Unsolicited electronic messages sent for marketing purposes are called______.
- A.virus
- B.unzip
- C.spam
- D.URL
Correct answer
Explanation
The correct answer is C, spam. Unwanted bulk messages sent to many people to advertise something are called spam. Spam usually arrives as e-mail, but the same word is used for unwanted SMS, blog comments and social media messages. Mail services run spam filters that study the sender, the subject line and the words used, and move such mail to a separate Spam or Junk folder so that it never reaches the inbox. Spam that pretends to come from a bank and asks for passwords or card details is called phishing, and a person who sends spam is a spammer. Option A is wrong because a virus is a harmful program that copies itself into other files and damages data. Option B is wrong because unzip only means opening a compressed file such as a .zip archive. Option D is wrong because a URL is the address of a web page. Exam tip: unwanted bulk mail is spam, while fake mail that asks for your details is phishing.
