Study Notes
Data Basics
- Bit: The smallest unit of data in a computer, with a binary value of either 0 or 1.
- Byte: A data unit consisting of eight bits, often representing a single character like a letter or number.
- Binary: A numbering system using only two digits, 0 and 1.
Programming Concepts
- Algorithm: A clear step-by-step process for completing a task or solving a problem.
- Program: A series of instructions, written in a computer language, for performing tasks or solving problems.
Snap! Programming Components
- Blocks: Puzzle-piece shapes used for coding in Snap!.
- Scripts: Connect various blocks to perform specific tasks.
- Sprites: Objects in Snap! that execute functions via scripts.
- Stage: The project background that responds to scripting.
Debugging and Errors
- Logic Error: A flaw in the algorithm or program leading to incorrect or unexpected behavior.
- Tracing: Manually simulating code execution to ensure program correctness.
- Debugging: The process of finding and fixing errors in software or hardware.
Data Representation and Errors
- ASCII: A standard character encoding system for electronic communication.
- Overflow Error: Occurs when data exceeds the storage capacity of its field.
- Roundoff Error: Arises from limitations in representing real numbers in computer calculations.
- Underflow Error: Happens when a mathematical operation produces a number too small for storage.
Pixel and Color Representation
- Pixel: A small illumination area on a display, crucial for image composition.
- RGB: Color model using red, green, and blue light to create various colors digitally.
Compression Techniques
- Heuristic: An approach to problem-solving that seeks satisfactory solutions in complex scenarios.
- Lossless Compression: A method that allows data to be perfectly reconstructed after compression.
- Lossy Compression: A technique that intentionally discards some data during compression to reduce size.
Licensing and Access
- Creative Commons: A public license facilitating the free distribution of copyrighted works.
- Open Source: Software that is freely available for use and modification.
- Open Access: Research outputs available online without restrictions on access or usage.
