Multi-processing involves running multiple processes simultaneously, while multi-threading involves running multiple threads within a single process.

• Multi-processing allows multiple processes to run concurrently, each with its own memory space and resources.

• Multi-threading allows multiple threads to run within the same process, sharing the same memory space and resources.

• Multi-processing is typically used for CPU-bound tasks, while multi-threading is used for I/O-bound tasks....read more

Goods and Services Tax (GST) is a value-added tax levied on most goods and services sold for domestic consumption.

• GST is a consumption tax that is ultimately borne by the end consumer

• It is a single tax on the supply of goods and services, right from the manufacturer to the consumer

• GST eliminates the cascading effect of taxes, making the taxation system more efficient

• There are different GST rates for different goods and services, such as 5%, 12%, 18%, and 28%

• GST registration i...read more

Yes, we can declare the constructor private in a class.

• Yes, we can declare the constructor private to prevent instantiation of the class from outside.

• Private constructors are commonly used in singleton design pattern implementations.

• Example: private MySingleton() {}

Check if a linked list is a palindrome by comparing the values from both ends.

• Traverse the linked list to find the middle node using slow and fast pointers.

• Reverse the second half of the linked list.

• Compare the values of the first half with the reversed second half to check for palindrome.

• Example: 1->2->3->2->1 is a palindrome.

The ISO/OSI model consists of seven layers that define the different functions of a network communication system.

• Physical Layer: Deals with the physical connection between devices (e.g. cables, connectors)

• Data Link Layer: Manages the flow of data between devices on the same network (e.g. Ethernet)

• Network Layer: Handles routing and forwarding of data packets between different networks (e.g. IP)

• Transport Layer: Ensures reliable data transfer between end systems (e.g. TCP)

Object oriented programming language is a type of programming language that uses objects and classes to organize code.

• Uses objects and classes to structure code

• Encourages reusability and modularity

• Supports concepts like inheritance, encapsulation, and polymorphism

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.
