Binary numbers form the basis of computing systems. Binary numbers contain only the digits 0 or 1, or bits, where each bit represents a power of two. To convert binary to decimal, multiply each bit by its …

Before exploring how the binary system works, let's revisit our old friend, the decimal system. When you learned how to count, you might have learned that the right-most digit is the "ones' place", the next is …

Learn a technique for converting decimal numbers into binary numbers using just pen, paper, and calculations. Works best for small numbers, since bigger numbers require increasingly more …

The most used ones, base 10 is used very heavily, binary and there's also hexadecimal where you don't have two digits or not 10 digits, but you have 16 digits. And we'll explore those in future videos and …

We just described the binary search algorithm in English, stepping through one example. That's one way to do it, but a human language explanation can vary in quality.

Why do computers represent information in such a hard to read way? And how can 1s and 0s represent so many different things? That's what we'll explore in this lesson. To start off, check out the next …

Bitwise simply means that we are dealing with individual bits, or binary numbers. In any modern/computerized encryption scheme we represent our symbols using binary digits.

Computers use bits (binary digits) to represent data as ones and zeroes. Bits are the smallest piece of information a computer can store. Explore how computers use the binary number system to …

In this unit on how computers work, we're mostly going to be dealing with binary numbers. It's important to understand the hexadecimal system as well though, because they'll pop up throughout later units …

That's the beauty of Huffman coding: the algorithm gives us a way to come up with a set of binary codes for a given sequence that ensures the data can be reconstructed unambiguously and reliably.
