C is a low-level programming language while Java is a high-level object-oriented language.

• C is a procedural language while Java is an object-oriented language.

• C has manual memory management while Java has automatic garbage collection.

• C is platform-dependent while Java is platform-independent.

• C supports pointers while Java does not.

• C is typically used for system-level programming while Java is used for application development.

Data structure is a way of organizing and storing data in a computer so that it can be accessed and manipulated efficiently.

• Data structures define the way data is organized and stored in memory.

• They provide efficient algorithms for accessing, inserting, and deleting data.

• Examples of data structures include arrays, linked lists, stacks, queues, trees, and graphs.

The best method in power transfers is through high voltage transmission lines.

• High voltage transmission lines are more efficient in transferring power over long distances.

• Using transformers to step up the voltage before transmission and step down the voltage at the receiving end helps minimize power loss.

• HVDC (High Voltage Direct Current) transmission is another efficient method for long distance power transfers.

• Smart grid technologies can also optimize power transfers by mon...read more

Methods to convert inverter include pulse width modulation, sine wave modulation, and square wave modulation.

• Pulse width modulation (PWM) is a common method used to convert inverter signals by varying the width of the pulses.

• Sine wave modulation involves generating a sine wave signal to mimic the output of an inverter.

• Square wave modulation produces a square wave output by switching between high and low voltage levels.

• Other methods include multilevel inverters, cascaded H-bri...read more

Behaviour refers to the way in which a person or animal acts or conducts themselves in response to a particular situation or stimulus.

• Behaviour is influenced by genetics, environment, and past experiences.

• It can be observed and measured through actions, reactions, and responses.

• Behaviour can be categorized as either innate (instinctual) or learned.

• Examples of behaviour include aggression, shyness, curiosity, and friendliness.
