Binary

  1. Binary is a base 2 number system.
  2. 0 represents off and 1 represents on
  3. A bit is the minimum unit of binary information stored in a computer system.

Boolean Expressions

  1. A boolean expression is a logical statement that is either TRUE or FALSE and compares data.

Truth Tables

  1. The logical operations shown in truth tables are and, or, not, and XOR.
# AND
5 > 3 and 5 == 3 + 2

True
5 < 3 and 5 == 5

False
5 == 5 or 5 != 5

True
5 < 3 or 5 != 5

False

Real Life Example using Boolean Expressions

Try changing the conditions and/or the logical operation below! Run the code to see if you are eligible to vote.

age = 19
citizen = (True)

if age >= 18 and citizen:
    print("You are eligible to vote.")
else:
    print("You are not eligible to vote.")

You are eligible to vote.

Binary Conversions

Binary to Decimal

  1. We can count in binary by using powers of 2.
  2. In binary, we read from right to left.
  3. 0111 has a value of 7.
  1. For a binary search, the list must be sorted.
  2. In a binary search, computers start at the middle (front,middle,end)/
  3. The number of steps required in a binary search follows the equation: log2(n)+1.
  4. Binary searches also work with a list of strings. We can sort them alphabetically.
  5. Binary searches can be represented in tree diagrams.

Binary Conversions Practice

    1. 10001
  2. Convert the binary number 1010 into decimal.
    1. 10
  3. Convert the decimal number "122" into hexadecimal.
    1. 7A
  4. Convert the hexadecimal number "09" into binary.
    1. 1001

Binary Search Questions

  1. Make a binary search tree of different the list [1,2,4,15,25,30,31]
    1. 31 / \ 25 30 / \ / \ 15 20 31 / \ / \ 4 18 27 / 2
  2. Put this list of strings in a order that can be used for binary search ["Donut”,"Cake”,"Soda”,"Banana”,"Fruit”]
    1. Here is the list in alphabetical order: ["Banana", "Cake", "Donut", "Fruit", "Soda"].
  3. Explain why Binary Search is more efficient than Sequential Search.
    1. Binary search is a more efficient algorithm than sequential search for finding a target value in a sorted list. Binary search works by repeatedly dividing the list in half until the target value is found. This means that binary search only needs to make a logarithmic number of comparisons, while sequential search needs to make a linear number of comparisons.

Octal is a number system that is based on the number 8, using the digits 0 to 7. In contrast, binary is a number system based on the number 2, using only the digits 0 and 1. To convert a binary number to octal, we can split the binary digits into groups of three digits each, starting from the right. Next, we can replace each group of three binary digits with the corresponding octal digit.

Here are the steps to convert a binary number to octal:

Start with a binary number, for example: 1001010. Group the binary digits into groups of three, starting from the right: 1 001 010. Replace each group of three binary digits with the corresponding octal digit: 1 1 2. Write the resulting octal digits together to get the octal equivalent of the binary number: 112. Therefore, to convert a binary number to octal, we need to group the binary digits into sets of three, then replace each set with the corresponding octal digit. This process helps us to quickly convert between binary and octal representations.
