  1. 1. How does the access method used by Wi-Fi differ from that used by Ethernet?
    Wi-Fi uses Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA). Unlike Ethernet, that detects collisions and then recovers from them, CSMA/CA tries to avoid collisions.
  2. 2. What happens if an 802.11g device detects an 802.11b device nearby?
    The 802.11g device drops into a lower-speed operating mode.
  3. 1. What are the two protocols that support VPN connections over the Internet?
    PPTP and L2TP
  4. 2. What authentication protocols are supported for PPP connections?

    • 1. What are the connection methods supported for circuit-switched networks?
    • Circuit-switched: POTS and IDSN
  5. 1. What are the connection methods supported for dedicated circuit networks?
    Dedicated circuit: T carrier and SONET (SDH)
  6. 1. What are the connection methods supported for packet-switched networks?
    Packet-switched: X.25, ATM, Frame Relay, and SMDS
  7. 2. What are the architectures supported by circuit-switched networks?
    Circuit-switched: cloud
  8. 2. What are the architectures supported by dedicated circuit networks?
    Dedicated circuit: ring, star, and mesh
  9. 2. What are the architectures supported by packet-switched networks?
    Packet-switched: cloud
  10. 1. Name three types of applications available for a smartphone.
    Productivity applications, communications, personal management, health and fitness, and entertainment are several application types that are available on a smartphone.
  11. 2. What services can you think of that you already access through cloud computing?
    • Some cloud computing services include:
    • • Software as a service (SaaS)
    •  o Customer resource management via
    • o E-mail like Hotmail, YahooMail or Gmail.

    • • Development services
    • o Application development via

    • • Utility services
    • o Antivirus protection via Panda Cloud Antivirus.

    • • Commerce services
    • o Purchasing items from eBay.

    There are many cloud computing services, so students answers will vary greatly.
