Friends, today everyone will definitely have a mobile tablet or laptop and sometime, to send any data to another mobile, some application or such wireless technology must have been used which can send data at very high speed, to other mobiles and laptops. Applications like Share it, Share me, Xender, Clone phone etc. are used to transfer data and when we talk about wireless technology, Wi-Fi and Bluetooth are used to transfer data. The applications that use to transfer data also use wireless technology like Wi-Fi and Bluetooth to transfer data and due to this application we do not have to do much frills.
What is Wi-Fi ?
Wi-Fi is an acronym which stand for Wireless Fidelity. It used for Internet and network connections. Wi-Fi was invented by John O' Sullivan and John Deane in 1991. Wi-Fi is also known as WLAN(Wireless Local Area Network). Due to the Wi-Fi, all devices like mobile, laptops, tablets, computers, printers and device which come with Wi-Fi facility can connect with each other. Wi-Fi is a local area network within which any device can be connected to it. Whenever a device does wireless communication, it is a two-way communication, for example your computer is connected to Wi-Fi, then your Wi-Fi adapter converts the data into a radio signal and then sends it to the router with the help of an antenna. And the router sends it to the Internet with the help of a physical wire connection and in this way data can be sent from one device to another.
Advantage of Wi-Fi
- Wi-Fi help to connect two or more devices with each other.
- A device which come with Wi-Fi can use internet and can share data.
- The rate of transfer of data with the help of Wi-Fi is 1mbps to less than 54mpbs.
Disadvantage of Wi-Fi
- Wi-Fi adapter is costly than Bluetooth adapter.
- Wi-Fi use radio wave to connect with other devices which is harmful for human. it can cause diseases like insomnia, Cancer etc.
What is Bluetooth ?
Like Wi-Fi, Bluetooth is also a wireless technology, which helps two or more devices to communicate without a wire. The name Bluetooth was derived from the King of Herald Bluetooth and it was created by Jaap Haartsen in 1994. To establish a connection in Bluetooth, a special pin is needed which makes it secure, then only after that two devices can connect. seven device can connect with each other at a time via Bluetooth. Compared to other wireless technologies, the data transfer rate in Bluetooth is slightly slower, due to which it is used to share files of small size. Two devices can be connected with the help of Bluetooth within a radius of 10 to 100 meters, If you go farther than this, both the devices will be disconnected. Bluetooth has been improved and developed from time to time, due to which many versions of it have been launched in the market such as Bluetooth v1.0, v2.0, v3.0, v4.0, v4.1 and v5.0 which is its latest version of Bluetooth
Advantage of Bluetooth
- Bluetooth allow to connect a device with each other.
- Bluetooth consume very less power due to which your battery life can optimized.
- Bluetooth allow to share data and internet.
Disadvantage of Bluetooth
- If Bluetooth is turned on and kept on, then it consumes power.
- Data transfer speed in Bluetooth is also very low.
- Can connect Bluetooth within a very short range.
Uses of Wi-Fi and Bluetooth :
Wi-Fi and Bluetooth is both the popular wireless technology which is being used in all the devices so that we can control any device while sitting. Inbuilt Wi-Fi and Bluetooth adapters are available in all gadgets like mobiles, laptops, tablets, etc., due to which the cost of buying them is also saved. Bluetooth is used in things like cameras, speakers, headphones, tablets, mobile data sharing, internet connectivity, etc., and Wi-Fi is used for things like internet connectivity, network connections, data sharing, Wi-Fi calling, Wi-Fi, charging, GPS, etc.
