ELI5: The history of gaming as it refers to 8/16/32/64 bit. What exactly is "bit?" What "bit" are we now?

What exactly does "bit" refer to in gaming? Why did it progress from 8 to 16 to 32 and so on? All I know is that 64 bit was the huge revolution into 3D gaming. What "bit" do we use in this modern era of HD, near photo-realisitic game graphics?

A binary digit, or *bit* for short, is a number that can only be 0 or 1. It's the way computers store information.

Old computers had enough electronics in them to routinely process 8 bits at a time. As computer chips got more transistors on them, newer ones could handle 16 bits at a time, then 32, and now 64 bits at a time is quite common.

The more bits of data you process at once, the more detail you can calculate and draw per second.

Also, the more bits you use to count the locations in your computer's memory chips, the more memory your computer can keep track of.
