解説
問 64
Incorrectア
A standard for defining the unified design and layout of web pages describes CSS (Cascading Style Sheets), which has nothing to do with RSS. RSS is a format for distributing update information and does not define appearance.
- イ
正解 RSS (RDF Site Summary / Really Simple Syndication) is an XML-based format for distributing update information about web pages such as news sites and blogs. It describes meta-information like an article's headline, link (URL), summary, and update time in a structured way, so that an RSS reader (feed reader) can automatically gather and fetch and display updates from multiple sites at once. Choice イ, “A format for describing the headlines, links, summaries, and so on of web pages,” corresponds exactly to this definition, so it is the correct answer.
Incorrectウ
A service that registers bookmarks on a network and shares them with other users describes social bookmarking (an online bookmark-sharing service). RSS is not a bookmark-sharing service but a format for describing and distributing update information.
Incorrectエ
A protocol for encrypting data to send and receive it securely between a browser and a web server describes HTTPS (SSL/TLS). RSS is not a mechanism for encrypting communication but a format for describing content update information.
ここがポイント
- RSS is an XML-based format for describing and distributing update information such as the headlines, links, and summaries of websites (news, blogs, etc.); using an RSS reader, you can efficiently keep track of updates across multiple sites.
- Distinguishing it from similar concepts: defining design is CSS, encrypting communication is HTTPS (SSL/TLS), and sharing bookmarks is social bookmarking—all three differ from RSS.
