Programming Paradigms: A Comprehensive Overview
Programming Paradigms
Introduction
A paradigm is a fundamental model or scheme that organizes our views regarding a particular topic. Programming paradigms represent a particular approach or philosophy for building software. They set limits for problem-solving and influence the development of new solutions.
Common Paradigms
- Imperative: The most common paradigm, focusing on program state and statements that change the state. Examples include C, Pascal, and COBOL.
- Object-Oriented: Organizes programs
Programming Paradigms: Imperative, OOP, Visual, Structured & More
Programming Paradigms
Imperative Programming
Imperative languages are based on commands that instruct the computer to perform actions, organize, or modify values in memory. These commands are typically executed sequentially.
Object-Oriented Programming (OOP)
OOP is a programming style that uses objects as fundamental building blocks. These objects encapsulate data (attributes) and functions (methods) that operate on that data, simulating real-world entities. OOP is considered a fifth-generation language.

The Limitations of Physical File Management
Traditional physical file management methods are often insufficient for managing organizational information due to several drawbacks:
- Space Consumption: Physical files occupy significant storage space.
- Slow Search: Searching through physical files can be a slow and tedious process.
- Complex Updates: Updating and optimizing physical files is complicated.
- Data Scatter: Files can be scattered across different departments,

Exception Handling
Exception handling manages errors during program execution. Here’s how it works:
Key Concepts
- Exception: An error disrupting normal program flow.
- Try Block: Code that might throw an exception.
- Catch Block: Handles exceptions thrown in the try block.
- Finally Block: Runs after try and catch, regardless of exceptions.
- Throwing Exceptions: Explicitly signaling errors.
String Handling
String handling manipulates and processes strings. Here’s an overview:
Common String Operations
- Creation: Declaring
Evolution of Operating Systems
History
Zero Generation (Late 1940s)
The first computer systems did not have operating systems. Users had full access to the machine language. All instructions were coded by hand.
First Generation (Late 1950s) – Vacuum Tubes and Plug-in Boards
At this time, there were no operating systems. The use of vacuum tube technology resulted in enormous machines. Users had to create all programs in binary code, and the machines were very expensive.
Early First Generation
The operating systems of the 1950s were
