IoT architecture refers to the structure of interconnected devices and systems in the Internet of Things, while MQTT is a lightweight messaging protocol for IoT communication.

• IoT architecture involves sensors, devices, gateways, cloud services, and applications working together.

• MQTT is a publish-subscribe protocol that allows devices to communicate over a network.

• MQTT uses topics to categorize messages and clients can subscribe to specific topics to receive relevant data.

• IoT ...read more

Computer OS network layers refer to the different levels of communication protocols used in networking.

• There are typically five network layers: physical, data link, network, transport, and application.

• Each layer has its own set of protocols and functions to facilitate communication between devices.

• Examples of protocols at each layer include Ethernet at the data link layer, IP at the network layer, and TCP at the transport layer.

Binary search implemented using recursion in C++.

• Define a recursive function that takes the array, target value, start index, and end index as parameters.

• Check the base case where start index is greater than end index, return -1.

• Calculate the mid index and compare the target value with the element at mid index.

• Recursively call the function on the left or right half of the array based on comparison.

• Return the index if target value is found, otherwise return -1.

Struct is a value type while class is a reference type in C++. Struct members are public by default, while class members are private by default.

• Struct is a value type, stored on stack, while class is a reference type, stored on heap.

• Struct members are public by default, while class members are private by default.

• Struct is used for lightweight objects with few members, while class is used for more complex objects with methods and properties.

Object-oriented programming concepts and communication between classes.

• Object-oriented programming (OOP) is a programming paradigm based on the concept of objects.

• Encapsulation, inheritance, and polymorphism are the three main pillars of OOP.

• Inheritance allows a class to inherit properties and methods from another class.

• Polymorphism allows objects of different classes to be treated as if they were of the same class.

• Communication between classes can be achieved through method ...read more

Virtual functions are functions in a base class that are overridden in derived classes to achieve runtime polymorphism.

• Virtual functions allow a function to be redefined in a derived class, while preserving its calling signature from the base class.

• They are used in object-oriented programming to achieve polymorphism, where a function call is resolved at runtime based on the actual object type.

• Virtual functions are declared using the 'virtual' keyword in the base class and ove...read more
