Answer:
The field with a width of 8 bytes is the Number field.
Here is a detailed explanation:
Explanation:
- Each field in a database table has a specific data type and width that determines the amount of storage space it occupies.
- In this scenario, we are given four options: Memo, Number, Date/Time, and Hyperlink.
- We need to identify which of these fields has a width of 8 bytes.
Understanding the options:
1. Memo:
- Memo fields are used to store large amounts of text or data.
- The width of a Memo field can vary depending on the database system, but it is typically much larger than 8 bytes.
- Therefore, the Memo field is not the correct answer.
2. Number:
- Number fields are used to store numeric values such as integers or decimals.
- The width of a Number field can vary depending on the data type and precision specified.
- In this case, if the Number field has a data type of "Double", it will have a width of 8 bytes.
- Therefore, the Number field is the correct answer.
3. Date/Time:
- Date/Time fields are used to store date and time values.
- The width of a Date/Time field can vary depending on the data type and precision specified.
- However, it is unlikely that a Date/Time field would have a width of exactly 8 bytes.
- Therefore, the Date/Time field is not the correct answer.
4. Hyperlink:
- Hyperlink fields are used to store URLs or links to external resources.
- The width of a Hyperlink field can vary depending on the database system and the length of the URL.
- However, it is unlikely that a Hyperlink field would have a width of exactly 8 bytes.
- Therefore, the Hyperlink field is not the correct answer.
Conclusion:
- After analyzing the options, we can conclude that the field with a width of 8 bytes is the Number field.
- It is important to note that the width of a field can vary depending on the database system and the specific settings, so it is always recommended to refer to the documentation or specifications of the database being used for accurate information.
