Summary
Computers need to convert data into binary, a system of representing information using only two states: 0 and 1. This conversion is necessary because computers are electronic devices that work with electrical signals, and binary provides a simple way to represent these signals.
Data can be in two forms: analogue and digital. Analogue data is continuous and can have an infinite range of values, like a traditional clock with moving hands. On the other hand, digital data is discrete, represented in distinct steps, like a digital clock with numbers. Converting data to binary allows computers to handle and store information accurately and with less error.
The use of two states in digital systems (0 and 1) is crucial because it simplifies electronic circuits and reduces the chances of errors during data transmission and processing. With just two states, it's easier to differentiate between on and off, representing data more reliably and making computers more dependable.
