One of the most vital thing that has done this along with internet is iot or internet of things. The process has been more successful for the wireless communication.
 The Internet of Things (IoT) is the continuing development of the Internet that allows everyday objects embedded with electronic devices to send and receive data over the Internet. It promises to connect all types of devices from computers to smartphones to watches to any number of everyday devices.
Today billions of devices are connected to internet and we are calling this term as internet of things. Internet of things is referred to a term that is connected to our everyday using devices to all sensors and to many electronic devices. It can collect and receive data for improving many things. Many large organizations collect this information of their client to make their service more better. IoT brings the organizations closer to their customers.
In spite of all the good sides the internet of things has some security issue. For IoT sometimes customers are not safe. Sometimes personal data goes to security brokers. It is really risky that all of your personal data has been leaked to a person who is totally unknown to you and even you can’t find him who is it or even you might don’t know who can do any bad to you with this information they have. They have collected all the information from your devices that you use in your everyday life it may be your mobile phone or smart watch or your computer. So we must be careful about the security issue.
