Question

It enables us to access internet securely and prevent unauthorized application and people from accessing our PC. A) Anti-virus b) security c) Firewall d) None of these

Answer 1

The answer is C) Firewall. The firewall is a software which acts as a wall between our system and the internet.

It allows only authorized connections to pass through it and blocks all other unauthorized incoming and outgoing connections.

Some may say that Anti-virus is also a correct answer and to some extent it is correct because anti-virus protections nowadays include a firewall in the package.

But when it comes to appropriate terminology, Firewall is the correct answer.
