Question

What do you call a tiny "switch" that can be set to either on or off?

Short answer

Answer: Bit

Step-by-step solution

Identify the concept

In digital electronics, a "switch" that can be in one of two states (on or off) is called a binary switch or, more commonly, a bit. A bit is the smallest unit of data in computing and digital communication.

Describe the role of a bit

A bit can represent two distinct states, which can be either 0 (off) or 1 (on). Bits are used as the basic building blocks of digital information and processing, as they can be combined to represent more complex data or instructions for computers.
