Answer 1

What is computer networks?

A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes.

Briefly explain network application GPS and RFID.

RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person. Passive RFID uses a reader that transmits a very powerful low-frequency RF signal to an RFID sticker.

GPS (Global Positioning System) helps to track the objects within the buildings and over the geographic area with the help of tags and protocols. These protocols help to track the objects in a secure way and also provide authentication to access the object.

GPS uses a signal processor to receive low-power satellite signals and calculate positioning.

How UBER and DHL using GPS and RFID applications in their business model discuss the case

Uber's service is built around their smartphone app used by both drivers and customers, which gives them an opportunity to collect GPS, gyroscope and accelerometer data during Uber trips. Data is constantly collected during trips and sent to Uber's servers for processing and long-term storage. Uber Nav pulls GPS data from several systems, like Google Maps, Bing Maps, and TomTom, for a more comprehensive navigation experience. This means less chance of mess-ups from the navigation system, even in city driving.

DHL, one of the leading express delivery and logistics company, in partnership with Microlise and AeroScout, has developed a dynamic new system for the pharmaceutical industry which enables the real-time monitoring of product shipment temperatures throughout an extended supply chain using RFID sensors.

DHL, Microlise and AeroScout partnered with a Healthcare Company to develop a system that will help customers better meet temperature compliance regulations set within the pharmaceutical industry. With this system, full real-time visibility of the location and temperature of the pharmaceutical shipments throughout the supply chain has been made possible, through a web browser linked to the Microlise Transport Management Centre (TMC) software. The TMC enables real time tracking of the vehicle position along with the temperature indication from the Wi-Fi-based AeroScout Active RFID tags which are used to monitor the shipments.
