問 56
- ア
正解 A function key refers to the “F1” through “F12” keys arranged along the top of the keyboard. Their defining feature is that, instead of entering a fixed character, they are assigned a specific function by each application or OS being used. For example, in many programs “F1” shows help, in Japanese input “F7” converts text to katakana, and in a browser “F5” reloads the page — so the same key behaves differently depending on the situation. This description, “a key to which a specific function is assigned for each application or OS”, correctly captures the essence of a function key, so ア is the correct answer.
Incorrectイ
“Something that displays the shape of a keyboard on the screen and realizes input processing through software” describes a software keyboard (on-screen keyboard), which is a different thing from a function key that is a physical key, so it is wrong.
Incorrectウ
“A conversion key for performing encryption and decryption” describes an encryption key (cryptographic key), a concept in the security field that has nothing to do with a function key, so it is wrong.
Incorrectエ
“Information for uniquely identifying a specific row” describes a database primary key, which is a different thing from a key on a keyboard, so it is wrong.
- A function key (F1–F12) is a special key that is assigned a specific function by each application or OS.
- The point being tested is distinguishing similar “key” terms (software keyboard, encryption key, primary key).
