  - Web pages ko automatically visit karke unka content gather karna.

- **Indexing:** 
  - Web pages ke content, metadata, aur keywords ko structured format mein store karna.

- **Query Processing:**
  - User queries ko analyze karna aur relevant indexed pages ko retrieve karna.

- **Ranking:** 
  - Retrieved pages ko relevance aur quality ke basis pe rank karna.

- **Search Results:** 
  - Search queries ke basis pe results generate karna jisme text snippets, images, and links included hote hain.

- **Autocomplete:** 
  - Search suggestions provide karna jab user query type karta hai.

- **Personalization:** 
  - User’s search history aur preferences ke basis pe personalized results provide karna.

### **Browser Features:**

- **Rendering:**
  - Web pages ke HTML, CSS, aur JavaScript ko process karke visual representation display karna.

- **Hyperlink Navigation:**
  - Hyperlinks pe click karne par web pages load karna aur navigate karna.

- **Tabs and Windows:**
  - Multiple web pages ko ek hi browser session mein alag tabs aur windows mein open karna.

- **Bookmarks:**
  - Frequently visited web pages ko save karna aur easily access karna.

- **Extensions and Add-ons:**
  - Additional features aur functionalities ko install karna (e.g., ad blockers, password managers).

- **Privacy and Security:**
  - Browsing data ko manage karna, secure connections (HTTPS) provide karna, aur privacy settings allow karna.

- **History and Cache:**
  - Browsing history ko record karna aur frequently visited pages ko cache mein store karna for faster access.

- **Download Management:**
  - Files ko download karna aur manage karna (e.g., progress tracking, file location).

### **Summary:**

- **Search Engine:** Web pages ko crawl aur index karta hai, queries process karta hai, aur relevant search results provide karta hai.
- **Browser:** Web pages ko render karta hai, hyperlinks ke through navigate karta hai, aur user interaction features provide karta hai.

Collection Framework of Java

 The Java Collection Framework provides a set of interfaces and classes that allow you to work with groups of objects in a standardized way. The framework is divided into several interfaces and classes, including `List`, `Set`, `Queue`, `Map`, and their various implementations. Here’s an overview of the main interfaces and classes in the Java Collection Framework, along with examples for each: ### 1. **List Interface** - **Characteristics**: Ordered collection (sequence) that allows duplicates. Elements can be accessed by their index. #### Implementations: - **ArrayList**: Resizable array implementation of the `List` interface. - **LinkedList**: Doubly-linked list implementation of the `List` and `Deque` interfaces. - **Vector**: Synchronized, resizable array implementation. - **Stack**: A subclass of `Vector` that represents a last-in, first-out (LIFO) stack. #### Example: ```java import java.util.ArrayList; import java.util.LinkedList; import java.util.Vector; import java.util.St...

What is DBMS ?

 ### DBMS (Database Management System) A **Database Management System (DBMS)** is software that interacts with the user, applications, and the database itself to capture and analyze data. A DBMS allows users to create, read, update, and delete data in a database. It ensures data integrity, security, and concurrency while providing support for data manipulation and retrieval. #### Types of DBMS 1. **Hierarchical DBMS**:    - Data is organized in a tree-like structure.    - Example: IBM Information Management System (IMS). 2. **Network DBMS**:    - Data is organized in a graph, allowing many-to-many relationships.    - Example: Integrated Data Store (IDS). 3. **Relational DBMS (RDBMS)**:    - Data is stored in tables (relations) and can be linked based on data common to each.    - Examples: MySQL, PostgreSQL, Oracle, Microsoft SQL Server. 4. **Object-oriented DBMS (OODBMS)**:    - Data is stored in objects, similar...

Compiler vs Interpreter vs JIT Compiler

 Interpreter : Interpreter is a program which translates code into the intermediate code(Byte code) and then  executes line by line at runtime . That's why Speed is low. * Initial Phase: Source code is executed directly. * Runtime Monitoring: Code is interpreted line by line or statement by statement.   * Execution Phase: Execution happens in real-time without a separate compilation step. * Advantages: Flexibility, immediate feedback. Compiler :  Compiler converts code into machine code before program runs.  * Initial Phase: Source code is compiled into machine code or intermediate form. * Compilation Phase: Entire program is compiled before execution starts. * Execution Phase: Executable or machine code is run directly by the CPU. * Advantages: Fast execution, extensive optimizations. JIT Compiler :   * Initial Phase: Source code is compiled to bytecode. * Runtime Monitoring: JIT compiler detects hot spots during runtime. * Co...
