Study Notes
Basic Computing Concepts
- A computer is an electronic device that takes input, processes it based on instructions, and outputs information.
- Input-Process-Output (IPO) system.
Data Types
- Data : Raw facts (e.g., 55, Malik).
- Types: Numeric (0-9), Alphabetic (letters), Alphanumeric (numbers, letters, special characters).
Information
- Data transformed into meaningful form.
- Transformation process: arithmetic (addition, subtraction, multiplication, division), logical comparison, character manipulation.
- Logical comparison: evaluating data relationships (greater than, equal to, less than).
- Output: reports (printed or displayed).
History of Computing
- Early counting: fingers, sticks, pebbles, ground marks.
- Abacus: early device for counting (still used today).
- Digital instrument using beads, sliding on wires.
- Divided into zones (upper, lower), using beads to represent values.
Blaise Pascal
- Scientist and philosopher.
- Invented Pascaline (mechanical calculator) in 1640s.
- Machine for calculating taxes.
- Small box with dials to represent digits, linked to carry-over mechanism for addition/subtraction.
Joseph Marie Jacquard
- Invented a power loom using punched cards for automated weaving patterns.
- Punched cards: descendants still used to store information.
Charles Babbage
- Designed the difference engine and an analytical engine.
- Wanted a programmable machine incorporating complete arithmetic units, store, input, and output.
- Ideas foreshadowed modern computers.
- Unable to complete devices due to technology limitations.
- Invented modern postal system, cow catchers, the ophthalmoscope.
Augusta Ada Byron
- Poet's daughter.
- Early programmer, wrote "Notes" detailing instructions for Babbage's Analytical Engine.
- First computer programmer.
- Developed the concept of subroutines/loops.
Herman Hollerith
- Developed punched-card tabulating machines to process the census.
- His company merged with other companies to become IBM.
- Designed punch card machines using holes, tabulators, counters, sorting boxes.
- The processing speed of the 1890 census was faster.
- Employed his machine across various other countries.
John Von Neumann
- Mathematician.
- Developed the concept of stored-program computer where instructions and data are stored in the computer's memory; this facilitated operation speed and made computers more versatile.
Howard Aiken
- Harvard Mark I computer: first programmable electronic computer in the US.
- Used relays, switches, and mechanical components rather than electronic ones.
- Developed at Harvard and IBM.
Grace Hopper
- Found the first "computer bug" (dead moth).
- Created first high-level language, "Flow-Matic".
- Compiler created for translating high-level language into machine code, making it more accessible to people who don't understand code.
Bill Gates
- Co-founded Microsoft and developed MS-DOS.
- The development was prompted by the adoption of Intel microprocessors in personal computers.
Philip Emeagwali
- Invented a supercomputer that processed data very rapidly, which was used to help determine the recovery rate of oils.
- Used 65,000 separate computer processors, which was revolutionary for that time; it made the supercomputer possible at the time.
