Study Notes
Generations of Computers
- 1st Generation (1944-1955): Utilized thermionic valves; large, heavy, and high power consumption; programming was slow and complex through hardwired methods.
- ENIAC: First electronic general-purpose calculator, built in 1946; weighed 33 tons, consumed 150 kW, and averaged 5000 operations per second.
- Hard Wired Programming: Early computers were programmed using numerous switches and manual cable connections.
Invention of Transistor
- Transistor (1947): Invented at Bell Labs by William Shockley, John Bardeen, and Walter Bartain; provided a smaller, more reliable, and cost-effective alternative to valves.
John Von Neumann
- Proposed a shift in programming paradigms by storing both programs and data in memory, eliminating manual rewiring.
Von Neumann Architecture
- Introduced key components such as a binary number system, sequentially addressed memory, separate arithmetic/logic unit, stored program concept, and a controller for instruction fetching and execution.
2nd Generation (1955-1964)
- Replaced valves with transistors, resulting in higher speeds, reduced size and weight, and lower manufacturing costs.
- Development of central processing units (CPUs), memory, programming languages, and input/output units; introduction of high-level programming languages led to significant software growth.
3rd Generation (1964-1971)
- Integrated Circuits (ICs) replaced previous components, leading to further size reductions and enhanced speed.
- Established large IC companies like Intel (1968) and AMD (1969); operating systems improved the efficiency and management of computing resources.
Key Developments in 3rd Generation
- Introduction of BASIC programming language in 1964, popularized for personal computers.
- DEC PDP-8, the first commercially successful microcomputer, launched in 1965.
4th Generation (1971-Present)
- Personal computers emerged, with IBM launching the PowerPC and Pentium introducing microprocessors; predominantly using large-scale and very-large-scale integrated circuits.
- Software advancements included more powerful operating systems like Unix and improved software development techniques, along with the introduction of fourth-generation languages (4GLs).
Summary of Computer Generations
- Evolution from large, power-hungry machines to compact, efficient, and affordable personal computers, showcasing rapid technological advancements and increased accessibility.
