Study Notes

Premechanical Period (3000 BCE - 1450 CE)

Humans started communicating using words and pictograms carved in rocks, later developing symbols to represent ideas and objects.
The development of alphabets from these symbols gave rise to our modern alphabet.
The invention of paper from papyrus plants led to the creation of permanent records and books.
The growth of books led to organized storage in libraries, which are considered the first data centers.
Humans started using numerical systems and the abacus, the first device to process information, is believed to have originated in China.

Mechanical Period (1450 - 1840)

The Mechanical period served as a bridge between the Premechanical period and the Electromechanical period.
Focus was on developing machines to enhance calculation speed.
Blaise Pascal invented the Pascaline, the first mechanical calculator.
Wilhelm Schickard also made significant contributions to the development of mechanical calculators.
Charles Babbage, known as the "Father of Computers", invented the Analytical Engine - the first programmable mechanical computer.

Electromechanical Period (1840 - 1940)

This period saw the use of electricity for information transmission.
The telegraph, which used dots, spaces, and dashes transmitted information over long distances via wired and wireless media.
William Cooke and Sir Charles Wheatstone invented the first working telegraph model which used magnetic needles to represent letters and numbers.
The telephone was invented enabling voice transmission over long distances.

Electronic Period (1940 - present)

Vacuum Tubes Period (1940 - 1956):
- Computers used vacuum tubes, making them large and inefficient.
- ENIAC (Electronic Numerical Integrator And Computer) was a large computer occupying 167 square meters, but with slower processing speeds compared to modern computers.
Transistors Period (1947 - 1964):
- The invention of the transistor (solid-state) revolutionized electronics, leading to smaller, faster, and more efficient computers.
- Transistors replaced vacuum tubes and became the foundation of all electronic devices.
Integrated Circuits (ICs) Period (1964 - 1971):
- Further miniaturization of computers enabled by integrated circuits.
Microprocessors Period (1971 - 1980):
- Microprocessors with thousands of ICs on a single chip, led to the development of personal computers (PCs).
Artificial Intelligence (AI) and Quantum Computing Period (1980 - present):
- This period focuses on AI and Quantum Computing, representing the most advanced phase of computer evolution.

World Wide Web (WWW)

Web 1.0 (Static Websites):
- Websites were static and non-interactive, with no user accounts or commenting capabilities.
- Advantages: lower costs, faster loading, cheaper hosting, and developer independence.
- Disadvantages: higher maintenance cost for frequent content changes, lack of user registration or advanced functionality, and dependence on developers.
Web 2.0 (Dynamic Websites):
- The current generation of the web focusing on collaboration and information sharing.
- Features: Folksonomy (tagging), rich user experience, user participation, software as a service (SaaS), and mass participation.
Web 3.0 (Semantic Web):
- Also called the Semantic Web, it aims to enable machines to understand and interpret human-generated content.
- It utilizes semantic technologies to understand user preferences, predict answers, and deliver tailored content.
- Examples include Apple's Siri.

Summary

Information technology has evolved over centuries, from basic forms of communication to advanced computing and artificial intelligence.
Each period witnessed breakthroughs in technology that led to smaller, faster, and more powerful computers.
The World Wide Web has evolved through three distinct stages, with each generation bringing new features and functionalities.
Web 3.0 promises to revolutionize the internet by empowering machines to understand and interpret human language, enabling personalized experiences and efficient information access.
