Document Object Model (DOM) is a programming interface for web documents.

• DOM is a tree-like structure that represents the HTML or XML document.

• It allows developers to manipulate the content and structure of a web page using programming languages like JavaScript.

• DOM provides a set of methods and properties to access and modify the elements of a web page.

• Changes made to the DOM are reflected in the web page in real-time.

• DOM can be used to create dynamic web pages and web applic...read more

ACID property ensures database transactions are reliable and consistent.

• ACID stands for Atomicity, Consistency, Isolation, and Durability.

• Atomicity ensures that a transaction is treated as a single, indivisible unit.

• Consistency ensures that a transaction brings the database from one valid state to another.

• Isolation ensures that concurrent transactions do not interfere with each other.

• Durability ensures that once a transaction is committed, it will remain so even in the face o...read more

Normalization is the process of organizing data in a database to reduce redundancy and dependency.

• Normalization helps to eliminate data redundancy and inconsistencies.

• It involves breaking down a table into smaller tables and defining relationships between them.

• Normalization is achieved through a series of normal forms, such as first normal form (1NF), second normal form (2NF), and so on.

• Normalization ensures data consistency and improves database performance.

• Example: A custom...read more

Multilevel inheritance is a concept in object-oriented programming where a class inherits properties and methods from another class, which in turn inherits from another class.

• Multilevel inheritance involves creating a hierarchy of classes, where each class inherits from the class above it.

• The derived class inherits the properties and methods of the base class, and can also add its own unique properties and methods.

• This type of inheritance allows for code reusability and promo...read more

Interface defines only method signatures while abstract class can have method implementations.

• Interface cannot have constructors while abstract class can.

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

• Abstract class can have non-abstract methods while interface cannot.

• Abstract class can have instance variables while interface cannot.

• Example of interface: Runnable interface in Java.

• Example of abstract class: HttpServlet class in Java Servlet ...read more

The data structure used to reverse an array is a stack.

• A stack data structure can be used to reverse an array by pushing each element onto the stack and then popping them off in reverse order.

• Example: If we have an array of strings ['apple', 'banana', 'cherry'], we can reverse it using a stack to get ['cherry', 'banana', 'apple'].

To upload files in a Node.js application, you can use the 'multer' middleware package.

• Install 'multer' package using npm

• Set up multer middleware in your Node.js application

• Create a route in your application to handle file uploads

• Use 'multer' to process and save uploaded files to a specified destination

Event Loop in NodeJS manages asynchronous operations by executing callback functions when certain events occur.

• Event Loop continuously checks the Call Stack and Callback Queue to see if there are any functions that need to be executed.

• If the Call Stack is empty, Event Loop will move functions from the Callback Queue to the Call Stack for execution.

• Event Loop allows NodeJS to handle multiple requests concurrently without blocking the execution of other code.

• Example: setTimeout...read more

justify-content is a CSS property that defines how flex items are aligned along the main axis of a flex container.

• It is used in CSS flexbox layout.

• It controls the alignment of flex items horizontally.

• Possible values include: flex-start, flex-end, center, space-between, space-around, and space-evenly.

• Default value is flex-start.

Use CSS property 'caret-color' to change cursor color.

• Use 'caret-color' property in CSS to change cursor color

• Specify the color value for 'caret-color' property

• Example: input { caret-color: red; }

display: flex is a CSS property that allows flexible and responsive layout design.

• It is used to create a flexible box layout model.

• Elements inside a flex container can be easily aligned and positioned.

• Flexbox provides powerful features for distributing space and controlling the size of items.

• It simplifies the process of creating responsive designs.

• Example: .container { display: flex; }

Object fit is a CSS property that specifies how an image or video should be resized and positioned within its container.

• Object fit can be set to values like 'contain' or 'cover' to control the scaling and positioning of the content.

• The 'contain' value scales the content to fit within the container while preserving its aspect ratio.

• The 'cover' value scales the content to cover the entire container, potentially cropping parts of it.

• Other values like 'fill', 'none', 'scale-down'...read more

Agile testing methods involve continuous testing throughout the development process to ensure quality and timely delivery.

• Testing is integrated into the development process

• Testing is done in short iterations or sprints

• Testing is focused on customer requirements

• Test automation is used to speed up testing

• Collaboration between developers and testers is essential

Using recursion to print numbers from 1 to 100 without a loop

• Create a recursive function that takes a number as input and prints it

• Call the function with 1 as the initial input and increment the input by 1 in each recursive call

• Stop the recursion when the input reaches 100

States play a crucial role in the functioning of a country's government and administration.

• States are administrative divisions within a country.

• They have their own governments and are responsible for managing their own affairs.

• States play a key role in the federal system of government, where power is shared between the central government and the states.

• They are responsible for implementing policies and programs at the local level.

• Examples of states include California, Texas, ...read more

2NF eliminates partial dependencies, while 3NF eliminates transitive dependencies.

• 2NF eliminates partial dependencies by ensuring all non-key attributes are fully functionally dependent on the primary key.

• 3NF eliminates transitive dependencies by ensuring that non-key attributes are not dependent on other non-key attributes.

• Example: In a table with columns A, B, and C where A is the primary key, if B depends on A and C depends on B, it violates 3NF.

• Example: In a table with co...read more

Delete removes rows from a table while truncate removes all rows from a table.

• Delete is a DML command while truncate is a DDL command.

• Delete operation can be rolled back while truncate operation cannot be rolled back.

• Delete operation fires triggers on each row deletion while truncate operation does not fire triggers.

Traits are reusable code blocks that can be mixed into classes, while interfaces define a contract that a class must follow.

• Traits can be used to add methods to a class without inheritance

• Interfaces define a set of methods that a class must implement

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

• Traits promote code reusability and reduce code duplication
