Which of the following statement(s) is/are true in respect of Wireless Technology?
P: Bluetooth is a wireless technology which can be used to connect a headset to a mobile phone.
Q: Bluetooth is a long range wireless technology and is a low cost means of data transfer.
P only
To determine which statement(s) regarding wireless technology is/are true, let's analyze each statement individually:
-
Statement P: Bluetooth is a wireless technology which can be used to connect a headset to a mobile phone.
- Bluetooth is a well-known short-range wireless technology that allows devices to communicate with each other. It is widely used for connecting wireless peripherals such as headsets, keyboards, and mice to mobile phones, computers, and other devices.
- This statement is accurate and describes one of the common uses of Bluetooth technology.
-
Statement Q: Bluetooth is a long range wireless technology and is a low cost means of data transfer.
- Bluetooth is indeed a low-cost means of data transfer, especially for short distances. However, it is not designed for long-range communication. Typical Bluetooth range is about 10 meters (33 feet); this can be extended slightly with certain devices, but it remains short-range compared to other technologies such as Wi-Fi or cellular networks.
- Therefore, the characterization of Bluetooth as a "long range wireless technology" is incorrect. This makes the statement partially false.
Based on the analysis above, only Statement P is true.
Conclusion: The correct answer is P only.
