Signs and symptoms of E. coli O157:H7 infection typically begin three or four days after exposure to the bacteria, though you may become ill as soon as one day after to more than a week later. Signs and symptoms include:
WPA - Wi-Fi Protected Access. Definition: WPA is a security technology for Wi-Fi wireless computer networks. WPA improves on the authentication and encryption features of WEP (Wired Equivalent Privacy). In fact, WPA was developed by the networking industry in response to the weaknesses of WEP.
Wi-Fi Protected Access v2 (WPA2). WPA2 is the current security standard that all wireless networks should use. WPA2 added support for a much stronger encryption method, AES. This solved the flaws that the TKIP encryption method provided in the WPA protocol.EP was the original security algorithm that was developed for use with 802.11. It is supported on almost every 802.11a/b/g/n wireless device. There are two versions of WEP, 64-bit or 128-bit. 64-bit WEP uses a 40-bit key, and 128-bit WEP uses a 104-bit key.
