Study Notes

In programming, different number systems are used such as binary, decimal, octal, and hexadecimal.
Binary system has a base of 2, decimal system has a base of 10, octal system has a base of 8, and hexadecimal system has a base of 16.
Conversion between number systems can be done manually or using Python functions like bin() for decimal to binary, oct() for decimal to octal, and hex() for decimal to hexadecimal.
Binary numbers are represented by adding a prefix of 0b, octal numbers with 0o, and hexadecimal numbers with `0x before the value.
To convert a binary number to decimal, each digit is multiplied by 2 raised to its position from right to left, and then the results are summed.
The speaker gives homework assignments to practice converting numbers between different systems manually.
Understanding number systems is important for working with bitwise operators in Python.
