Study Notes
Introduction to Computers
- Digital and analog computers differ in how they represent data. Digital computers use discrete values (0s and 1s), while analog computers use continuous values.
- Computers are characterized by speed, accuracy, diligence, storage capability, and versatility.
- Computers are used in various aspects of daily life, including ticket reservations, bill payments, financial transactions, data processing, and weather forecasting.
Computer History
- Early calculating devices include the abacus, Napier's bones, slide rule, Pascal's adding machine, and Leibniz's calculating machine.
- Jacquard's punched cards used holes to control a loom, foreshadowing the use of binary code in computers.
Computer Generations
- First Generation (1940-1956): Used vacuum tubes.
- Second Generation (1956-1963): Used transistors.
- Third Generation (1964-1971): Employed integrated circuits.
- Fourth Generation (1971-Present): Utilized microprocessors.
- Fifth Generation (Present and Next): Based on artificial intelligence.
Computer Classification
- Microcomputers: Personal computers (PCs), laptops, notebooks, tablets, smartphones.
- Minicomputers: Multi-user systems with medium-range processing and storage capabilities.
- Mainframe Computers: Designed for large-scale data processing and multiple users concurrently.
- Supercomputers: High-performance computers for complex calculations and simulations involving large datasets.
Computer Components
- Hardware: The physical components of a computer (e.g., keyboard, monitor, CPU, memory, storage devices).
- Software: The set of instructions that tell the computer what to do (e.g., operating systems, applications).
- Data: Raw facts and figures that are processed by the computer.
- Users: Individuals who interact with and operate the computer.
Input-Process-Output Concept
- Computers accept input, process it, and produce output.
- This is fundamental to how computers operate.
