Read the passage and answer the questions that follow (16 - 21):
Smart home technology is becoming more and more popular. This technology connects different devices in your home to the internet and to each other. A smart home is a house where you can control lighting, heating, and even your coffee machine using your voice or an app on your smartphone. For example, if you are on your way home from work, you can turn on the heating with your phone. The house will be warm when you arrive.
One of the biggest advantages is convenience. A person who is busy can save a lot of time. If you forget to turn off the lights, you can do it from anywhere. This also helps save energy. In addition, smart homes can improve safety. There are smart locks which you can lock or unlock remotely, and security cameras that send an alert to your phone if they detect movement. For people who are elderly or have disabilities, this technology is very helpful. They can ask a smart assistant to make a call if they have an emergency.
However, there are also some disadvantages. Firstly, smart home devices are often expensive to buy and set up. Secondly, they depend on a good internet connection. If the internet stops working, you might not be able to control your devices. Another problem is security. Hackers might try to access the system which controls your home. As a result, companies which produce these devices are always working to make them safer. If they solve these problems, maybe every home in the future will be a smart home.
