typically used to exchange data between systems‚ nor is it regularly employed by end-user network applications (with the exception of some diagnostic tools like ping and traceroute). ICMP for Internet Protocol version 4 (IPv4) is also known as ICMPv4. IPv6 has a similar protocol‚ ICMPv6. Internet Control Message Protocol is part of the Internet Protocol Suite as defined in RFC 792. ICMP messages are typically generated in response to errors in IP datagrams (as specified in RFC 1122) or for diagnostic

It contains primarily the Internet Protocol‚ which defines the fundamental addressing namespaces‚ Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) used to identify and locate hosts on the network. Direct host-to-host communication tasks are handled in the Transport Layer‚ which provides a general framework to transmit data between hosts using protocols like the Transmission Control Protocol

1. List and describe the four types of computer networks from largest to smallest. • The four types of computer networks from largest to smallest are: WAN‚ MAN‚ LAN‚ and PAN. • WAN stands for “wide area network” this is on a global scale and can connect up to about 1 million computer networks. The areas covered can be as big as a state or a country. • MAN stands for “metropolitan area network” it is a large computer network and it can cover the distance of a whole city. • LAN stands for “local
