Study Notes
Number Systems Overview
- Binary, octal, decimal, and hexadecimal are primary number systems used in computing, each serving unique purposes and efficiencies.
Binary Number System
- Base 2 system using only two digits: 0 and 1.
- Each position represents a power of 2.
- Decimal conversion calculated by summing products of each digit with its positional value (e.g., 101012 = 2^4 + 02^3 + 12^2 + 02^1 + 12^0 = 2110).
Octal Number System
- Base 8 system using digits from 0 to 7.
- Each position indicates a power of 8.
- Conversion to decimal involves summing products of each digit with its positional value (e.g., 7268 = 78^2 + 28^1 + 6*8^0 = 47010).
Hexadecimal Number System
- Base 16 system employs 16 symbols (0-9 and A-F, where A=10, B=11, etc.).
- Decimal conversion performed by summing products of each digit with its positional value (e.g., 2BA16 = 216^2 + 1116^1 + 10*16^0 = 69810).
Decimal Number System
- Base 10 system consisting of digits from 0 to 9.
- Positional values determined by corresponding powers of 10 (e.g., 7089 = 710^3 + 010^2 + 810^1 + 910^0).
Conversion Techniques
-
Decimal to Other Bases:
- Use the division method to convert (e.g., for 2910 to binary, repeatedly divide by 2, recording remainders).
-
Basic Screenshot of Process:
- Dividing the number iteratively while tracking remainders gives the binary equivalent read in reverse order (e.g., 111012).
-
Other Base to Decimal:
- Convert the number to decimal first, then from decimal to the desired base.
Number System Efficiency
- Number systems facilitate efficient data representation:
- Audio, video, graphics, text, etc., represented in binary format in computer architecture.
Learning Objectives
- Differentiate between different number systems and perform conversions among bases.
- Practical exercises to enhance understanding of number system applications.
Assessment Format
- Various assessment methods including fill-in-the-blanks, multiple-choice questions, and conversion tasks to gauge understanding.
Conclusion
- An understanding of number systems is essential for grasping computing concepts and data representation within computer systems.
