Key Terms and Definitions (from topics)

• Netiquette: Rules and norms for polite and appropriate online behavior.
• Input Device: Hardware that sends data to a computer (e.g., keyboard, mouse).
• Output Device: Hardware that receives data from a computer (e.g., monitor, printer).
• Measuring Instrument: Tool used to measure electrical or system parameters (e.g., multimeter).
• Binary Number: Base-2 numeral system using digits 0 and 1.
• Decimal Number: Base-10 numeral system using digits 0–9.
• Conversion Method: Process or algorithm to change a number from one base to another.

Important Formulas and Procedures (inferred)

• Binary-to-Decimal Conversion
  • Sum of bits multiplied by powers of 2: decimal = Σ (bit_i × 2^i).
  • Typical step: label least significant bit as 2^0, then sum weighted bits.
• Measuring Instrument Selection
  • Choose instrument by required range, accuracy, safety, and compatibility.
• Maintenance Checklist (typical)
  • Inspect, calibrate, clean, store properly, and document service history.

Action Items / Next Steps

• Review syllabus document for course schedule, learning outcomes, and assessments.
• Study Lesson 1 for expected online behavior and classroom digital conduct rules.
• Read Lesson 2 to understand input and output device types and examples.
• Practice binary-to-decimal conversions using Lesson 4 materials and sample problems.
• Learn instrument types and maintenance steps from Lesson 3; practice with safe procedures.
• Organize files and note page ranges or sections to prioritize study before assessments.

Study Tips

• Start with the syllabus to plan a study schedule aligned with lesson sequence.
• Use practical exercises for binary conversion and device identification.
• Create a maintenance checklist from Lesson 3 and practice with supervised hands-on tasks.
• Summarize netiquette rules into a short personal code for online class interactions.
