Study Notes
Introduction to Information Technology
- Information Technology (IT) encompasses all digital forms of information, differing from traditional paper communication.
- The evolution of communication highlights significant advancements from slow correspondence to instant messaging.
Emergence of Information Society
- The millennial generation plays a crucial role in the rise of an information-centric society.
- Instant notifications and digital interactions have transformed how individuals communicate and share content globally.
Historical Timeline of Computer Development
- The inception of IT can be traced back to WWII collaborations between military and industry for electronics development.
- Major technological advancements occurred from the 1940s to the 1950s, leading to the creation of four generations of computers:
- First Generation: Vacuum tubes.
- Second Generation: Transistors.
- Third Generation: Integrated circuits.
- Fourth Generation: Microprocessors on single chips.
Key Historical Milestones
- Abacus (c. 3000 BCE): Early computation tool used in ancient civilizations.
- Mechanical Calculators (17th-19th centuries):
- Pascaline (1642): Designed by Blaise Pascal for basic arithmetic.
- Leibniz Wheel (1673): An improvement on Pascal’s design.
- Analytical Engine (1837): Charles Babbage's concept for a general-purpose computer that wasn't completed but laid foundational ideas.
Advancements in Data Processing
- Punch Card Systems (1890s): Innovated by Herman Hollerith; utilized for efficient census data processing.
- Electromechanical Computers (1930s-1940s):
- Zuse Z3 (1941): First programmable computer by Konrad Zuse.
- Colossus (1943): Deployed by British forces for code-breaking during WWII.
- ENIAC (1945): The first general-purpose electronic digital computer, marking a transition in computing capabilities.
Technological Breakthroughs
- Transistor (1947): Developed by Bell Labs, replacing vacuum tubes and enhancing reliability and size efficiency.
- Mainframe Era (1950s-1960s): Dominated by IBM, exemplified by machines like IBM 704 for large-scale operations.
- Integrated Circuits (1958): Pioneered by Jack Kilby and Robert Noyce, leading to modern microchip technology.
- Personal Computers (1970s-1980s):
- Altair 8800 (1975): Often credited as the first personal computer, influencing the software and personal computing boom.
