Computer Networks: Definition and OSI Model’s Open Nature

A computer network is a collection of interconnected computers and other hardware devices that are linked together to share resources, exchange data, and communicate. These networks can be connected via wired (e.g., Ethernet) or wireless (e.g., Wi-Fi) means. The main purpose of a computer network is to enable devices to work together, share files, access the internet, and use shared applications or hardware like printers.

Why the OSI Model

AWT Controls: Label, Button, TextField

AWT (Abstract Window Toolkit) is Java’s GUI toolkit used to create graphical user interfaces. It provides basic UI components like buttons, labels, text fields, etc.

1. Label:

  • A Label is a non-editable text element used to display a single line of read-only text.
  • It does not accept user input.
  • Mainly used to identify other GUI components.

2. Button:

Java File I/O and Collections Framework Essentials

Java File Operations with RandomAccessFile

The RandomAccessFile class in Java is part of the java.io package and provides functionality for reading from and writing to a file at any specified position. Unlike sequential input/output streams, RandomAccessFile allows non-sequential access to file contents, making it suitable for tasks like updating specific parts of a file or working with structured data records.

RandomAccessFile Example: Reading, Writing, and Appending

Python Image Processing: Core Techniques with OpenCV

This document demonstrates various fundamental image processing techniques using Python libraries such as OpenCV, NumPy, and Matplotlib. Each section provides a code example and a brief explanation of the concept.

Image Transformations

Image transformations involve altering the spatial arrangement of pixels within an image. This section covers common transformations like rotation, scaling, and translation.

Rotation (45° Around Center)

Rotation transforms an image by turning it around a central point.
