1. Read the passage given below and answer the questions which are based on it:
The origin of computer virus is linked to an interesting game program known as ‘Core-War’ developed in AT&T’s Bell laboratories. This program worked on the programming concept of ‘self-replicating software’ and used it to devour rival’s programs instead of data. When this interesting programming concept was made public, the programmers got into the act of developing various programs based on this concept, which would penetrate someone else’s system and create havoc there. Because of their destructive nature, these programs came to be known as ‘viruses or computer viruses’. From then onwards, computer viruses have become a real menace for computer users all over the world.
A computer virus is programmed to reproduce itself very fast and swarm the computer as biological viruses do in a human body. Perhaps the most deadly similarity between the electronic and biological viruses is their tendency to spread. The computer virus does not spread by mere contact of two floppy diskettes or computers; rather the infection occurs mostly through the use of floppy diskettes which are infected by the virus. When you save or copy files to the diskettes, viruses are transferred from one source to the other, thereby, infecting other systems. When they find their way into another computer, they pollute or destroy data or valuable software and slow down the operation of the computer, or possibly stop its activities.
Other similarities with biological viruses are: 1 - The virus cannot be seen with the naked eye. To locate the virus you would need specialised software called anti-virus software. 2 - You can use the system (software/hardware or combination) as a vaccine which would protect you when the virus tries to invade the system. Even here, prevention is better than cure.

(a) The origin of computer virus is biological.
(b) A computer virus is basically a software.
