解説
問 80
Incorrectア
Shareware is a classification of software by its distribution and payment model: it can be tried for free for a certain period, and payment is required to keep using it. It has nothing to do with whether the software is malicious, so it is not a general term for malicious software.
Incorrectイ
Firmware is basic software embedded in a device that directly controls the hardware, written into memory such as ROM. It is a legitimate control program, not a general term for malicious software.
- ウ
正解 The correct answer is choice ウ, Malware. Malware, short for malicious software, is a general term for illegitimate software created with the purpose of harming users or computers. The keylogger in the question (which secretly records keystrokes to steal information) and the worm (which self-replicates and spreads infection across networks) are both representative types included in malware. Computer viruses, Trojan horses, spyware, and ransomware are likewise classified as malware, and the general term that collectively refers to all of them is malware.
Incorrectエ
Middleware sits between the operating system and application software, providing common functions such as a database management system or a Web server. It has nothing to do with malice, and is also incorrect as a general term.
ここがポイント
- Malware is short for malicious software and is the general term for the entire body of harmful, illegitimate software such as viruses, worms, Trojan horses, spyware, keyloggers, and ransomware.
- Being able to distinguish the easily confused ware-suffix terms — shareware, firmware, and middleware — by their respective meanings (payment model / device control / intermediate software).
