Study Notes
Computer Generations
- First Generation (1946-1958):
- Computers used vacuum tubes and magnetic drums for processing.
- Processing speed was 1,000 instructions per second.
- Size was limited to mainframes.
- Memory capacity was limited.
- Programming language was machine language (0s and 1s).
- Input used punch cards and paper tape.
- Output was printouts.
- Examples include UNIVAC (first commercial business computer), IBM 701.
- Operation was expensive and generated significant heat, leading to frequent malfunctions.
Second Generation (1959-1964)
- Major hardware features included transistors and magnetic core memory.
- Increased processing speed to 1 million instructions per second.
- Size remained mainframe.
- Increased memory capacity.
- Replaced vacuum tubes with transistors.
- Examples include UNIVAC 2, IBM 7030/7070/7090, 1400 series, RCA 501, Philco Transac S-200 and NCR 300 series.
- Transistors replaced 40 vacuum tubes with one. This resulted in smaller, faster, cheaper, and more energy-efficient computers.
- Still significant heat generation.
- Used assembly language (e.g., ADD, SUB, LD) for easier programming than machine language.
- Input and output still used punch cards and printouts.
- Introduced magnetic tape and discs for storage, also a reduction in heat generation compared to first generation.
Third Generation (1965-1970)
- Major hardware feature was the integrated circuit (IC) or chip.
- Processing speed increased to 10 million instructions per second.
- Size reduced to mini computers.
- Significantly increased memory capacity.
- Integrated circuits replaced transistors.
- Increased speed and efficiency.
- Transition to keyboard and monitor for input/output.
- Introduced operating systems enabling multiple applications.
- Increased accessibility and mass production.
- Development of the software industry.
- Reduction in size and cost, making computers accessible to a wider audience.
Fourth Generation (1971-Present)
- Major hardware features included 100,000 components on a chip.
- Processing speed increased to 100 million instructions per second.
- Sizes included mainframes, mini, and micro computers.
- Developed microprocessors, leading to microcomputers and supercomputers.
- Examples include Apple 2, TRS-80, IBM System 370/390, IBM PC XT/80, Motorola 6803.
- Development of personal computers (e.g., IBM's first home computer 1981, Apple Macintosh 1984).
- Networks and the internet emerged.
- Introduced the mouse and graphical user interfaces (GUIs).
- Large-scale integration (LSI) allowed thousands of components on a single chip.
- Emergence of user interfaces.
- Microcomputers and supercomputers became more common.
Fifth Generation (Present and Beyond)
- Goal is AI-powered devices responding to natural language input, learning, and self-organization.
- Applications include voice recognition.
- Uses of parallel processing and superconductors; quantum computation and nanotechnology will impact computers in the future.
- Moore's Law describes the exponential increase in circuit capacity.
- Development of artificial intelligence is the main goal.
