Logic Gates are the basic building blocks of any digital system. They perform logical operations on one or more binary inputs to produce a single binary output.
Here is a breakdown of the common logic gates, including their symbols, Boolean expressions, and truth tables.
1. Basic Logic Gates
These three gates are the fundamental operations from which all other logical functions are derived.
| Gate | Symbol | Boolean Expression | Output Condition | Truth Table (A, B \rightarrow
Y) |

Game Engine Architecture, Rendering, and Python Libraries
Game Engine Architecture Fundamentals
A game engine is software that helps create and run games by managing graphics, audio, input, and logic.
Core Components of a Game Engine
- Graphics Engine: Renders images and animations using the GPU.
- Audio Engine: Manages music and sound effects.
- Input Module: Handles input from the keyboard, mouse, and gamepads.
- Device APIs/DLLs: Connects the engine to hardware.
- Game Logic & Main Loop: Controls gameplay flow and timing.

ER Diagram Conversion to Relational Schema
The objective is to convert specified Entity-Relationship (ER) diagrams into a functional relational schema, defining appropriate primary and foreign keys.
A. University Database Relational Schema Mapping
Assuming the ER diagram for the University includes the following entities and relationships (based on typical university data models):
Entities Defined:
- Student: (sid, sname, age, major)
- Course: (cid, cname, credits)
- Professor: (pid, pname, department)

Java Fundamentals: Structure, Data Types, and Casting
The basic structure of a Java program is based on the concept of classes. Every executable Java program must contain at least one class definition.
Essential Structure of a Java Program
A typical Java application follows this hierarchical structure:
Package Statement (Optional)
The very first statement in a Java source file (if present) is the package statement. It organizes classes into logical groups, preventing naming conflicts.
- Syntax:
package package_name; - Example:
package com.mycompany.app;
- Syntax:
Import

Common Types of Active Network Attacks
The various types of active attacks are described as follows:
- Masquerade Attack: This occurs when an unauthorized entity pretends to be a legitimate user or system to gain access to resources. For example, an attacker sends a message to a user pretending to be someone else, and the recipient is unaware of the impersonation. A common scenario involves “Darth” sending a message to Alice while pretending to be Bob.
- Replay Attack: This involves the unauthorized capture

Example: Simple HTTP Request (Browser to Server)
GET /index.html HTTP/1.1
Host: www.example.com
User-Agent: Chrome/122.0
Accept: text/htmlThis is the real request your browser sends to the server.
