| When Windows Vista checks a network device's hardware settings, the wizard provides three options, what are they? |
|
Definition
1. Windows configures the device automatically If possible, Vista checks the device for compatibility and configures the device for you. So you need not provide configuration information.
2. configure this device manually, or If the device can't be configured automatically, you can select the Configure this device manually option, Vista checks the device for compatibility, but you need to configure the device yourself. You have to enter the network name and its security type.
3. create wireless network settings and save to a USB flash drive
When you select the option to save network settings to a flash drive, Vista saves the settings to the drive so that you can use the drive to configure each computer on the network with the same settings. |

Using WEP, there is one password that all users use to access the network. |
|
Definition
|
|
Term
| You set this option for security with a shared key as a password. All users attempting to access the network will need to enter this shared password. |
|

| What is the outcome of an increased range between a router and a client? |
|
Definition
| An increased range between a router and a client weakens the signal between the two, thus decreasing the data throughput and causing poor network performance. |
|
|
Term
(T/F)
When wireless networks are being set up, it is important that the router is placed in a position that is central to the clients. |
