解説
問 31
Incorrectア
ASP stands for Application Service Provider, a business that provides the functions of business application software as a service over a network. What it provides is software functionality, not a line for connecting to the Internet, so it is incorrect.
- イ
正解 The correct answer is choice イ, ISP. ISP stands for Internet Service Provider, and it refers to a business that provides a “service for connecting to a communication network” that links a user's devices or corporate network to the Internet. This is exactly the definition of the “provider that offers a communication network for connecting to the Internet” that the question asks about, so it is correct.
Incorrectウ
SaaS stands for Software as a Service, a delivery model in which software is made available for use as a service over the Internet. It is a way of using software, not something that provides a communication network for connection, so it is incorrect.
Incorrectエ
SNS stands for Social Networking Service, a membership-based social service that supports interaction and connections between people. It is not a business that provides network connectivity, so it is incorrect.
ここがポイント
- An ISP is a business that provides Internet connection services. It stands between the user and the line carrier, playing the role of providing the means to connect to the Internet.
- ASP and SaaS are models that provide software functions over the network, and SNS is a social service; all of them differ in role from “providing the connection itself,” a distinction that should be kept clear.
