ITPEC FE Subject A October 2025 Question 26
ITPEC FE Subject A October 2025 — Question 26 of 60
MIME (Multipurpose Internet Mail Extensions) — extends email headers to support multimedia content.
MIME allows email to carry not just plain text, but also audio, images, video, and other binary attachments by encoding them into text-safe formats.
How it works:
- Adds headers like Content-Type and Content-Transfer-Encoding
- Uses Base64 or quoted-printable encoding for binary data
- Defines multipart messages (e.g., multipart/mixed for attachments)
Why not others:
- (a) HTML — a markup language for web pages, not an email header standard
- (b) MHS — Message Handling System (X.400), an older messaging architecture
- (d) SMTP — the protocol for sending email, but only supports 7-bit ASCII text natively; MIME extends what SMTP can carry
Key point: SMTP delivers the mail, MIME defines what's inside it.
