GENERAL KNOWLEDGE

Detailed explanation-1: -Wi-Fi Protected Access (WPA) is a security standard for computing devices equipped with wireless internet connections. WPA was developed by the Wi-Fi Alliance to provide more sophisticated data encryption and better user authentication than Wired Equivalent Privacy (WEP), the original Wi-Fi security standard.

Detailed explanation-2: -WPA (Wi-Fi Protected Access) is a wireless security protocol released in 2003 to address the growing vulnerabilities of its predecessor, WEP. The WPA Wi-Fi protocol is more secure than WEP, because it uses a 256-bit key for encryption, which is a major upgrade from the 64-bit and 128-bit keys used by the WEP system.

Detailed explanation-3: -WPA2 uses AES encryption and introduces CCMP and TKIP encryption mechanisms. Personal WPA uses a pre-shared key to check the initial credentials of users. Wi-Fi-protected access 2 pre-shared key (WPA-PSK) networks have one passphrase that is shared among all users.

Detailed explanation-4: -Wired Equivalent Privacy (WEP) is a security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b. That standard is designed to provide a wireless local area network (WLAN) with a level of security and privacy comparable to what is usually expected of a wired LAN.
