Explanation:

Question 1

• A computer network is defined as a group of computers arranged together to share resources and data.
• Option 2 is about students working on a project (not related to computer network definition).
• Option 3 is about people (not computers) sharing resources.
• Option 4 is too general (a group of electronics - not specific to computers sharing resources/data).

Question 2

• A Trojan horse is a virus that hides in a seemingly good program.
• A logic bomb is a program that "explodes" when certain conditions are met (not about hiding in a good program).
• A worm is a self - replicating program that can spread across networks (not about hiding in a good program).
• An attachment virus is usually attached to an email or file (not the same as hiding in a good program).

Answer:

1. a group of computers arranged together to share resources and data.
2. a Trojan horse.
