Inheritance is a mechanism in OOP where a class inherits properties and behaviors from another class.

• Inheritance allows a class to reuse code from another class.

• Types of inheritance include single inheritance, multiple inheritance, multilevel inheritance, hierarchical inheritance, and hybrid inheritance.

• Example: Class B inheriting from Class A - B is a subclass of A.

ASP.NET Page Life Cycle is the series of events that occur from the time a page is requested to the time the page is fully rendered and sent to the client.

• Page Request: When a page is requested by a user, ASP.NET creates an instance of the page class.

• Page Initialization: The page's properties are set and controls on the page are initialized.

• Page Load: The page's controls are loaded with data and events are handled.

• Postback Event Handling: If the page is posted back, the event...read more

Abstract class is a class that cannot be instantiated and may contain abstract methods. Interface is a contract that defines methods that a class must implement.

• Abstract class can have abstract methods as well as concrete methods.

• Interface can only have method signatures, no method bodies.

• A class can implement multiple interfaces but can inherit from only one abstract class.

• Example: Abstract class - Animal with abstract method 'eat'. Interface - IShape with method signatures ...read more

A view is created from a model by using a view engine to render the model data into HTML markup.

• Use a view engine like Razor in ASP.NET to create views from models

• Pass the model data from the controller to the view using ViewBag or strongly-typed models

• Use HTML helpers to display model data in the view

ViewBag, ViewData, and TempData are used to pass data from controller to view in ASP.NET MVC.

• ViewBag is a dynamic property that allows you to pass data from controller to view.

• ViewData is a dictionary object that allows you to pass data from controller to view.

• TempData is a dictionary object that allows you to pass data from one controller action to another.

ActionResult and ViewResult are classes in ASP.NET MVC used to return responses to client requests.

• ActionResult is a base class for action results in ASP.NET MVC.

• ViewResult is a type of ActionResult that returns a view to the client.

• ViewResult inherits from ViewResultBase class.

• ActionResult can be used to return different types of responses like JSON, File, Redirect, etc.

• Example: return View();

Static keyword is used to declare a member that belongs to the class itself, rather than to instances of the class.

• Static keyword can be applied to variables, methods, properties, and constructors.

• Static members are accessed using the class name, not an instance of the class.

• Static variables retain their values for the entire duration of the program.

• Static methods can be called without creating an instance of the class.

• Example: public static int count = 0; // static variable

Sealed classes are classes that cannot be inherited or used as a base class.

• Sealed classes are used to restrict inheritance for security or optimization reasons.

• They are marked with the 'sealed' keyword.

• Example: 'sealed class MyClass {}'

ViewModel is a class that is responsible for preparing data to be displayed in a view.

• ViewModel separates the logic of data preparation from the view itself.

• It helps in keeping the views lightweight and focused on display.

• ViewModels are commonly used in MVVM (Model-View-ViewModel) architecture.

• Example: In an e-commerce website, a ProductViewModel may contain product details for display.

Calculate sum of digits in a given number

• Iterate through each digit in the number and add them together

• Use modulus operator to extract each digit

• Convert the number to a string to easily access individual digits

VPN is a secure way to connect to a private network over the internet. Private IP ranges are used to assign IP addresses within a network.

• VPN stands for Virtual Private Network

• It allows users to securely access a private network over the internet

• VPN encrypts the data transmitted over the network to ensure security

• Private IP ranges are used to assign IP addresses within a network

• There are three classes of private IP ranges: Class A (10.0.0.0 – 10.255.255.255), Class B (172.16....read more

Answering questions related to crimping, UTP fiber, VLANs, and the difference between hub and switch for a Network Engineer position.

• Crimping RJ45 connectors onto UTP cables is a common task for network engineers. Advantages include ease of installation and cost-effectiveness. Disadvantages include susceptibility to interference and limited distance.

• UTP fiber cables offer higher bandwidth and longer distances than UTP cables. Advantages include immunity to electromagnetic int...read more

Manual testing fundamentals, regression testing, regression vs retesting, V model, general logic testing

• Manual testing fundamentals include understanding test cases, test plans, and test execution without the use of automation tools

• Regression testing is the process of re-running test cases to ensure that new code changes have not adversely affected existing functionality

• Regression testing differs from retesting in that retesting focuses on verifying that a specific bug has be...read more

VLANs provide segmentation, security, and flexibility in network design.

• VLANs allow for logical segmentation of a network, separating traffic into different broadcast domains.

• This improves network performance and reduces congestion.

• VLANs also provide enhanced security by isolating sensitive data and restricting access to certain areas of the network.

• They also allow for flexibility in network design, making it easier to add, move, or change devices without disrupting the entir...read more

MPLS stands for Multiprotocol Label Switching.

• MPLS is a protocol used in computer networks to improve the speed and efficiency of data transmission.

• It operates at the network layer of the OSI model and is used to route packets based on labels instead of IP addresses.

• MPLS allows for the creation of virtual private networks (VPNs) and traffic engineering.

• It provides quality of service (QoS) capabilities by prioritizing certain types of traffic.

• Example: MPLS is commonly used by ...read more
