10.1 Parents will register for the classes by sending an e-mail to the CAT teacher with the word 'SPREADSHEETS' or 'DATABASES' in the subject line - NSC Computer Application Technology - Question 10 - 2016 - Paper 2

There could be several reasons for the teacher not receiving the e-mails:

• The e-mails might have been identified as spam or placed in the junk mail folder due to the email filter settings.
• The e-mail address used may have been incorrect.
• The size of the attachment might be too large, causing it not to be delivered.
• There may not be sufficient storage in the inbox, preventing new messages from being received.

1. File type/extension: By searching for file types related to videos, such as .mp4, users can narrow down results to those that are likely to be the downloaded video.
2. Date range: Using the filter to search for files based on the date they were downloaded can help locate the video more efficiently.

Using the file type filter ensures that only relevant files are shown, reducing clutter and improving efficiency when searching. The date range filter can help in pinpointing the file more accurately by filtering out older downloads that are unlikely to be the video in question.

1. Use encryption: Ensuring that data is encrypted before being uploaded helps to protect sensitive information from unauthorized access.
2. Implement a secure connection: Utilizing a reliable VPN or secure connection protocols (such as HTTPS) during the transfer of data to the cloud can prevent interception.

1. Check the connection: Ensure that the device is properly connected to the internet and that there are no issues with the network.
2. Test the SSD: Attempt to swap it out with another SSD to see if it resolves any hardware-related issues or incompatibility that may be preventing access.

1. Update frequently: Regular updates keep your audience engaged and improve search engine rankings.
2. Interact with readers: Engaging with your audience through comments or feedback makes them feel valued and encourages ongoing participation.

An RSS feed is a tool that automatically updates users with the latest content from a website or blog without them having to visit the site directly. It saves time as it aggregates new posts and articles in one place, allowing users to receive updates at a glance.

1. Dependence on mobile device availability: If parents do not have a device to scan QR codes, they cannot access the information.
2. Potential security risks: QR codes can be misleading, directing users to untrustworthy sites which may compromise their security.

1. Check if the source spreadsheet was moved: If the graph was linked to an external source, confirm that the link still points to the correct file location.
2. Manually refresh the link: In the word processing document, refresh or update the link to ensure it retrieves the latest data from the spreadsheet.

The functions to be used are LEN to count the number of characters in the ID and IF to check if the length is equal to 13. So the formula for cell B2 would be: =IF(LEN(A2)=13, 'Y', 'N').

1. Flexibility: Telecommuting allows employees to create their own schedules, giving them the ability to balance personal and work responsibilities more effectively.
2. Reduced commutes: Employees save time and money by not having to travel to and from a physical workplace.

1. Video conferencing tools: Applications like Zoom or Google Meet allow employees to attend classes virtually and engage in real-time discussions.
2. Collaboration platforms: Tools like Microsoft Teams or Slack enable employees to participate in group discussions and share resources, maintaining communication with peers.
