binary code Did you know that all of the information that travels through your computer is based on two commands? It’s true. The only data that a computer can understand is on and off. But‚ the millions of combinations of those two commands given in series are what make a computer work. Binary Code Remember the power supply that is inside your computer and how it sends electricity to all of the components? That electricity is what creates an on signal. The memory chips inside your computer

The modern binary number system‚ the basis for binary code‚ was discovered by Gottfried Leibniz in 1679 and appears in his article Explication de l’Arithmétique Binaire. The full title is translated into English as the "Explanation of the binary arithmetic"‚ which uses only the characters 1 and 0‚ with some remarks on its usefulness‚ and on the light it throws on the ancient Chinese figures of Fu Xi."[1] (1703). Leibniz’s system uses 0 and 1‚ like the modern binary numeral system. Leibniz encountered

INTRODUCTION CDMA stands for CODE Division Multiple Access. Code division multiple access ( CDMA ) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access ‚ which is where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this to be achieved without undue interference between theusers CDMA employs spread- spectrum
