| State and explain how disabling an SSID can increase protction for a wireless network | What allows devices to see networks names
Can be disabled
Meaning devices are unable to see the networks name |
| What does the CMSA/CS protocol cover? | carrier transmission in a wireless area network of devices in range of one another |
| What is the RTS/CTS required for? | Wireless transmission, for when devices that cannot see eachother |
| What is the purpose of wifi | Allow devises to communicate within a network without physical connection |
| How is data sent wirelessly? | Freuency through specific channels |
| What are the components required for wireless networking? | wireless network adapter
wireless access point |
| How does a wireless network adapter function | By connecting to a computers USB port or such
Picks up network broadcasts |
| What does a wireless access point do? | Device that allows other wifi devices to connect to a wired network |

| State what CTS stands for | Clear To Send |
| Why do we need both the CMSA/CS and the RTS/CTS protocols | CMSA/CS checks all the freuency of channel is clear of all devices in range
RTS/CTS is needed for devices out of range of the sending device |
| What is the CMSA/CS required for? | to stop devices sending data at the same time |
