a data encryption standard compliant with the IEEE802.11i standard that uses the AES (Advanced Encryption Standard) protocol. strongest
WPA2 (WiFi Protected Access 2)
1.Name the three types of Ethernet. What transmission speed does each support. (pg 404)
•100-Mbps or Fast Ethernet
•1000-Mbps or Gigabit Ethernet
2.When using dynamic IP addressing, what type of server must be on the network? (pg 419)
•DHCP (Dynamic Host Configuration Protocol) Server
3.Give an example of a classful subnet mask. Give an example of a classless subnet mask. (pg 416)
•Classful: 11111111.11111111.11111111.00000000 (
•Classless: 11111111.11111111.11110000.00000000 (
4.Which is more efficient for network traffic, a switch or a hub? Why?
•Switch, because a switch actively routes data

•WEP (Wired Equivalent Privacy)
•WPA (WiFi Protected Access)
7.What connecting device do you use for a small LAN? For two or more connected networks?
•For a small LAN network, a switch is best. To connect two or more LAN networks, a router is required.
