  1. Internet Control Message Protocol (ICMP)
    Protocol in which messages consist of a single packet and are connectionless.  ICMP packets determine connectivity between two hosts.
  2. Transmission Control Protocol(TCP)
    Part of the TCP/IP protocol suite, operates at Layer 4 (Transport) of the OSI seven-layer model.  TCP is a connection-oriented protocol.
  3. User Datagram Protocol (UDP)
    A protocol used by some older applications, most prominently TFTP(Trivial FTP), to transfer files, UDP datagrams are both simpler and smaller than TCP segments, and they do most of the behind-the-scenes work in a TCP/IP network.
  4. HTTP (Hypertext Transfer Protocol)
    Extremely fast protocol used for network file transfers on the World Wide Web.
  5. Address Resolution Protocol (ARP)
    A protocol in the TCP/IP suite used with the command-line utility of the same name to determine the MAC address that corresponds to a particular IP address.
  6. Classless Inter-Domain Routing (CIDR)
    Method of categorizing IP address in order to distribute them.
  7. Packet
    Basic component of communication over a network.  A group of bits of fixed maximum size and well-defined format that is switched and transmitted as a complete whole through a network.  It contains source and destination address, data, and control information.
  8. Subnetting
    Taking a single class of IP addresses and chopping it into multiple smaller groups.
