TCP/IP stands for Transport Control Protocol/Internet Protocol suite
 IP - The Internet Protocol is a network layer protocol that moves data between host computers
 IPv6 is the next generation protocol for Internet Protocol (IP) networking
 TCP - The Transport Control Protocol is a transport layer protocol that moves multiple packet data between
applications
 UDP - The User Datagram Protocol is a transport layer protocol like TCP but is less complex and reliable
than TCP
 ICMP - The Internet Control Message Protocol carries network error messages and other network software
requirements
Comment: This protocol family is used by many networks especially the Internet because…….
SUMMARY – describe why protocols are important (in your words not mine)
Eg. Protocols are needed so that different networks and computer system can talk to each other otherwise the
Internet would not exist and there would be no such thing as a WAN. As each system is designed, such as email
then in order for us to connect and send and receive we need to be sure that the computer languages and
programs used are compatible.
Other things protocols help with:
Different network types and generations
Message integrity; error checking, data resending, addressing of ports
