Object based focuses on using objects for data storage and manipulation, while object oriented focuses on using objects for both data and behavior.

• Object based programming languages allow for data to be stored in objects, but do not necessarily support inheritance or polymorphism.

• Object oriented programming languages support encapsulation, inheritance, and polymorphism in addition to data storage in objects.

• Examples of object based languages include JavaScript and VBScript, w...read more

Sampling theorem is a mathematical concept that states a continuous signal can be accurately represented by a discrete signal.

• It is also known as Nyquist-Shannon sampling theorem.

• It is used in digital signal processing and communication systems.

• The theorem states that the sampling rate must be at least twice the highest frequency component in the signal.

• If the sampling rate is too low, aliasing can occur, which results in distortion of the signal.

• The theorem is important in t...read more

4 stroke engines are more efficient than 2 stroke engines due to better fuel economy and lower emissions.

• 4 stroke engines have a separate intake and exhaust stroke, resulting in better fuel economy.

• 2 stroke engines have a combined intake and exhaust stroke, resulting in higher fuel consumption.

• 4 stroke engines produce lower emissions due to a separate exhaust stroke.

• 2 stroke engines produce higher emissions due to a combined intake and exhaust stroke.

• Examples of 4 stroke engi...read more
