NodeMCU

-

NodeMCU - (MCU = stands for MicroController Unit(which really means it is a computer on a single chip))

NodeMCU is an open source platform based on ESP8266 which can connect objects and let data transfer using the WiFi protocol. 

NodeMCU is an open source firmware and development kit that helps you to prototype or build IOT products. The NodeMCU development board can be easily programmed using the Arduino IDE

Embedded System

A computer system that is integrated into a bigger device or system to carry out a specific task is known as an embedded system. It is a hybrid of hardware and software created to carry out a specific task, frequently under the restrictions of real-time computing. From basic gadgets like a microwave oven to complicated systems like aeroplanes and medical equipment, embedded systems are included in a wide variety of products. Embedded systems are often built to work in a particular context and have constrained resources, such as memory and computing power. They frequently employ real-time operating systems, specific programming languages, and specialised input/output and communication interfaces. Embedded systems are used for the specific task. They are made from microcontrollers which is the brain of the system. It is a Microcontroller - based system that is designed to control a task or range of tasks and is not meant to programmed by the end user. A microcontroller has on chip RAM, o...

What is cloud computing?

CLOUD COMPUTING AS EMERGING TECHNOLOGIES cloud computing is used for storage and access data which needs at any time. the fundamental change it brings in how we view and think about computing. To better understand the massive revolution cloud computing will bring and is bringing to the field of computing, let's first go back in time and view a similar revolution with electricity. Before the height of the industrial revolution, electricity had to be generated in house, this had many downsides: every worker lost to generating electricity was one less to make the factory more productive and scalability was a major issue, at times when production of the factory went up, there wouldn't be enough generated electricity, causing power outages and a loss of production. Thus, often times more electricity that needed was generated which was quite costly. Then in the 1880s, Thomas Edison, founded the Edison Illuminating Company, turning electricity into a utility. In other words, something...
