What is the purpose of a swap function in programming?

To exchange the position of two values at specified indexes in a list.

What is the disadvantage of the open standard of Internet addressing?

It makes it easy to censor websites and is vulnerable to denial of service attacks.

In public-key encryption, who encrypts the message with the recipient's public key?

What is the main concept of lossy compression?

It loses some data and cannot perfectly reconstruct the original data.

What statement describes calculating the sum of a list with improper initialization of a sum variable?

It resets and only displays the last item value.

What will happen to the original data when using lossy compression?

Some data will be permanently lost.
