Study Notes
History of Computers
- The term "computer" originally referred to a job role filled by individuals, often women, performing computations manually.
- Early calculations were focused on mathematical tables, bomb trajectories, and rocketry.
Key Figures in the History of Computing
- John Napier: Invented logarithms, facilitating complex calculations with lookup tables.
- Blaise Pascal: Created the first calculator in 1645 for tax collection, capable of addition and subtraction through rotating dials.
- Gottfried Wilhelm von Leibnitz: Invented the "Stepped Reckoner" in 1674, a machine able to add, subtract, multiply, and divide.
- Joseph-Marie Jacquard: Developed the use of punched cards to control looms, influencing future data processing methods.
- Charles Babbage: Designed the "Difference Engine" and "Analytical Engine," foundational to modern computers; the Difference Engine was never completely built.
- Lady Augusta Ada Byron: A mathematician and Babbage's collaborator, recognized as the first computer programmer for her work on algorithms for Babbage’s machines.
- Alan Turing: Authored "On Computable Numbers," showing machines could process binary data for problem-solving.
- John Vincent Atanasoff: Created the ABC, the first digital computer, processing data in binary (1s and 0s).
- Howard Aiken: Developed the ASCC (Automatic Sequence Controlled Calculator) with IBM, using mechanical relays.
- Dr. Grace Murray Hopper: Contributed to the ASCC project, invented the COBOL programming language, and coined the term "debugging."
- Jack Kilby: Invented the first integrated circuit in 1959, making computers smaller and more efficient.
- Bill Gates: Became interested in programming at a young age, later co-founding Microsoft.
- Larry Page and Sergey Brin: Created Google, initially a search engine called "BackRub," and transformed it into a tech giant with numerous services and acquisitions.
Google's Development
- Google evolved from a small startup to one of the largest companies globally, expanding services like Gmail, Google Maps, and Google Books.
- Since 2010, Google has been acquiring a company per week, including YouTube and Android.
- As of 2019, Google's estimated valuation was $927 billion.
Microsoft Word Features
- Users can add and format text, insert various elements (pictures, tables, shapes), and save files efficiently to the cloud for collaboration.
Microsoft Excel Overview
- Used for organizing data, performing financial analysis, and various business functions like accounting, charting, programming, and task management.
- Consists of worksheets, each made of rows and columns, with features such as active cells, cell references, and a formula bar for data entry.
Types of Data in Excel
- Label: Text descriptions aligned left; non-calculative.
- Value: Numeric data aligned right; used in calculations.
- Formula: Equations or expressions that compute values based on data in cells.
