a) Why is it hard to determine how big the Internet is today? Give several reasons.
the Internet is so huge, and they re are so many URLs and sites that its almost impossible to know the amount of sites. its like a whole other world. first of all you cant track how many people have email because they don't always use the computer with the same IP address.
b) Why are TCP/IP protocols so important to the functioning of the Internet? What do they do?
when sending things, the computer sending something searches for the other computers IP address, hence the loading signal that we get while waiting for something to send. These addresses are the only thing that keep the Internet from functioning, so they are vital. there wouldn't even be an Internet with out it. other wise you would just be stuck on the same page forever.
