Study Notes
Computer Definitions and Types
- A computer is an electronic device that processes data according to a set of instructions (a program). It can store, retrieve and process information, performing tasks ranging from simple calculations to complex operations.
- The first electronic computers were developed in the 20th century. Alan Turing, often called the "Father of Modern Computing," developed the concept of the Turing Machine in 1936.
- ENIAC (Electronic Numerical Integrator and Computer), developed in 1945 by John Presper Eckert and John Mauchly, was the first general-purpose programmable electronic computer.
Key Inventors and Innovations
- Key inventors include Charles Babbage (mechanical computer), Alan Turing (modern computing theory), and John Presper Eckert and John Mauchly (ENIAC). Intel was crucial in microprocessor development.
- Significant innovations include the Analytical Engine (1837), ENIAC (1945), the IBM PC (1981), the transistor (1947), and the microprocessor (1971).
Computer Examples
Desktop Computers
- Designed for use at a fixed location (homes and offices).
- Examples: Dell XPS, HP Pavilion.
Laptop Computers
- Portable computers with integrated screens, keyboards, and batteries, ideal for mobility.
- Examples: MacBook Air, Lenovo ThinkPad.
Palmtop/Handheld Computers
- Small enough to fit in the palm of your hand, used for tasks like note-taking and basic computing.
- Examples: Palm Pilot, early PDAs.
Tablets
- Touchscreen devices blending features of laptops and smartphones, used for browsing, media, and productivity.
- Example: iPad, Samsung Galaxy Tab.
Smartphones
