Question

Quizplus · Accepted Answer

A symbol represents a change in the signal and is equivalent to one baud.

Answer: D 
 Intersymbol interference occurs when consecutive symbols in a digital signal interfere with each other, causing errors in transmission.

Answer: I 
 TKIP (Temporal Key Integrity Protocol) is a security protocol used in Wi-Fi networks to encrypt data and prevent unauthorized access.

Answer: G 
 Spatial multiplexing is a technique used in MIMO (Multiple Input Multiple Output) wireless systems where multiple antennas are used to transmit and receive multiple data streams simultaneously.

Answer: C 
 A guard band is a frequency band that separates two adjacent frequency bands to prevent interference between them.

Answer: F 
 Reduced interframe space is a technique used in Wi-Fi networks to reduce the delay between frames, allowing for faster data transmission.

Answer: J 
 A wireless controller is a device used to manage and control multiple access points in a wireless network.

Answer: A 
 Co-channel interference occurs when multiple devices transmit on the same frequency channel, causing interference and reducing network performance.

Answer: E 
 A pre-shared key is a method of securing a wireless network by using a shared password or passphrase that must be entered to access the network.

Answer: B 
 CTS-to-self is a mechanism used in Wi-Fi networks to prevent hidden node problems and ensure reliable transmission.
