a wireless mouse, check if the battery is flat and replace it if necessary.

4. Restart the Computer: Sometimes, simply restarting the computer may resolve the issue if it is software-related.

To enable wireless communication for the computers, the following two devices can be added:

1. Wi-Fi USB Adapter: This device allows the computer to connect to wireless networks without needing a built-in Wi-Fi card.

2. Wi-Fi Card: Installing a Wi-Fi card directly into the computer’s motherboard provides a more permanent solution for wireless connectivity.

Two indicators that suggest the computers are old include:

1. Slow Processing Speed: The Intel Dual Core 1.2 GHz processor is relatively outdated by current standards, leading to slow performance with modern applications.

2. Low RAM Capacity: The current system's RAM of only 1 GB is insufficient for running many contemporary applications, indicating that the hardware is behind current technology standards.

The CPF should consider purchasing high-capacity hard drives for several reasons:

1. Increased Storage Space: High-capacity HDDs can store a larger volume of video footage without the need for constant data management, making it easier to maintain surveillance records.

2. Longer Retention Periods: With greater storage, video footage can be retained for longer periods, which is essential for monitoring prolonged security situations and assisting in investigations.

One effective solution when the HDDs are full is to automatically delete the oldest recordings to free up space for new footage. This method ensures that surveillance continues without interruption while managing storage effectively.

Two disadvantages of using wireless cameras include:

1. Range Limitations: Wireless cameras may face connectivity issues if they are located too far from the network router, which can affect video quality and reliability.

2. Security Threats: Wireless cameras can be more susceptible to hacking or unauthorized access due to their reliance on radio frequencies for transmission.

Discussing victims of crime on social media may not be advisable for the following reasons:

1. Privacy Concerns: The privacy of crime victims should be respected to prevent further trauma or victimization.

2. Legal Implications: Public discussions may compromise ongoing legal processes and expose victims to potential backlash or judgment from the public.

Using WhatsApp for alerting residents to potential threats is beneficial because:

1. Instant Messaging: WhatsApp enables real-time communication, allowing timely alerts that can quickly inform residents of any immediate dangers.

2. Widespread Accessibility: Many residents are likely to have the app installed on their devices, making it a convenient platform for communication.

Text-to-speech software could be utilized to assist residents in accessing and understanding the contents of text messages. This software can convert written text into auditory information, making it easier for those with visual impairments or literacy challenges.

Backing up data to a cloud service is advisable for the following reasons:

1. Remote Access: Cloud services allow data access from any location with internet connectivity, ensuring convenience and flexibility in data retrieval.

2. Data Security: Cloud backups provide an additional layer of security, protecting vital information from local hardware failures or physical damage.

Two database features that can assist in determining the number of females older than 60 years include:

1. Queries: Custom queries can be written to filter records based on age and gender criteria.

2. Reports: Generating reports can help present the data in an organized format, making it easier to analyze the relevant demographic.

Using an input form provides a more user-friendly interface for data entry. It allows users to enter one record at a time, reducing errors and improving the accuracy of the data capture. Additionally, forms can be customized with validation rules, ensuring that the input data meets specific requirements.

To enhance the clarity of the graph, the following changes can be made:

1. Add a Title: Clearly label the graph to indicate what data is being represented.

2. Label Axes: Ensure both the x-axis and y-axis have appropriate labels that describe what is being measured.

3. Use Different Colors: Implement distinct colors for the different categories (e.g., burglaries vs. car thefts) to make it easier to differentiate between them.

A pie graph would not effectively represent this information because it is designed to show proportions of a whole for a single categorical variable. In this case, we have multiple categories (burglaries and car thefts) which are tracked over time, making a bar graph more appropriate to display trends and comparisons across different categories.
