  • Define and describe IP
    Internet Protocol, is a method of efficiently moving large amounts of data between networked devices
  • In the truck analogy, what does the truck represent?
    IP
  • In the truck analogy, what does the road represent?
    The Network (DSL, Ethernet, Cable, Fiber, etc.)
  • In the truck analogy, what do the boxes (cargo) represent?
    Data, TCP and UDP
  • In the truck analogy, what is inside the boxes?
    Data/Information
  • In the truck analogy, what does the house number and room represent?
    The IP address and port number, respectively
  • Define and describe a MAC address
    Medium/Media Access Control, is a unique identifier assigned to a NIC (Network Interface Controller, sic Network Card)
  • Define and describe TCP
    Transmission Control Protocol is a connection-oriented protocol that relies on a formal connection between two devices, TCP can provide error detection and correction, and can rearrange messages that are out-of-order or retransmitted
  • Define and describe UDP
    User Datagram Protocol is a connectionless protocol that sends a continuous stream of information without error recovery or data restructuring
  • What is a common reason to use UDP over TCP?
    Real-time communications
  • Which protocol utilizes return receipts?
    TCP
  • Define and describe non-ephemeral ports
    Permanent port numbers reserved for critical protocols, Ports 0-1,023, usually on a server or service
  • Define and describe ephemeral ports
    Temporary port numbers for temporary usage, Ports 1,024-65,535, usually determined in real-time by the client
  • True or False: TCP and UDP ports have predetermined sets of ports they can use
    False - TCP and UDP ports can be any number 0-65,535
  • True or False: Most servers use non-ephemeral port numbers
    True
  • How are well-known ports useful for security?
    They can be given special firewall permissions
