Bits (binary digits) (article) | Khan Academy
In 2 bits, there are four possible values, or combinations: 00, 01, 10, 11. With each additional bit, the number of possible values/combinations goes up by a factor of two.

A Qubit is binary-based, but can hold both 0 and 1 simultaneously. So 1 Qubit can represent as much information as 2 bits.
The solar system (video) | Beyond Earth | Khan Academy
Black holes have two parts. There is the event horizon, which you can think of as the surface, though it's simply the point where the gravity gets too strong for anything to escape.
How long do the courses take? – Khan Academy Help Center

But there's a limit to how large a message can be, since there's a limit to how much data can be reasonably transmitted at once by the physical network connections between devices. That's why many networking protocols split each message into multiple small packets.
Bit rate, bandwidth, and latency (article) | Khan Academy
All of the computing devices on the Internet are communicating in binary. Whether they are connected via wired or wireless, they are sending electromagnetic signals that represent streams of 1s and 0s. Let's explore how those bits are sent and how quickly they can be sent.
Wires, cables, and WiFi (video) | Khan Academy
Bandwidth is measured by bit rate, which is the number of bits that we can actually send over a given period of time, usually measured in seconds. A different measure of speed is the latency, or the amount of time it takes for one bit to travel from one place to another.
Dancer: What I do and how much I make (video) | Khan Academy
We've even had so much time that we've actually rehearsed things or gone over things at the gate, just to buy time. Some people will nap and stretch, but you're with each other all the time. So as a dancer I have a number of responsibilities to do my job well and to be safe and healthy.
