Study Notes
Early History of Computers (Before 1800s)
- Abacus: An ancient calculating tool used for arithmetic operations.
- Slide Rule: A mechanical analog computing tool used for multiplication, division, roots, logarithms, and trigonometry.
- Blaise Pascal's Adding Machine: Invented in 1642, this machine was capable of adding and subtracting numbers.
- Leibniz Adding Machine: Invented in the early 1700s, this machine could perform addition, subtraction, multiplication, and division.
19th Century: Mechanical Computing
- Jacquard Loom (1800s): A weaving loom programmed using punched cards, which was key in inspiring the development of programmable computers.
- Babbage's Difference Engine (1820s): Designed by Charles Babbage, this mechanical computer was intended to calculate and print mathematical tables.
- Analytical Engine (1837): Also designed by Charles Babbage, this machine was considered the first general-purpose computer, though it was never built during his lifetime.
Early 20th Century: Towards Electronic Computing
- Colossus (1943): The world's first electronic computer, built in England to help decode German messages during World War II. It was based on vacuum tubes.
1946: The Birth of Modern Computing
- ENIAC (Electronic Numerical Integrator and Computer): Built by John Mauchly and J. Presper Eckert, ENIAC was the first general-purpose electronic digital computer.
- Von Neumann Architecture: A computer architecture developed by John von Neumann, proposing the use of a single memory space for instructions and data.
1950s: The Transistor Era
- The Transistor (1948): A semiconductor device that replaced vacuum tubes, leading to smaller, faster, and more reliable computers.
- Ferrite Core Memory: A type of magnetic memory technology used in second-generation computers.
1960s: The Rise of Mainframes
- Second Generation Computers: Characterized by the use of transistors and ferrite core memory.
- Large Mainframe Computers: Powerful computers used by large organizations for complex calculations and data processing.
1970s: The Integrated Circuit Revolution
- Integrated Circuits (ICs): Miniaturized electronic circuits containing thousands or even millions of transistors on a single chip.
- Microprocessor (1971): The first microprocessor, the Intel 4004, was a single chip that could perform all the functions of a computer's central processing unit (CPU).
- Digital Logic Families: Various types of integrated circuits used to build digital logic circuits (e.g., RTL, DTL, TTL, CMOS).
1980s: The Personal Computer Era
- Fourth Generation Computers: These used microprocessors and large-scale integration (LSI) and very-large-scale integration (VLSI) to create powerful and affordable computers.
- IBM PC (1981): The introduction of the IBM Personal Computer (PC) marked a turning point for home and business computing. It established the standards for personal computer hardware and software.
Computer Architectures
- Harvard Architecture: Features separate data paths for instructions and data.
- Von Neumann Architecture: Uses the same memory space for both instructions and data.
Computer Concepts
- Computer: A device that accepts input, processes data, stores data, and produces output.
- Central Processing Unit (CPU): The main processing unit in a computer responsible for executing instructions.
- Data: The symbols that a computer uses to represent facts and ideas.
- Input: The information that is conveyed to a computer.
- Memory: Stores data waiting to be processed.
- Output: The results produced by a computer.
- Storage: The area where data is retained on a permanent basis.
- Peripheral Devices: Expand a computer's input, output, and storage capabilities (e.g., printers, scanners).
- Software: Instructions that tell a computer how to perform a specific task.
- Hardware: Electronic and mechanical devices used for input, output, processing, and storing data.
Types of Computers
- Analog Computer: Processes continuous data (e.g., temperature, pressure).
- Digital Computer: Processes discrete data (e.g., numbers, characters).
- Hybrid Computer: Combines features of both analog and digital computers.
- Mainframes: Powerful computers used by large organizations.
- Supercomputers: Fastest computers in the world, used for high-performance computing.
- Servers: Computers that provide services to other computers on a network.
- Workstations: High-performance desktop computers used for specialized tasks.
- Personal Computers (PCs): General-purpose computers designed for individual use.
- Portable Computers: Laptops, notebooks, and tablets.
- Handheld Computers: PDAs and smartphones.
Microcomputers and Mini Computers
- Microcomputer: A type of computer built around a single microprocessor chip.
- Mini Computer: A type of computer that is larger and more powerful than a microcomputer, used by smaller organizations.
