Internet of Things (IoT) and Its Applications

Image
Internet of Things (IoT) The Internet of Things (IoT) is a revolutionary technology that is constantly transforming our interaction with the world around us. It allows to extend internet connectivity beyond traditional computing devices like computers or smartphones to a diverse range of everyday objects that are embedded with internet-connected sensors and actuators. This allows these objects to collect and exchange data with the network autonomously, enhancing their functionality and enabling new forms of communication between things and people, and among things as well. Core Components of IoT Devices and Sensors :  It includes smart devices, sensors, and actuators that interact with the physical world. Sensors collect data like temperature, pressure, sound, or motion, while actuators can perform actions based on received instructions. Connectivity :  Reliable and secure communication is crucial for transmitting data fr...

ARPANET : The Ancestor of Internet

Image
ARPANET : The Ancestor of Internet ARPANET stands for Advanced Research Projects Agency Network. It was an early packet-switching network and the first network to implement the protocol suite TCP/IP. The development of ARPANET marked the beginning of the digital communication era and made the foundation for today's global internet. Initialization ARPANET was funded by the United States Department of Defense through its Advanced Research Projects Agency (ARPA), created during the Cold War with Soviet. Its goal was to secure the US military's command and control systems and to connect computers at Pentagon-funded research institutions. Development Initial Concept: The original concept of ARPANET was to build a network that would allow researchers at various locations to share resources and communicate with each other efficiently. Packet Switching: Rather than using traditional circuit-sw...
