What is the purpose of a packet header in networking?

To instruct the receiving machine on how to handle the packet (correct)
To identify the source of the packet
To regulate the speed at which the packet travels
To store the entire message within the packet

How are packets transferred over the Internet?

In a linear sequence from source to destination
By being sent as a complete message from sender to receiver
In a loop formation around the globe till they reach the destination
By being processed in no particular order by routers and switches (correct)

Why is the Internet considered resilient according to the passage?

Because it operates without any protocols
Because all hardware components are replaceable
Because any piece of hardware can join or leave without affecting overall function (correct)
Because it is immune to cyber attacks
