Study Notes
AP Computer Science Principles - Lesson 2: Binary Number System
- The lesson focuses on converting between binary and decimal number systems, understanding the representation of numbers in computers, and programming errors.
- Students will learn why digital data is converted between binary and decimal representations.
- Students will master converting between binary and decimal number systems.
- Different types of programming errors (logic, syntax, and run-time) will be defined and differentiated.
- Students will learn about and explain overflow errors in numeric representations.
Decimal vs Binary
- Base-10 (Decimal) uses 10 digits (0-9).
- Base-2 (Binary) uses 2 digits (0 and 1).
- Understanding conversions between these systems is key to how computers process data.
0 and 1
- Conversion between decimal and binary systems provides insight into how computers process and store data.
- Learning to do these conversions is helpful for programmers.
- Learning conversions aids in understanding how values are stored and manipulated in a computer's memory.
Representing Numbers
- The decimal system uses 10 digits (0-9).
- Every number can be broken down into its base-10 representation.
- Example decimal numbers (84, 225, and 1376) can be broken down into their base-10 representations.
- Binary uses only 0 and 1.
Binary to Base-2 Conversion
- The base-2 conversion method is explained with example binary numbers (1101, 1001, and 100).
- Binary positions are called bits.
- Bits are usually grouped in bytes of 8 bits.
- Sometimes, bits are grouped in nibbles of 4 bits using a space to separate them.
Binary to Decimal Conversion
- The method for converting binary to decimal is described.
- Converting binary numbers (1010 1101, 0010 1000) to their decimal equivalents is demonstrated using place value.
- The largest possible number in a byte of 8 bits is 255.
Decimal to Binary Conversion
- The method for converting decimal to binary is described.
- Decimal numbers (20, 45, 70, 101, 193, and 204) are converted to their binary equivalent using a table to identify the highest power of 2 that is less than or equal to the decimal number.
- The process is repeated until the remainder is 0.
Signed Numbers
- Binary digits can represent other data forms, not only whole numbers.
- Signed integers use the leftmost bit to signify the sign (0 for positive, 1 for negative).
- The remaining bits represent the magnitude of the value.
