Wireless Networks

One of the following is NOT a reason to have wireless network connectivity:

• Mobility
• Productivity
• Reduced cost
• Get more stable connection

One of the following is NOT correct about WLANs:

• Uses access points for connections
• Used by battery powered devices
• Used by plugged-in devices
• Uses Radio frequencies

Which two standards of the following CANNOT work together

• 802.11a and 802.11b
• 802.11a and 802.11n
• 802.11b and 802.11g
• 802.11b and 802.11n

Data rate provided by 802.11g standard is:

• 11 Mbps
• 54 Mbps
• 100 Mbps
• 210 Mbps

It is the process by which the characteristics of electrical signals are transformed to represent information:

• Modulation
• Processing
• Channels
• Frequencies

It is one of modulation techniques that provides faster data rates:

• OFDM
• DSSS
• OFDS
• DSSM

DSSS modulation technique is NOT working with one of the following standards:

• 802.11a
• 802.11b
• 802.11g
• 802.11n

It is a wireless component that encodes data stream into RF signals:

• Wireless Access Point
• Wireless NIC
• Wireless Router
• None of those devices

One of the following is NOT the job of Wireless NIC:

• Setup WALN configurations
• Do modulation
• Provide connectivity to wireless network
• Has the same job of Network adapters

802.11 Standards used by wireless router is configured through:

• Wireless network mode
• Wireless network name
• Wireless network channel
• Wireless SSID broadcast
