解説
問 57
Incorrectア
CSS (Cascading Style Sheets) is a language for specifying the appearance (style) of an HTML document, such as text color, layout, and fonts. It handles the decoration of a page and is not an information format for delivering a website’s update status, so it is incorrect.
Incorrectイ
DHCP (Dynamic Host Configuration Protocol) is a communication protocol that automatically assigns configuration information such as IP addresses to devices connecting to a network. It is a mechanism for IP address management and has nothing to do with a website’s update information, so it is incorrect.
Incorrectウ
ISMS (Information Security Management System) is a management framework that an organization continuously operates to protect its information assets. It is a management mechanism rather than an information format, and has nothing to do with keeping track of update status, so it is incorrect.
- エ
正解 RSS (Really Simple Syndication / RDF Site Summary) is a data format for delivering a website’s new articles and update information in a structured form. A site that supports RSS provides its updates as an RSS feed, and a user who subscribes to the feeds of multiple sites in an RSS reader (feed reader) can keep track of all the updates together without opening each site individually. Therefore, the information format used to keep track of a website’s update status is RSS, choice エ.
ここがポイント
- RSS is a data format for delivering a website’s new and updated information; with an RSS reader you can subscribe to and keep track of the updates of multiple sites in one place.
- Distinguish the roles of the abbreviations: CSS = appearance definition, DHCP = automatic IP address assignment, ISMS = information security management mechanism, RSS = a format for delivering update information.
