Email Fundamentals — What Types of Data Can Be Sent? In modern email systems, which kinds of files or media can you attach and send to another person?

Introduction / Context:
Understanding what email can transmit is a core digital skill. Although email was originally designed for text, it quickly evolved to support file attachments of many types, enabling users to share images, audio, video, and documents globally.

Given Data / Assumptions:

• Email clients and servers support attachments using MIME (Multipurpose Internet Mail Extensions).
• Receiving systems may enforce size limits (for example, 20–25 MB typical) but do not restrict attachment types to just one media category.
• Security filters may block risky file types, but standard media types are widely allowed.

Concept / Approach:
MIME encodes binary files for transport over text-based email protocols and labels them with content types (such as image/jpeg, audio/mpeg, video/mp4). Because the mechanism is generic, you can attach pictures, audio, videos, PDFs, spreadsheets, and more, subject to size and policy constraints. Therefore, the most accurate answer is that all of the listed media types can be sent via email.

Step-by-Step Solution:

Verification / Alternative check:
Open any mainstream email client (Gmail, Outlook, Apple Mail) and use “Attach file.” Supported file dialogs include images, audio, video, and documents.

Why Other Options Are Wrong:

• Audio, Pictures, Video individually are too narrow and ignore the broader capability.

Common Pitfalls:
Assuming email can only send text or small images. While very large videos may exceed limits, you can compress them or share links via cloud storage.

Final Answer:
All of the above
