What can you say about a Bluetooth connection? [Discover the answer]
Here is an image illustrating the question on the Pix platform:
States What can you say about a Bluetooth connection?
It's important to check all three answers to answer the question correctly.
What's a Bluetooth connection?
Bluetooth is a technology which allows two devices to connect with each other, wireless and without the need forInternet. This connection works via radio wavesIt can be used over a short distance, generally from 10 to 100 meters, depending on device specifications. It's a great way to easily connect nearby devices such as a telephone and an speaker, a computer and an mouse, or a connected watch and one smartphone.
Why use Bluetooth?
Bluetooth can be used in many everyday situations:
- Listen to music from your telephone on a wireless speaker (for example, with an iPhone connected to a JBL speaker).
- Track your physical activity via a connected watch (such as an Apple Watch or Fitbit linked to a smartphone).
- Use a wireless keyboard or mouse with your computer (such as a Bluetooth keyboard connected to a laptop).
- Make hands-free calls in the car (for example, between a Samsung and the Bluetooth system of a Renault).
- Transferring files from one phone to another (like sending photos from a Xiaomi to an Oppo).
- In certain professional contexts, Bluetooth also facilitates data collection from sensors or mobile terminals.
In short, Bluetooth offers fast connection entre des appareils portables pour des usages quotidiens comme les périphériques ou l’audio. Voici plus d’avantages de ce système de communication radio :
- Le Bluetooth possède une faible consommation d’énergie, ce qui est utile pour les petits portable devices.
- It's easy to set up, especially for Bluetooth devices that are already linked.
- C’est une technologie qui permet l’data exchange without an Internet network.
Although the Bluetooth technology is very practical for everyday use, there are a few limitations to be aware of:
- Keep the devices close together (limited scope).
- The transfer speed is slower than Wifi.
- Il y a des risques d’interférences si plusieurs Bluetooth devices are active nearby, or if a dense wireless network interferes with the signal.
To put Bluetooth in its proper context, let's look at how it differs from other available wireless technologies.
- Wifi Bluetooth: faster and with a greater range than Bluetooth. It's ideal for transferring large amounts of data over a home or office network.
- NFC (Near Field Communication ou Communication en champ proche) : portée encore plus courte que le Bluetooth, spécialement conçu pour les actions rapides (paiement sans contact ou association automatique d’appareils).
- Infrared older technology, limited to direct, unobstructed communication between two devices.
What is Pix?
Pix is an online platform developed by the French government to assess, develop and certify digital skills. It is aimed at everyone: pupils, students, professionals and jobseekers, and offers interactive tests covering a wide range of fields. Thanks to a system of evolving questions, users can progress at their own pace and obtain a personalized profile of their skills. If required, Pix can be used to prepare a officially recognized certification. Some questions on Pix directly assess the ability to manage and secure personal data on mobile or connected devices.
In short, a Bluetooth connection allows two electronic devices to link up wirelessly and without the Internet, over short distances. It's practical, fast and widely used in everyday life, whether for transferring data or files, connecting cable-free accessories or listen to music.
