The core of computing is binary encoding. The premise is that each of the transistor switches is either on of off, represented by 1 or 0. Each bit is a BI nary digi T. Each of these switches is more-or-less useless on its own.

What is binary? Binary is a number system that only uses two digits: 1 and 0. All information that is processed by a computer is in the form of a sequence of 1s and 0s. There isn't really a 'conversion' that takes place. Binary 1s and 0s is just a virtual representation of the underlying voltages. In fact, in many systems a high voltage might mean 0 while a low voltage means 1.

However, you can arrange them in a sequence to get some logic. Hum ans use hexadecimal representation as a form of shorthand for binary. That's a 16-base number system that goes from 0-9 then a-f, then rolls over from 0f to 10. When you write a computer program, the compiler converts your code into opcode, a hex representation of the binary stream. The CPU interprets the opcodes and follows the program, manipulating bits in the accumulator section. In other words, it reads the binary code and uses that code to switch bits on and off in its 'brain'.

The outgoing data is then sent to various locations in the computer, such as to the sound card, video card, hard disk, RAM, etc. You can do this by mapping each location to a virtual location in the computer. For example, you could set the address 0x2000 to be the sound card, and when you write the data 0x5e41 to 0x2000, the sound card will interpret that data and put out an analog signal to the speakers. You could also read the data at location 0x3000 to see what's on that location in the hard drive. (for example) The exact details require several years of study. The CPU does not 'interpret opcodes' binary codes of 0's and 1's is just a DISPLAY for humans that tells them what is on and what is off for a particular instruction, transistors being switched on and off determine what happens inside a computer. Binary is well suited for computers because it only needs two symbols to represent numbers a 1 and a 0.

In a computer a circuit can be in 2 states on and off hence in the simplest implementation'on' represents a 1 and 'off' a 0. Although it has been argued that 3 states would be the best number syst em for computers,, we still have to use a binary system, because we don't have the hardware necessary to work with a 3-states. All our digital electronics are binary since it is easy to represent two states. There is talk of 4 state quantum computers in which 'qubits' would be used.

The Language of Machines Computers contain millions of —microscopic electronic switches that turn on and off millions of times a second to create the computer experience you're having right now. To process the words, images and sounds we use every day, computers and other devices (such as CD players) transform these communications into a simple code that uses the numerals 0 and 1 to represent the on and off states of a transistor. This language of 0s and 1s is known as digital information. As simple as this language may seem, it is extremely versatile and has played a major role in the greatest technological revolution the world has ever seen. Lesson 1: What is Binary Code? People use all kinds of symbols, sounds, colors and body motions to express themselves. These expressions are, in a sense, codes—signals we use to communicate with one another.

Computers use a special code of their own to express the digital information they process. Oil prices commodities. It's called the code because it consists of only two symbols—0s and 1s. (The 'bi' in 'binary' means two.) Why 0s and 1s? Because those are the only two numbers you need to express the flow of electricity through a transistor.

It's either on or it's off. On is 1, off is 0. Everything you say to a computer has to be put in terms of these two numbers. Lesson 3: How Computers Work With Pictures Picture this.

A computer is made up of millions of electronic switches (transistors). Binary options broker minimum deposit. They're either on or off, open or closed. Free money trade binary options. Now picture this. Your computer screen has hundreds of thousands of dots arranged in rows and columns.
