[&] What is a characteristic of Base64 encoding in terms of data conversion?
- It maps three bytes into four 6-bit units
- It converts two bytes into three 8-bit characters
- It splits four bytes into three 8-bit characters
- It defines a variable-length conversion for different data

[&] Why might Base64 not be suitable for data storage, despite its convenience for transmission?
- It requires specific software to decode
- It encrypts data which is hard to reverse
- It results in larger file sizes than original binary data
- It changes data, leading to corruption risks

[&] What is a common use case for Base64 encoding in web applications?
- To allow binary data in HTML or JSON
- To establish secure socket connections
- To replace CSS files with encoded scripts
- To format text data in JSON payloads

[&] Why might a web developer use Base64 encoding for images in an HTML file?
- To ensure images are visually clearer
- To embed images directly, minimizing HTTP requests
- To reduce the server's load by using smaller files
- To allow images to be editable directly on the web page

[&] What is the primary purpose of Base64 encoding?
- To eliminate the need for URLs in HTML
- To represent binary data in text formats
- To optimize image sizes for faster loading
- To encrypt data for secure transmission

[&] Which of the following character sets is used in Base64 encoding?
- Uppercase letters, lowercase letters, digits, and special symbols
- Uppercase letters, lowercase letters, spaces, and punctuation
- Uppercase letters, lowercase letters, digits, plus, and forward slash
- Uppercase letters, digits, and underscores
