How do computers represent information
WebOct 3, 2024 · Data representation. Computers use binary - the digits 0 and 1 - to store data. A binary digit, or bit, is the smallest unit of data in computing. It is represented by a 0 or a 1. Binary numbers are made up of binary digits (bits), eg the binary number 1001. The circuits in a computer's processor are made up of billions of transistors. WebInside a computer exists these switches called transistors Modern computers have billions! Turned off represents 0; Turned on represents 1; Using these transistors we can store values, store data, compute, and do everything we can with computers; David demonstrates how transistors work using light bulbs

WebThat's not a lot of choices, but it's a really important start. With one wire, we can represent a "yes" or a "no," true or false, a one or a zero, or anything else with only two options. This on/off state of a single wire is called a bit, and it's the smallest piece of information the computer can store. If you use more wires, you get more bits.
