Logic Gates

The very basis of computers is binary. In electronics everything can be boiled down to 1s and 0s. Logic gates are digital circuits that take one or more binary inputs and produce a binary output. You can check out the basis of logic with Boolean Algebra.

Number Systems

Today, we are going to learn about number systems. A “number system” is defined here as “any notation for the representation of numerals or numbers.” We naturally use the decimal (base 10) system, meaning we use the numbers 0-9 to represent all the other numbers. The three types of number systems that we are going to talk about today are decimal, binary, and hexadecimal, but there are many more!
