24

• CSMA/CD
• Carrier Sense Multiple Access with Collision
  Detection

25
Simple Definitions
26

• Virtual drive
• a logical drive letter that is not physically
  located on the system. Used to do drive mappings
  between client and server. Like the K drive in
  the class lab. Points to a folder on the server.
• DNS
• Domain Name Service. A dns server translates
  names into ip number and visa versa. This is
  useful because most humans who use internet
  applications specify systems by using names, but
  the tcp/ip packets need to use ip numbers
  instead. Thus DNS servers are used to translate.
