Computer instructions are written in binary, also known as machine code. Computer hardware operates on a series of these binary instructions through pulsating power signals that signify either `OFF`

or `ON`

based on the binary digits `0`

and `1`

respectively.

The binary numbering system is built on a base of `2`

. Every time we reach a power of `2`

, we add another digit. The decimal system works the same way, just with `10`

.

The Least Significant Bit (LSB) is the farthest right digit in a binary number while the Most Significant Bit (MSB) is the leftmost digit. `0`

is an acceptable value for both the MSB and the LSB.

Binary data is any set of expressions that result in a response set of only two answers.

There are four main functions of a computer that make user interaction possible:

- Input
- Processing
- Memory
- Output

- Input is data we give to our computers through interactions- Processing is comprised of the translation of input and the instructions given for output- Memory is used to store either temporary or permanent information- Output is the information that gets returned by the computer
