IPA IP 2022 Question 89
A question IPA Japan published in 令和4年度 ITパスポート試験 公開問題 問89, translated into English. ITPEC is based on the same exams.
Which of the following is an appropriate description concerning the text format and the HTML format that are used for outgoing messages and are specified when an e-mail is created?
Explanation
Hyperlinks on any text need HTML format — a text-format e-mail can only show the bare characters.
A text-format (plain-text) e-mail contains characters only. An HTML-format e-mail is written in HTML, so it can set links on chosen words, change font colour and size, and embed images; for the same reason it can also carry scripts, which is why HTML mail is a security risk and many mail clients block its scripts. Attachments are a separate part of the message (MIME) and work in either format.
Answer (c)
Why not others:
- •(a) — the reverse: scripts can be embedded in HTML mail; plain text has nothing that can run
- •(b) — files can be attached to a text-format e-mail too, since attachments do not depend on the body format
- •(d) — the reverse: colour and size are formatting, which only HTML format can express
Key rule: HTML mail can carry formatting, links and scripts; plain-text mail carries only characters, and attachments work with both.
