27. How Does It Work?

29. • The Internet is based on TCP/IP protocol and the
packet-switching technology.
• Transmission control protocol (TCP) is responsible
for breaking up messages into sequences of
packets, each approximately 1500 bytes.
• It makes and breaks the connection between
computers on the Internet, whereas the Internet
Protocol (IP) takes care of routing the data
packets on the Internet.
• At the destination, the TCP software reassembles
these packets into complete messages.

translate it into an equivalent IP address of
192.231.207.100.
