Study Notes
Introduction to Computer Science
- Computer science is a discipline encompassing algorithms, data, and applications.
- This overview covers fundamental concepts and themes.
- Algorithms are crucial; they define how tasks are performed.
- Programming involves creating programs based on algorithms.
- Software represents programs and their embedded algorithms.
- Hardware comprises the physical machinery.
The Role of Algorithms
- An algorithm is a sequence of steps, defining how tasks are performed.
- A program is an algorithm's representation.
- Programming is the process of developing a program.
- Software consists of programs plus their algorithms.
- Hardware is the physical computing machinery.
History of Algorithms
- The study of algorithms originated in mathematics.
- Examples include long division and the Euclidean Algorithm.
- Gödel's Incompleteness Theorem highlights limitations of algorithms. Some problems are unsolvable algorithmically.
History of Computing
- Early computing devices included the abacus and gear-based machines.
- Pioneers like Blaise Pascal, Wilhelm Leibniz, Charles Babbage, and Ada Lovelace contributed.
- Modern pioneers like Alan Turing and Margaret Hamilton were vital in advancing the field.
Data Storage
- Punched cards were historically used for data storage, notably in the Jacquard Loom (1801) and Babbage's Analytical Engine.
- Gear positions were another early method of storing data.
Early Computers
- Early computers leveraged mechanical relays and vacuum tubes.
- Key figures and milestones include: Stibitz at Bell Labs (1940), the Mark I (1944), the Atanasoff-Berry Computer (1937-1941), and the Colossus (1940s) and ENIAC (1940s).
###Transistors and Integrated Circuits
- Transistors emerged, leading to miniaturization and reduced power consumption.
- Integrated circuits (ICs) packed multiple transistors onto a single chip.
###Personal Computers
- Hobbyists built early personal computers.
- Apple Computer and IBM's PC introduction (1976 and 1981) were pivotal.
- PCs became a ubiquitous computing standard.
- Microsoft software became a leading choice for PCs.
End of the 20th Century
- The internet revolutionized communications and information access.
- Miniaturization of computing devices, including embedded systems and smartphones, further expanded the reach of computer technology.
###Outline of Study
- The course material will cover topics such as data storage, manipulation, operating systems, networking, and programming languages.
- Other topics include software engineering, data abstraction, computer graphics, artificial intelligence and computational theory.
Overarching Themes
- The book emphasizes the broad impact of computing technology in modern society, highlighting applications and their social consequences.
- The seven key components unify the scope of the subject; Algorithms, Abstraction, Creativity, Data, Programming, Internet, and Impact.
