Worked Solution & Example Answer:5.1 Give TWO reasons why buffering occurs when streaming a video - NSC Computer Application Technology - Question 5 - 2024 - Paper 2
Step 1
Give TWO reasons why buffering occurs when streaming a video.
Answer
- Not enough bandwidth or high resolution video: Streaming high-resolution videos requires significant internet bandwidth. If the available bandwidth is insufficient, buffering occurs due to the inability to load the video smoothly.
- Bad or slow connection: A poor internet connection, either due to physical distance from the router or network congestion, can also lead to buffering as the data packets take too long to reach the device.
Step 2
Discuss TWO reasons why having a server in a school network is advisable.
Answer
- Sharing of hardware and software resources: A server allows multiple users in a school to share resources like printers and applications, reducing costs and improving accessibility for students and staff.
- Improved security and control over user access: Having a server in place enables better management of data and user permissions, ensuring that sensitive information is secure and that access is granted appropriately.
Step 3
Explain what a blog is.
Answer
A blog is a type of website or online platform that regularly features posts, articles, or entries presented in reverse chronological order, allowing for the most recent content to appear first. Blogs often reflect personal opinions or expertise and can cover a wide array of topics, enabling communication with an online audience.
Step 4
Give TWO advantages of podcasts.
Answer
- Accessibility: Podcasts allow users to access content anytime, whether during a commute, while doing chores, or at the gym, making information consumption flexible and convenient.
- Diverse topics: Podcasts cover a wide range of subjects, catering to various interests and demographics, giving audiences the opportunity to learn about different topics in depth.
Step 5
State TWO factors that will impact internet data usage.
Answer
- The type of activities performed online: Engaging in data-heavy tasks such as video streaming, gaming, or large downloads will significantly increase data usage compared to simple browsing or reading websites.
- Duration of internet usage: The longer a user is online, the more data is consumed, especially for activities that involve constant data transmission, like video calls or live streaming.
Step 6
Give TWO examples where grid computing can be used.
Answer
- Weather forecasting: Grid computing can process vast amounts of data collected from various sources to predict weather patterns more accurately.
- Scientific research: Complex calculations needed in fields such as genetics or cancer research can be distributed across multiple machines, significantly speeding up the analysis process.
Step 7
State TWO guidelines to follow when communicating with teachers on social media.
Answer
- Use clear language and proper sentence construction: Communication should be professional and easy to understand to ensure respect and clarity.
- Be polite and respectful: Maintaining a courteous tone is essential in all communications, regardless of the medium, to foster positive relationships.
Step 8
Give TWO possible reasons why the service provider blocks the specific e-mail.
Answer
- The attachment is marked as malicious: If the service provider’s filters detect potentially harmful content in the attachments, the email may be blocked to protect users.
