Answer by student:
a. PAN
Detailed answer by teachoo:
To answer this question, we need to know the definitions and examples of different types of networks based on their size and scope. There are four types of networks:
- Personal Area Network (PAN) : A network that connects devices within a very short range, typically a few meters. Examples are Bluetooth devices, infrared devices, wireless keyboards, etc.
- Local Area Network (LAN) : A network that connects devices within a small area, such as a room, a building, or a campus. Examples are computers, printers, scanners, routers, switches, etc.
- Metropolitan Area Network (MAN) : A network that connects devices within a large area, such as a city or a town. Examples are cable TV networks, broadband networks, etc.
- Wide Area Network (WAN) : A network that connects devices across a very large area, such as a country or a continent. Examples are the internet, satellite networks, cellular networks, etc.
In this question, Riya wants to transfer pictures from her mobile phone to her laptop. She uses Bluetooth technology to connect the two devices. Bluetooth is a wireless technology that enables short-range communication between devices. Therefore, the type of network that will be formed in this case is a Personal Area Network (PAN).
Let’s go through each of the options and see why they are correct or incorrect:
- a. PAN: This is correct because it matches the definition and example of a Personal Area Network.
- b. LAN: This is incorrect because it is a network that connects devices within a larger area than a PAN. Riya’s mobile phone and laptop are not connected to any other device or server in a LAN.
- c. MAN: This is incorrect because it is a network that connects devices within a city or town. Riya’s mobile phone and laptop are not connected to any other device or network in a MAN.
- d. WAN: This is incorrect because it is a network that connects devices across a very large area. Riya’s mobile phone and laptop are not connected to the internet or any other WAN.
So, the correct answer is a. PAN.
