Study Notes
Logic Gates and Truth Tables
- Truth tables display output values of logic gates based on input combinations.
- An OR gate outputs 1 if at least one input is 1; its truth table includes rows: 00 → 0, 01 → 1, 10 → 1, 11 → 1.
- AND gate requires all inputs to be 1 for a 1 output; input combinations are essential in determining outputs in circuits.
Computer Components Hierarchy
- Components of a computer are structured from high-level to low-level: computer, integrated circuit, logic gate, transistor.
- Each level serves a different computational function, from simple to complex operations.
File Sizes in Computing
- Understanding file sizes helps organize data; sizes are typically listed from largest to smallest.
- Examples include files such as "reunion.mov" (15 GB) and "notes.txt" (450 B).
Circuit Inputs and Outputs
- Inputs in circuits directly affect outputs; for example, for an AND gate leading to an OR gate, if the output is 111 and input C is 111, combinations of inputs A and B include 00, 01, 10, and 11.
Binary Representation
- Computers utilize binary number system for number representation in memory.
- One wire can represent two states (on/off), therefore, three wires represent three bits of information (2^3 = 8 combinations).
- Minimum bits required to represent two options are 2 (as 2^2 = 4).
Logic Gate Functionality
- A logic gate outputs either 0 or 1 based on specific Boolean functions, linking inputs to outputs critically in circuit design.
File Format Conversions
- Changing image file formats (e.g., GIF to JPEG) requires editing software to export the required file type before uploading.
Digital Alarm Clock Indicators
- Digital clocks can represent specific indicators with a single bit, such as temperature unit (C/F) and AM/PM status.
Binary Digit Values
- A binary digit (bit) can only represent two values: 0 or 1, foundational to digital computing and data representation.
