Answers
Answer:
1) System software is meant to manage the system resources. It serves as the platform to run application software. Application software helps perform a specific set of functions for which they have been designed. Application software is developed in a high-level language such as Java, C++, .
2)Worms spread from computer to computer, but unlike a virus, it has the capability to travel without any help from a person. ... A Trojan horse is not a virus. It is a destructive program that looks as a genuine application. Unlike viruses, Trojan horses do not replicate themselves but they can be just as destructive.
3)Viruses may have arisen from mobile genetic elements that gained the ability to move between cells. They may be descendants of previously free-living organisms that adapted a parasitic replication strategy. Perhaps viruses existed before, and led to the evolution of, cellular life.
