解説
問 81
Incorrectア
The CGI in a is a mechanism by which a Web server calls an external program to generate pages dynamically, and has nothing to do with storing data on a user's PC. The CSS in b is a language that specifies the appearance (style) of a Web page, not a metadata format for conveying update information. Both a and b are wrong.
Incorrectイ
The RSS in b is correct, but the CGI in a is wrong. CGI is a mechanism for generating dynamic content and does not play the role of cookie, which temporarily stores data on a user's PC to identify the user.
Incorrectウ
The cookie in a is correct, but the CSS in b is wrong. CSS is a mechanism responsible for page styling (appearance), not a format that structures metadata such as headlines and summaries to distribute update information. The one that fits that purpose is RSS.
- エ
正解 Blank a is the mechanism that temporarily stores data on a user's PC through the Web browser and makes it possible to identify the user, so cookie goes in. Blank b is the format that describes metadata such as a Web site's headlines and summaries in a structured way and is used to notify users of update information, so RSS goes in. Therefore the correct combination is a: cookie / b: RSS, which is choice エ.
ここがポイント
- A cookie is a mechanism by which a Web site provider temporarily stores data on a user's PC through the browser, and it is used to identify users (for example, session management).
- RSS is a format that describes metadata such as a Web site's headlines and summaries in a structured way, and it can distribute a site's update information to users. CGI generates dynamic pages and CSS handles page styling; each has a different role.
