History of Computing: Early Computing Periods
- Tally Sticks: Ancient memory aids used for recording numbers, quantities, and messages
- Abacus: A mechanical device for mathematical calculations, invented in Babylonia in 2400 BC, and used in China around 500 BC to perform basic arithmetic
- Napier's Bones: Invented by John Napier in 1614, they facilitated multiplication, division, and root calculations through manipulation of rods on a specially designed board
- Slide Rule: Invented by William Oughtred in 1622, based on Napier's logarithmic principles, it was primarily used for multiplication, division, root calculations, logarithms, and trigonometry, but not addition or subtraction
- Pascaline: Invented by Blaise Pascal in 1642, limited to addition and subtraction, it was considered too expensive
- Stepped Reckoner: Invented by Gottfried Wilhelm Leibniz in 1672, it was capable of performing automated addition, subtraction, multiplication, and division
- Jacquard Loom: Invented by Joseph-Marie Jacquard in 1881, this automatic loom was controlled by punched cards
- Arithmometer: Invented by Thomas de Colmar in 1820, this machine was the first reliable, commercially successful, and mass-produced calculating device capable of performing the four basic arithmetic functions
- Difference Engine and Analytical Engine: Invented by Charles Babbage in 1822 and 1834, respectively, these were automatic mechanical calculators designed to tabulate polynomial functions and were considered the first mechanical computers.
- First Computer Programmer: In 1840, Augusta Ada Byron suggested Babbage use the binary system and wrote programs for the Analytical Engine
- Scheutzian Calculation Engine: Invented by Per Georg Scheutz in 1843, based on Babbage's Difference Engine, it was the first printing calculator
- Tabulating Machine: Invented by Herman Hollerith in 1890, it aided in information summarization and accounting.
Evolution of Computing: The First Computers
- Earliest calculations were performed by human "computers" trained in mathematics
- The first recorded use of the term "computer" was in 1613, referring to the person performing calculations
The Rise of Writing and Information Storage
- Writing originated with marks in wet clay, evolving to paper made from papyrus
- The Chinese were prominent in developing paper from rags
- The invention of paper led to the development of books and libraries for permanent storage
- Egyptian scrolls provided a common method for recording information
- Early groups bound paper together into book-like structures
Early Number Systems and The First Calculator
- The first 1-9 number system was created around 100 AD by individuals from India
- The number 0 was invented in 875 AD
- The abacus was the first calculator and a popular information processor.
The Mechanical Age: From 1450 to 1840
- This era marked connections between modern technology and its ancestors
- Technologies like the slide rule and Blaise Pascal's Pascaline mechanical computer were invented during this time.
- Charles Babbage developed the Difference Engine, a mechanical calculator for tabulating polynomial equations using finite differences.
Electromechanical Age: Transistors and Integrated Circuits
- The third generation of computers replaced vacuum tubes with transistors and integrated circuits, leading to smaller, faster, more efficient devices
- Magnetic tape became a crucial component of computers and magnetic core technology was replaced with metal oxide semiconductors
- An operational system and the programming language BASIC emerged during this era.
The Fourth Generation: Microprocessors, Personal Computers, and Networks
- The microprocessor, integrating thousands of integrated circuits on a single chip, was key for the fourth generation
- This era saw the development of personal computers (e.g., the Apple II) and graphical user interfaces (GUIs)
- Networks and the internet evolved from connecting these small but powerful computers.
Fifth Generation: Artificial Intelligence and Beyond
- This generation, still under development, focuses on artificial intelligence (AI)
- Parallel processing and superconductors are being used to make AI a reality
- The goal is to develop devices that respond to natural language input and possess learning and self-organization capabilities
- Applications like voice recognition are already being used.
Generations of Computers
- First Generation (1946-1958): Used vacuum tubes for circuitry and magnetic drums for memory, were large, expensive, and generated a lot of heat. Only machine language was supported for programming, and they could only solve one problem at a time. Input was through punched cards and paper tape, and output was displayed on printouts. Examples: ENIAC, EDSAC, UNIVAC I, II, and 1101
- Second Generation (1959-1964): Transistors replaced vacuum tubes, making computers smaller, faster, cheaper, more energy-efficient, and reliable. However, heat generation still posed problems. Assembly languages were introduced for programming, and instructions began to be stored in memory (magnetic core technology replacing magnetic drums). Input was through punched cards, and output was through printouts. Examples: UNIVAC III, RCA 501, Philco Transact S-2000, NCR 300 series, IBM 7030 Stretch, IBM 7070, 7080, 7090 series
- Third Generation (1965-1970): Integrated circuits (transistors on silicon chips) were developed, significantly increasing speed and efficiency while reducing size and cost. Instructions were executed in billionths of a second.
- Fourth Generation (1971-Present): Microprocessors (thousands of integrated circuits on a single chip) brought about a revolution. Computers became more powerful and could be linked into networks. The internet originated from this interconnection of computers. The development of GUIs and the mouse, along with handheld devices, also occured in this era.
- Fifth Generation (Present-Future): Built upon artificial intelligence (AI). Parallel processing and superconductors are being utilized to advance AI. The aim is to create devices that can understand natural language, learn, and self-organize. Examples of existing applications include voice recognition.
