5. _____This OSI layer divides a file into segments that are an efficient size for routing.

6. _____This is an application protocol that uses the Internet's TCP/IP protocols to transfer Web page files to a server. It's also used to download programs and other files from a server to your computer.

7._____ Unlike TCP, this alternative method of data exchange does not provide the service of dividing a message into packets and reassembling it at the other end, but instead relies on the application program to make sure that the entire message has arrived and is in the right order.

8._____ This was set up in 1994 to form a network within the Internet that could use TCP/IP to transmit multicasts of audio and video data in much the same way that radio and TV programs are broadcast over airwave.
