What is the purpose of a firewall in a computer network?

How often should passwords be updated according to the document?
At least every quarter.
Only when you forget them.
Once every five years.
Never, if they are strong.
Why is it a bad idea to substitute letters with similarly shaped characters in passwords, like 'pa$$w0rd' for 'password'?
Because hackers are onto that trick and it does not provide real security.
Because it makes passwords too long to remember.
Because it makes passwords incompatible with most websites.
Because it makes passwords case-sensitive.
What is the risk of not performing regular updates of your anti-virus software?
