Sharing or file transfer is an activity that is now a habit of modern society. This habit is none other than due to the development of technology and information science which is progressing from time to time. Therefore, many companies are taking advantage by creating software applications that are able to move or transfer files easily.

Before we got to know an Android cellphone, there must be no stranger to the name infrared or better known to the public as infrared. Infrared is the first application that can be used on a cellphone (handphone) that can transfer files from one device to another.

Infrared is a file transfer application that uses infrared light transmission media as an intermediary for its transfer. Infrared is created in two versions or models that have different speeds. The first version has a speed of 2.4 Kbps - 115.2 Kbps.

While the second version or model has a higher speed than the first version, namely 0.576 Mbps - 1.152 Mbps. So it can be said that the second version has 10 times the speed of the first version. The inventor of infrared itself was Herschel in 1800 in various systematic experiments aimed at providing a reduction in heat. Infrared itself was first created in 1840 by the son of infrared inventor, Sir John Herschel. He is a very famous professor, especially in the field of astronomy. However, along with the development of the era infrared began to be displaced by the emergence of a new file transfer application, namely Bluetooth.

Bluetooth is a wireless-based file or data transfer application that uses the ISM 2.4 GHz radio frequency to connect one device to another with a relatively short range. Bluetooth was first released in 1999 which was a development of various large companies such as Ericsson, Nokia, Toshiba, IBM, Intel which later formed a group called SIG (Special Interest Group). Since then, many large companies have joined GIS, even companies such as Microsoft and Motorola have also joined. To date, more than 1800 companies from various parts of the world have joined GIS.

Bluetooth only has a relatively short range of 10 meters from the original device. Bluetooth has a speed that exceeds infrared, reaching 3 Mbps. However, recently the community was again surprised by the presence of a new file transfer application, namely SHAREit.

SHAREit is an application developed by Lenovo which functions to transfer files be it images, videos, music and even applications that have large capacities. SHAREit, the world's first Cross-platform and close-range file transfer tool. SHAREit uses a LAN (local area network) or wifi as an intermediary.

Even though it uses wifi or hotspot, SHAREit APK Download is an application that is free of cost or internet quota, aka free. All because the system reverses the use of wifi and hotspots. If we want to send files then we have to activate wifi whereas if we want to receive files we have to activate the hotspot. Even now SHAREit has been downloaded by more than 600 million users. For transfer speed even up to 20 Mbps or 20 times faster than Bluetooth.

The following are features of the use of SHAREit, including:

• No internet restrictions. So it doesn't require internet access to activate this application.
• Send and receive quickly without compression.
• Even speeds up to 20 times that of
• Cross-platform. Can be used for various devices such as mobile phones, computers, tablets, and android, iOs, windows phone, windows XP / 7/8.
• Share any files. From files to large applications you can.
• The operation is very easy.

So from the three applications, it can be concluded that SHAREit is the fastest file transfer application today. For cellphone, computer, tablet, as well as android and iOs users, SHAREit is a mandatory application that must be on your device. So much info about infrared, Bluetooth and SHAREit applications at this time. Hopefully it can add information for you readers. Greetings tecnobaile future greetings to us technology generation.
