It’s incredibly easy to overlook how profoundly the world has changed over the last couple of decades.Not long ago, before the Internet,mobile devices and cloud applications existed , data resided mostly on gigantic mainframes and , later, on the hard drives of personal computers.Most of these machines were little more than stand-alone islands in a vast sea of computers. Getting data from one device to anotrher was no simple task.
The “Internet of things” (IoT) is becoming an increasingly growing topic of conversation both in the workplace and outside of it. The Internet of Things is creating a new world, a quantifiable and measureable world, where people and businesses can manage their assets in better informed ways, and can make more timely and better informed decisions about what they want or need to do. This new connected world brings with it fundamental changes to society and to consumers. By sensing our surrounding environment, the IoT will create many practical improvements in our world, increasing our convenience, health and safety, while at the same time improving energy efficiency and comfort. The IoT will be a new source of wealth creation.
IoT describes a system where items in the physical world, and sensors within or attached to these items, are connected to the Internet via wireless and wired Internet connections. These sensors can use various types of local area connections such as RFID, NFC, Wi-Fi, Bluetooth, and Zigbee. Sensors can also have wide area connectivity such as GSM, GPRS, 3G, and LTE.
