Study Notes

Binary Numbering System

  • Named after its base, which is 2
  • Has 2 digits: 0 and 1
  • Position values for a binary number are 2^x, where x is an exponent, and each position is twice the weight of the preceding one

Importance in Digital Electronics and Computing

  • Used extensively in digital electronics and computing due to ease of representation using switches (0 = "off", 1 = "on")
  • Allows for electronic storage and manipulation of data using digital circuits

Representation and Manipulation

  • Used for representing and manipulating large binary numbers or expressing memory addresses in a compact format
  • Computer programs and programming languages use number system concepts to perform arithmetic operations, store data, and communicate with hardware devices

Binary Arithmetic Operations

  • Addition
    • 0 + 0 = 0
    • 0 + 1 = 1
    • 1 + 0 = 1
    • 1 + 1 = 10 (write 0, carry 1 to the next higher bit)
  • Subtraction
    • 0 - 0 = 0
    • 1 - 0 = 1
    • 1 - 1 = 0
    • 0 - 1 = 1 with borrow from the next higher bit
  • Multiplication
    • 0 * 0 = 0
    • 0 * 1 = 0
    • 1 * 0 = 0
    • 1 * 1 = 1
    • Multiply each digit of the second number by each digit of the first, then sum the results
  • Division
    • Divide a dividend by a divisor to find a quotient and possibly a remainder
    • Subtract in binary, bringing down the next digit
