Bit

From TPU Reference

A bit is a data value used by binary computing systems. It can do many things but is limited to two states, 0 or 1.

To truly define what a bit is and does we first need to know about how a computer stores, retrieves, and processes information. All the information that makes a computer system run and perform tasks is a string of 1's and 0's each one we refer to as a bit. 1 being a "on" or electrically charged, magneticly charged, or completed circut. 0 being a "off" or neutral charged, neutral magnetic state, or a broken circut. There are some instances where the on/off mapping is reversed.

A bit by itself is almost useless, so they are grouped into bytes, and a byte represents a electrical value(sample)or numerical value. When we combine many bytes we achieve a analog waveform or electrical signal that other electronic devices and or we humans can understand.
