Translate the following passage into Chinese.How Can an Individual Surf Safely at a Public Wi-Fi Hotspot?First, install Internet security software that includes antivirus, local firewall, and intrusion protection.Next, know the name of your Wi-Fi provider, create a unique username for that connection, and use a complex password comprised of random letters and numbers. When connecting through a logon page, view the site’s certificate presented by the browser to verify that the site is operated by the expected organization.In addition, turn off file and printer sharing to make it harder for a stranger to check your wireless activities, and avoid sending any confidential information (Social Security numbers, bankaccount passwords, and so on) over a Wi-Fi connection.

For example, you can use a geofencing app to turn off your Wi-Fi when you are out of range of a network (for security reasons and to save your battery) or an app to remind you of tasks you need to accomplish when you enter or exit a specific geofence. And a new Nearby service from Wikipedia displays Wikipedia articles based on people’s current location hopes that these individuals will upload photos and otherwise update content9 their smartphones. Geofencing possibilities are growing and appear to beonly 10 by developers’imaginations.
