Chapter 5 Emerging Technologies

The purpose of a digital system is to

• provide data to the user.

• transform data into information.

• consist of hardware and software.

• allow data and information to be stored.

A smart phone

• is a mobile telephone.

• does not use microcontrollers or microprocessors.

• is a mobile telephone integrated with a digital system.

• includes an operating system and web browsing but not email.

Drones include actuators which are used to

• provide GPS coordinates.

• provide position and movement sensors.

• control movement in the propellers and motor.

• allow the drone to fly on a set route via several waypoints.

A group of nanosatellites that are launched into orbit and then work together to complete tasks is known as a

• herd.

• flock.

• wasp.

• swarm.

A benefit of a 3D printer is that it helps organisations save time and money as they can often skip the step where

One emerging use of wearable technology is that

• drones can be worn.

• robotics are replacing humans in the workplace.

• workplace health and safety issues can be monitored.

• swarms can take satellite images of the Earth’s surface.

Organisations can also save money on power and utility costs by using IoT devices to

• control energy systems.

• increase the temperature in the buildings that they operate.

• collect data about a user’s activity without the user’s knowledge.

• control energy systems to ensure they run efficiently and avoid unnecessary usage.

An example of a cognitive aid is a

• wheelchair.

• memory game.

• home automation system.

• personal response system.

Secret questions form part of

• fraud detection.

• virtual currencies.

• multi-factor authentication.

• blockchain technology.

A database where an identical copy is stored on multiple digital systems is known as

• a blockchain.

• a virtual currency.

• an electronic funds transfer.

• a near-field communication.
