Inheritance is a mechanism in Java where a class acquires the properties and methods of another class.

• A subclass can inherit properties and methods from a superclass

• The keyword 'extends' is used to create a subclass

• A subclass can override methods of the superclass

• Java does not support multiple inheritance, but it can be achieved through interfaces

Polymorphism is the ability of an object to take on many forms.

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

• It can be achieved through method overloading or method overriding.

• Example: A shape class can have different subclasses like circle, square, triangle, etc. and all can be treated as shapes.

• Polymorphism helps in achieving code reusability and flexibility.

OS stands for Operating System. It is a software that manages computer hardware and software resources.

• OS is the interface between the user and the computer hardware.

• It manages memory, processes, and input/output devices.

• Examples of OS include Windows, macOS, Linux, and Android.

• Types of OS include single-user, multi-user, real-time, and embedded.

• OS can be classified based on their architecture, such as 32-bit or 64-bit...read more

A bandpass filter is a type of electronic filter that allows a specific range of frequencies to pass through while blocking others.

• It is used to separate a specific frequency range from a signal.

• It consists of a combination of low-pass and high-pass filters.

• It is commonly used in audio and radio frequency applications.

• Examples include tuning circuits in radios and audio equalizers.

• Bandwidth and center frequency are imp

Cutoff frequency is the frequency at which a filter attenuates a signal by half its power.

• Cutoff frequency is a characteristic of filters used in signal processing.

• It is the frequency at which the filter starts to attenuate the signal.

• For low-pass filters, frequencies below the cutoff frequency are passed through, while frequencies above are attenuated.

• For high-pass filters, frequencies above the cutoff frequency are p...read more

SDLC stands for Software Development Life Cycle, which is a process used to design, develop, and maintain software.

• SDLC is a structured approach to software development.

• It involves several stages such as planning, designing, coding, testing, and maintenance.

• Each stage has its own set of activities and deliverables.

• The goal of SDLC is to produce high-quality software that meets the customer's requirements.

• Examples of SD

32-bit processors can handle 2^32 bits of data at a time, while 64-bit processors can handle 2^64 bits of data at a time.

• 32-bit processors can address up to 4GB of RAM, while 64-bit processors can address much more.

• 64-bit processors are generally faster and more efficient than 32-bit processors.

• 64-bit processors can run both 32-bit and 64-bit applications, while 32-bit processors can only run 32-bit applications.

• 64-bit...read more
