This question's explanation and your answers so far.
問 74
Incorrectア
“A virtual private network constructed over the internet” describes a VPN (virtual private network), a technology that virtually turns a communication path into a dedicated line. It is a different thing from online storage, which is a data storage service, so it is incorrect.
- イ
正解 Online storage is a service that rents out disk space to users for storing data over the internet. Because you can keep files such as photos and documents on a server on the network rather than on your local device, you can access the same data from multiple devices and use it for backup or sharing. Choice イ describes exactly this definition, so it is the correct answer.
Incorrectウ
“Software that is distributed or sold over the internet” describes software delivered through online distribution or download sales. It describes a form of software distribution, not a service that rents out data storage space, so it is incorrect.
Incorrectエ
“A computer game that multiple people can join simultaneously over the internet” describes an online game. It is an entertainment service and has nothing to do with renting out storage (storage space), so it is incorrect.
- Online storage = a service for renting disk space for data storage on a server on the internet. It can be used for access from multiple devices, backup, and file sharing.
- Distinguishing confusing terms: VPN = virtual private network, online distribution/sale of software, and online games are each separate concepts; use the keyword “renting out space for storing data” to tell them apart.
