解説
問 60
Incorrectア
Web mail (an e-mail service used in a browser) can switch formats and can send both HTML format and plain text format. Saying it “cannot send plain text format” is incorrect.
Incorrectイ
Attaching files such as images is handled by a mechanism separate from the body format (attachment via MIME), so image files can be attached even in plain text format. Limiting the ability to attach to HTML format is incorrect.
- ウ
正解 Plain-text-format e-mail is a bare format that sends only character information and cannot carry formatting such as font size or color. HTML format, in contrast, can be decorated with HTML tags just like a web page, and the character size, color, and other formatting specified by the sender are reflected in the display on the receiving side. Therefore choice “ウ”, which states that it is HTML format in which the sender can specify the formatting displayed on the receiving side, is appropriate.
Incorrectエ
A digital signature (such as S/MIME) can be applied to the entire e-mail, regardless of whether the body is in plain text format or HTML format. Saying you “cannot sign unless it is plain text format” is incorrect.
ここがポイント
- Plain text format has only characters, while in HTML format the sender can specify formatting such as character size, color, and typeface, which is reflected on the receiving side.
- File attachments such as images are handled by the MIME mechanism and do not depend on the body format, so they can be attached even in plain text format.
