The Logic OR Gate is a type of digital logic circuit where output goes HIGH (to a logic level 1) only when one or more of its inputs are HIGH (or 1). The output of a Logic OR Gate only returns LOW when ALL of its inputs are at a logic level 0. In other words, for a logic OR gate, any HIGH input will give a HIGH, logic level 1 output.

Output of A and 1 = 1 (Q₁)
Output of B and 1 = 1 (Q₂)
Output of Q₁ and Q₂ = C = 1

Collaborative filtering is a recommendation system that creates a prediction based on a user's previous behaviors. It is a method of making automatic predictions about the interest of a user by collective preferences. It is the most common technique used when it comes to building intelligent recommender systems. Most websites like Amazon, YouTube, and Netflix use collaborative filtering as a part of their sophisticated recommendation systems.

Wearable devices such as smartwatches can identify the location of a person by tracking GPS. Smartwatches and Fitbit devices can also monitor heart rate and the sleeping pattern of a person. For assisting hearing-impaired persons, hearing aid wearable devices are more common and older than smartwatches popular today.

The Internet of Things (IoT) is an emerging topic of technical, social, and economic significance. IoT is the network of physical objects – devices, home appliances, cars, and trucks, industrial and utility components, and other everyday objects embedded with electronics, software, sensors, and network connectivity and powerful data analytic capabilities that promise to transform the way we work, live, and play. These devices can communicate and interact with others over the internet and they can be remotely monitored and controlled.

5G Technology stands for Fifth Generation, which is the next generation of wireless network technology, designed to broaden the reach of mobile technology beyond LTE's capabilities. It is the most recent version of cellular technology. 5G is distinguished by three key characteristics: faster speeds, lower latency, and the ability to connect many devices at the same time. 5G unlocks the true potential of edge computing with its low latency and high bandwidth capabilities. 5G can help to reduce the time it takes for IoT (Internet of Things) devices and edge servers to communicate with each other, enabling real-time processing of data at the edge. Network slicing is another feature of 5G networks, which creates dedicated virtual networks for IoT devices to provide better network performance and security.

Vidya Vahini project involves taking computer education to primary government schools across the country.

The minimum number of NAND gates required to implement an Ex-OR function is 4.
