Modulation is the process of varying a carrier signal's properties to transmit information efficiently.
Modulation is used to transmit information over long distances.
It allows multiple signals to be transmitted simultaneously without interference.
Modulation helps in improving the signal quality and reducing noise.
Different modulation techniques include amplitude modulation (AM), frequency modulation (FM), and phase mod...
The program counter is a register that keeps track of the next instruction to be executed in a computer program.
The program counter is a special register in a computer's central processing unit (CPU).
It holds the memory address of the next instruction to be executed.
After each instruction is executed, the program counter is incremented to point to the next instruction.
In case of conditional or unconditional jumps, the ...
A latch is level-sensitive and stores data as long as the enable signal is active, while a flip flop is edge-triggered and stores data only on the rising or falling edge of the clock signal.
Latches are level-sensitive, while flip flops are edge-triggered.

Op-amps are widely used in various applications such as amplifiers, filters, oscillators, and
There are no classes in C as it is a procedural programming language.
C is a procedural programming language, not an object-oriented one.
It does not have the concept of classes or objects.
Instead, it uses functions and structures to organize code.
Structures can be used to create user-defined data types.
For example, a structure can be defined to represent a person with attributes like name, age, and address.

Big Data refers to large and complex datasets that cannot be easily managed or processed using traditional data processing techniques.
Big Data is characterized by the 3Vs: Volume, Velocity, and Variety.
Volume refers to the vast amount of data generated and collected from various sources.
Velocity refers to the speed at which data is generated and needs to be processed in real-time.
Variety refers to the different types a...

OOP is a programming paradigm that uses objects to represent and manipulate data and behavior.
Encapsulation: bundling data and methods together in a class
Inheritance: creating new classes from existing ones
Polymorphism: using a single interface to represent different types
Abstraction: simplifying complex systems by breaking them into smaller, manageable parts
Early binding and late binding are two different approaches to linking functions or methods to their respective code.
Early binding is done at compile-time, where the function call is resolved before the program is executed.
Late binding is done at runtime, where the function call is resolved during the program's execution.
Early binding provides better performance as the function call is already resolved.
Late binding all...
Functions are blocks of code that perform a specific task and can be reused throughout a program.
Functions are used to break down a program into smaller, manageable parts.
They improve code reusability and modularity.
Functions can take input parameters and return output values.
Examples of functions include calculating the square root of a number or sorting an array.
Functions are used in a program to modularize code, improve code reusability, enhance readability, and simplify debugging.
Functions help break down complex tasks into smaller, manageable parts.
They promote code reusability by allowing the same code to be used multiple times.
Functions enhance code readability by organizing code into logical blocks.
They simplify debugging as errors can be isolated and fixed within a spec...
An abstract class in Java is a class that cannot be instantiated and is used as a blueprint for other classes.
An abstract class can have both abstract and non-abstract methods.
It can have abstract methods without any implementation.
It can also have non-abstract methods with implementation.
Abstract classes are meant to be extended by other classes.
To use an abstract class, it must be extended and its abstract methods mu
Abstract methods are methods without implementation. They are used to enforce implementation by subclasses.
Abstract methods are declared with the 'abstract' keyword and end with a semicolon instead of a method body.
They are used in abstract classes to enforce implementation by subclasses.
Subclasses must provide an implementation for all abstract methods or be declared as abstract themselves.
Abstract methods are useful ...
