his invention?

A.
Spam

B.
Patent

C.
Artistic license

D.
Phishing

Explanation:
A patent is a set of exclusive rights granted to anyone who invents any new and useful machine,
process, composition of matter, etc. A patent enables the inventor to legally enforce his right to
exclude others from using his invention.
Answer option C is incorrect. Artistic license ensures that the modifications to a software remain in
restrictive control of the Copyright Holder.
Under this licensing method, if the Copyright Holder does not like the direction of the changes, he
can stop the changes.
Answer option D is incorrect. Phishing is a type of scam that entice a user to disclose personal
information such as social security number, bank account details, or credit card number. An example
of phishing attack is a fraudulent e-mail that appears to come from a user’s bank asking to change
his online banking password. When the user clicks the link available on the e-mail, it directs him to a
phishing site which replicates the original bank site. The phishing site lures the user to provide his
personal information.
Answer option A is incorrect. Spam is a term that refers to the unsolicited e-mails sent to a large
number of e-mail users. The number of such e-mails is increasing day by day, as most companies
now prefer to use e-mails for promoting their products. Because of these unsolicited e-mails,
legitimate e-mails take a much longer time to deliver to their destination. The attachments sent
through spam may also contain viruses. However, spam can be stopped by implementing spam
filters on servers and e-mail clients.
