An ideal diode is a theoretical diode that exhibits zero voltage drop when forward biased and infinite resistance when reverse biased.
An ideal diode acts as a perfect conductor when forward biased.
It allows current to flow in one direction with zero voltage drop.
When reverse biased, it acts as an open circuit with infinite resistance.
The input-output characteristic curve of an ideal diode is a vertical line at zero vol...
Program to compute factorial of a number using recursion
Define a function that takes a number as input
Check if the number is 0 or 1, return 1 if true
Else, call the function recursively with n-1 as input and multiply with n
Return the result
Example: factorial(5) = 5 * factorial(4) = 5 * 4 * factorial(3) = 5 * 4 * 3 * factorial(2) = 5 * 4 * 3 * 2 * factorial(1) = 5 * 4 * 3 * 2 * 1 = 120

The OSI model has 7 layers that define how data is transmitted over a network.
Layer 1: Physical - deals with the physical connection of devices
Layer 2: Data Link - responsible for error-free transfer of data between devices
Layer 3: Network - handles routing of data between different networks
Layer 4: Transport - ensures reliable delivery of data between applications
Layer 5: Session - establishes and manages connections ...
Session layer manages and controls the connections between applications.
Establishes, maintains and terminates sessions between applications
Synchronizes data exchange between applications
Manages session checkpoints and recovery
Examples: Telnet, FTP, SMTP
A zener diode is a type of diode that allows current to flow in the reverse direction when a certain voltage is reached.
Zener diodes are commonly used as voltage regulators.
They have a sharp breakdown voltage, which makes them useful for stabilizing voltage in electronic circuits.
Zener diodes are often used in power supplies, voltage references, and surge protectors.
They are also used in noise reduction circuits and as...

Program to print first 10 natural numbers on the screen
Declare a variable i and initialize it to 1
Use a loop to print i and increment it until i reaches 10
An IP address is a unique numerical identifier assigned to every device connected to the internet.
IP stands for Internet Protocol
It consists of four sets of numbers separated by dots
Each set can range from 0 to 255
Example: 192.168.1.1 is an IP address
IPv4 and IPv6 are the two versions of IP addresses

Generate a star pattern using a desired language.
Use nested loops to print the desired number of rows and columns.
In each iteration, print a '*' character to form the pattern.
Adjust the loop conditions and print statements to create different patterns.
Consider using variables to control the number of rows and columns.
Experiment with different loop structures to create more complex patterns.

Array is a collection of elements of same data type. Linked list is a data structure consisting of a group of nodes.
Arrays are used to store and access a fixed number of elements in memory.
Linked lists are used to store and access a variable number of elements in memory.
Arrays have a fixed size, while linked lists can grow or shrink dynamically.
Arrays are accessed using an index, while linked lists are accessed using p...
OOPs concepts are the fundamental principles of object-oriented programming.
Abstraction: Hiding implementation details and showing only necessary information.
Encapsulation: Binding data and functions together in a single unit.
Inheritance: Acquiring properties and behavior of a parent class by a child class.
Polymorphism: Ability of an object to take many forms.
Example: A car is an object that has properties like color, ...
