Introduction to Computer and Programming Lec 01 Part 01 (Brief History of Computer)

Introduction

This tutorial provides an overview of the history of computers, highlighting key developments and innovations that have shaped the technology we know today. Understanding these milestones is essential for anyone interested in computer science and programming as they lay the foundation for modern computing.

Step 1: Explore the Abacus

• The abacus is one of the earliest known calculating tools, dating back to ancient times.
• It consists of a frame with rods, each holding beads that can be moved to perform arithmetic operations.
• Practical Tip: Familiarize yourself with basic arithmetic using an abacus to appreciate its simplicity and effectiveness.

Step 2: Learn about Napier's Bones

• Napier's Bones are a set of numbered rods that facilitate multiplication and division.
• Developed by John Napier in the early 17th century, this tool simplified complex calculations.
• Practical Advice: Try using a replica of Napier's Bones or online simulators to practice multiplication.

Step 3: Understand the Slide Rule

• The slide rule, invented in the 17th century, is an analog device used for calculation.
• It uses logarithmic scales to allow rapid multiplication, division, and function evaluation.
• Common Pitfall: Remember that the slide rule requires understanding of logarithmic principles; ensure you grasp these concepts before using it.

Step 4: Discover Schickard's Calculating Clock

• Created by Wilhelm Schickard in the early 17th century, this device is considered one of the first mechanical calculators.
• It could perform addition and subtraction automatically, marking a significant advancement in computing technology.
• Practical Tip: Research more about Schickard's inventions and how they influenced later developments in computing devices.

Conclusion

The history of computers is rich with innovation and creativity, from the simplicity of the abacus to the mechanical wonders of Schickard's calculating clock. By exploring these early tools, you gain insight into the evolution of technology that underpins modern computing. Next steps could include delving deeper into the history of computer programming or exploring the development of electronic computers.
