Computers: Present: Tutorial

Binary

In the electronic world, binary is the main building block. Electronic circuits operate on two possibilities, they are either ON or OFF. Understanding this is the basis of Binary. Without binary numbers, modern electronics and computers would ultimately cease to exist. Binary allows a computer to make a decision from input, and produce an output. And from these decisions, today's electronic world was born.
A "1" in binary is evaluated as an ON. A "0" in binary is evaluated as OFF. This value can also symbolize another meaning. Therefore, a "1" in binary is also TRUE and "0" is FALSE. Through these values you get binary logic, which allows a computer to actually "compute".
As you have already learned, each bit is the holder for the value of a binary digit. These bits are grouped together to form a byte. This creates a series of on/off switches that tell the computer what to do.
Have you ever wondered how to convert decimal numbers into binary? Well here's your chance. Below is a simple tutorial, which will educate you on how to convert decimal to binary. If you would rather use a calculator, one has been provided in the Java section.
The calculator is designed to do everything. Built for computer engineers, programmers and even Martians. This calculator converts in between the 4 most important bases: binary, decimal, octal, and hexadecimal. It also performs the 4 functions of a basic calculator: addition, subtraction, division, and multiplication. Enjoy!
If you would like to skip this extra tutorial on converting decimal to binary and vise versa, then please continue what I hope has been a fascinating journey so far. Further your education of computers with the remaining essential bases, in the section Other Bases.
Go learn how to convert to and from binary in the extra tutorial.
