Defining IOT 2021

1-Internet of Things Definition and Few essential Features Internet of Things (IoT) term represents a general concept for the ability of network devices to sense and collect data from around the world, and then share that data across the Internet where it can be processed and utilized for various interesting purposes. The IoT is comprised of smart machines interacting and communicating with other machines, objects, environments and infrastructures. Few features Ø   The devices in IoT can be controlled remotely to perform the desired functionality. Ø   The information sharing among the devices then takes place through the network which employs the standard protocols of communication. Ø   The smart connected devices or ‘‘things’’ range from simple wearable accessories to large machines, each containing sensor chips. For instance, the Lenovo smart shoes contain chips which provide support of tracking and analyzing fitness data . Ø   Similarly, the electri...

Physical Design of IoT-1

  It includes IoT Devices and IoT protocols- Device consist of several interfaces for connection to other devices such as § I/O interface for sensors § Interfaces for Internet Connectivity § Memory and storage interfaces § Audio/video interfaces The sensed data s either communicated to other devices or servers/ cloud based storage. The generic block diagram of IoT deviceis as follows- • USB Host   - According to the  USB (Universal Serial Bus) standard a device is classified as either a  host  or a peripheral device. In the most common scenarios the  host , such as your PC, acts as a controller and the peripheral, such as a  USB  drive, responds to its commands. • Registered jack-45  (RJ45) refers to a cable termination specification that specifies physical male and female connectors and the pin assignments of wires-in telephone cables and other networks that use RJ45 connections. RJ45 connections are also known as data jacks....
