  16. (TCO 2) _ is a 1-bit flag in the TCP header that is used to request from the higher layers an immediate delivery of the packet. (Points : 5)
  17. (TCO 2) _ are the values between 1,024 and 49,151. These numbers are equivalent to well-known ports in concept, but they are specifically used for nonprivileged applications and user processes. (Points : 5)
  18. (TCO 2) Binary digit 11111111 is decimal number _. (Points : 5)

  21. (TCO 3) The 8-bit _ field describes the maximum hops the packet can take before it is considered lost or undeliverable. (Points : 5)
  22. (TCO 3) The _ is a routing table entry used to direct packets for which a next hop is not explicitly listed in the routing table. (Points : 5)
  23. (TCO 3) _ are protocols used between routers so that they can learn routes to add to their routing table. (Points : 5)
  24. (TCO 4) _ is where a station can transmit and receive communication at the same time and there are no collisions with this Ethernet transmission. (Points : 5)
  25. (TCO 4) _ is the term describing a device communicating at Layer 2 of the OSI Model. (Points : 5)
  26. (TCO 1) The _ is the network that combines enterprise networks, individual users, and ISPs into a single, global IP network. (Points : 5)
  27. (TCO 1) _ is a numbering system characterized by 1s (on) and 0s (off). (Points : 5)
  28. (TCO 1) A(n) _ is a collection of computers, printers, routers, switches, and other devices that can communicate with each other over some transmission medium. (Points : 5)
