解説
問 63
- ア
正解 An intranet is a closed network built inside an organization (inside a company) by directly using technologies that matured on the internet, such as TCP/IP, HTTP, and web browsers. Therefore, choice ア, which states an internal organizational network built using internet technologies, is appropriate. It does not allow free access from outside the company, and its distinctive feature is that employees can share internal information and use business systems through the familiar mechanisms of the Web.
Incorrectイ
An intranet is a network closed within the organization; it is not something that anyone outside the company can freely connect to. On the contrary, it is premised on blocking unauthorized external access with firewalls and the like, so this description is exactly the opposite of the truth.
Incorrectウ
A network that connects multiple companies using internet technologies to conduct electronic commerce is the description of an extranet. Its scope differs from that of an intranet, which is closed within an organization.
Incorrectエ
An intranet is not defined by the transmission technology it uses (wired or wireless). It may include wireless LAN, and the condition of being composed of wired connections only has nothing to do with the essence of an intranet.
ここがポイント
- Intranet = a closed network built inside an organization using internet technologies (TCP/IP, the Web, etc.).
- Distinguish by scope: within an organization = intranet, between companies = extranet.
