Answer to Question 1

Supply chains benefit from sensing technologies that improve visibility during transit and in storage. RFID chips are especially useful in supply chains. Attached to packages or crates, they can transmit data as they pass by readers at seaports, railway stations, or warehouses.
For high-risk supply chains, organizations use a combination of sensors and tracking software. Global positioning systems (GPS) are a critical feature of navigation and transportation systems. These devices receive signals from 32 orbiting satellites that transmit time and location data, and the GPS receiver computes its own 3-dimensional location based on distances from the three or four closest satellites. Location is accurate within a few meters. GPS devices help drivers navigate to their destinations and keep managers apprised of their fleets. Live GPS tracking software shows the speed and location of every vehicle overlaid against live traffic maps.

Answer to Question 2

The computer obtains the public key of the Web site to which it will connect. Then it generates a key for symmetric encryption. It encodes that key using the Web site's public key. It sends the encrypted symmetric key to the Web site. The Web site then decodes the symmetric key using its private key. From that point forward, the computer and the Web site communicate using symmetric encryption.
