Instruction: answer questions 31 to 40 based on the following text.
What is the internet of things?
- In the internet of things (IoT), a “thing” can be __ person with a heart monitor implant,
- __ animal with a biochip transponder, __ car with sensors to alert when tire pressure is low, or
- any object that is able to transfer data. IoT is __ system of interrelated “things” that are provided
- with __ ability to transfer information over a network without requiring human interaction. It
- uses artificial intelligence and machine learning to improve data collecting, and sometimes
- devices can even communicate with each other and then act on __ information they get.
- In agriculture, IoT-based smart farming systems can help monitor light, temperature,
- humidity, and soil moisture of crop fields; automatize irrigation systems, and collect data on
- rainfall and soil content. The infrastructure industry can benefit from sensors that monitor events
- or changes within structural buildings and bridges. To healthcare, IoT offers the ability to monitor
- patients more closely using an analysis of the data that's generated.
- Smart homes are equipped with smart thermostats, appliances, and connected heating,
- lighting, and electronic devices that can be controlled remotely via smartphones. Smart buildings
- can reduce energy costs using sensors that detect how many occupants are in a room and then
- adjust the temperature automatically. Wearable devices with sensors can be used for public
- safety, for example, by providing optimized routes to a location where there is an emergency,
- or by tracking firefighters' vital signs at life-threatening sites.
- Obviously, there are some disadvantages, too, and the list includes the risk that
- confidential information is stolen by hackers, and the difficulty for devices from different
- manufacturers to communicate with each other since there's no international standard of
- compatibility for IoT. Companies may have to deal with massive numbers, and collecting and
- managing the data from all those devices will be challenging. Ultimately, if there's a bug in the
- system, it's likely that every connected device will become corrupted.
- Pros and cons in perspective, Matthew Evans, the IoT program head at techUK, says that
- "In the short term, we know [IoT] will impact on anything where there is a high cost of not
- intervening", Evans said. "And it’ll be for simpler day-to-day issues – like finding a car parking
- space in busy areas, linking up your home entertainment system, and using your fridge webcam
- to check if you need more milk on the way home.”
