The “width” of a wire / the amount of data it can pass.
- Think of it as lanes on a highway. If an input has data bits, then it has “lanes” all of which are ‘s and ‘s
Wires with, lets say 4 data bits, can pass values like 1010 or 0011 or 0000 . You get the idea.
You can use something like a splitter to separate the values into individual, 1 data bit wires like we’re used to.
