Study Notes
Computer Fundamentals
- A computer is an electronic device manipulating data according to instructions (programs).
- Data types include numbers, text, images, audio, and video.
- Computers process data, producing outputs like displayed text, printed documents, or audio signals.
- Computer operation relies on electrical circuits using binary (0 and 1) signals.
- Basic computer operations are input, processing, storage, and output.
- Input devices (keyboards, mice) allow data entry.
- Data manipulation (processing) follows instructions.
- Storage devices (e.g., hard drives, SSDs) retain data.
- Output devices (monitors, printers) display results.
- Computers span a range from personal computers to supercomputers, differing greatly in size, speed, and capability.
- Computers are crucial in modern society, influencing communication, entertainment, science, and industry.
- Sophisticated software controls computers and executes tasks.
- Fundamental computer components are the CPU (central processing unit), RAM (memory), storage devices, input devices, and output devices.
- The CPU manages instructions and calculations (the "brain").
- RAM holds active data and instructions.
- Storage holds data permanently.
- Modern devices (smartphones, tablets) function similarly, employing the same processing and storage principles.
- Computers utilize interconnected, complex circuits and pathways.
- Precise timing and synchronization are crucial for data manipulation.
- Computers have evolved considerably from larger, less powerful models to smaller, more capable devices, due to technological advancements such as component miniaturization and improved circuit design.
